Summary
Effective December 1, 2026, UnitedHealthcare is implementing a new unified vascular embolization policy and adding prior authorization requirements for CPT 37242 on commercial, Medicare Advantage, and most Community Plans. Site-of-service reviews for therapeutic vascular embolization (CPT 37242) are being discontinued, with reviews shifting to medical necessity only. This consolidates multiple existing policies into one for greater consistency.
Action Required
By November 30, 2026: Billing team must update all systems to require prior authorization for CPT 37242 for UnitedHealthcare commercial, Medicare Advantage, and applicable Community Plans. Remove any site-of-service review logic for CPT 37242 from billing workflows and replace with medical necessity review protocols. Update encounter templates and provider documentation requirements to support medical necessity justification. Identify all claims submitted for CPT 37242 under old site-of-service-only review processes and establish new submission procedures. Verify which UnitedHealthcare Community Plans in excluded states (ID, IN, KS, KY, NE, NJ, NM, NC, OH, PA, TN) are NOT affected pending state approval. Claims submitted without required prior authorization for CPT 37242 will be denied effective December 1, 2026.
