Summary
Humana Medicare Advantage has issued a comprehensive coverage policy (effective 10/01/2026) for elective aortic and iliac artery aneurysm repair procedures, establishing specific medical necessity criteria for open surgical repair (OAR), endovascular repair (EVAR), and fenestrated endovascular repair (FEVAR). The policy defines diameter thresholds, growth rates, and clinical conditions that qualify for coverage, with distinct requirements for abdominal aortic aneurysms (AAA), thoracic aortic aneurysms (TAA), and iliac artery aneurysms (IAA).
Action Required
By September 1, 2026: (1) Billing team must update authorization system to enforce new medical necessity criteria for CPT codes 34830-34832 (open AAA repair), 34701-34706 (EVAR), and 34841 (FEVAR). (2) Create pre-authorization checklist requiring documentation of: aneurysm diameter measurements with imaging dates, growth rate calculations (if applicable), patient sex/stature, and clinical indicators (dissection, dissection type, penetrating ulcer specifics, etc.). (3) Update encounter templates and prior auth forms to require providers to document which coverage criterion is being met. (4) Configure system to auto-deny claims lacking required diameter/growth documentation or failing to meet stated thresholds. (5) Train authorization staff on distinction between OAR vs. EVAR approval pathways and shared decision-making scenarios. Failure to implement prior authorization checks will result in claim denials for procedures not meeting policy criteria.
