Plaintiff appeals from a denial of disability benefits by the Commissioner of Social Security ("the Commissioner"). The action is one brought pursuant to 42 U.S.C. § 405(g) to review the Commissioner's final determination.
On July 24, 2012, plaintiff, then thirty-one years old, filed applications for a period of disability and disability insurance benefits, and for supplemental security income, alleging an inability to work since January 1, 2011. (Dkt. # 7 at 20).1 Those applications were initially denied. Plaintiff requested a hearing, which was held June *15925, 2014 before Administrative Law Judge ("ALJ") Connor O'Brien. On September 23, 2014, the ALJ issued a decision finding plaintiff not disabled. (Dkt. # 7 at 20-30). That decision became the final decision of the Commissioner when the Appeals Council denied review on January 19, 2016. (Dkt. # 7 at 1-4). Plaintiff now appeals.
The plaintiff has moved, and the Commissioner has cross moved, for judgment on the pleadings pursuant to Fed. R. Civ. Proc. 12(c). For the reasons set forth below, plaintiff's motion (Dkt. # 12) is granted, the Commissioner's cross motion (Dkt. # 16) is denied, and the matter is remanded for further proceedings.
DISCUSSION
An ALJ applies a well-established five-step evaluation process to determine whether a claimant is disabled within the meaning of the Social Security Act, familiarity with which is presumed. See Bowen v. City of New York , 476 U.S. 467, 470-71, 106 S.Ct. 2022, 90 L.Ed.2d 462 (1986). The Commissioner's decision that plaintiff is not disabled must be affirmed if it is supported by substantial evidence, and if the ALJ has applied the correct legal standards. See 42 U.S.C. § 405(g) ; Machadio v. Apfel , 276 F.3d 103, 108 (2d Cir. 2002).
Here, the ALJ determined that since the alleged onset date of January 1, 2011, plaintiff has suffered from the following severe impairments: seizure disorder, degenerative disc disease of the lumbar spine, menorrhagia (heavy menstrual bleeding) post endometrial ablation and hysterectomy, obesity, hypertension, hyperthyroidism, and depression. (Dkt. # 7 at 23).
After reviewing of the evidence of record, the ALJ found that the plaintiff has retained the residual functional capacity ("RFC") to perform sedentary work, except that she requires a sit/stand option that allows her to change positions every 60 minutes for up to 5 minutes without leaving her workstation. Plaintiff cannot climb ropes, ladders or scaffolds, and cannot balance on narrow, slippery or moving surfaces. She can occasionally stoop, crouch, kneel and crawl, and cannot tolerate exposure to hazards, such as unprotected heights or dangerous machinery. Plaintiff can tolerate occasional exposure to extreme temperatures, wetness, humidity and concentrated airborne irritants. She cannot work in isolation, can tolerate only occasional changes in the work setting, can have occasional interaction with the public, cannot perform teamwork, but can meet daily goals. She cannot maintain an hourly, machine driven, assembly line production rate. (Dkt. # 7 at 24-25).
When presented with this RFC, vocational expert Carol G. McManus testified that plaintiff could perform the positions of call-out operator, telephone quotation clerk, and table worker. (Dkt. # 7 at 29).
Plaintiff argues that the ALJ erred when she assessed the effect of plaintiff's depression on her RFC without the benefit of a medical opinion, and that her decision was therefore a lay opinion, based on an incomplete record. The Court concurs.
"Because a hearing on disability benefits is a non-adversarial proceeding, the ALJ generally has an affirmative obligation to develop the administrative record. This duty exists even when the claimant is represented by counsel." Perez v. Chater , 77 F.3d 41, 47 (2d Cir. 1996). While it is not per se error for an ALJ to make an RFC determination without relying on a medical opinion, the ALJ's determination must be supported by substantial evidence of record. See Tankisi v. Commissioner , 521 Fed.Appx. 29 (2d Cir. 2013). Thus, where the record is not otherwise complete and fails to meaningfully address a claimant's *160functional physical and/or mental limitations, the ALJ's duty to further develop the record is triggered, and the ALJ's failure to satisfy that duty is reversible error. See Williams v. Colvin , 2016 U.S. Dist. LEXIS 51621 at *12-*13 (W.D.N.Y. 2016).
