CPT 49323: Laparoscopic Drainage of Abdominal Lymphocele
CPT code 49323 covers laparoscopic surgical drainage of a lymphocele, a postoperative or post-traumatic collection of lymphatic fluid in the abdomen. The code captures minimally invasive management that opens tissues to allow internal drainage into the peritoneal cavity, with goals of pain relief and infection risk reduction. Nationally, this procedure matters as a targeted surgical option following abdominal trauma or extensive abdominal operations, and it factors into surgical quality, resource utilization, and post‑operative care pathways.
Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication presents a clinical and billing overview, typical sites of service, and common payer coverage themes. Readers will find concise benchmarks for utilization and reimbursement context, notes on coding considerations, and clinical context for when laparoscopic drainage is used versus alternative approaches. Data not available in the input is clearly flagged where applicable.
This summary equips surgical leaders, coding professionals, and payers with the essentials of CPT code 49323, clarifying the procedure it represents, the service setting, and the national payer landscape addressed in the full publication.

Billing Code Overview
CPT code 49323 describes a laparoscopic procedure in which the provider opens tissues to allow a lymphocele (a localized collection of lymphatic fluid) to drain into the peritoneal cavity. The procedure is performed using a laparoscope, a tubular instrument with a light source and camera, to visualize the abdominal cavity and create a controlled internal drainage pathway to relieve pain and reduce the risk of infection.
Service type: Laparoscopic surgical drainage of lymphocele
Typical site of service: Inpatient or outpatient surgical setting using an operating room or ambulatory surgery center, where laparoscopic abdominal procedures are performed.
Clinical & Coding Specifications
Clinical Context
A 58-year-old male presents 6 weeks after radical prostatectomy with progressive lower abdominal fullness, localized discomfort, and intermittent low-grade fevers. Imaging (abdominal ultrasound and CT) demonstrates a 6 cm loculated lymphocele adjacent to the pelvic sidewall causing pain and concern for secondary infection. The patient is scheduled for a laparoscopic drainage with creation of a peritoneal window to allow continuous drainage of the lymphatic collection into the peritoneal cavity.
Preoperative workflow includes history and physical, review of prior operative reports, informed consent for minimally invasive drainage, preoperative antibiotics per facility protocol, and anesthesia evaluation. In the operating room under general anesthesia, the surgeon establishes laparoscopic access, identifies the lymphocele, opens the overlying tissue, enlarges the fenestration to create a permanent communication with the peritoneal cavity, inspects for hemostasis, and closes port sites. Postoperative workflow includes PACU recovery, pain control, vital sign monitoring, and follow-up imaging or clinic visit to confirm resolution of collection and absence of complications.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the procedure required substantially greater work or complexity than usual, documented with rationale. |
23 | Unusual anesthesia | Use if medically necessary anesthesia was required but not ordinarily used for this procedure, documented accordingly. |
26 | Professional component | Use when reporting only the physician’s professional component separate from technical facility resources (rare for operative laparoscopy). |
51 | Multiple procedures | Use when multiple distinct procedures are performed during the same operative session; appended to secondary procedure codes per payer rules. |
52 | Reduced services | Use when the procedure was partially reduced or not completed as described, with documentation of limitation. |
53 | Discontinued procedure | Use when the procedure was started but terminated due to extenuating circumstances, with documentation. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct portions of the procedure. |
66 | Surgical team | Use when a surgical team approach is used and payer accepts team reporting. |
78 | Return to OR for related procedure during global period | Use when patient returns to the operating room for a related procedure during the postoperative global period. |
79 | Unrelated procedure or service by the same physician during global period | Use when an additional procedure unrelated to the global postoperative period is performed. |
80 | Assistant surgeon | Use when an assistant surgeon actively assists and an assistant fee is billable. |
81 | Minimum assistant surgeon | Use for minimal assistance by another surgeon when payer allows. |
62 | Two surgeons (duplicate listed above) | Duplicate entries should be avoided; 62 is the standard code for two primary surgeons. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | Use when an approved non-physician practitioner serves as surgical assistant per payer policy. |
