  •                             UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF COLUMBIA
    DEENA HARTLINE,
    Plaintiff,
    Civil Action No. 06-219 (CKK)
    v.
    MICHAEL J. ASTRUE, Commissioner of
    Social Security,
    Defendant.
    MEMORANDUM OPINION
    (March 31, 2009)
    Plaintiff Deena Hartline brings this action seeking review of Defendant’s final
    administrative decision denying her claim for Disability Insurance Benefits (“DIB”) and
    Supplemental Security Income Benefits (“SSIB”) pursuant to 
    42 U.S.C. § 405
    (g). Pending
    before the Court are Plaintiff’s Motion for Judgment of Reversal and Defendant’s Motion for
    Judgment of Affirmance. After reviewing the Parties’ briefs, the administrative record, and the
    relevant case law, the Court shall DENY [7] Plaintiff’s Motion for Judgment of Reversal and
    GRANT [10] Defendant’s Motion for Judgment of Affirmance, for the reasons that follow.1
    I. BACKGROUND
    A.        Legal Framework and Procedural History
    Plaintiff Deena Hartline petitioned the Social Security Administration for DIB and SSIB
    pursuant to Titles II and XVI of the Social Security Act on July 21, 1998. See Pl.’s Mot. at 1. To
    1
    Plaintiff’s Complaint named as the Defendant the then-Commissioner of Social
    Security, Jo Anne B. Barnhart. As Ms. Barnhart was sued in her official capacity, the Court has
    substituted the current Commissioner of Social Security, Michael J. Astrue, as the Defendant
    pursuant to Federal Rule of Civil Procedure 25(d).
    qualify for SSIB and DIB, a claimant must demonstrate an “inability to engage in any substantial
    gainful activity by reason of any medically determinable physical or mental impairment,”
    coupled with an inability to “engage in any other kind of substantial gainful work which exists in
    the national economy.” 
    42 U.S.C. § 423
    (d)(1)-(2); see 
    id.
     § 1382c(a)(3). By satisfying both
    conditions, a claimant is “disabled” for purposes of the Social Security Act. To decide whether a
    claimant has proven she is disabled, the ALJ must use a five-step sequential analysis. 
    20 C.F.R. §§ 404.1520
    , 416.920. The steps require a determination of (1) current work activity; (2)
    severity of the impairments; (3) whether the impairment meets or equals a listed impairment; (4)
    if the impairment prevents claimant from doing past work; (5) if the impairment prevents her
    from doing other work upon consideration of the claimant’s residual functional capacity
    (“RFC”). 
    Id.
    Plaintiff is a 41-year-old female resident of Washington, D.C. See Pl.’s Mot. at 2. A high
    school graduate who attended college for one year, Plaintiff worked as a dancer, waitress and
    office secretary for a cab company before her impairments allegedly rendered her unable to work
    from May 22, 1997, until January 2002. Id.; Administrative Record (“A.R.”) at 84, 351, 366-70.
    In her application for DIB and SSIB, Plaintiff alleged that her disabilities included low back pain,
    leg pain, depression, anxiety and bipolar disorder. See Pl.’s Mot. at 2; A.R. at 17.
    Plaintiff’s claims were initially denied. A.R. at 49, 53; see 
    id. at 33
     (“[y]our overall
    medical condition does cause some restrictions. However, there are still some types of work you
    can perform”); 
    id. at 35
     (“[w]e realize that your condition prevents you from doing the type of
    work that you have done in the past, but it does not prevent you from doing less demanding
    work”). Following this denial, Plaintiff requested a hearing before an Administrative Law Judge
    2
    (“ALJ”). 
    Id. at 56
    . That hearing occurred on August 8, 2000. 
    Id. at 347
    . In a decision dated
    November 22, 2000, the ALJ denied Plaintiff’s requested benefits. 
    Id. at 39-48
    . Plaintiff sought
    review of this decision by the Appeals Council. 
    Id. at 71
    . On March 26, 2004, the Appeals
    Council remanded the case to the ALJ with instructions to reevaluate Plaintiff’s claim in light of
    additional medical evidence and issue a new decision. 
    Id. at 77
     (“This evidence relates to the
    severity of the claimant’s affective disorder and lymphodema in her legs and may suggest
    severity greater than the Administrative Law Judge found. This evidence should be addressed
    and evaluated.”). Accordingly, a second hearing before the ALJ was held on October 13, 2004.
    
    Id. at 364
    . Plaintiff was represented by counsel, and Kathleen S. Sampeck, a vocational expert
    (“VE”), testified. 
    Id. at 364
    .
    On February 28, 2005, the ALJ issued a decision that again denied Plaintiff’s claim for
    benefits. A.R. at 16-24. At Step One, the ALJ noted that Plaintiff had been engaged in
    significant gainful activity since 2002.2 
    Id. at 17
    ; see 
    id. at 369
    ; Pl.’s Mot. at 2 n.1. At Step
    Two, he determined that the medical evidence established that Plaintiff suffered from “a ‘severe’
    physical impairment as a result of “lymphedema and degenerative joint disease” and a “‘severe’
    mental impairment at all times relevant to this decision.” A.R. at 18. At Step Three, the ALJ
    determined that Plaintiff’s impairments were not “manifested at a degree of severity which
    satisfie[d]” any of the Listings of Impairments at Appendix 1, Subpart P, No. 4 (20 C.F.R §
    404.1520(d)). A.R. at 18. With regard to Plaintiff’s physical condition, the ALJ found no
    2
    Pursuant to 
    20 C.F.R. §§ 404.1520
     and 416.920, the ALJ noted that “[i]f the claimaint is
    performing substantial gainful work, she is not disabled.” 
    Id. at 17
    . For reasons he did not
    articulate, however, the ALJ “elected to proceed with the five-step sequential evaluation.” 
    Id.
    The Court shall therefore address the same.

    evidence that showed “she is unable to effectively ambulate or perform fine and gross
    movements effectively as defined by Listings 1.02A/B” nor evidence of “documented nerve root
    compression, spinal arachnoiditis, or lumbar spinal stenosis to the degree required by Listing
    1.04.” 
    Id.
