Summary & Overview

CPT 97605: Negative Pressure Wound Therapy for Small Wounds

CPT code 97605 represents negative pressure wound therapy (NPWT) delivered with durable medical equipment for wounds with a total surface area of 50 square centimeters or less. This service controls subatmospheric pressure through a sealed dressing to remove exudate and infectious material and to promote wound healing. The code is commonly used in ambulatory and outpatient wound care settings and is an important tool in managing chronic and complex wounds nationally.

Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find an overview of payer coverage considerations and comparative benchmarks for utilization and reimbursement practices, a summary of clinical indications and typical sites of service, and guidance on associated service coding such as related NPWT codes. The publication also clarifies how 97605 differs from the related CPT code 97606, which is used for total wound surface areas greater than 50 square centimeters.

Billing Code Overview

CPT code 97605 describes negative pressure wound therapy (NPWT) using durable medical equipment for wounds with total surface area less than or equal to 50 square centimeters. The provider applies controlled subatmospheric pressure around the wound through a sealed dressing to remove fluids and infectious material and to aid healing.

Service type: Durable medical equipment–assisted negative pressure wound therapy with topical application(s), wound assessment, and instruction(s) for ongoing care
Typical site of service: Outpatient clinic, physician office, wound care center, or other ambulatory care settings where durable medical equipment can be applied and managed

Clinical & Coding Specifications

Clinical Context

A 68-year-old patient with peripheral vascular disease and diabetes presents to an outpatient wound care clinic for management of a non-healing lower extremity ulcer. The wound care nurse documents a 35 cm² full-thickness ulcer of the lower leg with moderate exudate and surrounding cellulitis absent systemic sepsis. The supervising physician (general surgeon) evaluates the wound, confirms suitability for negative pressure wound therapy (NPWT) using durable medical equipment, applies a sealed dressing, connects the portable pump, and programs subatmospheric pressure. The visit includes wound debridement as needed, assessment of wound size and exudate, dressing application with the NPWT device, and patient/caregiver instruction for device operation, alarm management, and outpatient device return. The patient is discharged with a plan for follow-up visits for dressing change and monitoring. Typical site of service is an outpatient wound care clinic, ambulatory surgical center, or physician office capable of providing durable medical equipment application. The service type is durable medical equipment–assisted negative pressure wound therapy for wounds with total surface area less than or equal to 50 square centimeters corresponding to a single session procedure documented under 97605.
