What 97605 covers
Code 97605 represents a session of negative-pressure wound therapy delivered with equipment that qualifies as durable medical equipment, when the combined surface area of treated wounds is 50 square centimeters or less. A sealed dressing connected to suction helps manage an open wound by drawing away fluid. Surgeons and wound-care clinicians commonly oversee this treatment in outpatient wound clinics and postoperative care. Dressing application, wound assessment, and patient or caregiver instruction for ongoing care are included.
Select the area tier using the combined surface area of wounds treated in the session, not the number of wounds; 97606 is used when the total exceeds 50 square centimeters. The equipment pathway also matters: use 97607 or 97608 for systems that do not require DME, applying the same area threshold. Document the treated wounds and their dimensions, equipment used, therapy provided, assessment, and instruction. CMS assigns work, practice-expense, and malpractice RVUs, with separate office and facility practice-expense inputs in the fee schedule.

How to choose
- 97606Negative pressure therapyDME, over 50 sq cm

- 97607Negative pressure therapyNonpowered, up to 50 cm²
- Both cover negative-pressure therapy for a combined wound area of 50 square centimeters or less. The distinction is whether the equipment requires DME.
- 97602Wound debridementNonselective method
- 97602 is for non-selective wound care, not negative-pressure therapy. Use 97605 when suction-based wound treatment with DME is provided.
97605 billing questions
How is the wound-area threshold determined?
Use the combined surface area of the wounds treated during the session. This code is for a total of 50 square centimeters or less; 97606 is for a larger total.
When should 97607 be used instead?
Use 97607 when the negative-pressure system does not require DME and the combined treated wound area is 50 square centimeters or less. The corresponding higher-area code is 97608.
Can the dressing application or wound assessment be billed separately?
Dressing application, wound assessment, and instruction for ongoing care are included in this service. Do not report those included elements as separate wound-care services.
Is the code reported once for each wound?
The area threshold is based on the combined wounds treated in the session, not a separate threshold for each wound. Document the individual wounds and their dimensions to support the total.
How does this differ from 97602?
97605 describes negative-pressure therapy using DME. Code 97602 describes non-selective wound care, such as routine cleansing or dressing care, rather than this suction-based treatment.
