CPT code 97606 represents negative pressure wound therapy (NPWT) delivered with durable medical equipment for wounds with total surface area greater than 50 square centimeters. The code captures application of controlled subatmospheric pressure via a sealed dressing to remove fluids and infectious material and promote wound healing. Nationally, NPWT codes matter because they reflect utilization of an evidence-based modality for complex wounds that often drives durable medical equipment use, care coordination, and site-of-service decisions across outpatient, home health, and facility settings.

Key payers covered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of the clinical intent of the code, typical sites of service, and the payer landscape relevant to billing and coverage. The publication summarizes common billing modifiers and related administrative considerations, outlines expected clinical contexts for use, and indicates where input data was not available.

This summary provides a concise reference for clinicians, billing managers, and policy analysts seeking to understand the role of CPT code 97606 in wound-care delivery and billing workflows, and what to expect when preparing claims or reviewing coverage policies at a national level.
