JEREMY D. PETERSON, Magistrate Judge.
This matter is before the court on claimant's request for judicial review of an unfavorable decision of the Acting Commissioner of the Social Security Administration regarding her application for a period of disability. At a hearing on July 2, 2019, we heard argument from the parties. We have reviewed the record, administrative transcript, briefs of the parties, and applicable law, and have considered arguments made at the hearing. For the reasons stated on the record at oral argument and in this order, we vacate the administrative decision of the Acting Commissioner of the Social Security Administration and remand this case for further proceedings before the Administrative Law Judge ("ALJ").
As explained in more detail at oral argument, we remand because the ALJ did not explain what weight she gave the opinion of Lance Portnoff, Ph.D., or explain why such weight was appropriate. Dr. Portnoff, a consulting examiner, made many findings about claimant's abilities, including: "The claimant's ability to deal with the stress encountered in a competitive work environment is moderate to markedly impaired due to MDD/PTSD/BIF." AR 1602. The ALJ summarized Dr. Portnoff's opinion but never said what she thought of it. In place of an evaluation of Dr. Portnoff's opinion and a justification therefor, the ALJ stated only:
AR 29. Notwithstanding the ALJ's description of certain portions of Dr. Portnoff's opinion as "somewhat vague and ambiguous"—a characterization with which one could certainly take issue—we are at a loss to determine whether or not the ALJ found Dr. Portnoff's opinion worthy of reliance. Without any statement of or explanation of the weight the ALJ placed on Dr. Portnoff's opinion, we cannot do our job as a reviewing court.
The error is not harmless. Dr. Portnoff's opinion raises questions about claimant's ability to handle the stress of a competitive work environment. Although the ALJ limited claimant to "simple, routine tasks" and "occasional interaction with coworkers and the public," these limitations do not necessarily address the stress-related issues identified by Dr. Portnoff. In the absence of any explanation from the ALJ, we are unable to say that Dr. Portnoff's opinion is not in conflict with ALJ's residual functional capacity determination.
The clerk of court is directed to enter judgment in favor of claimant Enjoli Nacole Beasley and against defendant Nancy A. Berryhill, the Acting Commissioner of Social Security, and to close this case.
