Summary & Overview
CPT 49329: Laparoscopic Procedure, Abdomen/Peritoneum/Omentum
CPT code 49329 denotes an unlisted laparoscopic procedure of the abdomen, peritoneum, and omentum and is used when no specific laparoscopic CPT code applies. Nationally, this code matters because it captures a diverse set of minimally invasive abdominal procedures that are not otherwise categorized, affecting billing specificity, prior authorization, and claims adjudication for surgical providers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of how 49329 is used in clinical documentation and billing, common payment and coding considerations, and the typical sites of service where the code is billed. The publication summarizes benchmark practices, payer policy themes, and clinical context for when an unlisted laparoscopic abdominal code is chosen.
This summary prepares clinicians, coding professionals, and revenue cycle staff to understand the role of 49329 in cases without a specific laparoscopic code, what to expect from major payers, and which operational topics to address in billing workflows. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 49329 is an unlisted laparoscopic procedure code used to report laparoscopic operations involving the abdomen, peritoneum, and omentum when no specific CPT code describes the procedure performed. This code captures miscellaneous or uncommon laparoscopic interventions that fall outside defined procedure codes.
-
Service type: Minimally invasive laparoscopic abdominal/peritoneal surgery
-
Typical site of service: Hospital outpatient departments, ambulatory surgery centers, and inpatient hospital operating rooms

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting with non-specific acute or chronic intra-abdominal pathology for which a standard laparoscopic CPT code does not exist or when an unusual laparoscopic procedure is performed in the abdomen, peritoneum, or omentum. Example scenario: a 52-year-old female with refractory, localized peritoneal adhesion causing intermittent small bowel obstruction who has failed conservative management and is scheduled for diagnostic laparoscopy with lysis of atypical omental adhesions not described by a single specific code. Preoperative workflow includes history and physical, informed consent discussing potential conversion to open surgery, preoperative labs and imaging, anesthesia evaluation, and documentation of specific operative steps. Intraoperative documentation details trocar placement, laparoscopic exploration of the abdomen and peritoneal surfaces, identification of the target pathology, operative maneuvers performed (e.g., unusual omental resection, targeted lysis, or biopsy) and estimated blood loss. Postoperative workflow includes recovery room monitoring, postoperative orders, pathology submission if tissue is removed, and documentation of complications or conversion to laparotomy if occurred.
