CPT 43773: Laparoscopic or Open Biliary/Pancreatic Duct Procedure

CPT code 43773 denotes a specialized surgical procedure involving the biliary or pancreatic ductal system performed via laparoscopic or open abdominal techniques. Nationally, this code captures resource use for complex gastrointestinal surgeries and informs hospital and ambulatory surgical center billing for operative interventions. Accurate coding of 43773 matters for clinical documentation, procedure tracking, and payer adjudication.

Clinical & Coding Specifications

Clinical Context

A 68-year-old patient with symptomatic gastroparesis presents to the gastroenterology service for placement of a percutaneous endoscopic gastrostomy with jejunal extension (PEG-J) to provide enteral nutrition and facilitate gastric decompression. The patient has failed oral and nasoenteric feeding trials and has recurrent vomiting with aspiration risk. The interventional endoscopy team performs the procedure in an endoscopy suite or ambulatory surgery center under monitored anesthesia care. The workflow includes pre-procedure consent and history, brief pre-op assessment, administration of sedation or anesthesia, endoscopic placement of the gastrostomy tube followed by advancement of a jejunal feeding extension, verification of position fluoroscopically or endoscopically, securement of the tube, and post-procedure recovery with discharge instructions for tube care and nutrition plan.

Taxonomy Code	Specialty	Notes
208600000X	Gastroenterology	Interventional gastroenterologists commonly perform PEG-J placement.
207L00000X	General Surgery	General surgeons perform PEG and feeding tube placements in operative settings.
363LP0800X	Advanced Gastrointestinal Endoscopy	Endoscopists with advanced endoscopy training perform complex enteric tube placements.
208M00000X	Colon & Rectal Surgery	May be involved when lower GI access or complex anatomy requires surgical input.
207K00000X	Otolaryngology	Occasionally involved when airway/aspiration risk necessitates ENT evaluation or combined procedures.

CPT Code	Description	Relationship to This Procedure
`43246`	Endoscopic placement of percutaneous gastrostomy tube, percutaneous endoscopic gastrostomy (PEG)	Often billed when PEG placement is performed without jejunal extension; foundational step for PEG-J.
`49440`	Insertion of tunneled intraperitoneal catheter, without subcutaneous reservoir (e.g., peritoneal dialysis catheter)	Alternate enteric access procedure when peritoneal or surgical access is required; listed for care planning when PEG-J is not feasible.
`45385`	Colonoscopy, flexible; with biopsy, single or multiple	May be performed in the same endoscopy suite by gastroenterology for concurrent lower endoscopy needs, billed separately.
`43239`	Upper GI endoscopy, diagnostic, with biopsy, single or multiple	Diagnostic upper endoscopy codes used when diagnostic assessment is performed prior to or during tube placement.
`49422`	Replacement or change of gastrostomy tube, percutaneous, without imaging	Used for subsequent exchanges or replacements of PEG-J tubes in outpatient settings.
