ORDER AFFIRMING COMMISSIONER

The matter before me is plaintiffs Complaint [# l],1 filed December 10, 2013, seeking review of the Commissioner’s decision denying plaintiffs claims for disability insurance benefits and supplemental security income benefits under Titles II and XVI of the Social Security Act, 42 U.S.C. § 401, et seq. I have jurisdiction to review the Commissioner’s final decision under 42 U.S.C. § 405(g). The matter has been fully briefed, obviating the need for oral argument. I affirm.

I. FACTUAL AND PROCEDURAL BACKGROUND

Plaintiff alleges that he is disabled as a result of Leriche’s syndrome,2 degenera*1311tive joint disease of the hips and lumbar spine, and depression. After his applications for disability insurance benefits and supplemental security income benefits were denied, plaintiff requested a hearing before an administrative law judge. This hearing was held on April 23, 2012. At the time of the hearing, plaintiff was 64 years old. He has a high school equivalency diploma and past relevant work experience as a demonstrator and telemarketer. He has not engaged in substantial gainful activity since November 7, 2008, his amended alleged date of onset.

The ALJ found that plaintiff was not disabled and therefore not entitled to disability insurance benefits or supplemental security income benefits. Although the medical evidence established that plaintiff suffered from severe impairments, the judge concluded that the severity of those impairments did not meet or equal any impairment listed in the social security regulations. Plaintiffs depression was determined to be non-severe. The ALJ found that plaintiff had the residual functional capacity to perform a range of light work with certain postural and environmental restrictions. Based on these findings, the ALJ concluded that plaintiff was capable of performing his past relevant work as a telemarketer. He therefore found plaintiff not disabled at step 4 of the sequential evaluation. Plaintiff appealed this decision to the Appeals Council. The Council affirmed. Plaintiff then filed this action in federal court.

II. STANDARD OF REVIEW

A person is disabled within the meaning of the Social Security Act only if his physical and/or mental impairments preclude him from performing both his previous work and any other “substantial gainful work which exists in the national economy.” 42 U.S.C. § 423(d)(2). “When a claimant has one or more severe impairments the Social Security [Act] requires the [Commissioner] to consider the combined effects of the impairments in making a disability determination.” Campbell v. Bowen, 822 F.2d 1518, 1521 (10th Cir. 1987) (citing 42 U.S.C. § 423(d)(2)(C)). However, the mere existence of a severe impairment or combination of impairments does not require a finding that an individual is disabled within the meaning of the Social Security Act. To be disabling, the claimant’s condition must be so functionally limiting as to preclude any substantial gainful activity for at least twelve consecutive months. See Kelley v. Chater, 62 F.3d 335, 338 (10th Cir. 1995).

The Commissioner has established a quinquepartite sequential evaluation process for determining whether a claimant is disabled:

1. The ALJ must first ascertain whether the claimant is engaged in substantial gainful activity. A claimant who is working is not disabled regardless of the medical findings.

2. The ALJ must then determine whether the claimed impairment is “severe.” A “severe impairment” must significantly limit the claimant’s physical or mental ability to do basic work activities.

3. The ALJ must then determine if the impairment meets or equals in severity certain impairments described in Appendix 1 of the regulations.

4. If the claimant’s impairment does not meet or equal a listed impairment, the ALJ must determine *1312whether the claimant can perform his past work despite any limitations.

5. If the claimant does not have the residual functional capacity to perform her past work, the ALJ must decide whether the claimant can perform any other gainful and substantial work in the economy. This determination is made on the basis of the claimant’s age, education, work experience, and residual functional capacity.

20 C.F.R. § 404.1520(a)(4)(i)-(v).3 See also Williams v. Bowen 844 F.2d 748, 750-52 (10th Cir. 1988). The claimant has the initial burden of establishing a disability in the first four steps of this analysis. Bowen v. Yuckert, 482 U.S. 137, 146 n. 5, 107 S.Ct. 2287, 2294 n. 5, 96 L.Ed.2d 119 (1987). The burden then shifts to the Commissioner to show that the claimant is capable of performing work in the national economy. Id. A finding that the claimant is disabled or not disabled at any point in the five-step review is conclusive and terminates the analysis. Casias v. Secretary of Health & Human Services, 933 F.2d 799, 801 (10th Cir. 1991).

