Summary & Overview
CPT 43320: Plastic Repair of Lower Esophagus and Upper Stomach
CPT code 43320 denotes an open surgical plastic repair of the lower esophagus and upper stomach performed via an abdominal or thoracic incision. This code captures operative management of structural abnormalities at the gastroesophageal junction, a procedure with implications for surgical quality, inpatient resource use and postoperative care. Nationally, it matters for reimbursement classification, surgical registry reporting and clinical coding accuracy.
Key payers addressed in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Readers will find a concise explanation of the procedure and its typical clinical setting, comparisons of payer coverage patterns where available, common modifier usage, and links to relevant coding guidance. The summary highlights expected sites of service (hospital operating room, typically inpatient) and the service line (surgical gastroenterology/upper GI).
This publication provides benchmarks and policy-relevant context for coding and billing teams, clinical documentation specialists, and revenue cycle managers. It also outlines where data is available and where input fields are missing for deeper payer-specific analysis.
Billing Code Overview
CPT code 43320 describes a surgical procedure involving plastic repair of the lower esophagus and upper stomach performed through an incision in the abdomen or chest. This procedure is a form of open surgical repair of the gastroesophageal junction intended to correct structural defects that affect the lower esophageal sphincter or proximal stomach.
Service type: Surgical — open abdominal or thoracic gastrointestinal surgery
Typical site of service: Inpatient or outpatient hospital operating room
Clinical & Coding Specifications
Clinical Context
A typical patient is a 52-year-old with symptomatic hiatal hernia and severe gastroesophageal reflux disease (GERD) refractory to medical therapy who presents for elective surgical repair. Preoperative evaluation includes upper endoscopy, esophagram, and esophageal manometry to assess anatomy and motility. The surgeon plans an open or transthoracic approach for plastic repair of the lower esophagus and upper stomach when minimally invasive repair is contraindicated due to prior abdominal surgery, dense adhesions, complex paraesophageal hernia, or intraoperative findings requiring conversion. The clinical workflow includes preoperative optimization, informed consent, general anesthesia, intraoperative placement of nasogastric tube for decompression, reduction of herniated stomach, cruroplasty and fundoplication or gastropexy as indicated, hemostasis, and layered closure. Postoperative care includes pain control, respiratory support as needed, early ambulation, diet advancement from clear liquids to soft diet, and outpatient follow-up for symptom assessment and imaging if persistent dysphagia or leak is suspected. Typical sites of service are the hospital operating room or ambulatory surgical center when the patient meets ASC criteria. Service type: major surgical procedure (open trunk surgery). Typical patient scenario: elective or urgent open repair of a complex hiatal hernia or refractory GERD where thoracic or abdominal incision is required to reconstruct the esophagogastric junction.
