The College of American Pathology (CAP) has objected to four policies by BlueCross and BlueShield of Mississippi (BCBSMS) that adversely affect billing the professional component (PC) of clinical pathology services and certain immunohistochemistry (IHC) services and special stains. The policies contain a component billing coding policy under which the PC of clinical pathology services is not allowed when such services are rendered on an inpatient basis and three "medical policies" in the immunohistochemistry space. All four policies were to be effective July 1, 2016. A temporary restraining order secured by pathologists in Mississippi on July 1 prevented the policies from going into effect. The CAP has actively engaged with the Mississippi Association of Pathologists and transmitted a letter to BCBSMS expressing its objections and asking BCBSMS not to implement the policies.
