    MICHAEL J. ASTRUE, Commissioner                             (N.D. Okla.)
    of the Social Security Administration,
    Defendant-Appellee.
    ORDER AND JUDGMENT *           0F
    Before HARTZ, ANDERSON, and EBEL, Circuit Judges.
    Gloria Borgsmiller appeals from an order of the district court affirming the
    Commissioner’s decision denying her application for disability benefits under the
    Social Security Act. We exercise jurisdiction under 
    28 U.S.C. § 1291
     and 
    42 U.S.C. § 405
    (g), and reverse and remand for further proceedings.
    *
    After examining the briefs and appellate record, this panel has determined
    unanimously to grant the parties’ request for a decision on the briefs without oral
    argument. See Fed. R. App. P. 34(f); 10th Cir. R. 34.1(G). The case is therefore
    ordered submitted without oral argument. This order and judgment is not binding
    precedent, except under the doctrines of law of the case, res judicata, and collateral
    estoppel. It may be cited, however, for its persuasive value consistent with
    Fed. R. App. P. 32.1 and 10th Cir. R. 32.1.
    I. Background
    In 1999, Ms. Borgsmiller had back surgery due to a herniated disc. Although
    the surgery was initially successful in relieving her back pain, she began to
    experience pain again a few years later. In November 2001, she was terminated from
    her employment as an office manager and has not engaged in substantial work since
    that time. She applied for disability benefits in September 2006, alleging disability
    beginning on November 30, 2001, due to a back injury, arthritis, hypothyroidism, and
    high blood pressure. She claimed that due to these conditions she could not sit,
    stand, or walk for any length of time and was bedridden for three to four weeks at a
    time.
    The facts of Ms. Borgsmiller’s medical history concerning her back pain are
    known to the parties and so we only summarize them here. 1 After her back surgery,
    1F
    Ms. Borgsmiller first sought treatment for back pain in 2002, complaining of pain in
    her back that radiated down her left leg. She was diagnosed with lower back pain
    with radiculopathy, to be treated with pain medication and a muscle relaxant. The
    medical evidence submitted does not document further treatment for back pain until
    2006.
    In March 2006, she presented to Timothy Sanford, D.O., who became her
    treating physician, and reported that she had “flares of [back] pain” and, when severe,
    1
    Because Ms. Borgsmiller does not claim error on appeal with respect to her
    other conditions for her alleged disability, i.e., arthritis, hypothyroidism, and high
    blood pressure, we focus, as she does, on her back pain.
    -2-
    she hurt for three to eight weeks and was bedbound. Admin. R. at 166. He assessed
    low back pain, a herniated lumbar disc, and lumbar radiculopathy, and prescribed
    pain medication and a muscle relaxant. She periodically treated with Dr. Sanford
    between 2006 and 2008, reporting intermittent flares of back pain that she claimed at
    times left her bedbound for weeks or months at a time. Treatment notes from 2006
    reflect that Dr. Sanford opined that Ms. Borgsmiller’s herniated disc and lumbar
    radiculopathy interfered with her activities of daily living. He further opined that she
    was unable to work due to periods of exacerbation of back pain which left her
    bedbound. Ms. Borgsmiller continued treatment with pain medication and muscle
    relaxants, prescribed by Dr. Sanford, but did not otherwise have other treatment for
    her back pain. 2 A consultative examination done in November 2006 confirmed that
    2F
    Ms. Borgsmiller suffered from low back pain, leg pain, had a limited range of motion
    of her spine, and ambulated with an unstable gait at a slow speed with the use of a
    cane. An agency physician reviewed Ms. Borgsmiller’s records and concluded she
    had a residual functional capacity (RFC) to perform light work. In March 2007, the
    evidence was again reviewed by the agency and her light RFC was affirmed.
    The Commissioner denied Ms. Borgsmiller’s application initially and on
    reconsideration. After a de novo hearing before an administrative law judge (ALJ),
    the ALJ issued her decision in August 2008, finding Ms. Borgsmiller not disabled at
    2
    Treatment notes reflect Dr. Sanford referred Ms. Borgsmiller to a neurologist
    and recommended she undergo an MRI to further examine her lumbar radiculopathy,
    but she declined due to cost issues and the lack of health insurance.

