    Before H E N RY, L UC ER O, and M cCO NNELL, Circuit Judges.
    H E N RY, Circuit Judge.
    Claimant Nick L. Blea appeals from a magistrate judge’s order affirming
    the Commissioner’s denial of his application for disability insurance benefits
    under Title II of the Social Security Act. M r. Blea contends that the magistrate
    judge erred in upholding the administrative law judge (ALJ)’s decision, where the
    ALJ failed to: (1) utilize Social Security Ruling (SSR ) 83-20 to determine the
    onset date of M r. Blea’s disabilities, and (2) confront or address lay witness
    testimony pursuant to Social Security Rulings 83-20 and 85-16. W e hold the
    onset date of M r. Blea’s disabilities was ambiguous, that the ALJ erred by failing
    to utilize SSR 83-20 to infer an onset date, and that the ALJ should have
    addressed lay witness testimony in his written decision. Therefore, exercising
    jurisdiction pursuant to 42 U.S.C. § 405(g) and 28 U.S.C. § 1291, we reverse and
    remand for further proceedings consistent with this opinion.
    I. BACKGROUND
    In July 1997, M r. Blea’s brother shot him in the foot. M r. Blea endured a
    series of seven surgeries over the next two months, and numerous visits w ith
    doctors thereafter. In January 1998, M r. Blea’s treating physician, Dr. W illiam L.
    Ritchie, M .D., provided him with a handicapped parking placard, and wrote in his
    treatment notes that M r. Blea’s “pain is probable [sic] due to the bony
    deformities, although there is the possibility that it is due to incomplete fusion of
    the bone graft.” Aplt’s App. vol. I, at 161. Dr. Ritchie also noted that despite the
    2
    pain, M r. Blea was “able to ambulate with minimal restrictions.” 
    Id. In February,
    Dr. Ritchie again saw M r. Blea, who “return[ed] complaining
    of continued foot pain.” 
    Id. at 159.
    Dr. Ritchie prescribed ibuprofen and
    D arvocet-N , advised M r. B lea to use a cane, and referred him to Dr. Laura A.
    M itchell, M .D., a foot and ankle specialist. After examining him in M arch, Dr.
    M itchell noted that his x-rays revealed a “lateral shift of the lesser metatarsals
    and some shortening of the first ray.” 
    Id. at 157.
    She further explained that M r.
    Blea was “doing well and is not interested in further surgery.” 
    Id. at 156.
    M r.
    Blea did not see another physician until June 1998, when he tripped while
    carrying his child. That doctor diagnosed M r. Blea with a broken toe, and noted
    that “[h]e has no pain proximally where he had the previous bone graft.” 
    Id. at 154.
    Although the doctor he saw at this time recommended that M r. Blea make
    an appointment to follow up with Dr. Ritchie in a few weeks, M r. Blea did not
    seek medical treatment again until January 2000.
    At the January 2000 visit, Dr. Ritchie noted that the w ounds from surgery
    and the injury itself were “well healed.” 
    Id. at 153.
    The x-rays showed “some
    degenerative changes” in M r. Blea’s foot; however, “no acute changes [were]
    noted.” 
    Id. He recommended
    that M r. Blea see Dr. M itchell again. But, at his
    February 2000 visit, Dr. M itchell diagnosed M r. Blea with “significant post-
    traumatic arthritis with constant pain.” 
    Id. at 150.
    She discussed the possibility
    of a Syme’s amputation – an amputation of the entire foot at the ankle – w ith M r.
    3
    Blea at this visit. Further, in February 2002, M r. Blea saw Dr. Robert C.
    Schenck, M .D., who indicated that M r. Blea’s x-rays “reveal[ed] fairly significant
    midfoot and forefoot arthritis.” 
    Id. at 197.
    Dr. Schenck also recommended that
    M r. Blea apply for social security benefits: “in my opinion, he is permanently
    fully disabled and unemployable.” 
    Id. at 198.
    M r. Blea followed Dr. Schenck’s advice. In M arch 2002, he applied for
    disability insurance benefits under Title II of the Social Security Act and
    supplemental social security income under Title XVI, alleging he was disabled
    due to post-traumatic arthritis and depression as of June 1997. W hile his claim
    for benefits was pending, M r. Blea met with Dr. Elegio R. Padilla, Ph.D., on
    August 28, 2002, one of the Social Security Administration’s consultative
    psychologists. This was the first time M r. Blea received any medical treatment
    for his depression. During the evaluation, M r. Blea revealed his past suicidal
    thoughts, described his problems with alcohol, and discussed the emotional
    ramifications of having been shot by his own brother. Dr. Padilla concluded that
    M r. Blea “has been dysthymic for years and may be suffering from a major
    depression currently.” 
    Id. at 246.
