MEMORANDUM*
LELAND DUDEK, Acting Commissioner
of Social Security,
Defendant - Appellee.
Appeal from the United States District Court
for the District of Montana
John T. Johnston, Magistrate Judge, Presiding
Argued and Submitted April 8, 2025
San Francisco, California
Before: SCHROEDER, PAEZ, and MILLER, Circuit Judges.
Karla Kay Gageby (“Gageby”) appeals the district court’s judgment
affirming 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. We reverse and remand.

This disposition is not appropriate for publication and is not precedent
except as provided by Ninth Circuit Rule 36-3.
1. Gageby argues that the Administrative Law Judge (“ALJ”) erred in
downgrading her limitations in maintaining concentration, persistence, and pace
from “moderate” to “mild” after a remand order from the district court.1 We agree.
The ALJ used nearly identical explanations to reach two different decisions. The
ALJ did not explain why the justifications for her prior decision following the
Psychiatric Review Technique, see 20 C.F.R. § 404.1520a, were no longer
persuasive or how the new evidence introduced or considered for the first time on
remand could justify downgrading Gageby’s limitations. Nor does the district
court’s remand decision explain the change: the district court held that substantial
evidence supported the ALJ’s initial finding, and it remanded solely for the ALJ to
evaluate Dr. Campion’s opinion for the first time.
ALJs must explain their decisions, including changes in findings. See
Treichler v. Comm’r of Soc. Sec. Admin., 775 F.3d 1090, 1102 (9th Cir. 2014)
(“Because the ‘grounds upon which an administrative order must be judged are
those upon which the record discloses that its action was based,’ the agency must
explain its reasoning.” (cleaned up) (quoting S.E.C. v. Chenery Corp., 318 U.S. 80,
87 (1943))); see also Motor Vehicle Mfrs. Ass’n of U.S., Inc. v. State Farm Mut.

The issue was “raised sufficiently for the [district] court to rule on it” and
therefore has not been forfeited. Cornhusker Cas. Ins. Co. v. Kachman, 553 F.3d
1187, 1191–92 (9th Cir. 2009) (quoting In re E.R. Fegert, Inc., 887 F.2d 955, 957
(9th Cir. 1989)).

Auto. Ins. Co., 463 U.S. 29, 42 (1983) (requiring “an agency changing its course”
to “supply reasoned analysis for the change”). The ALJ’s failure to explain why it
changed Gageby’s concentration limitations on remand is therefore legal error.
The ALJ’s error was not harmless, and remand to the agency is required.
“Moderate” limitations in concentration, persistence, and pace could affect
Gageby’s residual functional capacity (“RFC”), which presently contemplates that
Gageby can “maintain attention, concentration, persistence, and pace” for “8-hour
workdays and 40-hour workweeks.” The ALJ’s error also affected her assessment
of Dr. Campion’s medical opinion. In assigning weight to a medical opinion, the
ALJ was required to consider how “consistent a medical opinion is with the record
as a whole.” 20 C.F.R. § 404.1527(c)(4).2 Dr. Campion opined, among other
limitations, that Gageby had “moderate” limitations in maintaining concentration,
persistence, and pace. In assigning Dr. Campion’s opinion minimal weight, the
ALJ reasoned that “moderate limitations are not supported by the record as a
whole.” But in 2018, the ALJ found that the record supported finding moderate
limitations. Therefore, the ALJ’s evaluation of Dr. Campion’s medical opinion
appears to rely at least in part on her error in changing without justification
Gageby’s limitations in maintaining concentration, persistence, and pace. As a

result, the ALJ never grappled with the other limitations that Dr. Campion
identified, including his finding that Gageby was “moderately limited” in her
“ability to understand and remember detailed instructions” and in her “ability to
complete a normal workday and workweek without interruptions.” Because these
limitations could have affected her ultimate disability determination, the error is
not harmless. See Marsh v. Colvin, 792 F.3d 1170, 1173 (9th Cir. 2015). We
therefore remand to the agency for further proceedings.
2. Because the ALJ must reevaluate Dr. Campion’s medical opinion in any
case, we need not address Gageby’s other arguments that the ALJ erred in
evaluating his medical opinion.
REVERSED AND REMANDED.
