🔬 CPT 49324 — Laparoscopy, Surgical; With Insertion of Tunneled Intraperitoneal Catheter
Quick Reference
wRVU: 6.16¹ | Global Period: 090 | Assistant Payable: Rarely necessary | Bilateral Indicator: 0 Rule: CPT 49324 describes the laparoscopic (not open or percutaneous) approach to tunneled intraperitoneal catheter placement; an open approach is reported with a different code, and a fully percutaneous, image-guided placement is reported with yet another distinct code³. When a subcutaneous extension with a remote chest exit site is also created in the same session, add-on code 49435 is reported in conjunction with **49324**⁴.
📋 Clinical Description
CPT 49324 describes laparoscopic placement of a tunneled catheter into the peritoneal cavity, most commonly used to establish access for peritoneal dialysis in patients with end stage renal disease, though it is also used for intraperitoneal chemotherapy instillation or management of recurrent malignant or refractory ascites². The laparoscopic approach allows direct visualization of catheter tip placement and omental fixation, which can improve catheter function and reduce migration compared to blind percutaneous techniques.
This code is distinguished from 49421 (open insertion of tunneled intraperitoneal catheter for dialysis), which uses a direct open surgical approach rather than laparoscopic visualization, and from percutaneous, image-guided catheter placement codes, which do not involve laparoscopic access at all. When omental tacking (omentopexy) is performed in the same session to help prevent catheter migration or obstruction, this is reported separately using **add-on code 49326**⁴.
Clinical contexts:
- End stage renal disease requiring peritoneal dialysis access as an alternative to hemodialysis.
- Recurrent malignant ascites requiring intraperitoneal catheter placement for palliative drainage.
- Planned intraperitoneal chemotherapy administration requiring durable peritoneal access.
- Revision or initial placement preference for laparoscopic visualization to optimize catheter tip positioning and reduce migration risk.
- Combined procedures where omental tacking or a subcutaneous extension with remote exit site is planned at the same operative session.
🔬 Anatomical & Procedural Considerations
| Variant | Mechanism | Key Notes |
|---|---|---|
| Standard Laparoscopic Placement | The surgeon uses laparoscopic visualization to guide the tunneled catheter into the pelvis, confirming appropriate tip position under direct view before tunneling the catheter through the abdominal wall. | Direct visualization allows real-time confirmation of catheter positioning, reducing the risk of malposition compared to blind techniques. |
| With Omental Tacking (Add-On) | When omental redundancy poses a risk of catheter obstruction, the surgeon may perform omentopexy to secure the omentum away from the catheter tip. | Reported using add-on code 49326 in conjunction with 49324, never as a standalone code⁴. |
| With Subcutaneous Extension (Add-On) | A subcutaneous tunnel extension to a remote chest exit site may be created in the same session, often for cosmetic or infection-prevention reasons. | Reported using add-on code 49435 in conjunction with 49324, never as a standalone code⁴. |
Clinical Pearl
✅ Procedure Includes
- Laparoscopic access and insufflation of the peritoneal cavity.
- Visualization and positioning of the catheter tip within the pelvis.
- Tunneling of the catheter through the abdominal wall subcutaneous tissue.
- Securing the catheter cuff(s) in the appropriate subcutaneous position.
- Closure of laparoscopic port sites.
❌ Excludes / Do Not Report Together
| Code | Description | Relationship |
|---|---|---|
| 49421 | Insertion of tunneled intraperitoneal catheter for dialysis, open | Represents an open, not laparoscopic, approach to the same general procedure; mutually exclusive based on surgical technique used. |
| 49325 | Laparoscopy, surgical; with revision of previously placed intraperitoneal cannula or catheter, with removal of intraluminal obstructive material if performed | Represents revision of an existing catheter rather than initial insertion; not reported together for the same catheter in the same session. |
| 49322 | Laparoscopy, surgical; with aspiration of cavity or cyst (eg, ovarian cyst) (single or multiple) | Represents a distinct fluid aspiration procedure rather than catheter insertion; not interchangeable with 49324. |
Bundling Alert
The 090-day global period bundles routine postoperative visits, catheter function checks, and wound checks tied to expected recovery within 90 days. An unplanned return to the OR for catheter malfunction or migration requires modifier -78, while a planned staged revision requires modifier -58. Audit risk increases when add-on codes 49326 or 49435 are billed without the required primary procedure code 49324 or 49325 also present on the same claim⁴.

