Summary
Aetna's updated CPB 0276 (reviewed 2026-09-10) establishes strict medical necessity criteria for cerebrovascular procedures including carotid artery stenting, endarterectomy, and intracranial interventions. Key requirements now include pre-procedure imaging confirmation (CTA/MRA), neurological assessment by certified professionals, documented discussion of all treatment alternatives, and exclusion of patients with disabling strokes (modified Rankin scale ≥3). Several procedures remain experimental/unproven, including asymptomatic vertebral artery stenting and prophylactic intracranial angioplasty.
Action Required
Immediately: Billing and clinical staff must implement new pre-authorization requirements for all cerebrovascular procedures (CPT 37215-37218, 61630-61642, 35301, 0075T-0076T). (1) Update billing software to require documentation of: stenosis degree (symptomatic ≥50% or asymptomatic ≥70% for carotid), completion of duplex ultrasound, CTA or MRA confirmation, and pre/post-procedure NIHSS assessment or neurologist evaluation. (2) Modify encounter forms and EMR templates to include mandatory physician attestation that all treatment options (CEA, CAS, TCAR, and medical therapy) were discussed with member and documented. (3) Configure system to DENY claims for patients with modified Rankin scale ≥3 undergoing carotid revascularization. (4) Flag CPT 61630, 61635, 61640-61642 as requiring dual diagnosis documentation (subarachnoid hemorrhage AND acute ischemia) or they will be denied. (5) Block claims for experimental procedures: asymptomatic vertebral artery stenting (0075T/0076T), drug-eluting stents for extracranial arteries, prophylactic intracranial angioplasty, and permanent common carotid embolic protection devices. (6) Train providers that intracranial angioplasty/stenting (CPT 61630, 61635) for atherosclerotic stenosis, prophylaxis, and emergent large artery occlusion remain unproven and non-covered. (7) Verify prior authorization is obtained BEFORE procedure scheduling; claims without complete medical necessity documentation will be denied.
