Appeal from the United States District Court

for the Northern District of Alabama

(July 23, 2015)

Before MARTIN, JORDAN, and ANDERSON, Circuit Judges.

PER CURIAM:

Derrick McCormick appeals the district court’s order affirming the 

Commissioner’s denial of his application for disability insurance benefits and

supplemental security income. After the Appeals Council for the Social Security 

Administration denied Mr. McCormick’s request for review, the district court 

affirmed the Administrative Law Judge’s decision. 

Mr. McCormick argues that the ALJ failed to consider the combination of 

his impairments as required by 20 C.F.R. § 416.920(a)(4)(ii), and that this alleged 

error is not harmless. Mr. McCormick also asserts that the ALJ’s determination—

that he could perform his past work duties—was not supported by substantial 

evidence.1

Upon careful review of the record and the parties’ briefs, we affirm.

I

We review the decision of an ALJ as the Commissioner’s final decision 

where, as here, the ALJ denies benefits and the Appeals Council denies review. 

See Doughty v. Apfel, 245 F.3d 1274, 1278 (11th Cir. 2001). “The Commissioner’s 

factual findings are conclusive if supported by substantial evidence.” Ingram v. 

Comm’r of Soc. Sec. Admin., 496 F.3d 1253, 1260 (11th Cir. 2007) (internal 

quotation marks and citations omitted). “‘Substantial evidence is more than a 

scintilla and is such relevant evidence as a reasonable person would accept as 

 1 Although Mr. McCormick argues in his initial brief that the Appeals Council failed to 

sufficiently articulate its rationale for denying review and failed to show that it adequately 

evaluated new evidence, Mr. McCormick withdrew this claim in his reply brief. Mr. McCormick 

also argues in his initial brief that the district court erred in failing to remand under 42 U.S.C. § 

405(g), but he withdrew this claim in his reply brief as well. Accordingly, we will not address 

either issue. See United States v. Daniels, 685 F.3d 1237, 1251 (11th Cir. 2012).

adequate to support a conclusion.’” Crawford v. Comm’r of Soc. Sec., 363 F.3d 

1155, 1158 (11th Cir. 2004) (quoting Lewis v. Callahan, 125 F.3d 1436, 1439 

(11th Cir. 1997)). “Even if the evidence preponderates against the 

[Commissioner’s] factual findings, we must affirm if the decision reached is 

supported by substantial evidence.” Martin v. Sullivan, 894 F.2d 1520, 1529 (11th 

Cir. 1991). The Commissioner’s conclusions of law are reviewed de novo. See 

Ingram 496 F.3d at 1160.

II

An ALJ must perform a five-step evaluation to determine whether a claimant 

has proven that he is disabled. See 20 C.F.R. § 416.920(a)(4). See also McDaniel v. 

Bowen, 800 F.2d 1026, 1030 (11th Cir. 1984). The claimant must prove that (1) he 

has not engaged in “substantial gainful activity”; (2) he has a “severe impairment 

or combination of impairments”; and (3) the impairment(s) “meets or equals” a 

listed impairment qualifying for automatic disability. Jones v. Apfel, 190 F.3d 

1224, 1228 (11th Cir. 1999). If the claimant does not meet the listed standards, he 

must prove that (4) he “is unable to perform past relevant work” in light of his 

residual functional capacity (“RFC”). Id. If the claimant proves he cannot return to 

past relevant work, the ALJ must (5) “determine if there is other work available in 

significant numbers in the national economy that the claimant is able to perform.”

Id.

Step two is a “threshold inquiry” where only the most trivial impairments 

are to be rejected. McDaniel, 800 F.2d at 1031. The claimant’s burden at this stage 

is mild. See id. We have explained that step two serves as a filter, and if any severe 

impairment is found, the requirements of step two are satisfied. See Jamison v. 

Bowen, 814 F.2d 585, 588 (11th Cir. 1987). A single impairment or a combination 

of impairments that together qualify as severe may meet the requirements for step 

two. See id. See also Bowen v. Heckler, 748 F.2d 629, 635 (11th Cir. 1984)

(explaining that where a claimant alleges multiple impairments, “a claim for social 

security benefits based on disability may lie even though none of the impairments, 

considered individually, is disabling”). The ALJ “must make specific and wellarticulated findings as to the effect of the combination of impairments and [ ] 

decide whether the combined impairments cause the claimant to be disabled.” Id. 

