ORDER VACATING AND REMANDING DECISION OF THE ADMINISTRATIVE LAW JUDGE

WILLIAM J. MARTÍNEZ, District Judge.

This matter is before the Court on review of the Commissioner of Social Security's ("Defendant") decision to deny Plaintiff's application for supplemental security income benefits. Plaintiff Stephanie Yolanda Sandoval ("Plaintiff") filed an Opening Brief (ECF No. 14), Defendant filed a Response (ECF No. 17), and Plaintiff filed a Reply (ECF No. 18). After reviewing the briefs and administrative record filed with the Court, Defendant's decision to deny Plaintiff's application for supplemental security income benefits is vacated and remanded for further proceedings consistent with this Order.

I. BACKGROUND

Plaintiff was born on January 18, 1968. (Record ("R.") (ECF No. 9) at 196.) Plaintiff's medical records indicate she has been diagnosed with several mental and physical conditions, including vertigo, carpal tunnel syndrome, migraine headaches, degenerative disk disease, and depression. (R. at 491-94, 524, 546, 572.) Plaintif f alleges a disability onset date of January 1, 2008. (Id. at 196.) Plaintiff has past relevant work as a housekeeper and home health aide. (Id. at 27.)

Plaintiff's application for benefits was initially denied on May 19, 2011 by Administrative Law Judge Kathryn Burgchardt ("the ALJ"). (Id. at 88-101.) Plaintiff appealed to the Social Security Appeals Council, which remanded the case for additional proceedings. (Id. at 107.) The Appeals Council ordered the ALJ to evaluate Plaintiff's post-traumatic stress disorder and pain disorder, and to reassess Plaintiff's Residual Functional Capacity ("RFC"). (Id. at 107-109.) On December 13, 2012, the ALJ again denied Plaintiff's application for benefits. (Id. at 28.) The Appeals Council affirmed on May 15, 2014, which was the final agency action for purposes of the Court's review. (Id. at 1-3.)

In her December 13, 2012 decision, the ALJ found that Plaintiff was not under a disability, as defined in the Social Security Act, from the date of her application for benefits through the date of the decision. (Id. at 28.) The ALJ made the following findings of fact and conclusions of law in accordance with the Commissioner's five-step sequential evaluation process.1 At step one, the ALJ found that Plaintiff had not engaged in any substantial gainful activity since her application date of October 14, 2008. (Id. at 19.) At step two, the ALJ held that Plaintiff had the following severe impairments: degenerative disc disease, carpal tunnel syndrome, chronic pain, and depression. (Id. at 19.) At step three, the ALJ held that Plaintiff's impairments do not meet or equal the severity of the established listing of impairments under the governing regulations. (Id. at 20.) The ALJ then analyzed Plaintiff's RFC, concluding that Plaintiff:

(Id. at 22-23.) The ALJ then ruled at step four that Plaintiff was unable to perform any past relevant work. (Id. at 27.) However, considering the RFC assessment described above, along with Plaintiff's age, education, and work experience, at step five the ALJ determined that there are jobs that exist in significant numbers in the national economy that Plaintiff can perform. (Id.) Those jobs include call out operator, usher, and surveillance system monitor. (Id. at 28.)

On July 3, 2014, Plaintiff initiated this action challenging the ALJ's December 13, 2012 denial of benefits, which is now before the Court. (ECF No. 1.)

II. LEGAL STANDARD

The Court reviews the Commissioner's decision to determine whether substantial evidence in the record as a whole supports the factual findings and whether the correct legal standards were applied. Wall v. Astrue, 561 F.3d 1048, 1052 (10th Cir. 2009). Substantial evidence is such relevant evidence as a reasonable mind might accept as adequate to support a conclusion. Id. "It requires more than a scintilla, but less than a preponderance." Lax, 489 F.3d at 1084. Evidence is not substantial if it is overwhelmed by other evidence in the record. Grogan v. Barnhart, 399 F.3d 1257, 1261-62 (10th Cir. 2005). In reviewing the Commissioner's decision, the Court may neither reweigh the evidence nor substitute its judgment for that of the agency. Salazar v. Barnhart, 468 F.3d 615, 621 (10th Cir. 2006). "On the other hand, 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).

III. ANALYSIS

Plaintiff makes several arguments on appeal, including that the ALJ failed to review the opinions of two physicians, Dr. Donald Glasco and Dr. Karl Chambers. (ECF No. 14 at 34.) Dr. Glasco is a state agency reviewing psychiatrist, and Dr. Chambers is a state agency reviewing physician. (ECF No. 17 at 5.)

"An ALJ must evaluate every medical opinion in the record." Hamlin v. Barnhart, 365 F.3d 1208, 1215 (10th Cir. 2004); see also 20 C.F.R. § 404.1527(c) ("Regardless of its source, we will evaluate every medical opinion we receive."); Social Security Ruling ("SSR") 96-5P, 1996 WL 374183 at *3 (S.S.A. July 2, 1996) ("[O]pinions from any medical source on issues reserved to the Commissioner must never be ignored. The adjudicator is required to evaluate all evidence in the case record that may have a bearing on the determination or decision of disability, including opinions from medical sources about issues reserved to the Commissioner."). "Medical opinions are statements from physicians and psychologists or other acceptable medical sources that reflect judgments about the nature and severity of [claimant's] impairment(s) including [claimant's] symptoms, diagnosis and prognosis, what [claimant] can still do despite impairment(s), and [claimant's] physical or mental restrictions." 20 C.F.R. § 404.1527(a)(2). An ALJ's failure to discuss all of the medical opinions in the record is clear legal error. Victory v. Barnhart, 121 F. App'x 819, 825 (10th Cir. 2005).

