Summary & Overview
CPT 43327: Partial or Complete Fundoplasty (Open Abdominal Fundoplication)
CPT code 43327 represents an open partial or complete fundoplasty (fundoplication) performed through an abdominal incision to reinforce the lower esophageal sphincter and address gastroesophageal reflux. This surgical code is clinically significant nationwide because fundoplication remains a common definitive treatment for refractory gastroesophageal reflux disease (GERD) and selected anatomical defects. The procedure’s resource use, hospital stay potential, and perioperative risk profile make accurate coding essential for clinical documentation, surgical quality measurement, and payment adjudication.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the procedure and its typical sites of service, context for clinical indications, and an outline of what to expect in payer coverage and billing practices. The publication highlights benchmarks for utilization and payment (when available), common billing considerations, and recent policy or coding clarifications that affect surgical anti-reflux procedures. The report is written for hospital billing managers, surgical practices, compliance officers, and policy analysts seeking a national perspective on coding and coverage for open fundoplication.
Billing Code Overview
CPT code 43327 describes a partial or complete fundoplasty (fundoplication) performed through an abdominal incision, in which the upper portion of the stomach is wrapped around the lower esophagus. The procedure is a surgical intervention to reinforce the lower esophageal sphincter and reduce gastroesophageal reflux.
-
Service type: Open surgical anti-reflux procedure (fundoplication)
-
Typical site of service: Inpatient or outpatient hospital operating room, or ambulatory surgical center depending on clinical indication and facility capabilities.
Clinical & Coding Specifications
Clinical Context
A 54-year-old patient with chronic gastroesophageal reflux disease (GERD) complicated by a large, symptomatic hiatal hernia and failed maximal medical therapy presents for surgical management. The patient reports persistent heartburn, regurgitation, and nocturnal symptoms despite proton pump inhibitor therapy and lifestyle modification. Preoperative workup includes upper endoscopy showing esophagitis and a sliding hiatal hernia, barium swallow documenting reflux and herniation, and esophageal manometry to assess motility. The surgical team elects to perform a partial or complete fundoplication via an open abdominal approach when anatomy, prior abdominal surgery, or intraoperative findings preclude a laparoscopic approach.
The clinical workflow includes preoperative clearance, informed consent noting risks and benefits of 43327 (open fundoplasty), anesthesia evaluation, intraoperative placement of an abdominal incision with mobilization of the gastric fundus and creation of a partial (e.g., Toupet) or complete (Nissen) wrap around the distal esophagus, and possible concurrent hiatal hernia repair. Postoperative care involves pain control, monitoring for dysphagia, early ambulation, diet advancement from clear liquids, and outpatient follow-up with symptom assessment and potential swallow study if dysphagia or leak is suspected.
