   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

      Upon receiving M atthews’ first application for benefits, the Social Security

Administration (“Administration”) determined M atthews was disabled by carpal

tunnel syndrome and awarded benefits in M ay 1996. In December 2000, the

Administration concluded M atthews was no longer disabled and terminated

benefits. M atthews did not appeal this decision. 1 On M arch 22, 2002, she filed

new applications for disability benefits. Although this new claim was also based

on carpal tunnel syndrome, M atthews identified a new disability onset date of

February 1, 2001. 2

      After conducting a hearing and receiving oral testimony from M atthews and

a vocational expert, the A LJ denied benefits. Although he found that M atthew s’

   In her reply brief, M atthews does not dispute the Administration’s assertion that
it terminated her prior disability benefits because it concluded her disability
ceased in December 2000. In her brief to the district court, M atthews conceded
that she previously “applied for Social Security disability insurance benefits and
was disabled until January 2001, when she was considered improved and her
benefits ceased.”
2
  Although M atthews initially identified a disability onset date of October 31,
1995, she amended her onset date to February 1, 2001 during a hearing before the
administrative law judge (“ALJ”). M atthews explained that she sought to amend
her onset date because the Administration had previously awarded and terminated
benefits in connection with her disability arising in 1995. As M atthews filed a
new application instead of appealing the termination of her prior benefits, she
wished to associate her new application with a disability onset date of February
2001. The ALJ permitted this amendment.

“bilateral carpal tunnel syndrome, status post injury to right wrist and obesity”

were severe impairments, the ALJ held that: (1) her allegations regarding her

limitations were “not totally credible”; (2) despite her severe impairments,

M atthews retained residual functional capacity to perform light work with a

limitation of “no constant use of the hands for such repetitive tasks as

keyboarding”; and (3) she retained residual functional capacity to perform her

past relevant work as a food assembler and receptionist.

      In December 2004, the Appeals Council denied M atthews’ request for

review of the A LJ’s decision. She then filed a complaint in the district court. In

June 2003 a magistrate judge, sitting by consent of the parties and by designation

of the district court, affirmed the denial of benefits. This appeal followed.

                                          II

      Because the Appeals Council denied review, the ALJ’s decision is the

Administration’s final decision for purposes of this appeal. See Doyal v.

Barnhart, 331 F.3d 758, 759 (10th Cir. 2003). In reviewing the ALJ’s decision,

“we neither reweigh the evidence nor substitute our judgment for that of the

agency.” Casias v. Sec’y of Health & Human Servs., 933 F.2d 799, 800

(10th Cir. 1991) (citation omitted). Instead, we review the decision only “to

determine whether the factual findings are supported by substantial evidence in

the record and whether the correct legal standards w ere applied.” D oyal,

331 F.3d at 760.

         In assessing whether M atthew s was disabled, the A LJ utilized the five-part

sequential evaluation process for disability determinations See 20 C.F.R.

§ 416.920; W illiams v. Bowen, 844 F.2d 748, 750-51 (10th Cir. 1988) (describing

five steps of disability evaluation process). M atthews argues the ALJ committed

reversible error in applying this process by: (1) failing to evaluate the opinion of

Dr. David W ong, one of her treating physicians; (2) failing to perform a proper

credibility determination; and (3) erroneously determining that M atthews could

perform her relevant past work. W e conclude each of these claims is without

merit.

                                            A

         M atthews first contends the ALJ erred in failing to address or assign weight

to evidence provided by Dr. W ong, her treating physician. Dr. W ong, an

orthopedic hand surgeon, treated M atthews from M ay 28, 1996 to February 13,

1997. In a February 1997 assessment, Dr. W ong concluded M atthews w as “still

symptomatic following four surgeries for [carpal tunnel syndrome]” and opined

that her work should be “no more strenuous than doing her normal activities of

daily living.” In particular, he stated, “Repetitive activities should be limited to a

total of four hours per day. She should do no lifting over ten pounds with either

hand.”

         Although the ALJ acknowledged M atthews’ prior surgeries and her

treatment history with Dr. W ong, his written decision did not explicitly analyze or

                                           -4-
reference Dr. W ong’s assessment. An ALJ has a duty to consider all evidence.

See Hamlin v. Barnhart, 365 F.3d 1208, 1223 n.15 (10th Cir. 2004). Failure to

consider significant evidence from a treating physician may constitute error in

most cases, see id.; however, we cannot conclude the ALJ erred in the instant

case. As noted above, the A dministration previously determined that M atthew s’

disability arose in 1995 and ceased in December 2000, and M atthews did not

appeal this determination. Instead, she filed a new application in 2002 and

identified a new disability onset date of February 2001. The A dministration’s

unchallenged determination that M atthews was no longer disabled as of December

2000 rendered Dr. W ong’s 1996 and 1997 assessments largely irrelevant.

