CPT code 97607 – Disposable NPWT System (≤ 50 sq cm)

Negative pressure wound therapy (NPWT) has undergone a remarkable evolution in the past decade. Once reserved mainly for acute care hospitals, it has now become a standard option in outpatient clinics, skilled nursing facilities, and even home health settings. This expansion is largely due to the development of compact, disposable NPWT systems that simplify treatment without compromising effectiveness.

As clinical practice shifted, the coding framework needed to adapt as well with the introduction of CPT codes 97607 and 97608. For clinicians and billing teams, accurately using CPT 97607 is important for reimbursement, documentation quality, and compliance. This guide covers: what CPT 97607 includes, how disposable NPWT differs from traditional systems, when 97607 should be used, documentation essentials, billing and payer considerations, common denial risks, and practical tips with sample documentation.

What Does CPT 97607 Mean?

Let’s start with the official concept behind the code.

CPT 97607 describes:
Negative pressure wound therapy (e.g., vacuum-assisted drainage collection), using disposable, non-durable equipment, including the exudate collection system, wound care applications, wound assessment, and patient instructions, per session, for total wound surface area ≤ 50 sq cm.

In simpler terms:

• It’s NPWT using a disposable system, not a traditional electric pump.
• It includes all supplies & device components used in that session.
• It’s billed per treatment session, not per day.
• It applies when all treated wounds combined are ≤ 50 cm².
• When > 50 cm², you move to CPT 97608 instead.

Many brands fall under this category (single use or mechanical NPWT systems), but the code is not brand specific; it can be used for any disposable NPWT device that meets the same specifications.

Disposable NPWT vs Traditional (Durable) NPWT

To really use 97607 correctly, it helps to understand how disposable NPWT is different from durable NPWT.

1. Traditional (durable) NPWT

Durable NPWT systems:

• Use a powered pump (electrical device)
• Are billed using different codes: 97605–97606 for professional services, and E2402 / A6550 / A7000 etc. for equipment and supplies, depending on setting and payer.
• Typically require separate or additional supply and device billing

2. Disposable NPWT

Disposable or single-use NPWT systems:

• Often small, lightweight, and portable
• May be mechanical (non-powered) or battery-powered
• Designed for short-term or specific wound indications
• Billed using CPT 97607 (≤ 50 cm²) or 97608 (> 50 cm²)
• Do not require separate HCPCS codes for the device or supplies; 97607/97608 already include them in the service payment.

This distinction is not just academic; choosing the wrong code set (durable vs disposable) is a common reason for denials and audit findings.

When Should You Use CPT 97607?

Once you’ve confirmed it’s a disposable NPWT system, ask three key questions:

• Is the total wound surface area ≤ 50 cm²?

If yes → 97607

If no → consider 9760

• Is NPWT actually being applied and managed during this visit?

The clinician must provide hands-on active wound care, including dressing changes, assessments, and management of the system.

• Is the service separate and distinct from other visits/procedures that day?

NPWT should be clinically necessary and properly documented as such.

Typical clinical use cases

• Diabetic foot ulcers
• Venous or arterial leg ulcers
• Pressure injuries (stage 3–4, or deep tissue injuries, depending on policy)
• Post-surgical wound dehiscence
• Traumatic wounds or skin graft sites

Disposable NPWT can be especially useful in home health, outpatient wound clinics, and SNFs, where a compact, low-maintenance device can simplify logistics and improve patient adherence.

What Exactly Is Included in 97607?

This is where coders and clinicians often get tripped up.
By definition, CPT 97607 bundles multiple elements into a single code, including:

Use of a disposable NPWT device, including:

• Canister or integrated collection system
• Dressings, tubing, and connectors
• Topical applications, if part of the NPWT session (e.g., saline-moistened gauze, contact layers)
• Wound assessment (type, size, depth, drainage, tissue types, signs of infection)
• Exudate management (managing the fluid collected by the system)
• Patient/caregiver instructions on device management and ongoing care

Because 97607 is so inclusive, you generally should not bill separate codes for supplies or routine wound dressings done as part of the NPWT session. This “all-in-one” nature is one of the major differences from older NPWT coding approaches.

How Revenue Codes Apply in Different Care Settings

Medicare guidance provides important clues on how 97607 should be billed in home health and other institutional settings.

1 Home Health Agencies (HHA)

Under home health, disposable NPWT is billed using CPT 97607 or 97608, reported with revenue codes that reflect which clinician performed the service:

• 0559 – Skilled nurse
• 042x – Physical therapy
• 043x – Occupational therapy

When billed under PT or OT revenue codes (042x/043x), CMS specifically notes that the therapy plan-of-care modifiers (GO/GP) should not be used for disposable NPWT.

2 Outpatient hospital or wound clinic

For hospital outpatient departments or wound centers, 97607 is typically reported on the UB-04 (CMS-1450) form with the appropriate revenue code and charge for the NPWT session. Some payers request that the brand name of the device be listed in the narrative or remarks field for clarity.

Payer-specific policies can vary, so always cross-check your local MAC or commercial payer’s NPWT policy.

Surface Area Rules: 97607 vs 97608

A frequent point of confusion is how to apply the surface area threshold across multiple wounds.
For disposable NPWT, the total wound area across all wounds treated in that session is summed:

• If combined ≤ 50 cm² → 97607
• If combined > 50 cm² → 97608

So if a patient has:

• Wound A: 20 cm²
• Wound B: 25 cm²

Total = 45 cm² → 97607 is correct.
You don’t bill separately per wound; you bill once per session with the appropriate code based on total area.

