CPT 97608: Negative Pressure Wound Therapy for Wounds >50 cm2

CPT code 97608 denotes negative pressure wound therapy (NPWT) using disposable, non‑durable equipment for wounds with a total surface area greater than 50 cm². This procedure is used to remove exudate and infectious material and to promote healing in slow‑healing or nonhealing wounds such as decubitus ulcers and large open wounds. Nationally, NPWT is an important tool in wound management because it can reduce healing time and the risk of complications for complex wounds, and its coding distinguishes sessions that use disposable systems for larger wound areas.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise overview of the clinical context for CPT code 97608, how it differs from related NPWT codes for smaller wounds or durable equipment, and practical billing considerations. The publication outlines common payer coverage patterns, coding comparisons to related codes 97605, 97606, and 97607, and typical sites of service for delivery of NPWT.

This summary equips clinicians, billing staff, and policy analysts with the clinical framing and coding distinctions needed to classify NPWT sessions for larger wounds correctly and to understand the payer landscape and documentation expectations relevant to CPT code 97608.

Billing Code Overview

CPT code 97608 describes negative pressure wound therapy (NPWT) using disposable, non‑durable equipment for wounds with a total surface area greater than 50 cm². The procedure involves applying controlled subatmospheric pressure around a wound through a sealed dressing to remove fluids and infectious material and to aid wound healing.

Service type: Negative pressure wound therapy using disposable, non‑durable medical equipment, topical applications, wound assessment, and instructions for ongoing care.

Typical site of service: Outpatient wound care clinics, hospital outpatient departments, home health visits, and other ambulatory settings where wound management is provided, depending on clinical need and payer coverage.

National Reimbursement Benchmarks

Across payers, Medicare mean rates for CPT 97608 sit noticeably higher than BUCA’s commercial average: Medicare mean $415.30 versus BUCA mean $243.70, reflecting Medicare’s concentration at the upper-middle of locality rates (median $405, P25 $377, P75 $435) compared with BUCA’s broader commercial center (P50 $180.50, P25 $99.20, P75 $351.90). This positions Medicare nearer to the top of the national distribution while BUCA aligns with many commercial payers’ mid-range means.

Dispersion (P75 minus P25) highlights variability across payers: Blue Cross Blue Shield shows a range of $240.00 ($381.20 - $144.20), UnitedHealth Group $288.00 ($343.90 - $55.90), Cigna $346.70 ($384.60 - $38.90), BUCA $252.70 ($351.90 - $99.20), and Aetna $189.70 ($210.00 - $23.00). Cigna has the widest interquartile spread, while Aetna is the tightest among these payers.

Clinical & Coding Specifications

Clinical Context

A 72-year-old male with chronic venous insufficiency and a non-healing ulcer of the lower leg presents to an outpatient wound-care clinic for evaluation. The wound measures 8 cm by 7 cm (56 cm2), has moderate serous drainage, and shows slough without signs of systemic sepsis. The clinician performs wound assessment, documents wound size, depth, surrounding skin condition, and reviews prior treatments (sharp debridement, dressings, compression). Given the wound surface area greater than 50 cm2 and slow healing over several weeks despite local care, the provider initiates negative pressure wound therapy (NPWT) using a portable system and applies a sealed dressing to create controlled subatmospheric pressure around the wound. The visit includes application of the NPWT dressing, connection to the device, instruction to patient/caregiver on device care and alarm management, and documentation of dressing components, wound assessment, and plan for follow-up in 48–72 hours for dressing check and potential dressing change. Typical sites of service for this procedure are outpatient wound-care centers, hospital outpatient departments, skilled nursing facilities, long-term acute care hospitals, and home health settings where the facility or clinician can apply and manage NPWT for wounds larger than 50 cm2.
