UNITED STATES COURT OF APPEALS

FOR THE TENTH CIRCUIT

BETTY J. GIRDNER,

Plaintiff-Appellant,

v.

KENNETH S. APFEL, Commissioner,

Social Security Administration,*

Defendant-Appellee.

No. 97-7055

(D.C. No. 96-CV-99-S)

(E.D. Okla.)

ORDER AND JUDGMENT**

Before BALDOCK, BARRETT, and MURPHY, Circuit Judges.

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
-2-

argument. See Fed. R. App. P. 34(f); 10th Cir. R. 34.1.9. The case is therefore

ordered submitted without oral argument.

Betty J. Girdner appeals from an order of the district court affirming the

Commissioner’s decision denying her application for social security disability

benefits. Ms. Girdner filed for disability benefits on June 30, 1993. The alleged

basis of her disability is major depression and bladder problems. Her application

was denied initially and on reconsideration.

Following a de novo hearing on June 21, 1994, an administrative law judge

(ALJ) determined that she was not disabled within the meaning of the Social

Security Act. Ms. Girdner thereafter filed a complaint in district court, which

affirmed the Commissioner’s decision. Ms. Girdner then appealed to this court.

We review the Commissioner’s decision to determine whether the factual

findings are supported by substantial evidence in the record viewed as a whole

and whether the correct legal standards were applied. See Andrade v. Secretary

of Health & Human Servs., 985 F.2d 1045, 1047 (10th Cir. 1993). Substantial

evidence is “such relevant evidence as a reasonable mind might accept as

adequate to support a conclusion.” Fowler v. Bowen, 876 F.2d 1451, 1453

(10th Cir. 1989) (quotation omitted).

The Commissioner has established a five-step evaluation process for

determining whether a claimant is disabled within the meaning of the Social
-3-

Security Act. See Williams v. Bowen, 844 F.2d 748, 750-52 (10th Cir. 1988)

(discussing five-step disability test). The claimant retains the burden of proving

disability throughout the first four steps of the process. See id. at 751.

Here, the ALJ determined, at step four, that Ms. Girdner retained sufficient

residual functional capacity (RFC) to allow her to return to her past relevant work

as a senior interviewer at an employment office. Ms. Girdner contends that this

determination is flawed in several respects.

Ms. Girdner contests the ALJ’s conclusion that her bladder problems

(which include both incontinence and urinary retention) have only a minimal

effect on her ability to work and are therefore not severe impairments. In

rejecting her claim of bladder problems, the ALJ relied on the lack of clinical

or diagnostic evidence to support the existence of a urological impairment

which would produce the symptoms to the degree Ms. Girdner indicated. 

See Appellant’s App., Vol. II at 15.

The ALJ acknowledged that Ms. Girdner had been evaluated by a urologist

for her bladder problems. However, he rejected this evaluation as evidence of

disability because the urologist’s records were not made part of the record. See

id. This was error. An ALJ cannot conclude that an impairment is non-severe

based on lack of medical evidence when he is aware that such evidence exists or

may exist but simply has not been made part of the record. He “has the duty to
-4-

develop the record by obtaining pertinent, available medical records which come

to his attention during the course of the hearing.” Carter v. Chater, 73 F.3d 1019,

1022 (10th Cir. 1996). The ALJ should have attempted to obtain and review the

urologist’s records before rejecting Ms. Girdner’s alleged impairment based on

lack of medical evidence. For this reason, we must reverse and remand for

further development of the record and reconsideration regarding this impairment.

On remand, the ALJ should also reconsider his analysis of Ms. Girdner’s

alleged mental impairment. The ALJ rejected her treating psychologist’s

conclusion that Ms. Girdner frequently decompensates under pressure; however,

he did not point to any objective evidence to support his own conclusion that such

episodes occurred only “once or twice” in work or work-like settings. See Cruse

v. United States Dep’t of Health & Human Servs., 49 F.3d 614, 617-18 (10th Cir.

1995) (ALJ must discuss evidence used to reach conclusions on psychiatric

review technique (PRT) form, and such conclusions must be supported by

substantial evidence).

Moreover, although he completed the PRT form, the ALJ failed to comply

with the remaining two steps in the mental RFC determination. See Winfrey v.

Chater, 92 F.3d 1017, 1023-26 (10th Cir. 1996) (describing three-step process

for evaluating impairments at step four). He did not make specific findings

concerning the mental demands of Ms. Girdner’s past relevant work, and he was
-5-

therefore unable to make appropriate findings about her ability to return to her

past relevant work despite her mental impairment.

The judgment of the United States District Court for the Eastern District of

Oklahoma is REVERSED, and this case is REMANDED for further proceedings

in accordance with this order and judgment.
