CPT Code for Removal of Peritoneal Dialysis Catheter

If you are a medical coder, a billing specialist, or a nephrologist, you know that peritoneal dialysis (PD) is a life-saving treatment for patients with end-stage renal disease.

But what happens when that catheter needs to come out? Maybe the patient received a kidney transplant. Perhaps an infection made continued use impossible. Or the patient simply switched to hemodialysis.

Whatever the reason, you are now facing one crucial question: What is the correct CPT code for removal of a peritoneal dialysis catheter?

The answer is not always as simple as looking up a single number. The correct code depends entirely on how the surgeon removes the catheter. Is it a simple pull in an office setting? Or a complex surgical extraction in an operating room?

In this guide, we will walk you through every scenario. You will learn the specific codes, the documentation requirements, and the common mistakes to avoid. Let us get started.

Understanding the Peritoneal Dialysis Catheter

Before we talk about removal codes, we need to understand the device itself. A peritoneal dialysis catheter is usually a soft, flexible tube made of silicone or polyurethane. Surgeons often place it surgically into the lower abdomen.

The catheter allows dialysis solution to flow into the peritoneal cavity. This membrane acts as a natural filter. Over time, the body forms scar tissue around the “cuff” of the catheter. This cuff holds the tube in place and prevents leaks.

This cuff is the main reason why removal is not always straightforward. Sometimes the cuff releases easily. Other times, it is deeply embedded in scar tissue. The surgical effort required to free that cuff dictates the code you will use.

The Primary CPT Code for Removal (Simple)

Let us address the most common scenario first.

If a physician removes a peritoneal dialysis catheter by simply pulling it out through the skin without making a new incision or dissecting through deep scar tissue, you will use a specific code.

The primary code for a simple, percutaneous removal is CPT 49418.

According to the American Medical Association (AMA), CPT 49418 describes the removal of a peritoneal dialysis catheter through the skin without a separate surgical incision. The physician may apply manual traction to pull the catheter out. The cuff may come out with the tube. This is often called a “simple extraction” or “office pull.”

However, there is a critical note you must understand. CPT 49418 is technically bundled. Many payers consider this code part of the global surgical package for the original catheter placement. This means that if the patient is still within the global period of the initial insertion (usually 90 days), you may not get separate reimbursement.

For removal after the global period, or when a different surgeon performs the removal, CPT 49418 is appropriate.

When to Use CPT 49418

• The catheter is removed in an office, clinic, or emergency room.

• The physician uses only gloved hands and gentle traction.

• No scalpel is used to cut the skin.

• The removal takes less than 15 minutes.

• There are no significant adhesions requiring sharp dissection.

The Secondary Code for Complex Surgical Removal

Now, let us discuss the more involved procedure.

Sometimes, the catheter does not come out easily. The cuff may be trapped in dense scar tissue. The catheter may be broken, leaving fragments behind. Or the patient may have developed an infection that requires complete excision of the tunnel tract.

In these cases, the physician must make an incision. They must dissect down to the cuff and free the catheter from the surrounding tissue. This is a surgical procedure.

The code for a complex, open surgical removal is CPT 49422.

CPT 49422 is defined as the removal of a peritoneal dialysis catheter requiring a separate surgical incision. This code includes the dissection of the cuff, the removal of the catheter, and the closure of the deep tissue and skin.

This code is significantly more valuable in terms of relative value units (RVUs) because it requires more skill, time, and operating room resources.

When to Use CPT 49422

• The surgeon makes a skin incision over the cuff site.

• Sharp or blunt dissection is necessary to free the embedded cuff.

• The catheter is broken, and the physician must retrieve fragments.

• The patient has tunnel infection requiring excision of infected tissue.

• The procedure takes place in an operating room or ambulatory surgical center.

Comparative Table: CPT 49418 vs. CPT 49422

To make this decision easier, here is a side-by-side comparison.

What About CPT 49420 and 49421?

You might search online and find codes like CPT 49420 (removal of peritoneal dialysis catheter, open) or CPT 49421 (removal of peritoneal dialysis catheter, laparoscopic).

Important note for 2026: These codes are outdated or have been revised in recent years. Always use the most current CPT manual. As of today, CPT 49418 and 49422 are the standard, accepted codes for catheter removal. Some older references may list 49420, but modern coding practice favors 49422 for open removal. Do not use legacy codes without verifying with your specific payer.

Laparoscopic Removal: Is There a Specific Code?

What if the catheter has migrated into the abdominal cavity? This is a rare but serious complication. The catheter tip may coil or the entire tube may slip inside. You cannot pull it out through the skin.

