PAM J. PHELPS, Plaintiff,
CAROLYN W. COLVIN,  ACTING COMMISSIONER OF SOCIAL SECURITY, Defendant.
DECISION AND ORDER
WILLIAM M. SKRETNY, District Judge.
1. Plaintiff Pam Phelps challenges an Administrative Law Judge's ("ALJ") determination that she was not disabled within the meaning of the Social Security Act ("the Act") from April 27, 2009, when she was involved in a motor vehicle accident, to March 3, 2011, when she was involved in a second motor vehicle accident.
2. On September 18, 2009, Phelps filed an application for Disability Insurance Benefits ("DIB") under Title II of the Act. She alleged she had been disabled since April 27, 2009, due to back and neck injuries she sustained in a motor vehicle accident. (R. 213-16, 254-65.) The application were denied. (R. 126-29.) At Phelps' request, a hearing was held before Administrative Law Judge Nancy Gregg Pasiecznik on March 28, 2011 (R. 52-78), followed by a supplemental hearing on June 15, 2011 (R. 79-117). Phelps appeared in person, with representation, and testified. (Id.)
3. ALJ Pasiecznik considered the case de novo, and on July 13, 2011, issued a written decision finding Plaintiff disabled beginning March 3, 2011, when she was involved in a second motor vehicle accident, but not disabled prior to that date. (R. 19-49.) Phelps filed a request for review with the Appeals Council, which denied the request on September 8, 2012. She then commenced this civil action on October 15, 2012, challenging the Commissioner's final decision.
4. On April 24, 2013, the Commissioner and Phelps each filed a motion for judgment on the pleadings pursuant to Rule 12(c) of the Federal Rules of Civil Procedure. The motions were fully briefed on June 14, 2014, at which time this Court took the matter under advisement without oral argument. For the reasons set forth below, the Commissioner's motion is denied, Phelps' motion is granted, and this case will be remanded.
5. A court reviewing a denial of disability benefits may not determine de novo whether an individual is disabled. See 42 U.S.C. §§ 405(g), 1383(c)(3); Wagner v. Sec'y of Health & Human Servs. , 906 F.2d 856, 860 (2d Cir. 1990). Rather, the Commissioner's determination will be reversed only if it is not supported by substantial evidence or there has been a legal error. See Grey v. Heckler , 721 F.2d 41, 46 (2d Cir. 1983); Marcus v. Califano , 615 F.2d 23, 27 (2d Cir. 1979). Substantial evidence is that which amounts to "more than a mere scintilla"; it has been defined as "such relevant evidence as a reasonable mind might accept as adequate to support a conclusion." Richardson v. Perales , 402 U.S. 389, 401, 91 S.Ct. 1420, 1427, 28 L.Ed.2d 842 (1971). Where evidence is deemed susceptible to more than one rational interpretation, the Commissioner's conclusion must be upheld. See Rutherford v. Schweiker , 685 F.2d 60, 62 (2d Cir. 1982). substantial evidence, a reviewing court considers the whole record, examining the evidence from both sides, because an analysis of the substantiality of the evidence must also include that which detracts from its weight." Williams on Behalf of Williams v. Bowen , 859 F.2d 255, 258 (2d Cir. 1988). If supported by substantial evidence, the Commissioner's finding must be sustained "even where substantial evidence may support the plaintiff's position and despite that the court's independent analysis of the evidence may differ from the [Commissioner's]." Rosado v. Sullivan , 805 F.Supp. 147, 153 (S.D.N.Y. 1992). In other words, this Court must afford the Commissioner's determination considerable deference, and may not substitute "its own judgment for that of the [Commissioner], even if it might justifiably have reached a different result upon a de novo review." Valente v. Sec'y of Health & Human Servs. , 733 F.2d 1037, 1041 (2d Cir. 1984).
7. The Commissioner has established a five-step sequential evaluation process to determine whether an individual is disabled as defined under the Act. See 20 C.F.R. §§ 404.1520, 416.920. The United States Supreme Court recognized the validity of this analysis in Bowen v. Yuckert , 482 U.S. 137, 140-142, 107 S.Ct. 2287, 2291, 96 L.Ed.2d 119 (1987), and it remains the proper approach for analyzing whether a claimant is disabled.