    step four of the controlling five-step sequential analysis. See Lax v. Astrue, 
    489 F.3d 1080
    , 1084 (10th Cir. 2007) (explaining five-step process for evaluating claims for
    disability benefits). 3 The ALJ confirmed that Ms. Borgsmiller had not worked during
    3F
    the period from her alleged onset of disability, November 30, 2001, through her date
    last insured, December 31, 2006. She found that Ms. Borgsmiller had a severe
    impairment: degenerative disc disease of the lumbar spine. But she held that this
    impairment did not meet or equal the listing for presumptive disability for disorders
    of the spine, 20 C.F.R. Pt. 404, Subpt. P, App. 1, § 1.04.
    According to the ALJ, this impairment left Ms. Borgsmiller with an RFC to
    perform sedentary work. Relying on the Dictionary of Occupational Titles (DOT)
    and associated inquiries to the vocational expert (VE) who testified at the hearing,
    the ALJ concluded that Ms. Borgsmiller could still perform her past work as a service
    office manager and thus was not disabled.
    Ms. Borgsmiller’s request for review was denied by the Appeals Council,
    making the ALJ’s decision the Commissioner’s final decision for purposes of judicial
    review. Krauser v. Astrue, 
    638 F.3d 1324
    , 1327 (10th Cir. 2011). She then filed an
    action in the district court and it affirmed the Commissioner’s denial of benefits.
    3
    Although not pertinent here, the agency recently revised its rules regarding the
    five-step sequential analysis such that an ALJ may proceed to step five if she
    determines that there is insufficient evidence about a claimant’s past relevant work to
    make a finding at step four of the analysis. See Expedited Vocational Assessment
    Under the Sequential Evaluation Process, 
    77 Fed. Reg. 43492
    -01 (July 25, 2012)
    (codified at 
    20 C.F.R. § 404.1520
    (h)).
    -4-
    Ms. Borgsmiller now appeals.
    II. Discussion
    “In reviewing the [Commissioner’s] decision, we neither reweigh the evidence
    nor substitute our judgment for that of the agency.” Branum v. Barnhart, 
    385 F.3d 1268
    , 1270 (10th Cir. 2004) (internal quotation marks omitted). Rather, “[w]e
    review the Commissioner’s decision to determine whether the factual findings are
    supported by substantial evidence in the record and whether the correct legal
    standards were applied.” Watkins v. Barnhart, 
    350 F.3d 1297
    , 1299 (10th Cir. 2003).
    “Substantial evidence is such relevant evidence as a reasonable mind might accept as
    adequate to support a conclusion. It requires more than a scintilla, but less than a
    preponderance.” Lax, 
    489 F.3d at 1084
     (citation omitted) (internal quotation marks
    omitted).
    Ms. Borgsmiller raises three challenges to the Commissioner’s decision: the
    ALJ (1) should have recontacted Ms. Borgsmiller’s treating physician to clarify the
    record regarding her flares of back pain; (2) erred in her credibility determination;
    and (3) did not perform a proper step-four analysis. She also asserts claims of error
    by the magistrate judge. “[W]e independently determine whether the ALJ’s decision
    is free from legal error and supported by substantial evidence.” Wall v. Astrue,
    
    561 F.3d 1048
    , 1052 (10th Cir. 2009) (internal quotation marks omitted). Therefore,
    although we have considered these arguments about the magistrate judge in the
    -5-
    context of evaluating her claims that the ALJ erred, we do not expressly address her
    claims of error by the magistrate judge.
    A. Recontacting the Treating Physician
    Based on the record before her, the ALJ gave “great weight to Dr. Sanford’s
    opinion that [Ms. Borgsmiller was] disabled during her flares” but concluded that her
    flares of pain “[did] not occur often enough to prevent her from engaging in
    substantial gainful activity.” Admin. R. at 16. On appeal, Ms. Borgsmiller
    challenges the evidentiary support for this conclusion, in light of the weight given to
    Dr. Sanford’s opinion, and argues that the ALJ should have recontacted Dr. Sanford
    because the frequency or number of flares in the record is unclear. Relatedly, she
    also claims the ALJ impermissibly inferred that Ms. Borgsmiller was not disabled
    between her flares.