Review of the Commissioner’s disability decision is limited to determining whether the ALJ applied the correct legal standard and whether the decision is supported by substantial evidence. Hamilton v. Secretary of Health and Human Services, 961 F.2d 1495, 1497-98 (10th Cir. 1992); Brown v. Sullivan, 912 F.2d 1194, 1196 (10th Cir. 1990). Substantial evidence is evidence a reasonable mind would accept as adequate to support a conclusion. Brown, 912 F.2d at 1196. It requires more than a scintilla but less than a preponderance of the evidence. Hedstrom v. Sullivan, 783 F.Supp. 553, 556 (D.Colo. 1992). “Evidence is not substantial if it is overwhelmed by other evidence in the record or constitutes mere conclusion.” Musgrave v. Sullivan, 966 F.2d 1371, 1374 (10th Cir. 1992). Further, “if the ALJ failed to apply the correct legal test, there is a ground for reversal apart from a lack of substantial evidence.” Thompson v. Sullivan, 987 F.2d 1482, 1487 (10th Cir. 1993). Although a reviewing court should meticulously examine the record, it may not reweigh the evidence or substitute its discretion for that of the Commissioner. Id.

III. LEGAL ANALYSIS

Plaintiff alleges that the ALJ erred in concluding that his depression did not constitute a severe impairment, in assessing his residual functional capacity, and in failing to develop the record regarding the requirements of plaintiffs past relevant work prior to determining that he still could perform that work.. Finding no reversible error, I affirm.

Plaintiff claims first that the ALJ erred in finding, at step 2 of the sequential evaluation, that his depression was not a severe impairment because it did not cause more than minimal limitations in plaintiffs ability to perform the basic mental activities of work. (Tr. 25.) See 20 C.F.R. § 404.1521(a) (“An impairment or combination of impairments is not severe if it does not significantly limit your physical or mental ability to do basic work activities.”). Although the threshold for showing severity is de minimis, the mere existence of a medically determinable impairment per se is insufficient to meet it. Hinkle v. Apfel, *1313132 F.3d 1349, 1352 (10th Cir. 1997). Plaintiff has shown no more than that here.

As the ALJ noted, plaintiff never received any type of mental health treatment or counseling; nor has any treating source ever indicated that he experiences any type of psychologically significant symptoms. (Tr. 25.) The consultative examiner who examined plaintiff at the request of the agency, although diagnosing plaintiff with a depressive disorder, noted that “if this individual is to be given Social Security Disability, it needs to be based on his physical problems.” (Tr. 406.)4 Moreover, any potential error in the failure to denominate depression as a severe impairment was rendered harmless when the ALJ found other impairments to be severe and proceeded to subsequent steps of the sequential analysis. See Dray v. Astrue, 353 Fed.Appx. 147, 149 (10th Cir. 2009).5

Plaintiff complains of various alleged errors in the determination of his residual functional capacity. Ultimately, none warrants remand.

Plaintiff first faults the ALJ for his reliance on the opinion of the non-examining state agency physician, Dr. Kimberlee Terry, who reviewed the medical evidence of record and concluded that plaintiff could sit up to six hours in an eight-hour day, stand and walk up to two hours a day, and lift up to 20 pounds occasionally and 10 pounds frequently. She also suggested certain other postural and environmental limitations. (Tr. 82-84.) The ALJ assigned Dr. Terry’s opinion “great weight” (Tr. 30), and indeed, her suggested restrictions were incorporated fully into his residual functional capacity assessment (Tr. 26-27).

In challenging the ALJ’s reliance on this opinion, plaintiff notes that Dr. Terry never examined plaintiff.6 This observation is accurate, but standing alone, irrelevant. “State agency medical and psychological consultants are highly qualified physicians and psychologists who are experts in the evaluation of the medical issues in disability claims under the Act.” Social Security Ruling 96-6p, 1996 WL 374180 at *2 (SSA July 2, 1996). Although their opinions generally are entitled to less weight than those of treating and examining sources, “[i]n appropriate circumstances, opinions from State agency medical and psychological consultants and other program physicians and psychologists may be entitled to greater weight than the opinions of treating or examining sources.” Id. at *3.

Moreover, Dr. Terry’s opinion was largely consistent with the opinions of both *1314the consultative examiner and. plaintiffs own treating doctor. (See Tr. 397-401, 596-597)7 The ALJ examined each of these opinions and assigned them each weight based on their consistency with the medical and other evidence of record, including plaintiffs own testimony. (Tr. 29-30.) It is the ALJ’s responsibility to resolve conflicts in the evidence, and he appropriately discharged that duty in assessing the various medical opinions of record here.8 See Reyes v. Bowen, 845 F.2d 242, 245 (10th Cir. 1988).