    The Commissioner initially denied M r. Blea’s claims for disability
    insurance and supplemental income. Upon reconsideration in October 2002,
    however, M r. Blea was found to be disabled and entitled to supplemental security
    income as of M arch 1, 2002. “The decision was made on the basis that at the
    4
    time the application was protectively filed, M arch 9, 2002, the claimant’s post
    traumatic arthritis and dysthymia were medically determinable impairments that
    were disabling.” 
    Id. at 18.
    Thus, the Commissioner determined that, as of at
    least M arch 1, 2002, M r. Blea was disabled due to both post-traumatic arthritis
    and dysthymia. Nonetheless, the Commissioner denied M r. Blea’s application for
    disability insurance because she determined that any impairments M r. Blea had
    were “not disabling on any date through 12/31/98 the last day insured status for
    disability was met.” 
    Id. at 42.
    After the denial of his claim for disability insurance benefits, M r. Blea
    requested a hearing before an ALJ, which was held in September 2003. During
    the hearing, M r. Blea testified about the effects of having been shot in the foot.
    M rs. Blea also testified. She reported that after the gunshot injury and for months
    thereafter, her husband talked about suicide. Even recently, she testified, “he
    talks about it probably at least two to three times a week . . . he says that the pain
    is too much to bear.” 
    Id. at 333.
    She also explained that since the gunshot injury,
    M r. Blea has rarely left the house due to pain and anxiety, and has also been
    unable to sleep comfortably. At the close of the evidence, M r. Blea’s attorney
    asked that the ALJ call a medical expert to assist the ALJ in reviewing the
    medical evidence. The ALJ denied this request because he found “no medical –
    or no psychiatric evidence relating to [the time before Dec. 31, 1998] which [he]
    feel[s] warrants that review.” 
    Id. at 342.
    5
    In November 2003, the ALJ denied M r. Blea’s claim for disability
    insurance benefits because he decided that M r. Blea had not been disabled as of
    the date he last was eligible for disability benefits, December 31, 1998. The ALJ
    did not, however, determine an exact onset date. Rather, the ALJ applied the
    five-part sequential analysis mandated by 20 C.F.R. §§ 404.1520 and 416.920,
    and determined that because M r. Blea retained the capacity for sedentary work as
    of December 31, 1998, he could not have been disabled.
    W ith respect to M r. Blea’s depression, the A LJ found that M r. Blea’s
    allegations about his physical limitations due to the condition were not well
    supported by the medical record. Additionally, his reports of depression were not
    credible before December 31, 1998 since there was no evidence of treatment or
    reports of depression before that date. Thus, the A LJ did not consider M r. Blea’s
    claim of depression in determining what kind of residual capacity for work M r.
    Blea retained.
    W ith respect to his post-traumatic arthritis, the ALJ applied the five-step
    sequential analysis pursuant to 20 C.F.R. §§ 404.1520 and 416.920 to determine
    whether M r. Blea was disabled as of that date. M r. Blea carried the burden of
    proof with respect to the first four parts of the test.
    The first part inquires whether the claimant has performed substantial
    gainful activity since the alleged onset date; if he has, he is not disabled. The
    ALJ found that M r. Blea had not performed substantial gainful activity since the
    6
    gunshot wound. The second part asks whether the claimaint’s impairments are
    severe, which they must be if he is to be found disabled. The A LJ found that M r.
    Blea’s impairment due to post-traumatic arthritis was severe.
    If the claimant has not performed gainful activity and his impairments are
    severe, then the ALJ must determine whether his impairments are listed in the
    Regulations. If the impairments are listed, then the ALJ must find the claimant
    disabled without further inquiry. At this step, the ALJ determined that “[t]he
    claimant’s musculoskeletal impairments did not approach the severity required to
    meet listings, § 1.00 prior to December 1998. M r. Blea retained the ability to
    ambulate effectively . . . .” Aplt’s App. at 21. Thus, the ALJ proceeded to the
    fourth step of the inquiry, whether the impairments prevent M r. Blea from
    performing his past relevant work. The ALJ found that after the gunshot injury,
    M r. Blea could no longer perform his relevant past work, even before December
    31, 1998.
    Once the claimant has carried his burden through the first four parts, the
    burden shifts to the Commissioner for the fifth and final part, to show that other
    work, which the claimant could perform given his residual functional capacity,
    existed in significant numbers in the national economy such that the claimant
    could have been employed. If the Commissioner can make this showing, then the
    ALJ must find that the claimant is not disabled. The ALJ found that as of
    December 31, 1998 M r. Blea retained the ability to do sedentary work, relying
    7
    heavily on the testimony of an impartial vocational expert. The ALJ additionally
    noted that, in M arch 1998, M r. Blea and his doctors w ere satisfied with the results
    of his surgeries, in June 1998, he walked well enough to carry a baby, and he did
    not seek medical treatment again until January 2000. Based on these factors, the
    ALJ decided that it was reasonable to believe that M r. Blea did not have severe,
    debilitating pain during the relevant time period. Therefore, the ALJ concluded
    that M r. Blea’s allegations of complete disability due to post-traumatic arthritis
    were not supported by the medical record before his last insured date of
    December 31, 1998.
