By March 15, 2026: Billing team must update claim adjudication system to flag all claims containing the listed CPT codes (0232T, 0310T, 38230-38243, 61720, 61798-61799, 61863-61864, 61867-61868, 61880, 61885-61886, 64550, 64885-64886, 70553-70554, 76390, 78608-78609, 78813-78814, 78816, 81401, 81405, 83520, 83529, 90867-90870, 95836, 95970-95971, 95974, 95976-95977, 95983-95984, 38225) when linked to Huntington's disease diagnosis codes (ICD-10: G10 and related codes). Configure system to automatically deny these claims or route to prior authorization department with notation 'Experimental/Investigational per CPB 0614.' Immediately communicate to all providers and clinical staff that these interventions are non-covered for Huntington's disease treatment. Update billing software rules and encounter templates. Failure to enforce this policy will result in claim denials post-adjudication and potential payment clawbacks from Aetna for improperly processed claims. No grace period applies—policy is effective immediately upon date specified.