M oreover, because M atthews identified an onset date of February 1, 2001 in her

current application, she was required to establish a new period of disability

arising on or after that date. Dr. W ong’s opinions in 1996 and 1997 do not

sufficiently aid her in this showing. W e accordingly reject M atthews’ argument

that the ALJ committed reversible error by failing to explicitly evaluate

Dr. W ong’s opinions.

                                          B

      M atthews also challenges the ALJ’s finding that her “allegations regarding

her limitations are not totally credible.” “Credibility determinations are peculiarly

the province of the finder of fact, and we will not upset such determinations when

supported by substantial evidence.” Diaz v. Sec’y of Health & Human Servs.,

                                         -5-
898 F.2d 774, 777 (10th Cir. 1990); see also W hite v. Barnhart, 287 F.3d 903, 910

(10th Cir. 2001) (stating that “ALJ’s credibility findings warrant particular

deference”).

       In making his adverse credibility determination, the ALJ relied on the lack

of supporting medical evidence and treatment for the time period after February

2001, explaining that:

       After giving due consideration to credibility, motivation, and the
       medical evidence, the Administrative Law Judge is persuaded that
       this claimant exaggerates [her] symptoms to include disabling pain.
       The claimant did not see a doctor from 1997 until she fractured her
       right wrist in January 2001. After being released by Dr. Hawkins on
       February 28, 2001 the record indicates that she has not sought
       medical treatment for her arm and hand complaints. The failure to
       seek or obtain medical attention is not consistent with a chronic or
       worsening medical condition. It is reasonable to assume she would
       exhaust every means possible to obtain relief if she was experiencing
       severe chronic pain. There are public facilities available to those
       who do not have insurance or who are unable to pay for medical care.

       W e agree with M atthews that certain aspects of the ALJ’s credibility

analysis appear to be boilerplate language and speculation. See Aplt. A pp.,

Vol. 2 at 20-21 (stating that plaintiff’s “allegedly limited daily activities cannot

be objectively verified with any reasonable degree of certainty,” and that “even if

claimant’s daily activities are truly as limited as alleged, it is difficult to attribute

that degree of limitation to the claimant’s medical condition, as opposed to other

reasons, in view of the relatively weak medical evidence and other factors”).

However, as both the ALJ and the magistrate judge noted, the record contains no



                                            -6-
medical evidence of carpal tunnel syndrome after February 2001. See W illiams,

844 F.2d at 751 n.2 (stating that social security claimant has burden of proof with

respect to a show ing of impairment). Nor is there any indication that M atthews

sought treatment for this condition after February 2001. 3 See Kepler v. Chater,

68 F.3d 387, 391 (10th Cir. 1995) (stating that factors to be considered by ALJ in

assessing credibility include extensiveness of attempts to obtain relief and

frequency of medical contacts). Given the lack of medical proof in the record, w e

conclude the ALJ’s adverse credibility finding was supported by substantial

evidence. 4

                                         C

      Finally, M atthews contends the ALJ erred in determining she retained the

residual functional capacity to perform her past relevant work. Parties do not


3
  M atthew s visited D r. Haw kins several times in 2001 to receive treatment for a
wrist fracture. Reports for these visits contain no mention of carpal tunnel
syndrome. An A pril 2002 report from another treating physician, Dr. Davis, also
fails to reference carpal tunnel. In January 2004, M atthews visited Dr. Davis to
receive treatment for acute sinus. The report from this visit contains a single
notation of carpal tunnel without further comm ent. This stray reference does not
suffice as evidence of treatment for carpal tunnel syndrome.
4
  In reaching this conclusion, we recognize M atthews’ assertion that she was
unable to seek additional medical treatment during the relevant period because
she was indigent. W e note, however, that her counsel informed the ALJ that
Dr. Davis had been requested to prepare an evaluation for M atthews. Although
the ALJ agreed to keep the administrative record open for 14 days to allow for
this submission, M atthews subsequently failed to submit an evaluation from
Dr. Davis. There is no indication in the record that this failure was due to her
indigency. In the absence of such a showing, we see no basis for disturbing the
ALJ’s adverse credibility determination.

dispute that M atthews’ past work as a food assembler and receptionist required

“frequent” use of the hands. Relying on the four-hour, repetitive hand-use

limitation imposed by Dr. W ong in February 1997, M atthews faults the

Administration for failing to explain how an individual with her limitations can

perform her past work. However, Dr. W ong’s 1997 repetitive-activity limitation

was nullified by the Administration’s December 2000 finding that M atthews was

no longer disabled. W e therefore reject M atthews’ argument that the ALJ erred in

failing to properly evaluate her ability to perform relevant past work. In addition

to the above-noted lack of evidence of carpal tunnel syndrome, no post-February

2001 medical evidence indicates that M atthews is incapable of using her hands

frequently during an eight-hour work day. Plaintiff carried the burden to proffer

such medical evidence, see W illiams, 844 F.2d at 751 n.2, and has failed to do so.
