Summary
Aetna has issued a comprehensive medical policy (CPB 0505, effective 2026-08-03) defining coverage criteria for ambulatory assist devices including canes, crutches, walkers, and specialized variants. The policy establishes specific medical necessity requirements based on mobility-related activities of daily living (MRADL) and explicitly excludes certain device types (axillary crutches, sit-and-stand assistants, enclosed-frame walkers) as lacking established clinical value. Billing teams must ensure claims align with these specific device categories and documented medical necessity criteria.
Action Required
By August 3, 2026: Billing team must implement the following: (1) Update claim edits in billing software to enforce Aetna's specific device category requirements for ambulatory assist devices; (2) Ensure prior authorization systems can distinguish between covered devices (standard canes, crutches, walkers, heavy-duty walkers, wheeled walkers with glide brakes, pediatric crawlers, Mulholland Walkabout, Rifton/Pacer Gait Trainers, KidWalk, TAOS, standers) and non-covered devices (axillary/articulated/spring-assisted crutches, sit-and-stand walking assistants, standard strollers, enclosed-frame walkers, enhancement accessories like baskets/cup holders); (3) Create or update encounter templates requiring providers to document that patient meets ALL medical necessity criteria: (a) has mobility limitation significantly impairing MRADL (toileting, feeding, dressing, grooming, bathing), (b) can safely use the device, and (c) device can sufficiently resolve functional deficit; (4) Implement automatic denial rules for non-covered device types with standard denial messaging; (5) Train billing and authorization staff on device-specific requirements (e.g., heavy-duty walkers require documentation of weight >300 lbs, specialized braking walkers require documentation of severe neurological disorder or one-hand-use condition). Failure to implement these edits will result in claim denials and rework.