Plaintiff argues next that the ALJ failed to consider the combined effect of all his impairments, severe and non-severe, in assessing his residual functional capacity. See Social Security Ruling 85-28, 1985 WL 56856 at *1-2 (SSA 1985). The record belies this assertion. The ALJ not only discussed the psychological consultative examiner’s opinion that plaintiff would have no more than mild difficulties interacting with the public, colleagues, and supervisors (Tr. 25), but also noted plaintiffs own statements that he could pay attention to and follow instructions, get along with authority figures, and handle changes in routine and stress (Tr. 27, 247-248). Moreover, simply because the ALJ found that plaintiff had mild restrictions in the four “paragraph B” criteria assessed at step 2 of the sequential evaluation, he was not obligated to include a similar limitation in his residual functional capacity determination. See Beasley v. Colvin, 520 Fed.Appx. 748, 754 (10th Cir. 2013). I thus perceive no reversible error in the ALJ’s implicit determination that plaintiff could perform the mental demands of his past relevant work. See id.

Nor did the ALJ err in determining plaintiffs residual functional capacity by discrediting his subjective complaints of pain and functional limitations. Although plaintiff argues that the ALJ did not apply the analysis required by Luna v. Bowen, 834 F.2d 161,163-64 (10th Cir. 1987), in the narrative portion of his residual functional capacity analysis,9 a review of the ALJ’s opinion actually belies this argument. The ALJ not only specifically cited to the applicable standards (see Tr. 27), but also noted that he had considered plaintiffs allegations in light of a number of the credibility factors contemplated by the regulations (see Tr. 28). The ALJ gave clear, specific, legitimate reasons linked to specific evidence in the record for his credibility assessment. His findings in this regard find support in the record, and his determina*1315tion therefore is entitled to substantial deference. White v. Barnhart, 287 F.3d 903, 909 (10th Cir. 2001) (“[Credibility determinations ‘are peculiarly the province of the finder of fact,’ and should not be upset if supported by substantial evidence.”). See also Qualls v. Apfel, 206 F.3d 1368, 1372 (10th Cir. 2000). Accordingly, I find no reversible error on this basis either.

Finally, plaintiff maintains that the ALJ erred at step 4 by finding that plaintiff could perform his past relevant work without adequately developing the record regarding the requirements of that work. See Social Security Ruling 82-62, 1982 WL 31386 at *3 (SSA 1982); Henrie v. United States Department of Health & Human Services, 13 F.3d 359, 361 (10th Cir. 1993). In this regard, plaintiff notes that although the telemarketer job as he performed it required him to sit eight hours a day, the ALJ determined that he had the residual functional capacity to sit for up to six hours a day.

Although the ALJ mistakenly stated that the vocational expert’s testimony that plaintiff could perform the telemarketer job was based on the work as plaintiff performed it (Tr. 31), in fact the vocational expert testified to the description of the job as set forth in the Dictionary of Occupational Titles (Tr. 56). The Dictionary of Occupational Titles describes jobs as they are generally performed in the national economy, not as any particular individual may have performed them in a specific instance. See 20 C.F.R. § 404.1566(d)(1); Bowman v. Astrue, 511 F.3d 1270, 1273 n. 1 (10th Cir. 2008). Yet a determination that a claimant can perform the requirements of his past relevant work under either of these rubrics is sufficient to substantiate the Commissioner’s burden at step 5. See Social Security Ruling 82-61, 1982 WL 31387 at *1 (SSA 1982); Andrade v. Secretary of Health & Human Services, 985 F.2d 1045, 1050-51 (10th Cir. 1993).

The vocational expert here testified that a person limited to sitting six hours a day could perform the telemarketer job. (Tr. 57.) There was no need to further develop the record because the evidence was sufficient to permit a determination as to the demands of plaintiffs past relevant work. See Lohse v. Shalala, 1994 WL 263699 at *3, 28 F.3d 113 (10th Cir. June 16, 1994) (duty to further develop record arises only “[i]f the vocational and disability reports the claimant submits are not sufficient to match the claimant’s past relevant work with a job description in the Dictionary of Occupational Titles ”). Thus, any error in citing the correct basis for the step 5 determination was undoubtedly harmless.10 See Bernal v. Bowen, 851 F.2d 297, 303 (10th Cir. 1988) (mere fact of error does not warrant remand if the ALJ’s determination is otherwise supported by substantial evidence).

IV. ORDERS

For these reasons, I find no reversible error in the ALJ’s disability determination, which accordingly must be affirmed.

THEREFORE IT IS ORDERED that the conclusion of the Commissioner through the Administrative Law Judge that plaintiff was not disabled is AFFIRMED.