In this emergency scenario, the surgeon must perform a laparoscopy. They insert a camera into the abdomen, locate the catheter, grasp it, and remove it through a small port site.

There is no specific “laparoscopic removal of PD catheter” code. Instead, you must report the procedure using the code that best describes the work performed.

The most common approach is to use CPT 49321 (Laparoscopy, surgical; with removal of foreign body). The catheter is considered a foreign body in this context. Alternatively, you may use an unlisted laparoscopy code (CPT 49329) with a detailed operative report. However, most coders and payers accept 49321 for this specific situation.

Always attach a cover letter explaining that the laparoscopy was used to retrieve a migrated PD catheter.

Modifiers You Need to Know

Using the correct CPT code is only half the battle. You also need the right modifiers. Modifiers tell the payer that something unique happened.

Modifier 47 (Anesthesia by Surgeon)

If the surgeon personally administers local or regional anesthesia without the help of an anesthesiologist, you may append Modifier 47 to the surgical code. This is rare for PD catheter removal but possible in small office settings.

Modifier 52 (Reduced Services)

What if the physician starts a complex removal (CPT 49422) but finds that the catheter comes out easily after only a small incision? The full service was not performed. In this case, you can append Modifier 52 to indicate reduced services. Include a note in the medical record explaining why.

Modifier 78 (Return to OR)

If the patient had a catheter removal but develops a complication (like a hematoma or infection) and needs to return to the operating room within the global period, you use Modifier 78. This tells the payer that the second procedure is related but unplanned.

Modifier 79 (Unrelated Procedure)

If the patient is in the global period of a different surgery (like a hernia repair), and the PD catheter removal is completely unrelated, use Modifier 79. This prevents the payer from bundling the removal into the prior surgery’s global package.

Real-World Scenarios and Coding Examples

Theory is helpful, but real cases teach the best lessons. Let us look at five common patient scenarios.

Scenario 1: The Routine Office Pull

Patient story: Mrs. Johnson received a kidney transplant six months ago. She no longer needs PD. Her nephrologist asks the general surgeon to remove the catheter. In the clinic, the surgeon applies gentle traction. The catheter slides out with the cuff attached. A bandage is applied.

Correct coding: CPT 49418. No modifier needed. The global period for the original insertion ended long ago.

Scenario 2: The Stuck Cuff

Patient story: Mr. Lee has been on PD for four years. His catheter cuff is heavily embedded. The surgeon tries to pull it in the office, but it will not budge. The patient is taken to the operating room. The surgeon makes a 2 cm incision, dissects the cuff free, removes the catheter, and closes the wound with two sutures.

Correct coding: CPT 49422. Append Modifier 47 if the surgeon also administered the local anesthesia.

Scenario 3: Infected Tunnel Tract

Patient story: Ms. Garcia has a chronic tunnel infection. Antibiotics failed. The surgeon must remove the catheter and excise the entire infected tract. The procedure involves cutting out a small ellipse of skin around the exit site and removing all infected tissue.

Correct coding: CPT 49422. Additionally, you may report CPT 11400 (excision of benign lesion) for the skin ellipse if the documentation supports it. However, most payers consider the excision part of the catheter removal. Check local coverage determinations (LCDs).

Scenario 4: The Migrated Catheter

Patient story: Mr. Chen complains of abdominal pain. An X-ray shows his PD catheter has completely migrated into the peritoneal cavity. The surgeon performs a diagnostic laparoscopy, finds the catheter near the liver, grasps it with forceps, and removes it through a 5 mm port site.

Correct coding: CPT 49321 (Laparoscopy, removal of foreign body). Do not use 49418 or 49422 because the catheter is no longer accessible through the skin.

Scenario 5: Removal During Another Surgery

Patient story: Mrs. Davis is scheduled for an elective cholecystectomy (gallbladder removal). She also has an unused PD catheter from a failed PD trial two years ago. The surgeon removes the catheter laparoscopically during the same operation.

Correct coding: For the gallbladder, use CPT 47562. For the catheter removal, use CPT 49321 with Modifier 51 (multiple procedures) or Modifier XS (separate structure). The payer will reimburse the catheter removal at a reduced rate because it is a secondary procedure.

Documentation Requirements for Successful Reimbursement

Payers deny claims for missing documentation more often than for incorrect coding. Do not let this happen to you. Ensure the operative note or procedure note includes the following five elements.

1. Indication for Removal

Why is the catheter coming out? Transplant? Infection? Patient choice? Failure of PD? Write this clearly. For infection, specify the organism and antibiotic failure.

