Summary
Blue Cross Blue Shield of Mississippi has published a fresh medical policy defining coverage criteria for Transanal Endoscopic Microsurgery (TEM). The policy establishes specific criteria for when TEM is considered medically necessary versus investigational, particularly for rectal adenomas and T1 rectal adenocarcinomas with strict anatomical and pathological requirements.
Action Required
Immediately: Billing team and providers must review current TEM cases to ensure they meet the new coverage criteria before submitting claims. For T1 rectal adenocarcinomas, verify documentation shows: location in middle/upper rectum, well/moderately differentiated pathology, no lymphadenopathy, and less than 1/3 circumferential involvement. Update prior authorization processes to include these specific criteria checks. Claims not meeting criteria will be denied as investigational.