Documentation Requirements for CPT 97607

Because 97607 bundles devices, supplies, and professional work, strong documentation is critical. Good notes support both medical necessity and accurate code selection.

Here’s what you should aim to include:

1. Wound details

• Location (e.g., right plantar foot, sacrum, left lateral leg)
• Type/etiology (diabetic ulcer, venous stasis ulcer, pressure injury, traumatic wound, post-surgical)
• Measurements (length, width, depth) to calculate surface area (L × W)
• Total combined surface area when more than one wound is treated
• Description of tissue (granulation, slough, eschar)
• Exudate (amount, color, odor)
• Signs of infection or ischemia if present

2. NPWT details

• Name/type of disposable NPWT system (e.g., single-use mechanical system)
• Pressure settings (e.g., –80 mmHg, continuous or intermittent)
• Type of dressing placed under the device (foam, gauze, interface layers)
• Whether the dressing was initiated, changed, or discontinued
• Any complications or patient intolerance

3. Clinical decision-making

• Why NPWT is clinically indicated (e.g., failure of conventional therapy, heavy exudate, depth, risk of dehiscence)
• Response to therapy over time (improvement in size, granulation, exudate)
• Coordination with other therapies: offloading, compression, glucose control, antibiotics, etc.

4. Patient or caregiver education

• Use and troubleshooting of the device
• Instructions re: alarms, leaks, what to do if device stops
• When to call the provider or seek urgent care

Example documentation snippet

“Initiated disposable NPWT system to right plantar diabetic foot ulcer. Wound measures 2.5 cm × 3.0 cm (7.5 cm²), depth 0.4 cm, with 70% beefy granulation tissue and 30% slough. Moderate serosanguineous exudate, no odor, no surrounding cellulitis. Applied non-adherent interface, cut-to-fit foam, and occlusive drape, then connected to single-use NPWT device at –80 mmHg continuous. Patients instructed on device management, leak alarms, and signs of infection. Total wound surface area ≤ 50 cm²; CPT 97607 applies.”

This level of detail makes the code selection obvious and defensible.

Billing Tips and Common Denial Traps

Even when the clinical care is excellent, claims for 97607 can go sideways. Here are some problems you can proactively avoid.

1. Using the wrong code set (durable vs disposable)

One of the biggest traps is using 97605–97606 (durable NPWT codes) when you’re actually using a disposable/single-use device, or vice versa. Make sure your team knows which devices are billed under which code family.

Rule of thumb:

• Device rented/owned, powered pump → durable NPWT; use 97605/97606 + applicable HCPCS
• Single-use/disposable device → 97607/97608 only, no separate supply/device HCPCS

2. Double billing supplies

Because 97607 includes the disposable NPWT system and supplies, billing additional supply codes can trigger denials or recoupments for “unbundling.”

3. Inconsistent or missing surface area documentation

If the documentation doesn’t clearly support wound measurements, auditors may question both medical necessity and the choice of 97607 vs 97608. Record:

• Length and width of each wound
• Calculated area for each
• Total combined area

4. Lack of clear NPWT service description

Simply stating “NPWT performed” is not enough. Payers expect to see:

• That NPWT was actually managed during that specific session
• Clinically meaningful wound assessment and decision-making
• Evidence the provider or skilled clinician was directly involved

5. Not checking payer-specific policies

Commercial payers may:

• Require prior authorization for NPWT
• Limit NPWT use to certain wound types or stages
• Specify maximum number of sessions per episode or per wound

Always cross-check payer NPWT policies and keep an updated internal cheat sheet.

Practical Workflow Tips for Teams

To make CPT 97607 coding smooth and consistent, consider building it into your clinic or home health workflow.

1. Standardized NPWT template

Create an EHR template for NPWT visits that prompts clinicians to document:

• Wound measurements (L/W/D, area)
• Number of wounds and total area
• Device brand, pressure, and mode
• Dressing details and frequency
• Patient instructions

This reduces the chance that crucial elements will be missed when notes are written in a hurry.

2. Coding “cheat card” for front-line staff

A simple one-page reference for staff and providers could include:

• When to use 97607 vs 97608
• Which devices at your organization count as “disposable NPWT”
• Sample phrasing for documentation
• Revenue code mappings for different settings

3. Regular chart audits

Have your coding or compliance team periodically review a sample of NPWT charts to check:

• Code selection (97607 vs 97608 vs other NPWT codes)
• Completeness of documentation
• Alignment with payer policy

Catching issues early can save a lot of downstream headaches.

Essential Takeaways for CPT 97607

To wrap everything together smoothly, here are the main points to remember:

• CPT 97607 is for disposable, non-durable NPWT systems when the total wound surface area is ≤ 50 cm², billed per session.
• The code includes the device, supplies, wound assessment, topical applications, and patient education; no separate supply HCPCS are usually billed.
• Choose between 97607 and 97608 based on the sum of all wound areas treated during that session.
• Proper billing requires the right revenue code and awareness of site-of-service rules, especially in home health.
• Strong documentation should clearly show:

• Wound locations and measurements
• Clinical rationale for NPWT
• Device and dressing details
• Patient/caregiver education

Missteps like using the wrong NPWT code set, double billing supplies, or leaving out surface area details are common causes of denials, but they’re very preventable.