2. Attempted Simple Removal

If you bill for a complex removal (49422), the note must state that simple traction was attempted first and failed. Example: “Attempted manual traction in the clinic on 4/1/2026 was unsuccessful due to a densely adherent cuff.”

3. Description of Surgical Technique

Be specific. Do not write “catheter removed.” Write: “A 1.5 cm transverse incision was made over the palpable cuff. Sharp dissection with Metzenbaum scissors was used to free the cuff from the surrounding fibrotic tissue. The catheter was delivered intact. The wound was irrigated and closed in two layers.”

4. Catheter Integrity

State whether the catheter came out whole. If it broke, describe how you retrieved the fragments. Missing fragments must be documented and imaged.

5. Closure Method

Did you use sutures? Steri-Strips? A pressure dressing? Deep sutures indicate a complex procedure. A simple bandage indicates a simple procedure.

Common Billing Mistakes to Avoid

Even experienced coders make errors. Here are the most frequent pitfalls for PD catheter removal coding.

Mistake #1: Using 49418 for a Surgical Dissection

This is the most common error. A physician makes an incision but bills the simple code to avoid a denial. This is incorrect and constitutes undercoding (which is still fraud). If the scalpel touches the skin, you are likely in 49422 territory.

Mistake #2: Billing for Removal During the Global Period

Most payers consider catheter removal (even complex) as part of the original placement’s global package if performed within 90 days. If the patient had a transplant at day 85 and the same surgeon removes the catheter, do not bill separately. Only bill if a different surgeon or a different specialty performs the removal.

Mistake #3: Forgetting the -59 Modifier for Same-Day Procedures

If a patient has a hernia repair and a PD catheter removal on the same day by the same surgeon, you must append Modifier 59 (distinct procedural service) or XS to the catheter code. Otherwise, the payer will bundle the removal into the hernia repair.

Mistake #4: Using Unlisted Codes Without Trying Specific Codes First

Unlisted codes (such as 49429 for unlisted peritoneal procedure) should be your last resort. They require a cover letter and often result in manual review and delayed payment. Always use 49418, 49422, or 49321 first.

Medicare and Commercial Payer Policies

Reimbursement for PD catheter removal varies by payer. However, there are general trends you should know.

Medicare National Coverage Determinations (NCDs)

Medicare does not have a specific NCD for PD catheter removal. However, local MACs (Medicare Administrative Contractors) may have LCDs. For example, some MACs require prior authorization for CPT 49422 when performed in an outpatient hospital setting. Check your local MAC before scheduling the procedure.

Commercial Payers

UnitedHealthcare, Aetna, Cigna, and Blue Cross generally cover PD catheter removal as medically necessary. The most common covered indications are:

• Successful kidney transplantation.

• Permanent transfer to hemodialysis.

• Refractory peritonitis or tunnel infection.

• Catheter malfunction (leak, obstruction, migration).

• Patient preference (after appropriate counseling).

Some payers require documentation of failed conservative management for infections. For example, they may want to see at least 7 to 14 days of failed antibiotic therapy before approving surgical removal.

The Role of Modifier 22 (Increased Procedural Services)

Sometimes a catheter removal is even more complex than usual. The patient may have massive intra-abdominal adhesions from previous surgeries. The catheter may be encased in a thick inflammatory mass.

In these rare cases, you can append Modifier 22 to CPT 49422. This modifier tells the payer: “This was significantly more work than typical.”

To successfully use Modifier 22, the operative report must include:

• A detailed description of the unexpected difficulty.

• The additional time required (e.g., “The dissection took 45 minutes compared to the usual 15 minutes”).

• The increased mental and physical effort.

• Any intraoperative complications.

Do not overuse Modifier 22. Payers scrutinize it heavily. Use it perhaps once or twice a year for truly exceptional cases.

What About Removal of a Broken Catheter?

Catheters can break. The silicone may weaken over time. Or a patient may accidentally cut the external portion.

If the external portion is missing, the internal portion may retract under the skin. The surgeon must make an incision to retrieve the broken fragment.

Coding guidance: If the surgeon makes an incision to retrieve a broken fragment, use CPT 49422. The work is identical to removing an intact catheter with an embedded cuff. The only difference is that the catheter is in pieces.

Do not use a foreign body removal code (CPT 10120 for superficial foreign body removal) because the catheter is not superficial. It lies in the deep subcutaneous tissue or peritoneal cavity.

How to Report Catheter Removal with Simultaneous Replacement

What if the patient needs a new PD catheter at the same time as the old one is removed? For example, the old catheter is infected, and the surgeon wants to place a new one in a different location.