    Ms. Borgsmiller bears the burden of proving her disability and must do so by
    furnishing medical and other evidence of the existence of her disability. See Branum,
    
    385 F.3d at 1271
    . On the other hand, the ALJ has a basic obligation to “ensur[e] that
    an adequate record is developed during the disability hearing consistent with the
    issues raised.” 
    Id.
     (internal quotation marks omitted). As applicable at the time that
    Ms. Borgsmiller’s claim for disability benefits was adjudicated, an ALJ was required
    to recontact a treating source when the evidence received from a treating source was
    deemed inadequate for the ALJ to determine whether a claimant was disabled.
    White v. Barnhart, 
    287 F.3d 903
    , 908 (10th Cir. 2001); see also Robinson v.
    -6-
    Barnhart, 
    366 F.3d 1078
    , 1084 (10th Cir. 2004) (noting ALJ’s duty to seek additional
    evidence or clarification from treating source when evidence contains conflict or
    ambiguity, does not contain all the necessary information, or does not appear to be
    based on medically acceptable clinical and laboratory diagnostic techniques). 4 The
    4F
    ALJ’s duty in that regard was not dependent on any further action by the claimant
    once the evidence was deemed inadequate. White, 287 F.3d at 908.
    Ms. Borgsmiller does not point to evidence that states or suggests that the ALJ
    deemed the evidence from Dr. Sanford inadequate or ambiguous, and we find none.
    But Ms. Borgsmiller suggests the evidence was, in fact, inadequate or ambiguous
    because “the record is unclear as to the number of [her] flares” and “[t]he frequency
    of [her] disabling flares is open to question.” Aplt. Br. at 16-17. Based on our
    review, it does not appear, however, that further contact with Dr. Sanford would have
    provided the ALJ more clarity. Other than one medical visit with Dr. Sanford in
    March 2006, Dr. Sanford did not otherwise diagnose a flare or examine
    Ms. Borgsmiller when a flare was occurring. Rather, Dr. Sanford’s medical notes
    reflect only Ms. Borgsmiller’s self-reporting of her flares and the duration of those
    flares.
    4
    Effective March 26, 2012, the regulations governing an ALJ’s “duty” to
    recontact a medical source have changed. Under the current regulations, in
    evaluating insufficient evidence to determine disability, an ALJ “may recontact [a]
    treating physician, psychologist, or other medical source” but may instead seek
    further evidence from another source, including the claimant herself. See 
    20 C.F.R. § 404
    .1520b.
    -7-
    Accordingly, if the number and/or frequency of Ms. Borgsmiller’s flares are
    unclear, Dr. Sanford is of no assistance in clarifying the matter. And
    Ms. Borgsmiller has not argued that there are existing reports that Dr. Sanford could
    have provided the ALJ that would have assisted her in ascertaining the basis for his
    opinions. See e.g., Branum, 
    385 F.3d at 1271-72
     (concluding that the ALJ
    satisfactorily developed the record when the claimant’s “counsel did not indicate or
    suggest to the ALJ that any medical records were missing from the administrative
    record, nor did counsel ask for the ALJ’s assistance in obtaining any additional
    medical records”). We conclude that the ALJ was not obligated to recontact
    Dr. Sanford to clarify any alleged ambiguity regarding the number and/or frequency
    of Ms. Borgsmiller’s flares.
    Ms. Borgsmiller also challenges the ALJ’s conclusion that “Dr. Sanford’s
    opining that claimant was disabled during the flares implies that she was not disabled
    between the flares.” Admin. R. at 16; see also Aplt. Br. at 16, 18. To the extent
    Ms. Borgsmiller contends the ALJ should have recontacted Dr. Sanford instead of
    inferring that Ms. Borgsmiller was not disabled in between flares, we disagree.
