CPT Code for Wound Packing and Dressing: A Complete Guide for 2026

Let’s be honest. Wound care is messy, detailed work. But billing for it? That can feel even trickier.

You just finished a thorough wound packing and dressing change. The patient is stable. You documented everything. Then comes the dreaded question: what is the correct CPT code for wound packing and dressing?

You are not alone if you feel stuck. Many medical coders, nurses, and even physicians mix up these codes.

The short answer is that there is no single “wound packing and dressing” code. Instead, you choose between active wound management codes (like 97597) and simple surface codes (like 97602). The right choice depends on the wound type, depth, and what you actually did.

In this guide, we will walk through every relevant code step by step. We will use plain English, realistic examples, and helpful tables. By the end, you will feel confident picking the right code and avoiding costly denials.

Why Getting the Right CPT Code for Wound Packing and Dressing Matters

Before we dive into numbers, let’s talk about the “why.” This is not just paperwork.

Using the wrong code leads to three real problems.

First, you lose money. If you undercode, you leave revenue on the table. If you overcode, you face clawbacks.

Second, you trigger audits. Payers watch wound care closely. It is a high-risk area for fraud.

Third, you confuse patient records. Accurate coding supports good clinical communication.

So taking ten extra minutes to learn these codes saves you hours of headache later.

The Core Difference: Active vs. Simple Wound Care

Most confusion comes from one central idea. You need to ask yourself: did I perform active wound management or simple wound care?

Let me explain.

Active wound management means you remove dead tissue, debris, or foreign material. You clean the wound thoroughly. You pack it deeply. This is for chronic, surgical, or traumatic wounds that are healing slowly.

Simple wound care means the wound is clean. You just remove the old dressing, apply a new dry or wet dressing, and send the patient home. No scrubbing. No scraping. No deep packing.

The CPT manual separates these two categories clearly.

Here is the most important rule of thumb:

• If you touched the wound bed with a tool (scalpel, curette, gauze with friction) → active code.

• If you only touched the dressing → simple code.

The Primary CPT Codes for Wound Packing and Dressing

Let us look at the specific codes you will use most often. I will list them, explain them, and then show you a comparison table.

97597 – Active Wound Debridement (First 20 sq cm)

This is the workhorse code for packing and dressing complex wounds.

What it includes: Removal of devitalized tissue, cleaning, and preparation for dressing. The packing itself is not separately billed when done during the same session as debridement. It is considered part of the service.

When to use: A patient has a diabetic foot ulcer. You use gauze or a curette to remove slough. Then you irrigate, pack the wound with saline-soaked gauze, and apply a dry dressing.

Key detail: This code covers the first 20 square centimeters of wound surface. You measure the wound at its longest and widest points.

97598 – Active Wound Debridement (Each additional 20 sq cm)

Use this add-on code with 97597.

What it includes: Same work as above, but for every extra 20 square centimeters beyond the first 20.

Example: A wound measures 45 sq cm. You bill 97597 for the first 20 sq cm, and 97598 twice for the remaining 25 sq cm.

97602 – Simple Wound Dressing (Non-debridement)

This is the code for clean, straightforward dressing changes.

What it includes: Removal of old dressing, assessment of the wound, application of a new dressing (wet or dry), and patient instructions.

No packing? Actually, you can use 97602 for simple packing of a clean wound without debridement. For example, a post-operative wound that is granulating well. You just place fresh packing strips into the tunnel without scraping.

Important note: Many payers limit 97602 to once per day per wound. Also, some commercial insurers do not reimburse it at all for routine care at home.

97605 – Negative Pressure Wound Therapy (NPWT) First 50 sq cm

This is for vacuum-assisted closure (VAC) dressings.

What it includes: Placement of foam or gauze into the wound, sealing with a transparent film, attaching tubing, and connecting to the pump.

Packing connection: The foam acts as the “packing” material. This code covers the entire dressing setup.

97606 – NPWT Each additional 50 sq cm

Add-on code for larger wounds requiring negative pressure therapy.

Note: Code S9083 is a HCPCS code, not a CPT code. Some Medicare Advantage plans use it for daily wound care visits. Check your local payer.

Common Real-Life Scenarios: Which Code Do You Pick?

Let’s move from theory to practice. Here are five typical patient cases.

Scenario 1: The Post-Op Surgical Wound

A patient returns to your clinic five days after abdominal surgery. The wound is clean, pink, and healing. You remove the dry gauze, wash gently with saline, apply new dry gauze, and tape it.

No packing needed. No debridement.

Correct code: 97602 (simple dressing change)

Scenario 2: The Diabetic Foot Ulcer with Slough

The patient has a 10 sq cm ulcer on the heel. Yellow slough covers 40% of the wound bed. You use a sterile gauze pad to rub off the slough. You irrigate with saline. Then you pack the wound loosely with iodoform gauze. Finally, you apply an outer dry dressing.

You debrided (mechanical friction). You packed.

Correct code: 97597 (active debridement first 20 sq cm). Do not bill separate packing.