     In evaluating Plaintiff’s mental impairment, the ALJ found that “none of the
    functional limitation categories are manifested at a degree which satisfie[d]” Listings 12.04 or
    12.08. 
    Id.
     Specifically, the ALJ found that Plaintiff’s impairment resulted in no more than
    moderate limitation on her “activities of daily living,” “social functioning,” “concentration,
    persistence and pace,” and that no evidence showed a “deterioration or decompensation in work
    or work-like settings.” 
    Id. at 19
    .
    At Step Four, the ALJ found that Plaintiff’s past relevant work “would be precluded
    given her current level of restriction.” 
    Id. at 21
    . At Step Five, the ALJ determined, “based upon
    the claimant’s residual functional capacity, that “she is capable of performing a significant range
    of light work . . . .” 
    Id. at 22
    . See generally 
    20 C.F.R. §§ 404.1567
    , 416.967. Finding the VE’s
    testimony credible as to the availability of jobs that fit within the above limitations in the
    economy, the ALJ concluded that “[the claimant] is capable of making a successful adjustment to
    work that exists in significant numbers in the national economy. A finding of ‘not disabled’ is
    therefore reached within the framework of Medical-Vocational Rule 202.20.” A.R. at 23.
    Plaintiff sought review of this decision by the Appeals Council. 
    Id. at 12
    . On December 8, 2005,
    the Appeals Council upheld the decision of the ALJ, finding no basis for granting the request for
    review. 
    Id. at 7
    . Having exhausted her administrative remedies, Plaintiff has brought this action
    4
    seeking judicial review.3 Pl.’s Mot. at 1.
    B.      Evidence Contained in the Administrative Record
    The ALJ evaluated Plaintiff's condition based on evidence including various medical
    records (both physical and mental health records) and the testimony of Plaintiff and the VE
    during the administrative hearing in this case. The Court recounts below the most relevant
    portions of the administrative record.
    1.      Physical Health Records
    On July 23, 1997, Plaintiff began a series of hospital visits for her lower back pain. See
    A.R. at 145; 188. Plaintiff indicated during these visits that her back pain, which had been a
    recurring problem for the past several years, was triggered when she engaged in household
    chores such as washing the dishes and mopping the floor. 
    Id. at 188
    . While the examinations
    revealed “tenderness on either side of the spine,” the records indicated that Plaintiff was “[a]ble
    to bend forward & straighten.” 
    Id.
     On July 15, 1997, Plaintiff began a series of visits in
    connection with swelling and lesions on her legs and feet. 
    Id. at 173-86
    . Plaintiff was diagnosed
    3
    The Court notes that there is some inconsistency in the records as to whether Plaintiff
    seeks current disability benefits or benefits for a closed period of unemployment. According to
    the Complaint, “Plaintiff can no longer engage in her past relevant work or any other substantial
    gainful activity.” Pl.’s Compl. ¶ 5. Plaintiff, however, currently works full-time as a phone
    operator for a cab company, and has been employed in such capacity since January 2002. A.R. at
    367-69. Furthermore, at the most recent administrative hearing, counsel for the Plaintiff
    indicated that “this is a case for a closed period of disability benefits . . . when Claimant was
    unemployed.” A.R. at 385. Counsel further explained that “she is managing to do work,
    although somewhat accommodated” and that the work would probably qualify as substantial
    gainful employment “especially given the length of time she’s held her current employment.” 
    Id.
    The Court nevertheless need not resolve this discrepancy based on its resolution of the parties’
    motions.
    5
    with edema and cellulitis, and prescribed medication for these conditions.4 
    Id. at 144
    ; 173-186.
    Plaintiff continued receiving treatment and medication for these conditions through July 21,
    2000. 
    Id. at 301-34
    .
    A number of physicians examined Plaintiff and evaluated her medical history in
    connection with ongoing treatment and her disability claims. On August 4, 1998, Dr. Henry R.
    Herbert, M.D., an occupational medicine specialist, examined Plaintiff. 
    Id. at 143-45
    . Dr.
    Herbert noted that Plaintiff retained “complete range of motion of her lower extremities” and that
    the “[r]ange of motion of the back is compromised in that she can only bring her hands to the
    level of her knees.” 
    Id. at 144
    . Dr. Herbert indicated that Plaintiff “is not able to perform a job
    which would require extended periods of standing or walking, [though] she appears to be able to
    perform sedentary work with no lifting, pushing, pulling or carrying more than 10 lb.” 
    Id. at 143
    .
    On November 6, 1998, R.S. Kadian, M.D., a state agency physician, evaluated Plaintiff’s
    medical history to determine her physical residual function capacity (“RFC”). With regard to
    specific exertional limitations, Dr. Kadian determined that Plaintiff could occasionally lift 10
    pounds, frequently lift less than 10 pounds, stand or walk for at least 2 hours in an 8-hour
    workday, sit for a total of about 6 hours in an 8-hour workday and engage in an unlimited amount
    of pushing and pulling. A.R. at 220. In his report, Dr. Kadian reduced Plaintiff’s RFC to
    “sedentary” because of the pain in her legs and back and her inability to stand and walk for
    prolonged periods of time. A.R. at 225. Dr. Kadian indicated that “[n]o further reduction in
    RFC or finding of total disability is supported by objective medical findings.” 
    Id.
    4
    The record also indicates that the ALJ, as well as the Plaintiff’s psychiatrist, Dr. Mark
    Publicker, M.D., characterized the swelling in Plaintiff’s legs as “lymphedema.” 
    Id. at 18
    ; 144-
    47.
    6
    On July 7, 1999, Dr. Dev Chhabra, M.D., a state agency medical consultant, examined the
    Plaintiff and ordered an x-ray of her spine. 
    Id. at 217-18
    . Dr. Chhabra reported that the x-ray
    showed “mild DJD [degenerative joint disease] . . . and mild scoliosis.” 
    Id. at 217
    . Dr. Chhabra
    concluded that “the patient can sit, stand and walk with [a] normal gait, and has a history of
    bipolar disorder. The symptoms are under control with medication.” 
    Id. at 218
    .