At the third step, the ALJ must consider the claimant’s medical condition as 

a whole and determine whether one severe impairment or the combination of 

impairments constitute a disability. See Jamison, 814 F.2d at 588. The claimant 

must meet the criteria from the categories in the Appendix 1 Listings to be 

considered disabled. See § 416.920(a)(4)(iii), (d). As relevant here, Listing 12.04 

outlines mood disorders, including depression and bipolar disorder, and Listing 

12.06 describes anxiety disorders. See 20 C.F.R. § 404, Subpart P, Appendix 1, 

Listings 12.04 and 12.06. 

Case: 14-14428 Date Filed: 07/23/2015 Page: 4 of 8

Step four requires the ALJ to assess the claimant’s residual functional 

capacity and ability to undertake past relevant work. See § 416.920(a)(4)(iv). The 

claimant must prove he can no longer engage in past relevant work. See Jones v. 

Bowen, 810 F.2d 1001, 1005 (11th Cir. 1986). The ALJ must evaluate the 

claimant’s ability to perform all the duties required by past relevant work—

considering the claimant’s impairment(s). See Lucas v. Sullivan, 918 F.2d 1567, 

1574 (11th Cir. 1990). If the ALJ finds that the claimant can perform past relevant 

work, he is not disabled, and there is no need to proceed to the fifth step. Cf.

Jackson v. Bowen, 801 F.2d 1291, 1293 (11th Cir. 1986) (“If a Social Security 

claimant can still do the kind of work he has done in the past, he will be found not 

disabled.”) (internal quotation marks and brackets omitted). 

III

The ALJ did not fail to consider the combined effects of Mr. McCormick’s 

impairments. To satisfy the requirements of step two, the ALJ had to recognize the 

existence of a severe impairment or combination of impairments. See Jamison, 814 

F.2d at 588. The ALJ considered Mr. McCormick’s mood disability and history of 

special education, and that was sufficient to proceed to step three. See D.E. 5-3 at 

29. And, as explained above, step two is merely a filter, and any error in 

considering an additional impairment is harmless since it does not factor into the 

determination of disability. See Jamison, 814 F.2d at 588. See also Diorio v. 

Case: 14-14428 Date Filed: 07/23/2015 Page: 5 of 8 
6

Heckler, 721 F.2d 726, 728 (11th Cir. 1983) (holding that an error by ALJ in one 

step with no bearing on final determination was harmless).

At step three, the ALJ compared medical evidence to the required Listings, 

and found that Mr. McCormick’s impairments, even in combination, did not meet 

the level of severity contemplated in Listings 12.04 (bipolar and depressive 

disorders) and 12.06 (anxiety disorders). See D.E. 5-3 at 30. The ALJ determined 

that Mr. McCormick’s impairments amounted to a “moderate” restriction, and did 

not reach the “marked” restriction required for a finding of disability. Id. We 

conclude that the ALJ’s determination “constitutes evidence that he considered the 

combined effects of [Mr. McCormick’s] impairments.” Wilson v. Barnhart, 284 

F.3d 1219, 1224 (11th Cir. 2002).

The ALJ also considered the impairments individually and in combination 

when he evaluated Mr. McCormick’s RFC under step four. The ALJ found that 

Mr. McCormick could meet the mental and physical demands of his past work as a 

shipping and receiving weigher despite his impairments. The ALJ reviewed 

medical records and determined that any claimed conditions, such as bipolar 

disorder or post-traumatic stress disorder, did not prevent Mr. McCormick from 

performing recent past work. See D.E. 5-3 at 33–34.

Case: 14-14428 Date Filed: 07/23/2015 Page: 6 of 8 
7

In sum, we conclude that the ALJ did not fail to consider the combined 

effects of impairments in determining that Mr. McCormick is not disabled under § 

416.920.

IV

The claimant bears the burden of proving he is unable to perform past 

relevant work. See Lucas, 918 F.2d at 1571. The ALJ must take all the duties of a 

claimant’s past work into consideration and evaluate whether the claimant can still 

perform them in spite of the severe impairment or combination of impairments. See 

id at 1574. 

Mr. McCormick testified that he had previously worked in a warehouse 

doing shipping and receiving. A vocational expert testified that a hypothetical 

person with Mr. McCormick’s RFC could perform as a shipper and receiver, 

according to the Dictionary of Occupational Titles’ (“DOT”) job description. See

D.E. 5-3 at 34, 50. Based this testimony—and taking Mr. McCormick’s 

impairments and limitations into account—the ALJ determined that Mr. 

McCormick could perform relevant past work in spite of his limitations. 

On this record, we conclude that the ALJ’s determination is supported by 

substantial evidence. Accordingly, we must affirm. See Ingram, 496 F.3d at 1260.

V

Based on the foregoing, we affirm the Commission’s decision.