Scenario 3: Home Health Follow-Up for a Clean Tunneled Wound

A home health nurse visits a patient with a healed surgical wound that has a small, clean tunnel (2 cm deep). The wound bed is red and granulating. No debris. The nurse simply places a packing strip into the tunnel and covers it.

No debridement. Simple packing of a clean wound.

Correct code: 97602

Scenario 4: The Pressure Injury with Eschar

A nursing home resident has a sacral pressure injury measuring 30 sq cm. Thick black eschar covers the surface. You cannot remove it with gentle scrubbing. You apply an enzymatic ointment and a dry dressing. No sharp debridement today.

You did not remove tissue. You applied a dressing.

Correct code: 97602 (even though the wound is complex). Why? Because you did not actively debride.

Scenario 5: VAC Dressing Change

A patient with a traumatic leg wound has a VAC device. You remove the old foam, measure the wound, cut new foam, place it deep into the wound, seal the film, and reconnect the tubing.

Packing is the core of this service.

Correct code: 97605 (first 50 sq cm). Add 97606 if wound exceeds 50 sq cm.

How to Document Wound Packing and Dressing for Coding Success

You can pick the perfect code, but if your documentation is weak, you will still get denied.

Here is a simple checklist for every wound care note.

Required elements:

1. Wound location (e.g., left lateral malleolus)

2. Wound dimensions (length x width x depth in cm)

3. Wound bed description (granulation, slough, eschar, necrotic tissue)

4. Exact procedure (irrigation, debridement type, packing material)

5. Packing details (depth packed, type of gauze, wet vs dry)

6. Outer dressing (type, securement method)

7. Time (if time-based coding applies – rare for these codes)

8. Patient tolerance (no complications, tolerated well)

Example of strong documentation:

*“Right heel diabetic ulcer, 3.5 cm x 2 cm x 0.5 cm. Wound bed has 30% yellow slough. Used sterile dry gauze to mechanically debride slough. Irrigated with 100 mL normal saline. Packed loosely with saline-moistened ¼-inch gauze strip to depth of 0.5 cm. Covered with dry sterile gauze and tape. Patient tolerated well. No bleeding.”*

That note clearly supports 97597.

What About Packing Alone Without a Dressing Change?

Sometimes a patient comes in just for packing removal and replacement. The outer dressing is still clean.

Can you bill for that?

Yes, but you need to be careful.

If you remove the packing, assess the wound, and replace the packing without changing the outer dressing, you still performed a procedure. Use 97602 if no debridement occurs.

However, many payers consider this part of an evaluation and management (E/M) service. If you also examine the patient for infection or healing, bill an office visit (99212-99215) plus 97602 only if the work is separate and significant.

A safe rule: document why the packing change required a separate visit. For example: “Packing was retained for 48 hours. Patient unable to remove at home. Required sterile removal and reassessment.”

Medicare and Payer Policies for Wound Packing Codes

Medicare is the biggest payer for wound care. Their rules often set the standard.

Medicare’s stance on 97602: They cover it, but only for active wound care. They do not pay for routine dressing changes that a patient or caregiver can do at home.

Medicare’s stance on 97597: They cover it for chronic wounds (diabetic ulcers, pressure injuries, venous stasis ulcers). They do not cover debridement of acute surgical wounds that are healing normally.

Private insurers: Vary widely. Some require prior authorization for 97597. Others bundle packing into a global surgical package.

Action step: Call your top five payers. Ask them: “Do you reimburse 97602 for simple packing of a clean granulating wound?” Get a yes or no in writing.

The Most Common Coding Mistakes (And How to Avoid Them)

I have reviewed hundreds of wound care charts. These are the errors I see most often.

Mistake #1: Billing 97597 for a Simple Gauze Change

Why it happens: The nurse remembers packing the wound. They think packing = complex.

Fix: Ask yourself: “Did I remove any tissue?” If no, use 97602.

Mistake #2: Billing 97602 When You Actually Debrided

Why it happens: Coders are afraid of audit risk for higher codes.

Fix: Undercoding is still incorrect coding. If you scrubbed off slough, bill 97597.

Mistake #3: Forgetting the Add-On Code 97598

Why it happens: The wound is larger than 20 sq cm, but the coder only bills 97597 once.

Fix: Measure every time. Calculate total surface area. Bill 97598 for each additional 20 sq cm.

Mistake #4: Billing Packing Separately

Why it happens: Old training suggested a separate packing code. There is none.

Fix: Packing is bundled into the primary procedure code (97597, 97602, or 97605).

Mistake #5: Using Facility Codes in a Clinic

Why it happens: Confusion between hospital and outpatient coding.

Fix: In a physician’s office, use 97597 and 97602. In a hospital outpatient department, you may use C-codes (e.g., C9757). Always check your facility’s chargemaster.

A Note on Supplies and Dressing Materials

You cannot bill separately for gauze, tape, saline, or packing strips. These are included in the procedure code’s practice expense.

The only exception is if you use a costly biologic dressing or skin substitute. Those have separate HCPCS codes (Q-codes or A-codes).