    Dr. Sanford’s opinion that Ms. Borgsmiller is unable to work during her flares of
    severe pain is not a medical opinion, 
    20 C.F.R. § 404.1527
    (e), but an opinion on the
    ultimate issue of disability, which is a matter reserved to the Commissioner. See
    Castellano v. Sec’y of Health & Human Servs., 
    26 F.3d 1027
    , 1029 (10th Cir. 1994).
    As such, the ALJ was not required to recontact Dr. Sanford on this ground either.
    -8-
    B. Credibility Determination
    Ms. Borgsmiller next challenges the ALJ’s credibility determination, with
    respect to her complaints of pain. “Credibility determinations are peculiarly the
    province of the finder of fact, and we will not upset such determinations when
    supported by substantial evidence.” Hackett v. Barnhart, 
    395 F.3d 1168
    ,
    1173 (10th Cir. 2005) (internal quotation marks omitted). “However, findings as to
    credibility should be closely and affirmatively linked to substantial evidence and not
    just a conclusion in the guise of findings.” 
    Id.
     (brackets omitted) (internal quotation
    marks omitted).
    “To be disabling, pain must be so severe, by itself or in conjunction with other
    impairments, as to preclude any substantial gainful employment.” Talley v. Sullivan,
    
    908 F.2d 585
    , 587 (10th Cir. 1990) (internal quotation marks omitted). In assessing a
    claimant’s complaints of disabling pain, an ALJ must consider both objective and
    subjective evidence. See Kepler v. Chater, 
    68 F.3d 387
    , 390 (10th Cir. 1995).
    Because they are subjective, a claimant’s statements regarding her pain “can be
    evaluated only on the basis of credibility.” Thompson v. Sullivan, 
    987 F.2d 1482
    ,
    1488-89 (10th Cir. 1993). As such, “[subjective] statements regarding the intensity
    and persistence of the pain must be consistent with the medical findings and signs.”
    Gossett v. Bowen, 
    862 F.2d 802
    , 806 (10th Cir. 1988).
    In evaluating the credibility of a claimant’s subjective statements regarding
    pain, an ALJ should consider an “individual’s daily activities;” the “location,
    -9-
    duration, frequency, and intensity of the individual’s pain;” the “dosage and
    effectiveness of medications taken to alleviate pain;” and “[a]ny other factors
    concerning the individual’s functional limitations and restrictions due to pain or other
    symptoms.” Hamlin v. Barnhart, 
    365 F.3d 1208
    , 1220 (10th Cir. 2004) (alteration in
    original); see also Thompson, 
    987 F.2d at 1489
     (listing other factors such as
    frequency of medical contacts).
    The ALJ determined Ms. Borgsmiller had a RFC at the sedentary level. In
    doing so, the ALJ “d[id] not discount all of [Ms. Borgsmiller’s] complaints” of pain,
    but found that her treating physicians “did not place any functional restrictions on her
    activities that would preclude sedentary work activity with the previously-mentioned
    restrictions.” Admin. R. at 14. After discussing portions of both the objective and
    subjective evidence, the ALJ concluded that Ms. Borgsmiller’s “statements
    concerning the intensity, persistence and limiting effects of [her] symptoms are not
    credible to the extent they are inconsistent with [her] residual functional capacity
    assessment.” Id. at 15-16.
    In reaching this credibility finding, the ALJ stated that Ms. Borgsmiller’s
    flares of pain were “episodic . . . [and] occurring with decreasing frequency.” Id.
    at 16. As support, she pointed to medical evidence indicating a reported flare in
    October 2007, one in February 2008, and none between February 2008 and the time
    of the hearing in July 2008. And she stated that Dr. Sanford’s opinion that
    Ms. Borgsmiller was disabled during a flare implied that she was not disabled
    - 10 -
    between the flares. She discounted Ms. Borgsmiller’s allegations of disabling pain
    from arthritis and carpal tunnel syndrome by pointing to medical evidence showing a
    grip strength rated 5/5, and observed that while Ms. Borgsmiller used a cane, none
    was prescribed by a physician. Finally, she stated that Ms. Borgsmiller remained
    able to do chores, wash dishes, and prepare meals.