In this case, you report two codes:

• CPT 49422 for the removal of the old catheter.

• CPT 49421 (or the appropriate placement code) for the new catheter insertion.

Append Modifier 59 or XU to the removal code to indicate it is a distinct procedure. The payer will reimburse both, although often at a reduced rate for the second procedure.

Important safety note: Most guidelines recommend waiting at least two weeks between removing an infected catheter and placing a new one. Same-day removal and replacement is controversial and may not be covered. Check your payer’s policy on “same-site” versus “different-site” placement.

Anesthesia Coding for PD Catheter Removal

The surgeon removes the catheter. But who handles the anesthesia?

For CPT 49418 (Simple Removal)

Usually, no anesthesia code is billed. The surgeon may apply topical lidocaine. This is included in the procedure. Do not bill a separate anesthesia code.

For CPT 49422 (Complex Removal)

The anesthesia is often separate. An anesthesiologist or certified registered nurse anesthetist (CRNA) will bill their own codes. The most common anesthesia codes are:

• CPT 00750 (Anesthesia for intraperitoneal procedures in the lower abdomen, including peritoneal dialysis catheter insertion or removal).

• CPT 00811 (Anesthesia for lower abdominal surgery, including laparoscopy).

The anesthesia code depends on the patient’s physical status (ASA score) and the time involved. The surgeon does not bill these codes. The anesthesia provider does.

If the surgeon personally administers monitored anesthesia care (MAC) without an anesthesia provider, the surgeon can bill the anesthesia using Modifier 47 appended to the surgical code. This is rare.

Geographic and Site of Service Variations

Where the procedure takes place changes the reimbursement amount.

These are estimates. Actual reimbursement varies by region, payer contract, and Medicare fee schedules.

Important Notes for Readers

Note 1: CPT codes are updated annually. The information in this article is accurate for 2026. Always verify codes with the current AMA CPT manual and your local payer policies before submitting claims.

Note 2: Do not bill for catheter removal if the patient is still within the 90-day global period of the original insertion, unless a different surgeon performs the removal. This is a frequent cause of audits and recoupments.

Note 3: For infected catheters, payers may require a culture and sensitivity report showing failed medical therapy. Attach this documentation to your claim proactively to avoid denials.

Note 4: If the catheter is removed during a kidney transplant surgery, do not bill separately. The removal is considered part of the transplant procedure (CPT 50360 or 50365).

Frequently Asked Questions (FAQ)

1. Can a nurse remove a peritoneal dialysis catheter?

No. In almost all jurisdictions, a physician (MD or DO) must remove a PD catheter. Some advanced practice providers (NPs or PAs) may remove simple catheters under supervision, but the billing must occur under the supervising physician’s NPI. Check state scope-of-practice laws.

2. Is the removal of a PD catheter painful?

Simple removal is usually mildly uncomfortable but not severely painful. Surgeons use local anesthesia. Complex removal requires deeper anesthesia. Patients report a pulling sensation followed by relief.

3. How long does recovery take after removal?

For simple removal (CPT 49418), patients resume normal activities immediately. For complex removal (CPT 49422), patients need about one week of limited activity. No heavy lifting for two weeks. The small incision heals quickly.

4. Does insurance always cover PD catheter removal?

Yes, when medically necessary. Covered reasons include transplant, infection, mechanical failure, and transfer to hemodialysis. Elective removal for patient convenience is also usually covered after appropriate documentation.

5. What happens if the cuff is left behind?

Sometimes the cuff separates from the tube during simple removal. If the cuff is left in the tissue, it is usually harmless. The body absorbs or encapsulates it. No further surgery is needed unless the cuff becomes infected. If infection occurs, a second procedure (CPT 49422) removes the retained cuff.

6. Can I bill an office visit (E/M code) on the same day as the removal?

Yes, if a separately identifiable evaluation and management service was performed before the decision to remove the catheter. Append Modifier 25 to the E/M code (e.g., 99213-25). Document the medical decision-making for removal separately from the procedure itself.

7. What is the difference between “removal” and “revision”?

Revision (CPT 49420 for open revision) involves adjusting or repairing the existing catheter without removing it entirely. Removal (49418 or 49422) means taking it out completely. Do not confuse the two. Revision is rare because catheters are usually replaced rather than repaired.

Conclusion

Selecting the right CPT code for removal of a peritoneal dialysis catheter comes down to one question: Did the surgeon make an incision? For a simple, traction-only removal, use CPT 49418. For any removal requiring a scalpel, dissection, or sutures, use CPT 49422. Always document the failed simple attempt before billing a complex removal, and never forget to check the global period of the original surgery.
