CPT Code 97607 & 97608: Negative Pressure Wound Therapy (NPWT) Billing & Guidelines

Introduction

CPT codes 97607 and 97608 are medical billing codes used for negative pressure wound therapy (NPWT), a technique widely employed in wound management. These codes specifically cover NPWT when provided using a disposable, non-durable device. Healthcare providers must understand the significance of these codes to ensure accurate billing, maximize reimbursement, and improve patient care.

This article delves into the details of CPT codes 97607 and 97608, their applications, billing procedures, reimbursement policies, and common pitfalls to avoid.

What are CPT Codes 97607 and 97608?

Definition and Purpose

CPT 97607 and 97608 refer to negative pressure wound therapy (NPWT) services using a disposable, non-durable device, as opposed to traditional durable NPWT systems.

• CPT 97607: NPWT (wound vacuum therapy) for wounds less than 50 cm² in size.
• CPT 97608: NPWT for wounds greater than 50 cm² in size.

These codes are used when healthcare providers apply a single-use, non-durable wound vacuum system to facilitate wound healing by drawing out fluids, reducing infection risk, and enhancing tissue perfusion.

Importance of CPT Codes 97607 and 97608 in Medical Billing and Coding

• Ensure accurate documentation and reimbursement for NPWT services.
• Help differentiate between wound sizes, ensuring precise billing.
• Assist in distinguishing between durable and disposable NPWT devices.
• Facilitate proper claim submission to Medicare, Medicaid, and private insurers.

Common Medical Conditions Treated with CPT Codes 97607 and 97608

NPWT is primarily used in wound management for both acute and chronic wounds. These include:

• Diabetic ulcers – Helps promote healing in patients with chronic foot ulcers.

• Surgical wounds – Helps in post-operative wound management by reducing the risk of infections.
• Traumatic wounds – Aids in treating lacerations, burns, and degloving injuries.
• Venous stasis ulcers – Improves wound healing by promoting tissue growth.

NPWT significantly improves wound healing outcomes, making it a critical component of wound care management.

Understanding the distinction between CPT 97607 (for wounds <50 cm²) and CPT 97608 (for wounds >50 cm²) is essential for accurate billing. Proper documentation, including wound measurements, medical necessity justification, and treatment details, is crucial for avoiding claim denials. Additionally, staying up-to-date with Medicare, Medicaid, and private insurance policies can help maximize reimbursement.

By following best practices such as double-checking wound size, using correct modifiers, and maintaining thorough documentation, healthcare providers can reduce claim denials and improve revenue cycle management. Utilizing related CPT codes correctly, such as debridement and skin grafting codes, can further streamline the billing process and ensure complete reimbursement for wound care services.

Furthermore, avoiding common billing mistakes—such as incorrect wound size reporting, missing documentation, or improper modifier use—can prevent unnecessary claim rejections and audits. Regular staff training, audits, and compliance checks are crucial in maintaining accurate coding and billing practices.
