August 17, 2015. A claimant with numerous impairments, including arthritis, was denied benefits in the ALJ hearing. The ALJ rejected the impairment of arthritis because the record lacked a formal diagnosis. We successfully argued that the ALJ did not fully develop the record with regard to all of the claimant’s impairments, namely, arthritis, even after the Social Security Administration’s examining expert stated the record was inadequate and needed to be fully developed. The District Court agreed with our argument, finding that the ALJ failed to properly evaluate all of the evidence and make the necessary inquiries to fully develop the record.
