MEMORANDUM OPINION AND ORDER
LEONARD T. STRAND, Magistrate Judge.
Plaintiff Julie Loftis, proceeding on behalf of her now-deceased husband, Travis Loftis, seeks judicial review of a final decision of the Commissioner of Social Security (the Commissioner) denying Travis's applications for Social Security Disability Insurance benefits (DIB) and Supplemental Security Income benefits (SSI) under Titles II and XVI of the Social Security Act, 42 U.S.C. § 401 et seq. (Act). Julie contends that the administrative record (AR) does not contain substantial evidence to support the Commissioner's decision that Travis was not disabled during the relevant period of time. For the reasons that follow, I find that the Commissioner's decision must be reversed and remanded for further proceedings in accordance with this order.
Travis was born in 1974. AR 132. He completed high school and attended four years of college, but did not obtain a degree. AR 27. He had past relevant work as a sales representative and construction laborer. AR 258.
Travis protectively filed his applications for SSI and DIB on, respectively, August 31, 2009, and December 3, 2009. AR 132-39. His DIB application alleged an onset date of November 1, 1995, while his SSI application alleged an onset date of January 1, 2009. AR 132, 136. Both applications were denied initially and on reconsideration. AR 8. Travis then requested a hearing, which was conducted May 12, 2011, by Administrative Law Judge (ALJ) Theodore P. Kennedy. Id. Travis testified during the hearing, as did Julie and a vocational expert (VE). AR 24-56.
The ALJ issued a decision denying Travis's applications on June 1, 2011. AR 8-17. On September 26, 2012, the Appeals Council denied Travis's request for review. AR 1-3. As such, the ALJ's decision is the final decision of the Commissioner. AR 1; see also 20 C.F.R. §§ 404.981, 416.1481.
On November 21, 2012, Julie commenced an action in this court seeking review of the ALJ's decision. On December 28, 2012, with the parties' consent, United States District Judge Mark W. Bennett transferred the case to me. The parties have briefed the issues and the matter is now fully submitted.
Disability Determinations and the Burden of Proof
A disability is defined as the inability to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or that has lasted or can be expected to last for a continuous period of not less than twelve months. 42 U.S.C. §§ 423(d)(1)(A), 1382c(a)(3)(A); 20 C.F.R. §§ 404.1505, 416.905. A claimant has a disability when the claimant is "not only unable to do his previous work but cannot, considering his age, education, and work experience, engage in any other kind of substantial gainful work which exists... in significant numbers either in the region where such individual lives or in several regions of the country." 42 U.S.C. §§ 423(d)(2)(A), 1382c(a)(3)(B).
To determine whether a claimant has a disability within the meaning of the Social Security Act, the Commissioner follows a five-step sequential evaluation process outlined in the regulations. 20 C.F.R. §§ 404.1520, 416.920; see Kirby v. Astrue, 500 F.3d 705, 707 (8th Cir. 2007). First, the Commissioner will consider a claimant's work activity. If the claimant is engaged in substantial gainful activity, then the claimant is not disabled. 20 C.F.R. §§ 404.1520(a)(4)(i), 416.920(a)(4)(i).
Second, if the claimant is not engaged in substantial gainful activity, the Commissioner looks to see "whether the claimant has a severe impairment that significantly limits the claimant's physical or mental ability to perform basic work activities." Dixon v. Barnhart, 353 F.3d 602, 605 (8th Cir. 2003). "An impairment is not severe if it amounts only to a slight abnormality that would not significantly limit the claimant's physical or mental ability to do basic work activities." Kirby, 500 F.3d at 707; see 20 C.F.R. §§ 404.1520(c), 404.1521(a), 416.920(c), 416.921(a).