Here, Defendant does not dispute that Dr. Glasco's opinion was part of the record in this case, and that "[i]nexplicably, the ALJ's decision makes no mention whatsoever of Dr. [Glasco's] report[] or opinions, and gave no reason for disregarding his opinion." Id.; (ECF No. 17 at 12-13.) This was error. Defendant nonetheless argues that Dr. Glasco's findings represented a "temporary inflation of Plaintiff's depression symptoms caused by her carpal tunnel syndrome and cervical problems" that would improve following Plaintiff's April 21, 2009 surgery. (ECF No. 17 at 13.) Defendant further argues that the ALJ fully explained her assessment of Plaintiff's "paragraph B" impairments, and Dr. Glasco gave no opinion on Plaintiff's mental limitations as they pertained to her RFC. (Id.)

The Court does not agree that the ALJ's failure to discuss Dr. Glasco's opinion constituted a harmless error. Dr. Glasco opined that Plaintiff had untreated major depressive disorder, along with moderate limitations in restriction of activities of daily living, moderate difficulties maintaining social functioning, and moderate difficulties maintaining concentration, persistence or pace. (R. at 572-79.) Dr. Glasco also noted that Plaintiff was assessed a GAF score of 45-50, which indicates "[s]erious symptoms . . . [or] serious impairment in social, occupational, or school functioning, such as inability to keep a job." Langley v. Barnhart, 373 F.3d 1116, 1123 n.3 (10th Cir. 2004).2 However, the ALJ found that the "evidence revealed at most mild limitation in activities of daily living and social functioning." (R. at 21.)

The "harmless error analysis . . . may be appropriate to supply a missing dispositive finding . . . where, based on material the ALJ did at least consider (just not properly), we could confidently say that no reasonable administrative factfinder, following the correct analysis, could have resolved the factual matter in any other way." Fischer-Ross v. Barnhart, 431 F.3d 729, 733-34 (10th Cir. 2005). Here, it is not apparent whether the ALJ considered Dr. Glasco's opinion at all. The Court thus cannot say that no reasonable factfinder could have resolved the matter differently given that Dr. Glasco's opinion suggests Plaintiff has social impairments and restrictions in activities of daily living greater than those contained in the ALJ's decision.3 While Defendant argues that Dr. Glasco clearly expressed that Plaintiff's symptoms were temporary given that Plaintiff's surgery would "markedly improve her major depression," it is not the Court's function to weigh the evidence. Oldham v. Astrue, 509 F.3d 1254, 1257 (10th Cir. 2007) ("To the extent that she is asking this court to reweigh the evidence, we cannot do so. . . . We review only the sufficiency of the evidence, not its weight.") (emphasis in original). Moreover, even though Dr. Glasco gave no opinion on Plaintiff's mental limitations as they pertained to her RFC does not mean that his opinions could be entirely ignored. Our precedent and the governing regulations are clear that the ALJ must consider every medical opinion in the record. Victory, 121 F. App'x at 825. The Court accordingly concludes that this matter should be remanded for the ALJ to consider Dr. Glasco's opinion.

For similar reasons, the Court concludes that the ALJ should consider Dr. Chambers' opinion. Dr. Chambers completed an RFC assessment that is consistent with the ALJ's RFC finding. (Compare R. at 22-23, with id. at 583-590.) While opinions on issues that are reserved to the Commissioner, such as a claimant's RFC, may not be considered "medical opinions," they must still be considered by the ALJ. SSR 96-5P, 1996 WL 374183 at *2 ("Nevertheless, our rules provide that adjudicators must always carefully consider medical source opinions about any issue, including opinions about issues that are reserved to the Commissioner."); see also Lackey v. Barnhart, 127 F. App'x 455, 457 (10th Cir. 2005). The Court acknowledges that the ALJ's failure to discuss Dr. Chambers' opinion is, most likely, a harmless error given the consistency between the ALJ's and Dr. Chambers' RFC findings. Fischer-Ross, 431 F.3d at 733-34. Nonetheless, having already concluded that the failure to discuss Dr. Glasco's opinion was not harmless error, the Court further concludes that it will not be unduly burdensome for the ALJ to also discuss Dr. Chambers' opinion, which will result in a fully developed record in this matter. The Court therefore concludes that the ALJ should consider Dr. Chambers' opinion on remand.

Because the Court vacates and remands based on the ALJ's failure to adequately weigh the aforementioned medical opinions, the Court need not address the other arguments raised by Plaintiff. See Madrid v. Barnhart, 447 F.3d 788, 792 (10th Cir. 2006) (where the ALJ's error affected the analysis as a whole, court declined to address other issues raised on appeal). The Court expresses no opinion as to Plaintiff's other arguments and neither party should take the Court's silence as tacit approval or disapproval of those arguments. The Court also does not intend by this opinion to suggest the result that should be reached on remand; rather, the Court encourages the parties and the ALJ to fully consider the evidence and all issues raised anew on remand. See Kepler v. Chater, 68 F.3d 387, 391-92 (10th Cir. 1995) ("We do not dictate any result [by remanding the case]. Our remand simply assures that the correct legal standards are invoked in reaching a decision based on the facts of the case.") (citation and quotation marks omitted).

IV. CONCLUSION

For the foregoing reasons, it is ORDERED that Defendant's final decision is VACATED and the case is REMANDED for further proceedings consistent with this Order.