Examples:

• A6021 – Collagen dressing, small

• A6022 – Collagen dressing, large

• Q4100 – Skin substitute, per square cm

So if you pack a wound with a collagen matrix, you bill 97597 or 97602 for the service plus the appropriate HCPCS code for the material.

Document the size of the dressing applied. Payers want to see that the amount matches the wound size.

Realistic Reimbursement Expectations

Let’s talk money. These numbers vary by region and payer. But here are rough Medicare physician fee schedule amounts (2026, facility setting):

Non-facility (office) rates are slightly higher because they include supplies.

Private insurers may pay 120% to 200% of Medicare rates.

Do not assume you will get paid for 97602 on every visit. Many Medicare Administrative Contractors (MACs) limit it to three times per week per wound.

When to Use Evaluation and Management (E/M) Codes Instead

Sometimes a dressing change is not the main service.

Imagine a patient comes in for a wound check. You spend 20 minutes assessing healing, adjusting antibiotics, and teaching the family. You also change the dressing.

In this case, bill the E/M code (99213 or 99214) based on medical decision making. Do not bill 97602 separately because the dressing change is part of the E/M service.

But if the patient comes specifically for a dressing change and you do not perform any separately identifiable assessment, bill only 97602.

The rule: same date, same patient, same provider. If the dressing change is minor and bundled into the visit, pick one code. If it is extensive and distinct, you may bill both with modifier -25 on the E/M code.

Example of proper modifier -25 use:

*99214 (level 4 office visit for infected wound evaluation) and 97597 (debridement and packing) with modifier -25 appended to 99214. Documentation shows the E/M service was separate and significant.*

How to Handle Multiple Wounds on the Same Patient

A patient has three separate pressure injuries. You pack and dress all three.

Can you bill for each wound?

For 97597 and 97598: Yes, but only if the wounds are on different anatomical sites (e.g., sacrum and left heel). Add modifier -59 (distinct procedural service) to the second and third wounds.

For 97602: Generally, no. Most payers consider this a global service per session. Bill one unit of 97602 regardless of the number of simple dressings changed.

Example: Two wounds, both require debridement and packing. Left heel (15 sq cm) and right heel (12 sq cm). Bill 97597 twice with modifier -59 on the second. Do not bill 97598 because each wound is under 20 sq cm.

The Future of Wound Packing Codes

CPT codes change every year. For 2025 and 2026, no major changes have been announced for 97597, 97598, or 97602.

However, the AMA is watching telehealth wound care closely. Some remote therapeutic monitoring (RTM) codes now apply to wound care. For example, 98975 for remote monitoring setup and 98976 for remote monitoring of wound characteristics.

Will packing codes move to telehealth? Unlikely. Packing requires physical contact. But dressing assessment and patient education may shift to virtual visits.

Stay current. Check the CPT manual each October.

Frequently Asked Questions (FAQ)

1. Can I bill a CPT code for wound packing and dressing if the patient does it themselves at home?

No. CPT codes are for professional services performed by a licensed clinician. Patient self-care is not billable.

2. What is the CPT code for removing old packing only?

There is no separate code for removal alone. Removal is included in the next dressing change service (97602 or 97597).

3. Is there a CPT code for wound packing without debridement?

Yes. Use 97602 for simple packing without debridement.

4. Does Medicare cover daily dressing changes for chronic wounds?

It depends. If the patient cannot perform the change due to disability or wound complexity, Medicare may cover it. Routine changes that a caregiver can do are not covered.

5. How do I bill packing for a wound that tunnels?

Measure the tunnel depth. Document the length, width, and depth. Use 97602 if the tunnel is clean. Use 97597 if you debride the tunnel lining.

6. What modifier do I use for bilateral wound packing?

Modifier -50 (bilateral procedure). But this is rare for wound packing. Most coders use modifier -59 for separate anatomical sites.

7. Can a medical assistant bill for a dressing change?

No. The service must be performed by a qualified healthcare professional (MD, DO, NP, PA, RN, or LPN within their scope). The billing provider is the clinician who supervised or performed the work.

8. What is the difference between 97602 and G0457?

G0457 is a Medicare code for low-risk wound care performed by a nurse under a care plan. It is not commonly used anymore. Stick with 97602 for non-Medicare and many Medicare scenarios.

Final Thoughts and Practical Advice

Let me leave you with three simple rules.

First, always document the wound bed. If you see slough or eschar, lean toward 97597. If you see clean granulation tissue, lean toward 97602.

Second, do not invent codes. There is no “packing only” CPT code separate from dressing or debridement. Packing is bundled.

Third, when in doubt, call your payer’s provider line. Ask a specific question like, “For a clean 5 cm tunneled wound with no debris, do you reimburse 97602 for packing and dressing?” Record the answer.

Wound packing and dressing is essential care. Your coding should reflect that value without overstepping. Use this guide as your reference. Bookmark it. Share it with your team.

You now have the tools to code with confidence.

Conclusion

Choosing the right CPT code for wound packing and dressing depends on whether you performed active debridement (97597) or simple dressing change (97602). Packing is always bundled into the primary procedure code, never billed separately. Always document wound characteristics thoroughly and verify payer policies to avoid denials.
