CPT 97606 NPWT Reimbursement & Policy | OpenPayer

Summary & Overview

CPT 97606: Negative Pressure Wound Therapy for Large Wounds

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.

Billing Code Overview

CPT code 97606 describes the application of controlled subatmospheric pressure therapy using durable medical equipment applied around a wound through a sealed dressing to remove fluids and infectious material and to aid healing for wounds with a total surface area greater than 50 square centimeters.

Service type: Negative pressure wound therapy (NPWT) using durable medical equipment
Typical site of service: Outpatient wound care clinics, hospital outpatient departments, long-term care facilities, and home health settings where durable medical equipment can be applied and managed

Clinical & Coding Specifications

Clinical Context

A 67-year-old male with poorly controlled type 2 diabetes and a chronic full-thickness left lower extremity wound measuring approximately 75 square centimeters presents to an outpatient wound clinic for ongoing management. The wound shows moderate serosanguinous drainage, macerated edges, and slough on the base despite standard moist wound care and debridement. The provider elects to apply negative pressure wound therapy (NPWT) using a durable NPWT device configured for continuous subatmospheric pressure, secured with a sealed dressing and tubing to a canister-based suction unit.

The clinical workflow includes: a focused wound assessment (size, depth, exudate, signs of infection), measurement and photography, appropriate wound bed preparation (sharp or enzymatic debridement if indicated), application of a sterile NPWT foam or gauze dressing cut to wound dimensions, placement of an occlusive adhesive drape to create a seal, connection to the NPWT device, verification of negative pressure function, patient/caregiver education on device alarms and canister management, and documentation of wound measurements, rationale for NPWT, device settings, and planned follow-up. Dressing change frequency and device duration are determined by wound response and payer policy. This scenario corresponds to NPWT applied to a wound with total surface area greater than 50 square centimeters, consistent with billing using 97606 for the application of durable subatmospheric pressure therapy in the outpatient setting.
