Summary & Overview
HCPCS C9724: Endoscopic Full-Thickness Plication of Stomach (EPS)
HCPCS Level II code C9724 represents an endoscopic full-thickness plication of the stomach using an endoscopic plication system (EPS), with endoscopy included. This code captures a minimally invasive, endoluminal gastric procedure increasingly used for gastric volume reduction or structural modification without open surgery. Nationally, adoption affects outpatient procedural billing patterns, device coverage decisions, and utilization management across public and commercial payers.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of billing and coding context, payer coverage considerations, and comparative benchmarks where available. The publication summarizes clinical context for the procedure, typical sites of service, and common documentation elements relevant for claims submission.
The report also outlines what to look for in policy updates and payer medical necessity determinations that influence access and reimbursement. Where input data is incomplete, the text notes missing elements and highlights areas requiring payer-specific policy review. This serves as a concise reference for revenue cycle, clinical operations, and policy teams managing claims for endoscopic full-thickness gastric plication under HCPCS Level II code C9724.
Billing Code Overview
HCPCS Level II code C9724 describes endoscopic full-thickness plication of the stomach using an endoscopic plication system (EPS); includes endoscopy. This procedure is an endoluminal, minimally invasive gastric intervention that creates full-thickness plications in the stomach wall to alter gastric volume or configuration via an endoscopic plication device. The service type is an endoscopic therapeutic procedure (endoluminal surgical intervention). The typical site of service is the outpatient endoscopy suite or ambulatory surgery center, and it may also be performed in a hospital outpatient department depending on facility capabilities and patient factors.

Clinical & Coding Specifications
Clinical Context
A typical patient is a 38–60-year-old adult with obesity (body mass index 30–40 kg/m2) or symptomatic gastroesophageal reflux disease (GERD) seeking endoscopic, minimally invasive gastric remodeling to reduce stomach volume and improve satiety. The patient presents to an ambulatory endoscopy center after referral from primary care or bariatric clinic. Pre-procedure workup includes history and physical, laboratory evaluation as indicated, pre-anesthesia assessment, and an upper endoscopy to evaluate gastric anatomy and exclude contraindications (large hiatal hernia, severe gastritis, active ulceration). On the day of service, under monitored anesthesia care or general anesthesia, the endoscopist introduces an endoscopic plication system and performs full-thickness plication(s) of the gastric body and/or fundus to create a restrictive sleeve or plication pattern. The service includes diagnostic endoscopy components for visualization. Post-procedure the patient is recovered in the PACU with diet advancement instructions, pain control, and outpatient follow-up in the bariatric or gastroenterology clinic for weight-loss or reflux symptom monitoring. Typical sites of service are hospital outpatient departments or ambulatory surgical centers where endoscopic bariatric procedures and advanced endoscopy are performed.
