KILOLO KIJAKAZI, Acting Commissioner
of Social Security,
Defendant-Appellee.
Appeal from the United States District Court
for the District of Oregon
Anna J. Brown, District Judge, Presiding
Submitted February 21, 2023**
Before: D. NELSON, SILVERMAN, and GRABER, Circuit Judges.
Susan V. Zimmerman appeals pro se the district court’s affirmance of the
Commissioner of Social Security’s denial of her application for disability
insurance benefits under Title II of the Social Security Act. We have jurisdiction

under 28 U.S.C. § 1291 and 42 U.S.C. § 405(g). We review de novo, Attmore v.
Colvin, 827 F.3d 872, 875 (9th Cir. 2016), and we affirm.
The Administrative Law Judge (“ALJ”) provided specific clear and
convincing reasons to discount Zimmerman’s symptom testimony by citing to
significant gaps in Zimmerman’s treatment, Zimmerman’s failure to follow
through with treatment recommendations, and inconsistencies between the
objective medical evidence and the limitations alleged. See Fair v. Bowen, 885
F.2d 597, 603 (9th Cir. 1989) (finding “unexplained, or inadequately explained,
failure to seek treatment” can constitute a clear and convincing reason for
discounting a claimant’s credibility regarding their symptoms); Regennitter v.
Comm’r of Soc. Sec. Admin., 166 F.3d 1294, 1297 (9th Cir. 1999) (holding that
inconsistency with objective evidence is a clear and convincing reason to discredit
a claimant’s testimony); Burch v. Barnhart, 400 F.3d 676, 679 (9th Cir. 2005)
(“Where evidence is susceptible to more than one rational interpretation, it is the
ALJ’s conclusion that must be upheld.”).
The ALJ properly discounted Dr. Crone’s medical opinion that Zimmerman
was incapable of work based on Zimmerman’s limited treatment prior to the
opinion and the lack of supporting medical evidence in the record. See Coleman v.
Saul, 979 F.3d 751, 757 (9th Cir. 2020) (determining that the ALJ provided
specific and legitimate reasons to discount opinions of claimant’s treating
2
physicians as the alleged severe limitations were unsupported by the record);
Chaudhry v. Astrue, 688 F.3d 661, 671 (9th Cir. 2012) (“The ALJ need not accept
the opinion of any physician, including a treating physician, if that opinion is brief,
conclusory, and inadequately supported by clinical findings.”) (internal quotation
marks omitted).
Contrary to Zimmerman’s contention, because the record was neither
ambiguous nor inadequate, no medical expert was needed to determine an onset
date of disability. See Mayes v. Massanari, 276 F.3d 453, 459–60 (9th Cir. 2001);
SSR 18-01p. Zimmerman’s argument that the ALJ erred in not considering the
additional evidence before the Appeals Council is unpersuasive.
Before the district court, Zimmerman failed to raise some of the issues she
raises here: whether the ALJ erred in evaluating Dr. Jones’ opinion; whether the
ALJ erred in addressing the third-party statement; whether the ALJ erred by failing
to order a consultative examination; and whether the ALJ properly considered
Zimmerman’s impairments of chronic fatigue syndrome and fibromyalgia in
assessing her residual functional capacity and in posing the hypothetical question
to the vocational expert. Zimmerman, therefore, has forfeited or waived these
arguments. See Greger v. Barnhart, 464 F.3d 968, 973 (9th Cir. 2006) (holding
that this court will generally not consider an issue raised for the first time on
appeal).