    On May 9, 2000, Dr. Martin H. Stein, M.D., who was treating Plaintiff for her affective
    disorder, referred her to Kaiser Medical because of “at least 50-100 scratch induced scars on each
    leg . . . .and cellulitis on her left shin.” 
    Id. at 291
    . Dr. Stein also indicated that he was “treating
    her aggressively for her obsessive picking which may be the origin of her infection.” 
    Id. at 292
    .
    Plaintiff subsequently received antibiotics for the lesions on her legs, and, on May 12, 2000, and
    again on May 15, 2000, her doctor noted that Plaintiff’s condition was improving. See 
    id.
     at 308-
    9. On June 6, 2000, after a visit with Plaintiff, Dr. Stein reported that “[h]er legs are no longer
    erythematous. She remains in treatment with Kaiser . . . . She reports her picking on her skin has
    decreased.” 
    Id. at 293
    .
    2.      Mental Health Records
    The records indicate that several mental health specialists have evaluated Plaintiff during
    the period of alleged disability. See 
    id. at 139-72
    ; 198-215; 227-58; 269-95. Plaintiff visited Dr.
    Mark Publicker, M.D., a psychiatrist, at least once every six months from March 11, 1996, to
    February 11, 1999, and kept in “weekly telephone contact” with him during this time. 
    Id. at 232
    ;
    see 
    id. at 139-72
    . According to the records, one purpose of these visits was to evaluate how
    Plaintiff was responding to prescribed medications for anxiety and bipolar disorder. See 
    id. at 139-72
    . On October 22, 1998, Dr. Publicker reported that Plaintiff was “stable on klonapin for
    7
    panic,” “calm, . . . organized, unpressured, [with] no thought process disturbance.” 
    Id. at 142
    .
    During this evaluation, he also indicated that the Plaintiff’s Global Assessment of Function
    (“GAF”) was 75,5 the highest it had been during the past twelve months. A.R. at 142.
    On October 28, 1998, Dr. Carlos Hecker, M.D., a psychiatrist, evaluated the Plaintiff. 
    Id. at 198-201
    . Dr. Hecker reported that Plaintiff
    cried intermittently during the session . . . . She was fully oriented and had
    essentially an intact recent and remote memory. At times, it was difficult for her to
    concentrate and she appeared to be distracted. Her mood was distinctly sad and
    her affect responded accordingly. She had no psychotic process including
    hallucinations and delusions. Her insight was fair and her judgment was fair as
    well. Her intelligence appeared to be average. There were no unusual mannerisms
    of speech and behavior.
    
    Id. at 200
    . According to Dr. Hecker’s report, Plaintiff indicated that her “depression ha[d]
    improved greatly” because of medication prescribed over the past two years. 
    Id. at 198
    .
    Additionally, Dr. Hecker indicated that the Plaintiff’s Global Assessment of Function (“GAF”)
    was 50.6 A.R. at 200.
    On November 2, 1998, Taras J. Cerkevitch, Ph.D., a psychologist, evaluated Plaintiff’s
    file and completed a psychiatric review technique form. Id. at 202-215. Dr. Cerkevitch’s form
    indicates that Plaintiff’s mental impairments were severe, but that they were not severe enough to
    meet or equal a listed impairment. Id. at 209. Specifically, Dr. Cerkevitch’s report indicated that
    5
    A GAF rating between 71 and 80 reflects “no more than slight impairment in social,
    occupational or school funtioning.” Def.’s Mot. at 14 n.8 (citing Diagnostic and Statistical
    Manual of Mental Disorders, Fourth Ed., Am. Psych. Assoc., p. 32).
    6
    A GAF rating of 41 to 50 is assessed to reflect “serious symptoms (e.g., suicidal
    ideation, severe obsessional rituals, frequent shoplifting) or any severe impairment in social
    functioning (e.g., no friends, unable to keep a job).” Def.’s Mot. at 17 n.10 (citing Diagnostic
    and Statistical Manual of Mental Disorders, Fourth Ed., Am. Psych. Assoc., p. 32); Pl.’s Mot. at
    7 n.2.
    8
    Plaintiff: (1) experienced a “Slight” “Restriction of Activities of Daily Living,” (2) showed
    “Moderate” “Difficulties in Maintaining Social Functioning,” (3) “Often” exhibited
    “Deficiencies of Concentration, Persistence or Pace,” and (4) “Never” suffered from “Episodes
    of Deterioration or Decompensation in Work or Work-Like Settings.” Id. at 209. See generally
    20 C.F.R. Pt. 404, Subpt. P, App. 1, §§ 12.04, 12.08 (requiring a finding of “marked” difficulties
    or “repeated” episodes of deterioration before a disability determination). Accordingly, Dr.
    Cerkevitch conducted a mental RFC (“MRFC”) assessment based on Plaintiff’s affective and
    personality disorders. See A.R. at 202, 211. According to Dr. Cerkevitch’s MRFC assessment,
    Plaintiff was “Moderately Limited” in ten of the twenty listed mental activities, but “Markedly
    Limited” in none of the categories. Id. at 211-12. In summary, Dr. Cerkevitch reports that
    Plaintiff had “enough MFRC to understand, recall . . . & persist on simple tasks,” “can adapt . . .
    to most environments and can maintain social interaction in low demand environments. . . .” Id.
    at 213.
    On February 11, 1999, Dr. Publicker examined Plaintiff, and indicated in his progress
    notes that her bipolar disorder was “in remission” and that her GAF was 65.7 Id. at 139.
    Subsequently, Dr. Publicker filled out an evaluation, in the form of a checklist, regarding
    Plaintiff’s bipolar disorder, and characterized her condition differently than he had previously.
    See id. at 232-34. According to this checklist, Plaintiff’s condition resulted in a “[m]arked
    7
    A GAF rating between 61 and 70 indicates that a patient is suffering from “some mild
    symptoms (e.g., depressed mood and mild insomnia)” or “some difficulty in social, occupational
    or school functioning (e.g., occasional truancy, or theft within the household), but generally
    functioning pretty well and has some meaningful interpersonal relationships.” Def.’s Mot. at 14
    n.9 (citing Diagnostic and Statistical Manual of Mental Disorders, Fourth Ed., Am. Psych.
    Assoc., p. 32).

