MEMORANDUM OPINION AND ORDER

JAY C. GANDHI, Magistrate Judge.

Melinda F. Tocher ("Plaintiff") challenges the Social Security Commissioner's ("Defendant") decision denying her application for disability benefits. Specifically, Plaintiff contends that the ALJ erroneously gave great weight to the opinion of the medical expert, Dr. Sami A. Nafoosi, whose American Board of Internal Medicine certification had long been expired.2 (Joint Stip. at 4-6, 8-9.) The Court agrees with Plaintiff for the reasons stated below.

The Social Security regulations consider numerous factors relevant in weighing medical opinions. See generally 20 C.F.R. § 404.1527. Among them is the physician's specialization. Id. § 404.1527(c)(5).

Here, the ALJ gave the "greatest weight" to the testimony of the medical expert, Dr. Nafoosi. (AR at 34.) In support of this assessment, the ALJ explicitly referred to Dr. Nafoosi's expertise as an "internal medicine specialist," a characterization that was informed, at least in part, because Dr. Nafoosi was, in the ALJ's words, "[b]oard certified in internal medicine."3 (AR at 33-34.)

As it turns out, Dr. Nafoosi was not board certified — not since December 31, 2007, nearly three years before the administrative hearing. (Joint Stip. at 6; Exh. 1.) Thus, it would appear that the immense weight afforded to Dr. Nafoosi's opinion was unwarranted.

Defendant, however, argues that this error is insignificant, as medical experts do not need to be board certified in order to testify. (Joint Stip. at 7.) In fact, it is not uncommon, so Defendant reasons, for uncertified experts to be given greater weight than their certified counterparts. (Id.)

Even so, the Court may review only those reasons asserted by the ALJ in his decision. See Connett v. Barnhart, 340 F.3d 871, 874 (9th Cir. 2003). It is thus of no import here whether, as Defendant has demonstrated, the ALJ could have given Dr. Nafoosi greater weight for other reasons.4

Moreover, contrary to Defendant's assertions, harm is apparent here. "Although [board] certification is unnecessary, it is an added prestige upon which ALJs tend to rely." Bogosian, 2012 WL 1956861, at *3. And, in relying on such an indicia of prestige, the ALJ necessarily discounted other medical evidence, including the opinions of at least four examining physicians.5 See Carmickle v. Comm'r, Soc. Sec. Admin., 533 F.3d 1155, 1164 (9th Cir. 2008) (examining physicians are typically afforded great deference). It appears likely, then, that the ALJ's credibility determination may have been different had he known that Dr. Nafoosi was not actually board certified. A finding of error is therefore appropriate.

With error established, this Court has discretion to remand or reverse and award benefits. McAllister v. Sullivan, 888 F.2d 599, 603 (9th Cir. 1989). Where no useful purpose would be served by further proceedings, or where the record has been fully developed, it is appropriate to exercise this discretion to direct an immediate award of benefits. See Benecke v. Barnhart, 379 F.3d 587, 595-96 (9th Cir. 2004). But where there are outstanding issues that must be resolved before a determination can be made, or it is not clear from the record that the ALJ would be required to find plaintiff disabled if all the evidence were properly evaluated, remand is appropriate. See id. at 594.

Here, in light of the ALJ's error, the credibility of Dr. Nafoosi and other medical sources must be properly assessed. Therefore, on remand, the ALJ shall reevaluate their opinions and either credit them as true, or provide valid reasons for any portion that is rejected.

Based on the foregoing, IT IS ORDERED THAT judgment shall be entered REVERSING the decision of the Commissioner denying benefits and REMANDING the matter for further administrative action consistent with this decision.6