    M r. Blea requested the Appeals Council to reverse the ALJ, providing
    additional evidence from one of his treating orthopedists, Dr. Schenck. Dr.
    Schenck offered the opinion that “it is reasonable to assume that M r. Blea’s post-
    traumatic arthritis with constant pain was present between June 1998 and January
    2000.” See A plt’s A pp. at 309. The Appeals Council, however, declined review ,
    stating in a form decision that it had “considered the additional evidence listed.”
    
    Id. at 6.
    W hen the Appeals Council declined review, the ALJ’s decision became
    the final decision of the Commissioner.
    M r. Blea appealed the ALJ’s decision to the federal district court, arguing
    that the ALJ erred by not applying SSR 83-20 to determine the onset date of his
    disabilities. He also contended that the ALJ’s failure to address the evidence
    provided by lay witnesses constituted reversible error. A magistrate judge issued
    8
    judgment pursuant to 28 U.S.C. § 636(c), holding that the ALJ’s decision was
    supported by substantial evidence. This appeal followed.
    II. D ISC USSIO N
    “W e review the [magistrate judge’s] decision de novo and independently
    determine whether the ALJ’s decision is free from legal error and supported by
    substantial evidence.” Fischer-Ross v. Barnhart, 
    431 F.3d 729
    , 731 (10th Cir.
    2005). Substantial evidence is “such relevant evidence as a reasonable mind
    might accept as adequate to support a conclusion.” Fowler v. Bowen, 
    876 F.2d 1451
    , 1453 (10th Cir. 1989) (internal quotation marks omitted). W e will not
    reweigh the evidence or substitute our judgment for the Commissioner’s. Qualls
    v. Apfel, 
    206 F.3d 1368
    , 1371 (10th Cir.2000). “B ecause the Appeals Council
    denied review, the ALJ’s decision is the Commissioner’s final decision for
    purposes of this appeal.” M adrid v. Barnhart, 
    447 F.3d 788
    , 789-90 (10th Cir.
    2006). W e note that any new evidence submitted to the Appeals Council on
    review “becomes part of the administrative record to be considered when
    evaluating the Secretary’s decision for substantial evidence.” O’Dell v. Shalala,
    
    44 F.3d 855
    , 859 (10th Cir. 1994) (reasoning that “because the Secretary’s
    decision does not become final until after the Appeals Council denies review or
    issues its own findings, her ‘final decision’ necessarily includes the Appeals
    Council’s conclusion that the ALJ’s findings remained correct despite the new
    9
    evidence.”).
    M r. Blea presents two main arguments on appeal. First, he contends that
    the ALJ should have utilized Social Security Ruling 83-20, Program Policy
    Statement: Title II and XVI: Onset of Disability (PPS-100), 1983 W L 31249
    (S.S.A. 1983)(“SSR 83-20”) to determine the onset date of his disabilities.
    Second, M r. Blea argues that the A LJ’s failure to analyze M rs. Blea’s lay witness
    testimony constitutes reversible error, citing Tenth Circuit precedent, as well as
    the regulations SSR 83-20, and Social Security Ruling 85-16, Program Policy
    Statement: Titles II and XVI: Residual Functional Capacity for M ental
    Impairments (PPS-120), 1985 W L 56855 (S.S.A. 1985)(“SSR 85-16), which
    instruct an ALJ to consider lay witness testimony. W e examine each argument
    below .
    A.    Application of SSR 83-20
    To qualify for disability benefits, a claimant must establish that he is
    “disabled” under the Social Security Act, 42 U.S.C. § 423(a)(1)(E) (the “Act”).
    The Act states that “disability” is the “inability to engage in any substantial
    gainful activity by reason of any medically determinable physical or mental
    impairment which . . . has lasted or can be expected to last for a continuous
    period of not less than 12 months.” 
    Id. § 423(d)(1)(A).
        It is not disputed that
    M r. Blea is currently disabled under the Act. W hat is in dispute is when M r. Blea
    became disabled. This is problematic for M r. Blea because he only qualifies for
    10
    disability benefits if he can show that he was disabled prior to his last insured
    date – December 31, 1998. See 
    id. § 423(c).
    On appeal, M r. Blea presents two arguments regarding why the ALJ should
    have applied SSR 83-20 to determine the onset date of his disabilities. First, M r.
    Blea contends that his post-traumatic arthritis is of traumatic origin under SSR
    83-20 because it was caused by the gunshot wound and presented within twelve
    months of the gunshot incident, thereby making the onset date of his disability
    June 1997 – the date of the gunshot injury. Alternatively, he argues that even if
    his post-traumatic arthritis and dysthymia are not of traumatic origin, the ALJ
    comm itted reversible error by failing to follow SSR 83-20’s provisions for calling
    a medical advisor. Before addressing M r. Blea’s arguments, we examine SSR 83-
    20 and discuss what it requires of an ALJ.