The ability to do basic work activities is defined as "the abilities and aptitudes necessary to do most jobs." 20 C.F.R. §§ 404.1521(b), 416.921(b). These abilities and aptitudes include (1) physical functions such as walking, standing, sitting, lifting, pushing, pulling, reaching, carrying, or handling; (2) capacities for seeing, hearing, and speaking; (3) understanding, carrying out, and remembering simple instructions; (4) use of judgment; (5) responding appropriately to supervision, co-workers, and usual work situations; and (6) dealing with changes in a routine work setting. Id. §§ 404.1521(b)(1)-(6), 416.921(b)(1)-(6); see Bowen v. Yuckert, 482 U.S. 137, 141, 107 S.Ct. 2287, 2291 (1987). "The sequential evaluation process may be terminated at step two only when the claimant's impairment or combination of impairments would have no more than a minimal impact on her ability to work." Page v. Astrue, 484 F.3d 1040, 1043 (8th Cir. 2007) (internal quotation marks omitted).
Third, if the claimant has a severe impairment, then the Commissioner will consider the medical severity of the impairment. If the impairment meets or equals one of the presumptively disabling impairments listed in the regulations, then the claimant is considered disabled, regardless of age, education, and work experience. 20 C.F.R. §§ 404.1520(a)(4)(iii), 404.1520(d), 416.920(a)(4)(iii), 416.920(d); see Kelley v. Callahan, 133 F.3d 583, 588 (8th Cir. 1998).
Fourth, if the claimant's impairment is severe, but it does not meet or equal one of the presumptively disabling impairments, then the Commissioner will assess the claimant's RFC to determine the claimant's "ability to meet the physical, mental, sensory, and other requirements" of the claimant's past relevant work. 20 C.F.R. §§ 404.1520(a)(4)(iv), 404.1545(a)(4), 416.920(a)(4)(iv), 416.945(a)(4). "RFC is a medical question defined wholly in terms of the claimant's physical ability to perform exertional tasks or, in other words, what the claimant can still do despite his or her physical or mental limitations." Lewis v. Barnhart, 353 F.3d 642, 646 (8th Cir. 2003) (internal quotation marks omitted); see 20 C.F.R. §§ 404.1545(a)(1), 416.945(a)(1). The claimant is responsible for providing evidence the Commissioner will use to make a finding as to the claimant's RFC, but the Commissioner is responsible for developing the claimant's "complete medical history, including arranging for a consultative examination(s) if necessary, and making every reasonable effort to help [the claimant] get medical reports from [the claimant's] own medical sources." 20 C.F.R. §§ 404.1545(a)(3), 416.945(a)(3). The Commissioner also will consider certain non-medical evidence and other evidence listed in the regulations. See id. If a claimant retains the RFC to perform past relevant work, then the claimant is not disabled. Id. §§ 404.1520(a)(4)(iv), 416.920(a)(4)(iv).
Fifth, if the claimant's RFC as determined in Step Four will not allow the claimant to perform past relevant work, then the burden shifts to the Commissioner to prove that there is other work that the claimant can do, given the claimant's RFC as determined at Step Four, and his or her age, education, and work experience. See Bladow v. Apfel, 205 F.3d 356, 358-59 n.5 (8th Cir. 2000). The Commissioner must prove not only that the claimant's RFC will allow the claimant to make an adjustment to other work, but also that the other work exists in significant numbers in the national economy. Eichelberger v. Barnhart, 390 F.3d 584, 591 (8th Cir. 2004); 20 C.F.R. §§ 404.1520(a)(4)(v), 416.920(a)(4)(v). If the claimant can make an adjustment to other work that exists in significant numbers in the national economy, then the Commissioner will find the claimant is not disabled. If the claimant cannot make an adjustment to other work, then the Commissioner will find that the claimant is disabled. 20 C.F.R. §§ 404.1520(a)(4)(v), 416.920(a)(4)(v). At Step Five, even though the burden of production shifts to the Commissioner, the burden of persuasion to prove disability remains on the claimant. Stormo v. Barnhart, 377 F.3d 801, 806 (8th Cir. 2004).
