What 86077 covers
A transfusion medicine physician or pathologist uses this service to interpret difficult red-cell compatibility findings, such as a complex crossmatch or an unexpected alloantibody that affects selection of compatible units. It may arise during pretransfusion testing for a patient with a prior transfusion, pregnancy, or known red-cell antibody. The physician assesses the serologic findings and their implications for transfusion support; routine testing performed by laboratory staff alone is not this physician service.
Report 86077 for the physician’s interpretive work, not for the laboratory’s technical performance of a crossmatch or antibody test. The record should support the complexity and clinical purpose of the interpretation, including relevant test findings and the physician’s conclusion or recommendation. CMS assigns physician work, practice expense, and malpractice RVUs; practice expense has separate office and facility values. The code is distinct from physician services for investigating a transfusion reaction or authorizing use of a blood product.