    1.     SSR 83-20
    SSR 83-20 is “binding on all components of the Social Security
    Administration,” including ALJs, 20 C.F.R. § 402.35(b)(1), and sets forth an
    analytical framework for assessing the date of onset for a disability of traumatic
    or non-traumatic origin. It provides that a disability is of “traumatic origin,”
    where after the date of injury, “the individual is thereafter expected to die as a
    result or expected to be unable to engage in substantial gainful activity (SG A) (or
    gainful activity) for a continuous period of at least 12 months.” SSR 83-20, at 2.
    W here a disability is of traumatic origin, the date of onset is the date of the
    11
    traumatic injury. 
    Id. Additionally, SSR
    83-20 provides a framew ork for examining injuries that
    are not considered of “traumatic origin” under the regulation. SSR 83-20 states
    that “[i]n disabilities of nontraumatic origin, the determination of onset involves
    consideration of the applicant’s allegations, work history, if any, and the medical
    and other evidence concerning impairment severity.” 
    Id. The date
    alleged by the
    claimant is the starting point for determining disability onset, and the date the
    claimant stopped working is also of significance in selecting the onset date. 
    Id. M edical
    evidence, however, is the “primary element” for the onset determination,
    as the onset date “can never be inconsistent with the medical evidence of record.”
    
    Id. at 2-3.
    SSR 83-20 also provides that, when medical evidence does not establish the
    precise onset date, the ALJ may have to “infer the onset date from the medical
    and other evidence that describe the history and symptomatology of the disease
    process.” 
    Id. at 2.
    The regulation provides two examples of situations w here it
    may be necessary to infer an onset date: (1) in the case of a slowly progressing
    impairment, “w hen, for example, the alleged onset and the date last worked are
    far in the past and adequate medical records are not available,” and (2) when
    “onset of a disabling impairment(s) occurred some time prior to the date of the
    12
    first recorded medical examination.” 1 
    Id. at 3.
    “A t the hearing, the [ALJ] should
    call on the services of a medical advisor when onset must be inferred.” 
    Id. 2. Traumatic
    Origin Provisions of SSR 83-20
    M r. Blea contends that his disabilities are of traumatic origin under SSR
    83-20, and therefore the onset date should be the date he was shot in the foot -
    June 1997. The A LJ, without explicit consideration of SSR 83-20, did not use
    this date, finding that “M r. Blea’s [gunshot] wound initially heeled [sic] well and
    he displayed minimal pain in the foot.” Aplt’s App. vol. I at 21.
    On appeal, M r. Blea renews his argument that the ALJ’s implicit decision
    that his disability was not of traumatic origin was unsupported by the medical
    evidence and contrary to SSR 83-20. He states that “[t]he twelve month
    requirement under SSR 83-20 was met when, according to the evidence,
    claimant’s disabling post-traumatic arthritis had developed as a result of his
    injury of June 1997 and had presented itself by the following year in June 1998.”
    Aplt’s Br. at 10. The government responds that the medical evidence available
    1
    At oral argument, the attorney representing the Commissioner contended
    that SSR 83-20 did not apply to M r. Blea’s case because the plain wording of SSR
    83-20 stated that a medical advisor w as only required if the onset of a disability
    occurred prior to the date of the first recorded medical examination. As the
    Commissioner is well aware, we do not generally address arguments made for the
    first time at oral argument. United States v. Gonzalez-Coronado, 
    419 F.3d 1090
    ,
    1094 n.7 (10th Cir. 2005). W e further note, however, that this argument
    misconstrues SSR 83-20, which, as we explain above, requires the assistance of a
    medical advisor w henever “onset” must be inferred.
    13
    from June 1997 to June 1998 shows that M r. Blea had been steadily improving
    and could ambulate effectively; thus, the ALJ correctly decided that the onset date
    of M r. B lea’s impairments did not correspond to the gunshot injury.
    W e begin our analysis of M r. Blea’s argument by noting that SSR 83-20
    and our precedent do not require an ALJ to consult with a medical advisor to
    determine whether a disability is of traumatic origin. W e have previously held
    that “a medical advisor need be called only if the medical evidence of onset is
    ambiguous.” Reid v. Chater, 
    71 F.3d 372
    , 374 (10th Cir. 1995). If a disability is
    of traumatic origin, the onset date would not be ambiguous; indeed, it would most
    often be “self-evident.” M ason v. Apfel, 
    2 F. Supp. 2d 142
    , 149 (D . M ass. 1998).
    Thus, our task at this point is to determine if the A LJ’s decision that M r. Blea’s
    onset date was not the date of the gunshot injury comported with the traumatic-
    injury provisions of SSR 83-20 and was supported by substantial evidence.