    restriction of daily living,” “[m]arked difficulties in maintaining social functioning,”
    “[d]eficiencies of concentration, persistence or pace” and “[r]epeated episodes of deterioration or
    decompensation in work or work-like settings.” Id. at 234. Dr. Publicker added that Plaintiff
    had an “[i]mpaired ability to maintain employment.” Id. In the comment section of the
    evaluation, Dr. Publicker remarked that Plaintiff has “has adhered to medication management.”
    Id.
    Similarly, on January 28, 2000, Plaintiff visited Dr. Stein, who subsequently filled out
    evaluations of Plaintiff’s mental status, her ability to do work-related activities, and her response
    to medications. Id. at 227-31; 285-87. Dr. Stein’s report shows that he examined Plaintiff every
    other week since November 2, 1999. Id. at 229. On the mental assessment checklist, Dr. Stein
    indicated that Plaintiff suffered from all but one of the thirteen listed symptoms.8 Additionally,
    Dr. Stein’s checklist indicates that these symptoms caused a marked restriction of activities of
    daily living, marked difficulties in maintaining social functioning, deficiencies of concentration,
    persistence or pace and repeated episodes of deterioration or decompensation in work or work-
    like settings. Id. at 231. Describing Plaintiff as a “[m]ultiproblem patient,” Dr. Stein’s diagnosis
    included, “[p]ost traumatic stress disorder, OCD, Depression, Migraine, [and] seizure disorder.”
    Id. at 229-31. Finally, Dr. Stein concluded, “[s]he is not employable.” Id. at 231 (emphasis in
    original). On a checklist designed to rate a patient’s ability to perform or adjust to work-related
    8
    Dr. Stein indicated that Plaintiff suffered from anhedonia, sleep disturbance,
    pyschomotor agitation or retardation, decreased energy, feelings of guilt or worthlessness,
    difficulty concentrating or thinking, thoughts of suicide, hallucinations, delusions or paranoid
    thinking, hyperactivity, pressure of speech, flight of ideas, easy distractibility, involvement in
    activities that have a high probability of painful consequences which are not recognized. Id. at
    229-230. Dr. Stein did not indicate whether or not Plaintiff suffered from appetite disturbance
    with change in weight. Id. at 229.
    10
    activities, Dr. Stein indicated the lowest possible level, “Poor/None” for each of the 15 listed
    abilities. Id. at 227-28. In response to the form’s request to “[d]escribe any limitations and
    include the medical/clinical findings that support the above assessments,” Dr. Stein responded
    that Plaintiff “[h]as post traumatic stress disorder, seizures and inability to screen out stress.” Id.
    at 228. With regard to Plaintiff’s response to medication, Dr. Stein’s report notes, “she is a bit
    more at ease with effexor and prozac. Others have noted she is doing better. She is less impulsive
    and less driven. She appreciates the change with the medication. She states she is scratching less
    than before and more aware of the scratching.” Id. at 285.
    3.      Transcript of the Administrative Hearings in This Case
    Plaintiff testified at two administrative hearings, once on August 8, 2000, and once on
    October 13, 2004. Id. at 347-86. At the first hearing, Plaintiff testified that she was a recovering
    heroin addict, currently enrolled in a methadone treatment program. Id. at 353-55. She indicated
    that she did not frequently leave her home, except to see her psychiatrist, attend twice-weekly
    Alcoholics Anonymous meetings and visit the methadone clinic. Id. Plaintiff testified that she
    walked with the aid of a cane, and that her neighbors assisted her with cooking, cleaning,
    shopping and transportation. Id. at 352. During the first hearing, the ALJ asked the VE if he
    could identify any jobs in the national economy that a hypothetical person who had the same age,
    education and work experience as the Plaintiff could perform. Id. at 358-59. Specifically, the
    ALJ asked the VE to consider someone who had “the capacity to do light work unskilled with
    limited general public contact.” Id. The VE testified that such a person could be employed as an
    inspector or a bindery worker helper. Id. at 359.
    At the second hearing, more than four years later, Plaintiff indicated that she was
    11
    currently employed full-time as a phone operator. Id. at 367. She testified that she cooked for
    herself, and that her roommate did the cleaning and shopping. Plaintiff indicated that she now
    attended Alcoholics Anonymous meetings three times a week. Id. at 367-69. Though she had no
    cane with her on the day of the hearing, Plaintiff indicated that she sometimes used a cane to help
    her walk. Id. at 369. Plaintiff testified that she had continued taking medication and receiving
    therapy for her pain and depression. Id. When asked if this had made a difference, she
    responded, “[i]t helps.” Id. at 369. Plaintiff testified that because of her back pain, she could
    only sit for one hour at her current job before having to get up and walk around. Id. at 371.
    When asked by counsel how her depression affects her, Plaintiff said, “[d]epression is crippling
    at times.” Id. at 372. When asked if she got along well with others, Plaintiff said, “[w]ell, I get
    along, because that’s survival to me. And I get along if it suits me to get along.” Id. at 376.
    During the hearing, the ALJ asked the VE if she could identify any jobs in the national
    economy that a hypothetical person who had the same age, education and work experience as the
    Plaintiff could perform. Id. at 381. Specifically, the ALJ asked the VE to consider someone who
    had “the capacity to perform light work unskilled with a sit, stand option.” Id. The VE testified
    that such a person could be employed as a router or dispatch clerk, office helper or non-postal
    mail clerk. Id.
    II. LEGAL STANDARD
    “In a disability proceeding, the ALJ ‘has the power and the duty to investigate fully all
    matters in issue, and to develop the comprehensive record required for a fair determination of
    disability.’” Simms v. Sullivan, 
    877 F.2d 1047

    HEW,

    , 281 (D.C. Cir. 1980)). The Social Security Act defines “disability” as an

    “inability to engage in any substantial gainful activity by reason of any medically determinable
    physical or mental impairment which can be expected to result in death or which has lasted or
    can be expected to last for a continuous period of not less than 12 months.” 
    42 U.S.C. § 423
    (d)(1)(A) (2004). Inability to engage in substantial gainful activity not only includes the
    individual’s inability to do his previous work, but requires as well an inability, “considering his
    age, education, and work experience, [to] engage in any other kind of substantial gainful work
    which exists in the national economy, regardless of whether such work exists in the immediate
    area in which he lives, or whether a specific job vacancy exists for him, or whether he would be
    hired if he applied for work.” 
