Evidence of Disability

The Railroad Retirement Board (RRB) amends its regulations to designate additional acceptable medical sources in disability claims under the Railroad Retirement Act. This change recognizes the evolution of how medical care and treatment are delivered and aligns the RRB's acceptable medical sources with recently amended regulations of the Social Security Administration (SSA). Additionally, the changes clarify existing RRB policy regarding how evidence from medical sources, other than those designated as acceptable medical sources, will be evaluated.