    M r. Blea asserts that symptoms of his post-traumatic arthritis presented
    sometime in the twelve months after the gunshot injury, but he does not cite any
    part of the record that supports this assertion, even though the record contains
    ample medical evidence for the time period June 1997 to June 1998. Our review
    of the record shows that at the time of the gunshot wound, and during the healing
    process thereafter, there were no indications that M r. Blea was “expected to be
    unable to engage in substantial gainful activity . . . for a continuous period of at
    least 12 months” due to post-traumatic arthritis or dysthymia. SSR 83-20, at 2.
    14
    Although M r. Blea still suffered from pain, by January 1998, seven months
    after the injury, he was “able to ambulate with minimal restrictions.” Aplt’s App.
    vol. I at 161. In M arch 1998, he sought the advice of a foot and ankle specialist,
    who prescribed a new orthotic to assist M r. Blea in w alking. The specialist’s
    notes state that, besides some numbness, M r. Blea was “doing well and is not
    interested in any further surgery.” 
    Id. at 156.
    Finally, a doctor’s notes from June
    1998 indicate that M r. Blea had “no pain proximally where he had the previous
    bone graft,” supporting the ALJ’s conclusion that M r. Blea was not exhibiting
    symptoms of post-traumatic arthritis at that visit. 
    Id. at 154.
    Therefore, we
    conclude that the ALJ’s decision not to use the date of the gunshot as the onset
    date did not conflict with SSR 83–20, and that it was supported by substantial
    evidence.
    3.     Provisions of SSR 83-20 Relating to Slowly Progressing Impairments
    The issue of whether M r. Blea’s disabilities are slowly progressive
    impairments, where “[d]etermining the proper onset date is particularly difficult,”
    SSR 83-20 at 3, is a much closer question. M r. Blea contends that even if the
    provisions of SSR 83-20 relating to traumatic origin do not apply to this case, the
    ALJ erred by failing to call a medical advisor to assist in setting an onset date.
    The Commissioner replies that the ALJ was not obligated to consult with a
    medical advisor because there was substantial evidence to conclude, at step five
    of the five-step sequential analysis, that M r. Blea retained the capacity to perform
    15
    sedentary work.
    W e begin by rejecting the Commissioner’s position because it fails to
    address the crux of the issue. The ALJ’s finding of residual functional capacity at
    step five does not mean that the ALJ can ignore the clear directives of SSR 83-20,
    which is “binding on all components of the Social Security Administration.” 20
    C.F.R. § 402.35(b)(1).
    It is important to understand that the issue of whether a medical advisor
    is required under SSR 83-20 does not turn on whether the ALJ could
    reasonably have determined that [the claimant] was not disabled before
    [her last insured date]. Rather, when there is no contemporaneous
    medical documentation, we ask whether the evidence is ambiguous
    regarding the possibility that the onset of her disability occurred before
    the expiration of her insured status. If the medical evidence is
    ambiguous and a retroactive inference is necessary, SSR 83-20 requires
    the ALJ to call upon the services of a medical advisor to insure that the
    determination of onset is based upon a “legitimate medical basis.”
    Grebenick v. Chater, 
    121 F.3d 1193
    , 1200-1201 (8th Cir. 1997). Additionally,
    we note that when an onset date is ambiguous, it is not usually possible for an
    ALJ to make a decision that is supported by substantial evidence. Finally, the
    Commissioner’s position ignores the possibility that a medical advisor’s
    assistance could change the ALJ’s determination at step three (the listed
    impairment step) of the five-step inquiry, thereby obviating any need to examine
    residual functional capacity at step five.
    In contrast to the Commissioner’s argument, our precedent clearly
    establishes that where “medical evidence of onset is ambiguous,” an ALJ is
    16
    obligated to call upon the services of a medical advisor. Reid v. Chater, 
    71 F.3d 372
    , 374 (10th Cir. 1995); see also 
    Grebenick, 121 F.3d at 1201
    (“If the medical
    evidence is ambiguous, and a retroactive inference is necessary, SSR 83-20
    requires the ALJ to call upon the services of a medical advisor to insure that the
    determination of onset is based upon a ‘legitimate medical basis.’”); see also
    Bailey v. Chater, 
    68 F.3d 75
    , 79 (4th Cir. 1995) (“[I]f the evidence of onset is
    ambiguous, the ALJ must procure the assistance of a medical advisor in order to
    render the informed judgment that the Ruling requires.”). Proceedings before an
    ALJ are not inquisitorial; rather, “[a]n ALJ [has] a duty to develop a full and fair
    record, and therefore must consult a medical advisor” when evidence of onset is
    ambiguous. See Henderson v. Apfel, 
    179 F.3d 507
    , 513 (7th Cir. 1999) (internal
    quotation marks omitted). “In the absence of clear evidence documenting the
    progression of [the claimant’s] condition, the ALJ [does] not have the discretion
    to forgo consultation with a medical advisor.” 
    Bailey, 68 F.3d at 79
    .