    On appeal, Ms. Borgsmiller contends that her “claim for disability does not
    hinge on limitations with her hands . . . [or] on her use of a cane,” but, instead,
    “revolves around her pain, and the limiting effect of her flares.” Aplt. Br. at 21. She
    argues then that the ALJ’s credibility determination rested in large part on the
    decreasing frequency of Ms. Borgsmiller’s flares and her daily activities, neither of
    which substantially support a finding that Ms. Borgsmiller’s complaints are
    incredible.
    As a preliminary matter, because the ALJ credited Dr. Sanford’s opinion that
    Ms. Borgsmiller is unable to work during flares of severe pain, the ALJ consequently
    must have found credible Ms. Borgsmiller’s subjective statements concerning the
    intensity and limiting effects of the pain she experienced during a flare of severe
    pain. Accordingly, although the ALJ did not specify so in her decision, we construe
    her adverse credibility determination to correspond only with Ms. Borgsmiller’s
    subjective statements concerning pain that she experienced during periods of
    non-flare activity.
    - 11 -
    Reviewing the ALJ’s credibility determination in this manner, we are not
    convinced that the ALJ’s rejection of Ms. Borgsmiller’s complaints of pain was
    supported by substantial evidence. There are ample reports in the record of
    Ms. Borgsmiller’s pain and prescriptions for pain medication. See Hamlin, 
    365 F.3d at 1221-22
     (holding that evidence relied on by ALJ was insufficient to undermine
    pain allegations where medical records were “replete with [claimant’s] reports of
    pain and of prescriptions”). Yet, as Ms. Borgsmiller correctly asserts, the only
    justifications given by the ALJ to discount Ms. Borgsmiller’s complaints were the
    decreasing frequency of her flares and an alleged ability to perform daily activities.
    Implicit in the ALJ’s reliance on the alleged decreasing frequency of
    Ms. Borgsmiller’s flares is a determination that the periods of non-flare activity
    during which Ms. Borgsmiller could work were increasing to the point that the flares
    had no significant impact on her overall ability to work. But the relevant period
    within which to assess the disabling impact of Ms. Borgsmiller’s flares was before
    December 31, 2006, when Ms. Borgsmiller was last insured for benefits. That
    Ms. Borgsmiller’s flares in 2007 and 2008 may have been so infrequent as to have no
    substantial impact on her ability to work does not necessarily support an inference
    that their frequency before 2007 had a similarly insubstantial impact.
    Ms. Borgsmiller testified that in the beginning, she experienced flares two or
    three times a year, the longest of which lasted three months. She further testified that
    she had been able to do better in the last few years by staying at home and by not
    - 12 -
    walking down stairs or getting into or out of a car. The ALJ did not assess the impact
    of Ms. Borgsmiller’s flares before 2007 or evaluate the credibility of her allegations
    that she could not work due to her pain during that earlier period. 5 In this, the ALJ
    5F
    erred.
    In further support of her credibility determination, the ALJ relied on
    Ms. Borgsmiller’s ability on “good days” to do chores, wash dishes, and prepare
    meals. 6 Ms. Borgsmiller testified that she is able to do household chores
    6F
    “sometimes,” Admin. R. at 32, and clarified as follows:
    [t]here are days that I can get up and I can . . . feel better
    and I can do some things. There are other times where I’m
    either sitting in my recliner or I’m in bed and there are
    other times I do not get out of bed for weeks at a time.
    
    Id.
     She also testified that she is unable to drive a vehicle, and “sometimes” has
    difficulty getting dressed, showered, or even retrieving food from the refrigerator.
    Although the ALJ did not err in considering Ms. Borgsmiller’s activities of daily
    5
    Even if the decreasing frequency of Ms. Borgsmiller’s flares in 2007 and 2008
    justified a determination that she was not disabled at the time of the hearing (a matter
    we need not decide), it did not rule out the possibility that she was disabled for some
    period before 2007 and thus entitled to a closed period of benefits.
