Billing and Coding: Thoracic Aortography and Carotid, Vertebral, and Subclavian Angiography

Coverage for thoracic aortography and carotid/vertebral/subclavian angiography is determined by LCD L35035 and requires documentation of medical necessity per that LCD. Coding limitations include not reporting certain CPT code pairs together for ipsilateral angiography (e.g., 36222/23/24 or 36225/26) and typically not reporting 75600/75605 with 36221–36227; follow NCCI edits (Chapters V and IX) and use appropriate modifiers when billing non-covered services.