    Thus, the issue of whether the ALJ erred by failing to call a medical
    advisor turns on whether the evidence concerning the onset of M r. Blea’s
    disabilities was ambiguous, or alternatively, whether the medical evidence clearly
    documented the progression of his conditions. Below, we examine the medical
    record w ith respect to both of M r. Blea’s disabilities. W e conclude that M r.
    Blea’s medical record was ambiguous, did not clearly document the progression
    of his impairments, and presented a situation where the ALJ needed to infer an
    17
    onset date both for M r. Blea’s dysthymia and post-traumatic arthritis.
    Therefore, we remand this case to the ALJ with instructions to follow the
    provisions of SSR 83-20 and call a medical advisor. 2
    a.     Post-Traumatic A rthritis
    The ALJ found that M r. Blea did not prove he suffered from post-traumatic
    arthritis prior to December 31, 1998, relying primarily on three inferences he
    made from the medical evidence in the record. First, at a M arch 1998 visit with a
    specialist, M r. Blea indicated that he was not interested in further surgery. “It is
    reasonable to infer then, that he was at least partially satisfied with the result of
    the surgery he had before.” Aplt’s App. vol. I, at 22. Second, with respect to M r.
    Blea’s June 1998 visit to a doctor for treatment after stubbing his toe while
    carrying his child, the ALJ determined that “it is apparent that at that time, he was
    able to ambulate effectively enough to feel comfortable carrying his baby.” 
    Id. 2 W
    e need not scrutinize M r. Blea’s ancillary argument that the Appeals
    Council erred by not analyzing new evidence from one of M r. Blea’s treating
    physicians. In denying review of the ALJ’s decision, the Appeals Council stated
    “we considered the additional evidence listed. . . . W e found that this information
    does not provide a basis for changing the Administrative Law Judge’s decision.”
    Aplt’s App. vol. I at 6-7. The Social Security Administration’s regulations
    “require[] the Appeals Council to consider evidence submitted with a request for
    review.” Threet v. Barnhart, 
    353 F.3d 1185
    , 1191 (10th Cir. 2003). However,
    where as here, the Appeals Council states that it has considered the additional
    evidence, “our general practice, which we see no reason to depart from here, is to
    take a lower tribunal at its word when it declares that it has considered a matter.”
    Hackett v. Barnhart, 
    395 F.3d 1168
    , 1173 (10th Cir. 2005). Because we remand
    this case to the ALJ, we need not determine whether the medical evidence here is
    so strong as to require a change in our general practice.
    18
    Third, with respect to the gap in medical evidence from June 1998 to January
    2000, the A LJ stated that “[i]t stands to reason that if the claimant’s pain w as so
    severe as to be completely debilitating as alleged, he would have sought medical
    attention throughout this period.” 
    Id. These inferences
    are not reasonable because they do not necessarily flow
    from the facts. First, it is equally reasonable to think that M r. Blea declined
    further surgery because he did not wish to endure another painful process–an
    eighth surgery–as it is to think that he was not interested in surgery because he
    was fully recovered. Second, although he carried his child, he may have done so
    out of necessity–not because he was fully recovered. Third, as other evidence
    suggested, it is also reasonable to infer that the gap in medical treatment
    occurred, not because M r. Blea felt better, but because he was dysthymic and
    dependent on alcohol.
    Thus, we find these inferences insufficient to support the ALJ’s decision in
    light of the requirements of SSR 83-20. M r. Blea’s medical record is indisputably
    incomplete during a pertinent time period, June to December 1998. But, rather
    than “call[ing] on the services of a medical advisor w hen onset must be inferred,”
    the ALJ made negative inferences against M r. Blea due to the gap in the medical
    record. SSR 83-20 at 3. An ALJ may not make negative inferences from an
    ambiguous record; rather, it must call a medical advisor pursuant to SSR 83-20.
    
    Reid, 71 F.3d at 374
    . “The requirement that, in all but the most plain cases, a
    19
    medical advisor be consulted prior to inferring an onset date is merely a variation
    on the most pervasive theme in administrative law–that substantial evidence
    support an agency’s decisions.” 
    Bailey, 68 F.3d at 80
    .
    In this regard, we find the Fourth Circuit’s opinion in Bailey v. Chater, 
    68 F.3d 75
    , particularly instructive. In Bailey, a claimant had a number of ailments
    that he acquired over a few years, including diabetes, anxiety, high blood
    pressure, and allergies. The A LJ had fixed the claimant’s onset date two years
    after the date on which she had asserted her disability began. The Fourth Circuit
    reversed and remanded with instructions for the ALJ to call a medical advisor
    pursuant to SSR 83-20 because the “evidence regarding the onset date is
    ambiguous. . . . In the absence of clear evidence documenting the progression of
    [the claimant’s] condition, the ALJ did not have the discretion to forgo
    consultation with a medical advisor.” 