8. This five-step process is detailed below:
First, the [Commissioner] considers whether the claimant is currently engaged in substantial gainful activity. If he is not, the [Commissioner] next considers whether the claimant has a "severe impairment" which significantly limits his physical or mental ability to do basic work activities. If the claimant suffers such an impairment, the third inquiry is whether, based solely on medical evidence, the claimant has an impairment which is listed in Appendix 1 of the regulations. If the claimant has such an impairment, the [Commissioner] will consider him disabled without considering vocational factors such as age, education, and work experience; the [Commissioner] presumes that a claimant who is afflicted with a "listed" impairment is unable to perform substantial gainful activity. Assuming the claimant does not have a listed impairment, the fourth inquiry is whether, despite the claimant's severe impairment, he has the residual functional capacity to perform his past work. Finally, if the claimant is unable to perform his past work, the [Commissioner] then determines whether there is other work which the claimant could perform.
Berry v. Schweiker , 675 F.2d 464, 467 (2d Cir. 1982) (per curiam); see also Rosa v. Callahan , 168 F.3d 72, 77 (2d Cir. 1999); 20 C.F.R. § 404.1520.
9. Although the claimant has the burden of proof as to the first four steps, the Commissioner has the burden of proof on the fifth and final step. See Bowen , 482 U.S. at 146 n. 5; Ferraris v. Heckler , 728 F.2d 582, 584 (2d Cir. 1984). The final step of this inquiry is, in turn, divided into two parts. First, the Commissioner must assess the claimant's job qualifications by considering his physical ability, age, education, and work experience. Second, the Commissioner must determine whether jobs exist in the national economy that a person having the claimant's qualifications could perform. See 42 U.S.C. § 423(d)(2)(A); 20 C.F.R. § 404.1520(f); Heckler v. Campbell , 461 U.S. 458, 460, 103 S.Ct. 1952, 1954, 76 L.Ed.2d 66 (1983).
10. In this case, the ALJ made the following findings with regard to the five-step process: (1) Phelps had not engaged in substantial gainful activity since her alleged disability onset date of April 27, 2009 (R. 28); (2) her degenerative disc disease and degenerative joint changes in the cervical spine at C5-6, with mild left-sided foraminal encroachment; degenerative disc changes in the mid-to-lower thoracic spine with levoscoliosis and thoracid kyphosis; very mild disc desiccation at L3-4; mild disc bulge of the anulus and mild facet arthropathy at L4-5; mild right-sided facet arthropathy and a broad-based mild diffuse left paramedian disc herniation at L5-S1 with mild displacement of the left S1 nerve root with significant deformity; mild encroachment upon the left neural foramen at the left L5 nerve root with left L5 and/or S1 radiculopathy; conjoined S1 and S2 nerve roots; myofascial pain; osteoporosis of the thoracic spine; left shoulder impingement syndrome that developed after the March 3, 2011 accident; adjustment disorder with mixed anxiety and depressed mood; and pain associated with her general medical condition are severe impairments within the meaning of the Act (Id.); (3) these impairments did not meet or medically equal any of the impairments listed in 20 C.F.R. Part 404, Subpart P, Appendix 1 (R. 11); (4) prior to March 3, 2011, Phelps retained the residual functional capacity ("RFC") to perform sedentary work; but her conditions worsened after the second motor vehicle accident, and she has been disabled from working since March 3, 2011 (R. 34-41); (5) since April 27, 2009, she has been unable to perform her past relevant work (R. 42); and (6) until Phelps became disabled on March 3, 2011, jobs existed in substantial number in the national economy that an individual of her age, education, past relevant experience, and RFC could perform (R. 42).
11. Phelps challenges the determination of her disability onset date on the grounds that: (a) the ALJ selectively adopted only portions of her treating chiropractor's opinion, (b) did not properly weigh the chiropractor's opinion under SSR 06-03, and (c) relied on testimony from a vocational expert that was inconsistent with the Dictionary of Occupational Titles ("DOT").
12. The Social Security regulations distinguish between "acceptable medical sources, " including licensed physicians and psychologists, 20 C.F.R. § 416.913(a), and "other sources, " such as chiropractors and nurse-practitioners, who are not "acceptable medical sources, " § 416.913(d)(1). "[O]nly acceptable medical sources' can be considered treating sources, as defined in 20 CFR 404.1502 and 416.902, whose medical opinions may be entitled to controlling weight." SSR No. 06-03p, 2006 SSR LEXIS 5, at *4. Nevertheless, opinions from "other sources" "should be evaluated on key issues such as impairment severity and functional effects, along with the other relevant evidence in the file." Id. at *8. Sources not technically deemed "acceptable medical sources, " such as chiropractors, are ...
