Neg prs wnd thr ndme<=50sqcm
CPT 97607 covers negative pressure wound therapy (vacuum-assisted wound closure) for wounds measuring 50 square centimeters or smaller. This therapy uses controlled suction to promote healing in chronic or difficult-to-heal wounds.

Billing tips
Always measure and document wound surface area in square centimeters using length × width method before each NPWT application
Impact: Prevents downcoding or denials; incorrect size documentation can result in $302.76 underpayment if downcoded to a lower-level service or complete denial
Bill in non-facility settings (office, wound care center) rather than facility settings when possible to capture the $323.14 rate versus $20.38
Impact: Increases reimbursement by $302.76 per treatment (1,485% higher payment) when proper setting is utilized
Document medical necessity including failed conservative treatments, infection control measures, and wound progression photographs with measurements
Impact: Reduces denial rate by approximately 60-70% based on payer audits; incomplete medical necessity documentation is the leading cause of claim denials
Separately bill for NPWT supplies and equipment using HCPCS codes (A6550, E2402) in addition to CPT 97607 for the professional service
Impact: Captures additional $150-$300 per week in supply reimbursement that is not included in the CPT 97607 professional service fee
Verify prior authorization requirements before initiating NPWT, as many commercial payers require pre-approval for coverage
Impact: Prevents 100% payment denials; retroactive authorization denials average $1,500-$2,000 per patient episode when multiple treatments are rendered
Use 97608 (>50 sq cm) instead of 97607 when wound exceeds 50 square centimeters to ensure accurate coding and prevent audit risk
Impact: Prevents upcoding audits and potential recoupment; using correct code based on wound size avoids compliance issues and potential False Claims Act exposure
Common denials
Medical necessity not established - lack of documentation showing failure of conventional wound therapy before NPWT initiation
How to appeal: Submit comprehensive wound care timeline showing minimum 30 days of failed conservative treatment including debridement, moisture-retentive dressings, offloading, and infection management; include weekly wound measurements demonstrating lack of progress or deterioration; attach clinical practice guidelines supporting NPWT initiation criteria
Incorrect wound size documentation or measurement method not specified, leading to inability to verify code selection
How to appeal: Provide detailed operative/procedure note with wound measurements using length × width formula in centimeters, photographic documentation with calibrated measuring device visible, and wound tracing if available; clarify measurement was performed with wound edges approximated to determine actual surface area
Frequency limitation exceeded - payer policy limits NPWT applications to specific intervals (typically 2-3 times per week)
How to appeal: Submit clinical documentation justifying increased frequency due to high exudate volume, infection, or compromised seal integrity; provide manufacturer recommendations for dressing change frequency; include wound culture results if infection present; request peer-to-peer review with medical director
Place of service discrepancy - facility modifier or POS code conflicts with non-facility rate claim
How to appeal: Verify and correct place of service code to match actual treatment location; submit facility documentation, registration records, or photographs proving service location; if truly rendered in non-facility setting, provide corrected claim with POS 11 and explanation of billing error
Frequently asked questions
What is the Medicare reimbursement rate for CPT 97607 in 2025?
The 2025 Medicare national average reimbursement for CPT 97607 is $323.14 in non-facility settings and $20.38 in facility settings. The substantial difference reflects practice expense costs including NPWT equipment that are covered in the non-facility rate but provided by the facility in hospital settings.
How do you measure wound size to determine whether to use 97607 or 97608?
Measure the wound's greatest length and greatest width in centimeters, then multiply to get surface area. Use CPT 97607 for wounds 50 square centimeters or smaller (e.g., 5cm × 10cm = 50 sq cm). Use CPT 97608 for wounds greater than 50 square centimeters. Document the measurement method and measurements in the medical record with each application.
Can CPT 97607 be billed on the same day as wound debridement codes?
Yes, CPT 97607 can be billed with debridement codes (11042-11047, 97597-97598) when performed on the same wound, as debridement is often necessary before NPWT application. Use modifier 59 or XS if needed to indicate distinct procedural services. Ensure documentation clearly shows both procedures were medically necessary and performed.
How often can CPT 97607 be billed for the same patient?
Frequency depends on payer policy and medical necessity. Medicare does not have a specific frequency limit for 97607, but typical NPWT protocols involve dressing changes 2-3 times per week. Commercial payers may have specific frequency limitations in their medical policies. Document clinical rationale for dressing change frequency based on exudate level, seal integrity, and wound response.
What documentation is required to support medical necessity for CPT 97607?
Documentation must include: wound etiology and characteristics, failed conservative treatments (typically 30 days of standard wound care), wound measurements in square centimeters, photographs when possible, absence of contraindications (untreated osteomyelitis, malignancy in wound, exposed vessels or organs), and treatment goals. Document why NPWT is appropriate versus standard wound care.
Who can perform and bill for CPT 97607 services?
CPT 97607 can be performed and billed by physicians, physical therapists, physician assistants, nurse practitioners, and certified wound care specialists depending on state scope of practice laws and payer policies. Physical therapists must use modifier GN for therapy services. Some payers require physician supervision or certification in wound care management.
Is prior authorization required for CPT 97607?
Prior authorization requirements vary by payer. Medicare typically does not require prior authorization for CPT 97607, but many Medicare Advantage and commercial plans do require pre-approval for NPWT services due to high cost. Always verify authorization requirements before initiating treatment to avoid denials. Authorization is typically needed for both the professional service (97607) and NPWT equipment/supplies.
