Summary
Aetna has issued a refreshed clinical policy (CPB 0856) effective 2026-01-12 that defines medical necessity criteria for selected embolization procedures. The policy clearly designates which embolization procedures are covered (with specific clinical criteria), which are experimental/investigational, and provides comprehensive CPT, HCPCS, and ICD-10 code guidance. Billing teams must align claim submission and prior authorization practices with these specific indications to prevent denials.
Action Required
By 2026-01-12: Billing team must implement the following changes: (1) Update prior authorization protocols in the billing system to require documented medical necessity for ALL embolization procedures using CPT codes 37241, 37242, 37243, 37244, 61624, 61626, and 75894. (2) Create a claims validation checklist matching each procedure to the covered indications listed in the policy (e.g., coil embolization for AVMs/aneurysms, gastric varices, GI bleeding, renal AML >6cm or with active bleeding, etc.). (3) Flag as AUTOMATIC DENIALS any claims for experimental/investigational procedures including: hemorrhoidal embolization, genicular artery embolization for osteoarthritis, middle meningeal artery embolization for chronic subdural hematoma, left gastric artery embolization for obesity, or endovascular lymphatic ablation. (4) Update encounter templates and prior auth forms to require providers document the specific clinical criterion being met (e.g., 'active GI bleeding' or 'renal AML size >6cm'). (5) Train billing and authorization staff on the 16 covered indications versus the 13 experimental indications to ensure accurate triage. Claims lacking documented medical necessity matching policy criteria will be denied by Aetna.