    6
    It appears that the ALJ equated Ms. Borgsmiller’s “good days” with non-flare
    days and “bad days” with flare days. Such an assessment is problematic, however,
    because Ms. Borgsmiller testified that she is in pain “most of the time,” Admin. R.
    at 28, and has leg pain “all the time,” id. at 31. Conceivably, Ms. Borgsmiller may
    experience pain even on “good days.” The question is how severe or limiting that
    pain may be to determine whether Ms. Borgsmiller may engage in substantial gainful
    activity. Accordingly, the ALJ’s assessment is not necessarily accurate.
    - 13 -
    living, she “may not rely on minimal daily activities as substantial evidence that a
    claimant does not suffer disabling pain.” Thompson, 
    987 F.2d at 1490
    . Indeed, the
    “sporadic performance [of household tasks or work] does not establish that a person
    is capable of engaging in substantial gainful activity.” 
    Id.
     (alteration in original)
    (internal quotation marks omitted).
    Accordingly, although the ALJ tied her credibility finding to some specific
    evidence in the record, Qualls v. Apfel, 
    206 F.3d 1368
    , 1372 (10th Cir. 2000), we
    conclude none of the evidence relied upon, neither the decreasing frequency of flares
    nor Ms. Borgsmiller’s alleged ability to do some daily activities, provides substantial
    evidence that Ms. Borgsmiller’s complaints of pain were incredible. 7 See Hamlin,
    7F
    
    365 F.3d at 1221-22
    . Therefore, we reverse and remand, directing the ALJ to
    properly evaluate the evidence with respect to Ms. Borgsmiller’s credibility. We
    express no opinion, however, as to the weight the Commissioner should give
    Ms. Borgsmiller’s complaints of pain.
    7
    In further support of her credibility determination, the ALJ also stated that
    “Dr. Sanford’s opining that the claimant was disabled during the flares implies that
    she was not disabled between the flares,” Admin. R. at 16. Even assuming,
    arguendo, that the record supports a determination that Ms. Borgsmiller can work
    during non-flare periods, as we discuss infra, the pertinent issue in determining
    whether Ms. Borgsmiller is disabled within the meaning of the Act is whether she can
    work on a regular and continuing basis. Accordingly, there must be substantial
    evidence that Ms. Borgsmiller can engage in substantial gainful activity on a regular
    and continuing basis despite her flares of severe pain during which, the ALJ
    acknowledged, she could not work.
    - 14 -
    C. Step Four Determination
    Lastly, Ms. Borgsmiller contends that the ALJ erred in her RFC determination
    at phase one of step four by failing to include any limitations from her flares in the
    RFC assessment and in the inquiries to the VE at the hearing. She also contends this
    improper RFC determination “corrupted [the ALJ’s] findings at the third phase”
    regarding Ms. Borgsmiller’s ability to perform her past relevant work (PRW). Aplt.
    Br. at 24. We agree.
    Step four of the sequential analysis . . . is comprised of
    three phases. In the first phase, the ALJ must evaluate a
    claimant’s physical and mental residual functional capacity
    (RFC), . . . and in the second phase, he must determine the
    physical and mental demands of the claimant’s past
    relevant work. . . . In the final phase, the ALJ determines
    whether the claimant has the ability to meet the job
    demands found in phase two despite the mental and/or
    physical limitations found in phase one. . . . At each of
    these phases, the ALJ must make specific findings.

    511 F.3d 1270
    , 1272 (10th Cir. 2008) (alterations in original)
    (citations omitted) (internal quotation marks omitted). Regarding the first phase, an
    ALJ should “assess the nature and extent of [the claimant’s] physical limitations and
    then determine [the claimant’s] residual functional capacity for work activity on a
    regular and continuing basis.” Winfrey v. Chater,

    The ALJ concluded Ms. Borgsmiller had the RFC to lift/carry ten pounds,
    stand/walk for two hours during an eight-hour workday, only occasionally stoop, and
    frequently climb, balance, kneel, crouch, and crawl. In reaching this conclusion, she
    stated that Ms. Borgsmiller’s “treating physicians did not place any functional
    restrictions on her activities that would preclude sedentary work activity with the
    previously-mentioned restrictions.” Admin. R. at 14.
