Summary & Overview
CPT 44373: Endoscopic Conversion of Gastrostomy to Jejunostomy
CPT code 44373 represents an endoscopic evaluation of the upper gastrointestinal tract (excluding the ileum) combined with conversion of an existing gastrostomy tube to a jejunostomy tube through an abdominal approach. The procedure is clinically significant because it establishes a post-pyloric route for enteral nutrition in patients who cannot safely use gastric feeding, reducing aspiration risk and supporting nutritional needs during recovery. Nationally, this code is relevant across hospital-based and outpatient endoscopy settings where multidisciplinary teams coordinate nutritional support and procedural care.
Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise description of the clinical context and service setting, typical billing and coding considerations associated with this therapeutic endoscopic conversion, and guidance on where to find additional reimbursement and documentation resources. The publication covers expected use cases, common modifiers encountered in claims (listed separately), and benchmarking considerations for utilization and payment patterns. Data not available in the input is noted where applicable. This summary is intended for clinical administrators, coding professionals, and revenue cycle staff seeking a clear, national-level overview of CPT code 44373 and its role in enteral access management.
Billing Code Overview
CPT code 44373 describes an endoscopic examination of the upper gastrointestinal tract (excluding the ileum) followed by conversion of an existing gastrostomy tube to a jejunostomy tube via an abdominal approach. The procedure evaluates the interior structure of the esophagus, stomach, and proximal small bowel for abnormalities, then establishes a jejunostomy tube to provide enteral nutritional support until oral intake is resumed.
-
Service type: Therapeutic endoscopy with percutaneous conversion of enteric access (gastrostomy-to-jejunostomy conversion)
-
Typical site of service: Hospital operating room or endoscopy suite with abdominal access (inpatient or outpatient procedural setting)
Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with an existing gastrostomy tube who now requires postpyloric enteral access due to persistent gastric intolerance, high aspiration risk, or need for prolonged jejunal feeding. The patient commonly presents after failure of gastric feeding (vomiting, aspiration, or severe gastroparesis) or after complicated upper GI surgery. The interventional gastroenterologist or general surgeon evaluates the patient preoperatively with history, physical exam, and review of prior imaging and endoscopy. Under moderate sedation or general anesthesia in an ambulatory surgical center or hospital operating room, the provider performs upper endoscopy to examine the esophagus, stomach, and proximal duodenum, then converts the existing gastrostomy tube to a jejunostomy tube via the abdominal tract and advances it into the jejunum for enteral nutrition. Post‑procedure monitoring includes confirmation of tube position (radiograph or fluoroscopy), assessment for immediate complications (bleeding, infection, tube dislodgement, or bowel injury), and initiation of jejunal feeding per nutrition orders once position and tolerance are confirmed. Typical sites of service are the hospital operating room, ambulatory surgical center, or endoscopy suite depending on patient acuity and anesthesia requirements.