    Id.
     at § 423(d)(2)(A). In making this determination, the ALJ is to
    consider (1) medical data and findings, (2) expert medical opinions, (3) subjective complaints,
    and (4) the plaintiff’s age, education, and work history; however, “[t]he expert opinions of a
    treating physician are binding on the fact finder unless contradicted by substantial evidence to the
    contrary.” Davis v. Heckler, 
    566 F. Supp. 1193
    , 1196 (D.D.C. 1983) (citing cases).
    A court will not disturb the determination of the Commissioner if it is based on
    substantial evidence in the record and the correct application of the relevant legal standards. 
    42 U.S.C. §§ 405
    (g), 1383(c); Butler v. Barnhart, 
    353 F.3d 992
    , 999 (D.C. Cir. 2004). Substantial
    evidence means “such relevant evidence as a reasonable mind might accept as adequate to
    support a conclusion.” Richardson v. Perales, 
    402 U.S. 389
    , 401 (1971) (citation omitted).
    While a scintilla of evidentiary support is insufficient, the test can be satisfied by “something less
    than a preponderance of the evidence.” Fla. Mun. Power Agency v. FERC, 
    315 F.3d 362
    , 365-66
    (D.C. Cir. 2003). In reviewing an administrative decision, a court may not determine the weight
    of the evidence, nor substitute its judgment for that of the Secretary if her decision is based on
    13
    substantial evidence. Butler, 
    353 F.3d at 999
    ; Hays v. Sullivan, 
    907 F.2d 1453
    , 1456 (4th Cir.
    1990). Instead, the reviewing court must carefully scrutinize the entire record to determine
    whether the Secretary, acting through the ALJ, has analyzed all the evidence and has sufficiently
    explained the weight he has given to obviously probative material. 
    Id.
     “Because the broad
    purposes of the Social Security Act require a liberal construction in favor of disability, the court
    must view the evidence in the light most favorable to the claimant.” Martin v. Apfel, 
    118 F. Supp. 2d 9
    , 13 (D.D.C. 2000) (citing Davis v. Shalala, 
    862 F. Supp. 1
    , 4 (D.D.C. 1994)).
    The reviewing court must also determine whether credible evidence was properly
    considered. 
    Id.
     (citing Dionne v. Heckler, 
    585 F. Supp. 1055
     (D.Me. 1984)). The ALJ’s final
    decision must contain “a statement of findings and conclusions, and the reasons or the basis
    therefor, on all material issues of fact, law, or discretion presented on the record.” 
    5 U.S.C. § 557
    (c). Importantly, an ALJ cannot merely disregard evidence which does not support his
    conclusion. Dionne, 
    585 F. Supp. at 1060
    . A reviewing court should not be left guessing as to
    how the ALJ evaluated probative material, and it is reversible error for an ALJ to fail in his
    written decision to explain sufficiently the weight he has given to certain probative items of
    evidence. Martin, 
    118 F. Supp. 2d at
    13 (citing Davis, 
    862 F. Supp. at 2
    ).
    III. DISCUSSION
    Plaintiff argues that the ALJ’s decision should be reversed, or in the alternative remanded
    to the Social Security Administration for a new hearing, and makes three arguments in support of
    these requests. First, she argues that the ALJ failed to properly evaluate Plaintiff’s RFC. See
    Pl.’s Mot. at 3-12. Second, she argues that the ALJ erred by posing a hypothetical question for
    the VE’s analysis that inaccurately characterized Plaintiff’s RFC. 
    Id. at 12-14
    . Finally, Plaintiff
    14
    argues that the ALJ failed to consider the opinion of Plaintiff’s treating physician. 
    Id. at 14-19
    .
    Defendant disputes Plaintiff’s characterization of the ALJ’s opinion, asserting that it was
    supported by substantial evidence. See generally Def.’s Mot.
    A.       The Residual Functional Capacity (“RFC”) Analysis
    To make a determination under steps Four and Five of the disability analysis, which
    involve an inquiry into the claimant’s ability to return to past work and a determination of
    whether future employment of any variety is possible, see 
    20 C.F.R. §§ 404.1520
    , 416.920, the
    ALJ must engage in a residual functional capacity (“RFC”) analysis. 
    20 C.F.R. §§ 404.1545
    ,
    416.945; SSR 96-8p, Policy Interpretation Ruling Titles II and XVI: Assessing Residual
    Functional Capacity in Initial Claims, 
    1996 WL 374184
     at *2 (S.S.A. July 2, 1996). An RFC is
    “an administrative assessment of the extent to which an individual’s medically determinable
    impairment(s), including any related symptoms, such as pain, may cause physical or mental
    limitations or restrictions that may affect his or her capacity to do work-related physical or
    mental activities.” SSR 96-8p, 
    1996 WL 374184
     at *2. The ALJ must explain how he
    considered and resolved ambiguities in the record with regard to the ultimate RFC decision.
    Butler, 
    353 F.3d at 1000
    .
    Plaintiff raises three main arguments challenging the ALJ’s RFC analysis. First, she
    argues that the ALJ was required to, but did not, perform a function-by-function assessment of
    Plaintiff’s ability to work, and include a narrative discussion of how the evidence supported the
    ALJ’s RFC conclusion. Pl.’s Mot. at 3-7. Second, she argues that the ALJ ignored evidence
    regarding the extent of Plaintiff’s mental impairments. Id. at 7-10. Finally, she argues that the
    ALJ failed to engage in a detailed assessment of Plaintiff’s capacity to perform the mental
    15
    demands of work. Id. at 10-12.
    The Court finds that the ALJ performed a sufficient function-by-function assessment of
    Plaintiff’s exertional and non-exertional abilities as well as sufficient narrative in support thereof.