    With respect to Ms. Borgsmiller’s flares of severe pain, the ALJ gave “great
    weight” to Dr. Sanford’s opinion that Ms. Borgsmiller is unable to work during her
    flares. Id. at 16. But the ALJ concluded, based on the medical records showing
    episodic reports of flares and decreasing flares, that Ms. Borgsmiller’s flares did not
    occur often enough to prevent her from engaging in substantial gainful activity. See
    
    20 C.F.R. § 404.1505
    (a) (noting that to be disabled, claimant must have impairment
    that lasts not less than twelve months and causes an inability to engage in any
    substantial gainful activity); see also Washington v. Shalala,

    In light of our determination regarding the ALJ’s credibility determination,
    because the ALJ’s credibility and RFC determinations are inherently intertwined, any
    new determination on credibility will necessarily require reassessment of
    Ms. Borgsmiller’s RFC. See Poppa v. Astrue, 
    569 F.3d 1167
    , 1171 (10th Cir. 2009).
    - 16 -
    substantial gainful activity requires determination that claimant can hold whatever
    job she finds for a significant period of time).
    On appeal, Ms. Borgsmiller first claims that the ALJ’s RFC assessment is
    improper because it did not include any limitations from her flares. We agree.
    Although Dr. Sanford’s opinion that Ms. Borgsmiller is “unable to work” during her
    flares of severe pain, Admin. R. at 158, is an opinion on the ultimate issue of
    disability, which is a matter reserved to the Commissioner, Castellano, 
    26 F.3d at 1029
    , the ALJ gave the opinion great weight and thus accepted that Ms. Borgsmiller
    cannot work during her flares of severe pain.
    But the ALJ omitted this limitation in her RFC assessment. As a result, the
    ALJ’s RFC assessment contradicts her own determination that Ms. Borgsmiller is
    unable to work during flares of severe pain. Further, while the ALJ stated in support
    of her RFC assessment that Ms. Borgsmiller’s treating physicians did not place any
    functional restrictions on her activities, this is accurate only with respect to those
    periods when Ms. Borgsmiller is not experiencing flares of severe pain. When she is
    experiencing flares of severe pain, Dr. Sanford opined that Ms. Borgsmiller is unable
    to work, which represents a significant functional restriction on her activities.
    Accordingly, the ALJ’s RFC does not accurately reflect Ms. Borgsmiller’s pain
    limitation, and, therefore, the ALJ erred at the first phase of the step four analysis.
    See, e.g., Winfrey, 
    92 F.3d at 1023-24
     (noting ALJ’s error in failing to include in
    RFC all the treating physician’s limitations that ALJ had credited).
    - 17 -
    Relatedly, we also find problematic the ALJ’s conclusion that “the flares do
    not occur often enough to prevent [Ms. Borgsmiller] from engaging in substantial
    gainful activity,” Admin. R. at 16. Ms. Borgsmiller testified that her flares last for
    weeks, even months, at a time. The ALJ relied on evidence that the flares were
    occurring with decreasing frequency in 2007 and 2008 to conclude that they did not
    interfere with Ms. Borgsmiller’s ability to engage in substantial gainful activity.
    But even if the frequency of the flares had declined in 2007 and 2008, that
    does not mean they were not disabling before 2007, when they occurred with more
    frequency. Whether Ms. Borgsmiller’s flares happened with such frequency, and
    were of such duration, as to prevent her from engaging in substantial gainful activity
    between the November 2001 onset date and December 31, 2006, when she was last
    insured for benefits, is a separate inquiry altogether. And it is one the ALJ did not
    specifically address. We recognize that the ALJ need not discuss every piece of
    evidence, Clifton v. Chater, 
    79 F.3d 1007
    , 1009-10 (10th Cir. 1996), and it is
    possible that she considered the flares that occurred prior to 2007, in concluding that
    they did not occur with sufficient frequency as to be disabling. But to the extent the
    ALJ considered only the frequency of the flares that occurred after December 31,
    2006, in reaching that conclusion, such consideration was erroneous.
