This policy provides coverage determination guidance for jurisdictions without existing local coverage determinations.
Action Required
By May 4, 2026: Billing team must ensure proper documentation of medical necessity for CPT 75635 (CTA abdominal aorta) claims for Humana Medicare Advantage patients.