    Plaintiff is correct that SSR 96-8p requires the ALJ to first assess a claimant’s “work-related
    abilities on a function-by-function basis” and instructs that “[o]nly after that may RFC be
    expressed in terms of exertional levels of work . . . .” SSR 96-8p, 
    1996 WL 374184
     at *1.9
    However, SSR 96-8p also provides “[w]hen there is no allegation of a physical or mental
    limitation or restriction of a specific functional capacity, and no information in the case record
    that there is such a limitation or restriction, the adjudicator must consider the individual to have
    no limitation or restriction with respect to that functional capacity.” 
    Id.
    The Court finds that the ALJ performed a sufficient function-by-function assessment of
    all functions for which the record included evidence of limitations. The ALJ’s conclusion
    regarding Plaintiff’s physical RFC stated:
    In setting the claimant’s residual functional capacity, the undersigned has also
    considered any medical opinions, which are statements from acceptable medical
    sources, which reflect judgments about the nature and severity of the impairments
    and resulting limitations . . . . No treating or examining physician has placed any
    permanent physical restrictions on the claimant . . . . While it is noted that the
    state agency medical experts below limited the claimant to sedentary exertion . . .,
    I am persuaded by the overall record that she retains the residual functional
    capacity for light work, lifting and/or carrying up to twenty pounds occasionally
    and ten pounds frequently. I do afford the claimant a sit/stand option with regard
    to her complaints of persistent back pain and difficulty with standing/walking due
    9
    SSR 96-8p specifically instructs the ALJ to consider the functions in paragraphs (b), (c),
    and (d) of 
    20 C.F.R. § 416.945
    , which include physical abilities (sitting, standing, walking,
    lifting, carrying, pushing, pulling, or other physical functions including manipulative or postural
    functions), mental abilities (understanding, remembering, carrying out instructions, responding
    appropriately to supervision, coworkers, and work pressures in a work setting), and other abilities
    affected by impairments (including specifically, impairments of vision). 
    20 C.F.R. § 416.945
    .
    16
    to the swelling in her legs. However, I do not find further physical limitation to
    be warranted given the opinion of Dr. Chhabra that the claimant can
    sit/stand/walk with normal gait . . . . Only “mild” joint disease and scoliosis is
    noted on the x-ray and neurological examination is non-focal. She has had very
    limited conservative treatment for pain complaints and has not undergone further
    evaluation or workup of her pain symptoms, such as physical therapy or pain
    management. She also reports that she returned to work three years ago.
    Medication appears to be effective in controlling her pain symptoms and she
    continues to work full time.
    A.R. at 21. Plaintiff contends that the ALJ failed to set forth any rationale as to how the evidence
    supports each of his conclusions. Pl.’s Mot. at 6-7. However, even a cursory glance at the
    passage above reveals that the ALJ considered Dr. Chhabra’s examination and Plaintiff’s return
    to her job when assessing Plaintiff’s ability to perform light work, and considered her swelling
    and back pain when affording her the sit/stand option.
    The ALJ’s opinion also considered Plaintiff’s mental impairments in analyzing her RFC.
    The ALJ’s opinion stated:
    With regard to her psychiatric symptoms, the record does not show continuing
    treatment since 2000 and she reports current effectiveness of psychotropic
    medication. She reports some continued problems dealing with past abuse issues,
    but subjectively notes that she gets along well with others. She reports problems
    with focus and in dealing with stress, but as noted, it appears that she is capable of
    fully carrying out her current job duties without significant difficulty. She is also
    capable of independently caring for her basic daily needs. While the state agency
    psychological expert [Dr. Cerkevitch] assessed numerous “moderate” limitations
    as noted in Exhibit 4F, I find that the claimant retains the residual mental capacity
    to carry out simple work-related tasks with limited general public contact. I reject
    the essentially “disabling” assessments contained in the record at Exhibits 7F, 8F,
    9F, as these assessments are not well-supported by objective findings and/or
    treatment records and appear to overly rely on the claimant’s subjective
    complaints.
    A.R. at 21. The ALJ also stressed that he did not fully credit the testimony concerning Plaintiff’s
    subjective complaints:
    17
    In reviewing the testimony I find the credibility of the claimant’s subjective
    complaints (and allegedly related functional limitations) to be only fair at best.
    While I accept that the claimant has limitations from her physical and mental
    condition, I do not accept that such limitations are of ‘disabling’ severity as
    alleged. As noted, the claimant reports that she is currently employed on a full
    time basis as a telephone operator . . . Per her reports, she remains capable of
    caring for her basic needs and notes effectiveness of medication in alleviating her
    physical pain symptoms and psychiatric symptoms as well. Apparently, her
    symptoms are adequately controlled with treatment/medication as evidenced by
    her ability to engage in full-time work. Accordingly, full credibility is not
    afforded to the claimant’s subjective statements, especially with regard to
    ‘disabling’ impairment, and I am persuaded that I have adequately accounted for
    the claimant’s limitations in . . . her residual functional capacity.
    A.R. 21.
    Based on the ALJ’s opinion, and particularly the passages quoted at length above, the
    Court finds that the ALJ identified inconsistencies in the record and explained how he arrived at
    his conclusions. The ALJ acknowledged the assessments of Dr. Stein and Dr. Publicker and the
    conclusion in these reports that Plaintiff was not employable, A.R. 239, and that she had an
    impaired ability to maintain employment, 
    id. at 234
    . Nevertheless, the ALJ found that these
    conclusions were not well-supported by the evidence (and testimony) in the record. And
    although Plaintiff asserts that the ALJ “provided no explanation or rationale for ignoring the[]
    limitations” contained within Dr. Cerkevitch’s report, a review of the ALJ’s opinion reveals
    otherwise. Pl.’s Mot. at 8. It is manifest that the ALJ considered these limitations, but situated
    them within the context of Plaintiff’s subsequent success with psychotropic medication and
    ability to return to work.
    Plaintiff next contends that the ALJ “ignored pertinent evidence” in conducting the RFC
    analysis, focusing on the reports of Dr. Cerkevitch and Dr. Heckler. Pl.’s Mot. at 7. With
    respect to Dr. Cerkevitch, Plaintiff simply paints an inaccurate picture of the ALJ’s reliance on
    18
    Dr. Cerkevitch’s assessment. Regarding the severity of Plaintiff’s limitations, Dr. Cerkevitch
    noted that Plaintiff “has enough MFRC to understand, recall . . . & persist on simple tasks . . .