    Ms. Borgsmiller also contends, and we agree, that the ALJ’s analysis at phase
    three of step four was flawed. Phase three requires the ALJ to determine whether the
    claimant has the ability to meet the job demands of the PRW found in phase two
    - 18 -
    despite the mental and/or physical limitations found in phase one. Bowman, 
    511 F.3d at 1272
    . As noted previously, the ALJ failed to include Ms. Borgsmiller’s pain
    limitation in the RFC assessment at phase one. She concluded, however, that
    Ms. Borgsmiller could perform her PRW as a service office manager. [Admin. R.
    at 16]. The ALJ’s finding regarding Ms. Borgsmiller’s ability to perform her PRW is
    not supported by substantial evidence because it does not accurately reflect the record
    or her own findings.
    In determining whether Ms. Borgsmiller is able to perform her PRW, the ALJ
    sought information from the VE about Ms. Borgsmiller’s PRW. See Winfrey, 
    92 F.3d at 1025
     (“[T]he ALJ may rely on information supplied by the VE at step four about
    the demands of the claimant’s [PRW].”). The VE testified that Ms. Borgsmiller’s
    PRW as a service office manager was most akin to a secretarial position, and
    constituted a sedentary job, and that her PRW as an apartment manager constituted a
    light job. Based on our review, the ALJ did not, however, adequately inquire about
    the demands of Ms. Borgsmiller’s PRW in order to determine whether she could meet
    those demands.
    Specifically, although the ALJ credited Dr. Sanford’s opinion that
    Ms. Borsmiller is unable to work during flares of severe pain, the record does not
    demonstrate that the ALJ sought information from the VE regarding whether the
    demands of Ms. Borgsmiller’s PRW permitted absence from work for periods of time
    of the length and frequency that the ALJ determined corresponded with
    - 19 -
    Ms. Borgsmiller’s flares of severe pain. This error may have resulted, in part, from
    the ALJ’s initial failure to make specific and adequate findings regarding the
    frequency and duration of Ms. Borgsmiller’s flares of severe pain before 2007. 9 9F
    Ms. Borgsmiller testified that there are “times [she] does not get out of bed for weeks
    at a time,” Admin. R. at 32; see also id. at 156, and she reported having been
    bedbound “for up to 3 months at a time,” id. at 162; see also id. at 36. Yet, there is
    no evidence in the record demonstrating the vocational impact of these periods of
    severe inactivity. Accordingly, the inadequacies of the ALJ’s inquiries to the VE
    rendered her determination that Ms. Borgsmiller could perform her PRW
    unsupportable.
    “In order to engage in [substantial] gainful activity, a person must be capable
    of performing on a reasonably regular basis.” Byron v. Heckler, 
    742 F.2d 1232
    , 1235
    (10th Cir. 1984). But without making necessary findings regarding the demands of
    Ms. Borgsmiller’s PRW in conjunction with Ms. Borgsmiller’s pain limitation, the
    ALJ could not, and did not, make an adequate finding regarding Ms. Borgsmiller’s
    ability to perform her PRW on a regular and continuing basis. See Washington,
    
    37 F.3d at 1442
     (determination that claimant is able to engage in substantial gainful

    In order to make the necessary findings on remand, it may be necessary for the
    ALJ to solicit more information from Ms. Borgsmiller concerning the frequency and
    duration of her flares between her alleged onset date and December 31, 2006.

    activity requires a determination that claimant can hold whatever job she finds for a
    significant period of time); Byron, 
    742 F.2d at 1235
    . As such, the ALJ’s conclusion
    that Ms. Borgsmiller may perform her PRW as a service office manager is not
    adequately supported in the record.
    We conclude the ALJ erred in her step four analysis by failing to include
    Ms. Borgsmiller’s pain limitation in the RFC assessment and in failing to make
    inquiries of the VE necessary to determine the vocational impact of
    Ms. Borgsmiller’s flares of severe pain. We, therefore, reverse and remand on this
    issue also.