    Id. at 79.
    As in Bailey, the ALJ lacked “clear evidence documenting the progression”
    of M r. Blea’s post-traumatic arthritis. 
    Id. In June
    1998, six months before his
    last-insured date, M r. Blea appeared not to be experiencing a significant amount
    of pain; however, by January 2000, approximately one year after his last-insured
    date, M r. Blea exhibited symptoms, including complaints of pain, difficulty
    walking, and degenerative changes present on x-rays. The condition was
    advanced enough by February 2000 to permit a treating physician to diagnose him
    with “significant post-traumatic arthritis.” Aplt’s App. vol. I, at 150. W ith respect
    20
    to the critical time, June 1998 to December 1998, however, the medical record
    before the ALJ was silent. Therefore, the ALJ should have called a medical
    advisor to assist in making reasonable inferences.
    W e note that on appeal, we have the benefit of a letter from Dr. Schenck,
    one of M r. Blea’s treating physicians. See O’Dell, 
    44 F.3d 859
    (holding that any
    new evidence submitted to the Appeals Council on review “becomes part of the
    administrative record to be considered when evaluating the Secretary’s decision
    for substantial evidence.”) In this letter, w hich was provided only to the Appeals
    Council, not to the ALJ, Dr. Schenck opines that “it is reasonable to assume that
    M r. Blea’s post-traumatic arthritis with constant pain was present between June
    1998 and January 2000.” Aplt’s App. vol. I at 309. This letter further
    undermines the ALJ’s decision because “[a]n ALJ is required to give controlling
    weight to a treating physician’s well-supported opinion, so long as it is not
    inconsistent with other substantial evidence in the record.” Drapeau v.
    M assanari, 
    255 F.3d 1211
    , 1213 (10th Cir. 2001). On remand, the A LJ must
    address Dr. Schenck’s opinion, as it is now part of the medical record.
    b.    Dysthymia
    The ALJ declined to consider M r. Blea’s claim that his dysthymia disabled
    him as of June 1997, noting:
    a review of the medical record failed to provide any docum entation of
    alleged depression or treatment for depression before D r. Padilla’s
    evaluation of the claimant on August 28, 2002. M r. Blea reported long-
    21
    standing depression in that examination interview but the record did not
    support the claimant’s subjective report. Due to the complete lack of
    treatment or even the report of depression prior to December 1998, this
    impairment is not considered prior to the claimant’s date last insured.
    Aplt’s App. vol. I, at 21. M r. Blea contends that the ALJ’s findings are not
    supported by substantial evidence because Dr. Padilla’s evaluation specifically
    noted that M r. Blea had “been dysthymic for years.” 
    Id. at 246.
    Additionally, he
    argues that the ALJ should have called a medical advisor to “further address[] the
    onset of claimant’s depression.” Aplt’s Br. at 16. The Commissioner contends
    that the ALJ correctly disposed of M r. Blea’s dysthymia claim because M r. Blea
    failed to provide medical evidence of his depression prior to his last insured date.
    The Commissioner’s argument and the ALJ’s decision both contradict the
    clear dictates of SSR 83-20, which specifically provides, as an example of when
    an ALJ should call a medical advisor, the situation where “the onset of a
    disabling impairment[] occurred some time prior to the date of the first recorded
    medical examination.” SSR 83-20 at 3. Additionally, we note that the A LJ’s
    reasoning is at tension with the C ommissioner’s earlier determination that there
    was sufficient medical evidence for the Commissioner to determine that, as of at
    least M arch 1, 2002, M r. Blea’s dysthymia w as a “medically determinable
    impairment [] that [was] disabling,” a date prior to any treatment or report of
    depression. Aplt’s App. vol. I, at 18.
    As we described above, the ALJ “should call on the services of a medical
    22
    advisor when onset must be inferred.” SSR 83-20, at 3. The ALJ erred by failing
    to call a medical advisor “in the absence of clear evidence documenting the
    progression of [the claimant’s] condition.” 
    Bailey, 68 F.3d at 79
    . Therefore, on
    remand, the ALJ should apply SSR 83-20 and call a medical advisor with respect
    to M r. B lea’s claim of dysthymia as well.
    B.       Failure to Consider Lay-W itness Testimony
    W e next examine M r. Blea’s contention that the ALJ’s decision requires
    remand because of the ALJ’s failure to discuss or consider the lay testimony of
    his wife. Becky Blea, M r. Blea’s wife since 1994, testified before the ALJ about
    M r. Blea’s depression, as well as his problems with his foot that developed after
    the gunshot wound. M rs. Blea stated that her husband began expressing suicidal
    thoughts w hile he was hospitalized after the gunshot incident, and continued to
    talk about suicide regularly thereafter. Aplt’s App. vol. I, at 332-33. She also
    testified about the physical limitations her husband faced as a result of his injury:
    since 1997, her husband had only rarely left the house with her and their son; he
    has not shopped, cooked, or cleaned since then; and he cannot sleep through the
    night.