    [and] can adapt . . . to most environments and can maintain social interaction in low demand
    environments . . . .” While Plaintiff argues that the ALJ ignored this assessment, it is clear from
    the ALJ’s findings that he expressly relied upon Dr. Cerkevitch’s assessment of Plaintiff’s
    limitations and incorporated them into his RFC assessment.
    With respect Dr. Heckler, Plaintiff asserts that the ALJ ignored Dr. Hecker’s diagnosis of
    dysthymic disorder, recurrent major depressive episodes, and assessment of Plaintiff’s GAF at
    50. While the ALJ did not specifically incorporate the findings of Dr. Hecker into his opinion, it
    is not apparent to the Court how the report of Dr. Hecker “clearly contradicted” the ALJ’s
    conclusions as Plaintiff asserts. Pl.’s Mot. at 9. Dr. Hecker’s report, like the other mental
    evaluations contained within the record, indicated that Plaintiff had severe mental impairments.
    But while Dr. Hecker’s report indicated that Plaintiff suffered from severe depression, it also
    noted that this depression “had improved greatly” with medication and treatment. A.R. at 198.
    This is entirely consistent with the ALJ’s finding that “the claimant has had ‘severe’ mental
    impairment at all times relevant to this decision,” but that “her symptoms are adequately
    controlled with treatment/medication . . . .” 
    Id. at 18, 21
    .10
    Plaintiff also argues that the ALJ failed to engage in the “more detailed” assessment of
    the Plaintiff’s mental limitations as required by SSR 96-8p. Pl.’s Mot. at 11; see SSR 96-8p,
    10
    Plaintiff quotes extensively from cases holding that contradictory medical evidence
    cannot be ignored by the ALJ. See Pl.’s Mot. at 8-9 (quoting Butler, 
    353 F.3d at 1002
    ; See v.
    Washington Metro. Transit Auth., 
    36 F.3d 375
    . 384 (4th Cir. 1994)). In this case, however, the
    Court finds that the ALJ’s RFC analysis thoroughly considered all probative evidence and
    resolved ambiguities or contradictions where they existed, rendering these cases inapposite.
    19
    
    1996 WL 374184
     at *2. Specifically, Plaintiff contends that the ALJ “cumulated [sic] the
    Plaintiff’s mental impairments into a less-detailed conclusion that the Plaintiff was limited to
    simple tasks with limited public contact.” Pl.’s Mot. at 11-12. Upon reviewing the ALJ’s
    opinion, the Court finds that the ALJ engaged in a sufficient assessment of the relevant evidence
    in the record. See A.R. at 19. In regard to Plaintiff’s activities of daily living, the ALJ noted,
    “[s]he is also capable of independently caring for her basic daily needs.” With respect to
    Plaintiff’s social functioning, the ALJ pointed out that Plaintiff “subjectively notes that she gets
    along well with others.” With respect to her concentration, persistence and pace, the ALJ noted
    that it “appears that she is capable of fully carrying out her current job duties without significant
    difficulty.”
    Plaintiff is correct that the ALJ did not specifically list the work-related functions
    itemized on Dr. Cerkevitch’s Mental Residual Functional Capacity Assessment. See A.R. at
    211-12. Plaintiff does not, however, cite any case supporting the supposition that an ALJ’s
    opinion must include such an itemization. The ALJ specifically incorporated Dr. Cerkevitch’s
    mental RFC assessment in his opinion. 
    Id. at 21
     (“[T]he state agency psychological expert
    assessed numerous “moderate” limitations.”). The Court notes that none of Plaintiff’s functions
    in Dr. Cerkevitch’s assessment were deemed “markedly limited.” 
    Id. at 211-12
    . Furthermore,
    given Plaintiff’s return to full-time employment subsequent to Dr. Cerkevitch’s evaluation, the
    ALJ was justified in not performing an itemized evaluation of Plaintiff’s work-related abilities.
    Her ability to perform work-related tasks was made evident to the ALJ from her ability to
    maintain a job for approximately three years.
    20
    B.       The ALJ’s Hypothetical Question to the Vocational Expert
    The Commissioner bears the burden under Step Five of the disability analysis to show
    that there are other jobs available in the national economy that can be performed by an individual
    with the claimant’s impairments. Brown v. Bowen, 
    794 F.2d 703
    , 706 (D.C. Cir. 1986) (citing 
    20 C.F.R. §§ 404.1520
    (f), 416.920(f)). In this case, the ALJ relied in part on the testimony of the
    VE, which the ALJ found to be credible. A.R. at 22. Plaintiff now disputes the substance of the
    hypothetical question posed by the ALJ:
    Assume a hypothetical person who has the same age, education, and work
    experience as the [Plaintiff], and who has the capacity to perform light work
    unskilled with a sit/stand option. Can you identify any jobs that such a
    hypothetical person can perform on a sustained basis and which jobs exist in
    significant numbers in the national economy?
    A.R. 381. Plaintiff argues that this question failed to incorporate the restrictions and limitations
    identified by Dr. Hecker and Dr. Cerkevitch in two ways: (1) the question did not expressly
    incorporate Plaintiff’s “need for limited general public contact” and (2) the question did not
    incorporate a “limitation to simple work-related tasks.” Pl.’s Mot. at 12-14. The Court finds
    neither argument to be meritorious.
    Plaintiff’s first argument fails because–as Defendant explains and Plaintiff does not
    dispute–the jobs listed by the VE (router, office helper, and non-postal mail clerk) do not require
    significant public contact. See Def.’s Mot. at 11 (relying on the Dictionary of Occupational
    Titles published by the Department of Labor). Thus, it appears that the VE may have
    incorporated this limitation into her response based on her observations at the administrative
    hearing, A.R. 381 (“[t]he record will reflect that this VE has been present the entire proceedings
    today”), and her review of the Plaintiff’s administrative folder, 
    id.
