Documentation requirements
What must appear in the operative or office note to support the claim.
Source · Editorial brief grounded in 7 cited references ↓
- Measured wound dimensions for every wound treated, with total combined surface area explicitly stated in cm² (e.g., 'Total wound area = 82 cm²')
- Confirmation that a disposable, single-use NPWT device was used — not durable/reusable equipment
- Clinical rationale for NPWT: why negative pressure is medically necessary for this wound at this session
- Wound assessment findings: wound bed appearance, exudate type and volume, wound margins, and any signs of infection
- Documentation that the wound site is open — 97605–97608 are not reportable over closed incisions
- Physician order or prescription for NPWT on file
- Patient or caregiver instructions provided, noted in the session record

What this code covers
Source · Editorial summary grounded in 7 cited references ↓
CPT 97608 covers one session of disposable (non-durable) NPWT applied to wounds totaling more than 50 sq cm. The code bundles everything delivered in that session: device application and activation, all dressing materials, tubing, interface layers, wound assessment, exudate management, and patient or caregiver instructions. Bill nothing additional for supplies or device components — unbundling any of those is an NCCI violation.
The 50 sq cm threshold is a combined total, not per-wound. If a patient has three wounds measuring 10, 20, and 25 sq cm treated in the same session, add them (55 sq cm) and bill 97608 once. Never split wounds across 97607 and 97608 in the same session. The code is also device-type-specific: 97608 requires a disposable, single-use system. Durable (reusable) NPWT equipment belongs under 97605–97606 regardless of wound size.
The global period is XXX — no global surgical package applies, so each session is billed independently. Same-day debridement (11042–11047) may be separately payable, but MAC and commercial payer policies differ; document that debridement was a distinct service completed before NPWT initiation, and apply modifier 59 only when payer policy supports it. Some payers require prior authorization for disposable NPWT — verify before the first session.

Common denial reasons
The recurring reasons claims for CPT 97608 get rejected.
Source · Editorial brief grounded in CMS NCCI edits, AAOS coding appeals, and cited references ↓
- Wound area not documented or not stated as exceeding 50 sq cm — payers will default to 97607 or deny outright
- Disposable vs. durable device not specified — auditors cannot confirm correct code selection without this distinction
- Unbundling: billing separate supply or device HCPCS codes alongside 97608 when those items are already bundled
- Multiple wounds billed as separate 97607/97608 units instead of combining wound areas into a single code per session
- Missing prior authorization for payers that require it before disposable NPWT initiation
- 97608 billed over a closed surgical wound — code requires an open wound site

Mira AI Scribe
Mira's AI scribe captures wound dimensions for each site treated, calculates combined total surface area, names the device type (disposable single-use), records the wound bed assessment and exudate description, and logs that patient instructions were provided. This prevents the two most common 97608 denials: missing area documentation and failure to specify disposable versus durable equipment.
