Federal Old-Age, Survivors and Disability Insurance and Supplemental Security Income for the Aged, Blind, and Disabled; Medical and Other Evidence of Your Impairment(s) and Definition of Medical Consultant
We are revising the Social Security and Supplemental Security Income (SSI) disability regulations regarding sources of evidence for establishing the existence of a medically determinable impairment under title II and title XVI of the Social Security Act (the Act). We are doing this to clarify and expand the list of acceptable medical sources and to revise the definition of the term "medical consultant" to include additional acceptable medical sources.