     (“Q: Did you review the
    21
    [Plaintiff’s] exhibit folder prior to this hearing? A: Yes.”). Equally problematic for Plaintiff’s
    argument is that there is also substantial evidence in the record that supports the ALJ’s
    determination not to include a specific reference to this limitation in his hypothetical. Most
    notably, Plaintiff conceded that she had been employed as a phone operator since 2002, which
    the ALJ noted “would involve dealing with individuals over the phone.” A.R. at 19. Plaintiff
    also testified that she gets along with others, 
    id. at 376
    , and a report from the director of her
    psychotherapy group noted that “she has also become an asset to other members of the group,
    through support and positive feedback.” 
    Id. at 327
    .11 Plaintiff’s second argument concerning the
    ALJ’s omission of “simple work-related tasks” from his hypothetical question is even farther
    afield because the ALJ’s hypothetical did incorporate the need for a job requiring only simple
    tasks when he asked the VE to consider only “light work unskilled.” See Def.’s Mot. at 12.
    Plaintiff does not argue that the jobs listed by the VE in response to the ALJ’s hypothetical
    question require more than simple work-related tasks. Accordingly, the Court finds that the
    ALJ’s hypothetical accurately described Plaintiff’s condition and that the ALJ properly relied
    upon the VE’s response regarding the availability of jobs available in the national economy.12
    11
    Plaintiff’s argument is also unpersuasive because the ALJ expressly incorporated the
    “limited general public contact” limitation into his hypothetical during Plaintiff’s first
    administrative hearing, and the VE’s response indicated that there were jobs that existed in
    significant numbers in the national economy despite a limited general public contact restriction.
    A.R. at 358-59.
    12
    The Court notes that Plaintiff cites several cases that stand for the proposition that a
    “response to a fatally defective question cannot constitute substantial evidence.” Pl.’s Mot. at 12-
    13. Plaintiff fails to draw any factual comparisons to these cases, or to otherwise indicate how
    they might be of use to the Court in the present case. Because the Court finds substantial
    evidence that the ALJ’s hypothetical accurately reflected Plaintiff’s impairments, the Court finds
    the cases cited by Plaintiff to be inapposite.
    22
    C.       Weight of Medical Opinions
    Plaintiff argues that the ALJ erred in failing to accord controlling weight, or any
    consideration whatsoever, to the opinions of Plaintiff’s treating physicians. See Pl.’s Mot. at 14-
    15. Defendants argue that the opinions of treating physicians were thoroughly considered, but
    that those conclusions unsupported by objective medical findings were properly accorded less
    than controlling weight. See Def.’s Mot. at 13-17.
    Plaintiff’s argument that the medical opinions of Dr. Stein and Dr. Publicker were
    ignored is without merit. The ALJ considered and explicitly rejected the “essentially ‘disabling’
    assessments contained in the record at Exhibits 7F, 8F, 9F, as these assessments [were] not well-
    supported by objective findings and/or treatment records and appear[ed] to overly rely on the
    claimant’s subjective complaints.” A.R. at 21. Although Plaintiff is correct that this circuit has
    adopted a “treating physician” rule whereby the “reports of treating physicians must be accorded
    substantial weight,” where, as here, a treating physician’s opinion is contradicted by substantial
    evidence, it is not binding on the ALJ. Williams v. Shalala, 
    997 F.2d 1494
    , 1498 (D.C. Cir.
    1993). In the present case, there are inconsistencies between the objective medical findings and
    Dr. Stein and Dr. Publicker’s conclusions that Plaintiff was unable to work.13 Def.’s Mot. at 13-
    14. Furthermore, as Defendant correctly points out, the conclusions rejected by the ALJ were not
    medical opinions, but conclusions regarding Plaintiff’s ability or inability to work. According to
    Social Security Agency regulations, “[a] statement by a medical source that you are ‘disabled’ or
    13
    For example, Dr. Publicker’s report of February 11, 1999 indicates that Plaintiff’s
    bipolar disorder was “in remission” and that she had “no thought process disturbance.” A.R. at
    139. These medical observations do not support Dr. Publicker’s subsequent report that Plaintiff
    had an “[i]mpaired ability to maintain employment.” Id. at 234.
    23
    ‘unable to work’ does not mean that we will determine that you are disabled.” 
    20 C.F.R. §§ 404.1527
    (e)(1), 4165.927(e)(1).
    Regarding the medical opinions of Dr. Stein, Dr. Publicker and other doctors, Plaintiff
    cites no specific mental impairments that the ALJ failed to consider or weigh. Instead, Plaintiff
    argues generally that “[e]ach . . . physician[] determined that the Plaintiff’s mental impairment
    was more limiting than the Administrative Law Judge found.” Pl.’s Mot. at 15. There is
    substantial evidence in the record, most notably from Dr. Stein and Dr. Publicker, to support the
    ALJ’s determination that Plaintiff was adequately controlling her symptoms with the help of
    medication. See A.R. at 142 (characterizing Plaintiff as “stable on klonapin for panic”), 
    id. at 285
     (“[S]he is a bit more at ease with effexor and prozac. Others have noted she is doing better.
    She is less impulsive and less driven. She appreciates the change with the medication.”). At
    bottom, the ALJ acknowledged all of the medical opinions in the record, explained why he
    viewed certain evidence as more credible than other evidence, and adequately explained why he
    did not give “controlling weight” to the essentially “disabling” assessments of Dr. Stein and Dr.
    Publicker.
    Finally, Plaintiff argues that “controlling weight” must be given to treating physicians
    under SSR 96-2p. Plaintiff fails, however, to establish that the opinions of Dr. Stein and Dr.
    Publicker qualify for consideration under this provision. According to SSR 96-2p, which
    Plaintiff quotes, “[i]t is an error to give an opinion controlling weight simply because it is the
    opinion of a treating source if it is not well-supported by medically acceptable clinical and
    laboratory diagnostic techniques or if it is inconsistent with the other substantial evidence in the
    case record.” SSR 96-2p 
    1996 WL 374188
     *2. Because the ALJ found that the opinions of Dr.
    24
    Stein and Dr. Publicker were not “well-supported by objective findings and/or treatment records
    and appear[ed] to overly rely on the claimant’s subjective complaints,” he was justified in
    according them less weight in his analysis.
    IV: CONCLUSION
    Based on the foregoing review of the relevant law and the administrative record, the
    Court finds that the Administrative Law Judge applied the correct legal standards and relied on