Here, although the ALJ found that plaintiff's severe impairments included depression, the record was devoid of medical opinion evidence concerning the plaintiff's mental RFC. (Dkt. # 7 at 26).2 Instead, the ALJ stated that her findings concerning the effects of plaintiff's depression were based on selected statements from the treatment records of plaintiff's treating internist, Dr. Bruce MacKellar (in particular, three occasions on which plaintiff reported significant improvement with antidepressant medications), and the fact that plaintiff was referred to counseling by Dr. MacKellar, but "stopped going." (Dkt. # 7 at 27) ("[r]egarding the claimant[']s mental impairments, records indicate that the claimant has had complaints of depression and anxiety...However, the claimant indicated that her symptoms had improved on medication...The claimant was referred to counseling but stopped going because she felt like it was not doing anything for her...").
While Dr. MacKellar's treatment notes and plaintiff's treatment history are undoubtedly relevant, neither provides any meaningful, objective indication of plaintiff's ability to perform the mental and/or physical demands of work. In any event, "the ALJ's own interpretation of [a treating physician's] treatment notes does not supersede the need for a medical source to weigh in on [a claimant's] functional limitations." Hooper , 199 F.Supp.3d 796 at 816 (citing Ramos v. Colvin , 2015 WL 925965 at *10, 2015 U.S. Dist. LEXIS 26590 at *26 (W.D.N.Y. 2015) ).
Stated simply, the record lacks a useful medical opinion by any treating or examining source that addresses whether and to what extent plaintiff's mental impairments impact her ability to perform work-related functions. As such, the ALJ was required to obtain a consultative examination and/or seek additional opinion evidence from plaintiff's treating physician. See Hooper v. Colvin , 199 F.Supp.3d 796, 815 (S.D.N.Y. 2016) (remand is required where ALJ "made [claimant's] disability determination based on a record devoid of any truly complete medical opinion"). See also Haymond v. Colvin , 2014 WL 2048172 at *7, 2014 U.S. Dist. LEXIS 68511 at *22 (W.D.N.Y. 2014) (remand is required where "no psychiatrist, psychologist, social worker, or counselor examined Plaintiff and gave an opinion regarding the functional limitations caused by her...mental impairments").
The Commissioner argues that because the record reflects only minor psychological *161impairments, the ALJ was within her discretion to make a "common sense judgment" concerning the claimant's limitations, and no medical opinion evidence was necessary. Gross v. Astrue , 2014 WL 1806779 at *18, 2014 U.S. Dist. LEXIS 63251 at *51 (W.D.N.Y. 2014) (quoting House v. Astrue , 2013 WL 422058 at *4, 2013 U.S. Dist. LEXIS 13695 at *10 (N.D.N.Y. 2013) ). However, the Commissioner's post hoc characterization of plaintiff's mental impairments as minor is undermined by the ALJ's step two finding that plaintiff's depression is a "severe" impairment. (Dkt. # 7 at 23). See Jones v. Colvin , 2015 WL 5126151 at *4, 2015 U.S. Dist. LEXIS 116298 at *10-*11 (W.D.N.Y. 2015) ("because the ALJ concluded that Plaintiff's depression was significant enough to constitute a severe impairment, his subsequent failure to obtain a medical assessment of the extent of that impairment from either a treating or consultative examiner quantifying Plaintiff's mental limitations rendered the record incomplete"). In any event, the leeway given to ALJs to make "common sense judgments" does not typically extend to the determination of mental limitations, which are by their very nature "highly complex and individualized." Nasci v. Colvin , 2017 WL 902135 at *9, 2017 U.S. Dist. LEXIS 31937 at *26 (N.D.N.Y. 2017) (because the determination of mental limitations is extremely complex, an ALJ's RFC finding relative to mental impairments cannot be rendered solely on common sense, but requires medical opinion evidence).
Because the ALJ's RFC finding was not supported by any medical opinions of record with respect to plaintiff's mental impairments, I find that the ALJ did not satisfy her duty to complete the record, and that her RFC finding was not supported by substantial evidence. Remand is therefore appropriate.
CONCLUSION
For the foregoing reasons, plaintiff's motion for judgment on the pleadings (Dkt. # 12) is granted, and the Commissioner's cross motion for judgment on the pleadings (Dkt. # 16) is denied. The Commissioner's decision that plaintiff, Brandice Lilley, was not disabled, is reversed, and the matter is remanded for further proceedings, including but not limited to the obtainment and consideration of medical opinion evidence relative to the limitations, if any, posed by plaintiff's mental impairments.
IT IS SO ORDERED.