    The A LJ’s written decision fails to mention any of the particulars of M rs.
    Blea’s testimony, and in fact, never even mentions the fact that she did testify
    regarding the nature and severity of her husband’s impairments. M r. Blea
    contends that the A LJ committed reversible error by failing to mention or discuss
    23
    his w ife’s testimony corroborating his account of the progression of his post-
    traumatic arthritis and depression. The Commissioner replies that the A LJ’s
    omissions are not reversible error because “the ALJ is not required to make a
    written finding about each witness’s credibility.” Aple’s Br. at 16 (citing Adams
    v. Chater, 
    93 F.3d 712
    , 715 (10th Cir. 1996)).
    The Commissioner is incorrect by only stating part of the rule in this
    circuit. In actuality, the ALJ is not required to make specific written findings of
    credibility only if “the written decision reflects that the ALJ considered the
    testimony.” Adam 
    s, 93 F.3d at 715
    . “[I]n addition to discussing the evidence
    supporting his decision, the ALJ also must discuss the uncontroverted evidence he
    chooses not to rely upon, as well as significantly probative evidence he rejects.”
    Clifton v. Chater, 
    79 F.3d 1007
    , 1009 (10th Cir. 1996).
    Here, the ALJ made no mention of M rs. Blea’s testimony, nor did he refer
    to the substance of her testimony anywhere in the written decision. Thus, it is not
    at all “clear that the ALJ considered [M rs. Blea’s] testimony in making his
    decision.” Adam 
    s, 93 F.3d at 715
    . Additionally, M rs. Blea’s testimony regarding
    her husband’s suicidal thoughts is not only uncontroverted; it serves to
    corroborate Dr. Padilla’s psychiatric examination of M r. Blea, where he stated
    that M r. Blea has been dysthymic for years. See Aplt’s App. at 243-46. Thus,
    the A LJ’s refusal to discuss why he rejected her testimony violates our court’s
    precedent, and requires remand for the ALJ to incorporate M rs. Blea’s testimony
    24
    into his decision. “W ithout the benefit of the ALJ’s findings supported by the
    weighing of this relevant evidence, we cannot determine whether his
    conclusion[s] . . . [are] supported by substantial evidence.” 
    Threet, 353 F.3d at 1190
    ; see also Baker v. Bowen, 
    886 F.2d 289
    , 291 (10th Cir. 1989) (“[W]here the
    record on appeal is unclear as to w hether the ALJ applied the appropriate standard
    by considering all the evidence before him, the proper remedy is reversal and
    remand.”).
    Additionally, M r. Blea contends that the failure to include discussion of
    M rs. Blea’s testimony contradicts two regulations: (1) SSR 83-20, which directs
    an ALJ to assess how lay evidence impacts the determination of an onset date;
    and (2) SSR 85-16, which relates only to mental impairments, and instructs that
    “relevant, reliable information, obtained from . . . family members . . . may be
    valuable in assessing” whether a mental impairment is disabling. SSR 85-16, at 4.
    The Commissioner argues that neither of these regulations is applicable to M r.
    Blea’s claim.
    W e agree with the Commissioner that neither of these regulations
    necessarily apply to M r. Blea’s claim before the ALJ, but caution that the ALJ
    should nevertheless be mindful of the regulations on remand. SSR 83-20 instructs
    an ALJ to consider “other sources of documentation” such as testimony from
    family when “reasonable inferences about the progression of the impairment
    cannot be made on the basis of the evidence in file and additional relevant
    25
    medical evidence is not available.” SSR 83-20, at 3. Depending upon the
    “reasonable inferences” that the ALJ makes in consultation with a medical
    advisor on remand, it may be necessary to consider M rs. Blea’s testimony
    pursuant to this provision of SSR 83-20.
    W ith regard to SSR 85-16, we similarly believe it is premature to address
    whether that regulation applies. SSR 85-16 concerns “the issues to be considered
    when an individual with a mental impairment requires an assessment of the
    residual functional capacity (RFC) in order to determine the individual’s capacity
    to engage in basic work-related activities.” SSR 85-16, at 1. W hether the ALJ
    will need to follow SSR 85-16 on remand depends upon whether the A LJ’s
    analysis of M r. Blea’s mental impairments reaches steps four or five of the five-
    step sequential analysis. See 
    id. at 2
    (explaining that an RFC assessment is
    unnecessary if an impairment is found to be of listing severity at step three
    because “[f]or impairments of listing severity, inability to perform substantial
    gainful activity (SGA) is presumed from prescribed findings.”).
    III. C ON CLU SIO N
    W e believe it is unclear when M r. Blea’s post-traumatic arthritis and
    dysthymia became disabling. Therefore, we reverse the m agistrate judge’s
    decision and direct that this case be remanded to the ALJ for further proceedings
    consistent with this opinion.
    26
