Summary
Aetna has updated its Negative Pressure Wound Therapy (NPWT) medical policy (CPB 0334) effective June 8, 2026. The policy establishes strict medical necessity criteria for NPWT coverage, including mandatory prior completion of comprehensive wound care programs, specific eligibility conditions (Stage III/IV pressure ulcers, neuropathic ulcers, venous insufficiency ulcers, or surgical/traumatic wounds), documented contraindications that deny coverage, and a maximum 12-week treatment duration (30-day increments) with specific continuation and discontinuation requirements. Key supply limits include 15 dressing kits per wound per month and 10 canister sets per month unless documentation supports higher utilization.
Action Required
By June 8, 2026: Billing team must implement prior authorization requirements for all NPWT claims. (1) Update billing software to automatically flag NPWT requests for prior auth review before claim submission. (2) Providers must document all mandatory criteria in encounter notes, including: comprehensive wound evaluation with measurements, dressing application methods, debridement documentation, nutritional assessment, and underlying condition management. (3) Create NPWT prior auth checklist in EMR requiring: eligible condition confirmation (Stage III/IV pressure ulcer, neuropathic ulcer, venous insufficiency ulcer, or surgical/traumatic wound), completion of prerequisite treatments (support surfaces, compression therapy, diabetic management programs), and contraindication screening. (4) Implement claim submission rules: deny or hold claims without documented progressive wound healing every 30 days; enforce 15 dressing kit and 10 canister monthly limits unless high-volume exudate (>90 ml/day) is documented; enforce absolute denial for exposed anastomotic sites, nerves, organs, active bleeding, malignancy, necrotic tissue with eschar, unexplored fistulas, osteomyelitis, contaminated wounds, exposed bone, or infected wounds; enforce 12-week maximum duration (120 days) with automatic denial at 4-month mark unless individual consideration requested with additional documentation. (5) Notify all providers that claims will be denied without prior authorization and proper documentation; continuation beyond 30 days requires evidence of progressive healing with quantitative wound measurements (length, width, depth) documented at least every 2 weeks, or claims will be rejected.