🩺 Common ICD‑10‑CM Pairings
Primary Diagnosis Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| N18.6 | End stage renal disease | Yes | The most common primary diagnosis supporting tunneled intraperitoneal catheter placement for peritoneal dialysis. |
| R18.8 | Other ascites | No | Supports catheter placement when the indication is management of recurrent or malignant ascites rather than dialysis access. |
Secondary Group
| ICD‑10 | Description | HCC? | Notes |
|---|---|---|---|
| Z99.2 | Dependence on renal dialysis | No | Reflects the patient’s ongoing dialysis dependence status supporting the need for peritoneal access. |
Coding Specificity Reminder
Always document the specific indication for catheter placement (dialysis access, chemotherapy administration, or ascites management), since this directly affects primary diagnosis selection. Confirm end stage renal disease status is documented as N18.6 when applicable, since this is an HCC-relevant code with significant risk adjustment impact.
🏥 MS‑DRG Considerations
Inpatient 49324 typically groups within a renal/dialysis-access-related DRG when the primary indication is peritoneal dialysis access, though DRG assignment varies depending on whether the underlying indication is renal failure, malignant ascites, or planned chemotherapy administration. Accurate capture of the underlying primary diagnosis prompting catheter placement is essential for correct DRG assignment.
🔧 ICD‑10‑PCS Equivalents
| PCS Code | Full Description | Modality |
|---|---|---|
| 0W9G30Z | Drainage of peritoneal cavity, percutaneous approach, drainage device | Alternate percutaneous classification when a drainage device remains in place |
| 0W9G3ZZ | Drainage of peritoneal cavity, percutaneous approach | Reflects the peritoneal access component without device specification |
| 0WHG30Z | Insertion of infusion device into peritoneal cavity, percutaneous endoscopic approach | Most closely matches the laparoscopic tunneled catheter insertion described by 49324 |
PCS Character Analysis
| Position | Character | Value | Definition |
|---|---|---|---|
| 1 | Section | 0 | Medical and Surgical section. |
| 2 | Body System | W | Anatomical regions, general, encompassing the peritoneal cavity. |
| 3 | Root Operation | H | Insertion — putting in a nonbiological device that monitors, assists, performs, or prevents a physiological function, matching the catheter placement. |
| 4 | Body Part | G | Peritoneal cavity, the specific anatomic region accessed. |
| 5 | Approach | 4 | Percutaneous endoscopic approach, matching the laparoscopic technique. |
| 6 | Device | 3 | Infusion device, reflecting the tunneled catheter itself. |
| 7 | Qualifier | 0 | No qualifier needed for this component. |
Root Operation Comparison
Insertion (H) is used because a device (the tunneled catheter) is being put in without taking out or altering any body part, distinguishing it from Drainage (9), which would apply if fluid alone were being removed without leaving a device in place. Coders should select the percutaneous endoscopic approach specifically to match the laparoscopic technique used in 49324, since a fully open approach would correspond to a different CPT code (49421) and a different PCS approach value.
📝 Coding Examples
Example 1
Clinical Scenario: A 58-year-old male with end stage renal disease elects peritoneal dialysis over hemodialysis. He undergoes laparoscopic placement of a tunneled intraperitoneal dialysis catheter, with direct visualization confirming appropriate pelvic tip positioning.
| Field | Code | Rationale |
|---|---|---|
| CPT | 49324 | Captures the laparoscopic insertion of the tunneled intraperitoneal catheter for dialysis access. |
| PDx | N18.6 | Documents end stage renal disease as the underlying indication for peritoneal dialysis access. |
Note
Confirm the operative note documents laparoscopic, not open or purely percutaneous, technique, since this determines correct code selection among the available catheter placement codes.
Example 2
Clinical Scenario: A 65-year-old female with recurrent malignant ascites from ovarian cancer undergoes laparoscopic placement of a tunneled intraperitoneal catheter for palliative drainage, with concurrent omental tacking to prevent catheter obstruction from omental redundancy.
| Field | Code | Rationale |
|---|---|---|
| CPT | 49324, 49326 | Reports the primary laparoscopic catheter insertion along with the add-on omentopexy performed in the same session⁴. |
| PDx | R18.8 | Documents the ascites as the indication for catheter placement in this non-dialysis context. |
Note
⚠️ Common Coding Pitfalls
- Reporting 49324 when the catheter was actually placed via an open surgical approach, which requires 49421 instead.
- Billing add-on codes 49326 or 49435 without the required primary procedure code (49324 or 49325) also present on the same claim⁴.
- Confusing initial catheter insertion (49324) with catheter revision (49325), which addresses an already-existing catheter rather than a new placement.
- Failing to append modifier -58 for a planned staged catheter revision performed within the global period.
- Defaulting to an unspecified renal failure or ascites diagnosis code when the documentation supports a more specific underlying etiology.
- Overlooking documentation of dialysis dependence status (Z99.2) as a secondary diagnosis when applicable, understating the full clinical picture.
