Summary
BCBSMS updated their policy on Extracranial Carotid Artery Stenting, defining specific criteria when carotid angioplasty with stenting is considered medically necessary versus investigational. The policy requires 50-99% stenosis, recent symptoms, and anatomic contraindications to endarterectomy for coverage, while declaring transcarotid artery revascularization investigational for all indications.
Action Required
Immediately: Review all pending and future carotid artery stenting claims to ensure they meet the specific medical necessity criteria (50-99% stenosis, symptoms within 120 days, anatomic contraindications to endarterectomy). Update prior authorization workflows to verify these requirements before submitting claims. Educate vascular surgery and interventional cardiology providers on the strict coverage criteria to prevent claim denials.
