Summary & Overview
HCPCS M0100: Intragastric Hypothermia Using Gastric Freezing
HCPCS Level II code M0100 denotes intragastric hypothermia using gastric freezing, a procedural therapeutic intervention that cools the stomach via endoscopic or intragastric means. The code is relevant nationally as a specialized procedural identifier supporting billing and tracking of gastric cooling therapies used in select clinical scenarios. It enables payers and providers to categorize and reimburse a distinct intragastric therapeutic service.
Key payers included in the analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare and Medicare. Readers will find a concise description of the clinical service and the typical sites where the procedure is performed (endoscopy suites, operating rooms, inpatient or outpatient settings). The publication outlines expected benchmarking topics and policy considerations: coding and billing context, how M0100 is positioned among HCPCS Level II procedures, and clinical context for intragastric hypothermia use. Where available, the piece addresses reimbursement benchmarks, common modifier usage, and potential documentation considerations.

Billing Code Overview
HCPCS Level II code M0100 describes intragastric hypothermia using gastric freezing, a procedural service that involves cooling the stomach through endoscopic or intragastric techniques to induce localized hypothermia. The service type is a therapeutic intragastric procedure aimed at targeted gastric cooling for clinical indications where gastric hypothermia is applied. The typical site of service for this procedure is an inpatient or outpatient endoscopy suite or an operating room where endoscopic or minimally invasive intragastric therapies are performed.

Clinical & Coding Specifications
Clinical Context
A typical patient for M0100 (intragastric hypothermia using gastric freezing) is an adult with severe hypermetabolic state, refractory intracranial hypertension with elevated core temperature, or select post-cardiac arrest patients for targeted temperature modulation when intragastric cooling is chosen. The patient is evaluated by the critical care team and/or interventional gastroenterology or critical care proceduralist. Pre-procedure assessment includes review of indications, contraindications, coagulation status, and recent imaging or endoscopy as appropriate. The procedure is performed in an inpatient setting — commonly an intensive care unit or a monitored procedural suite — under moderate sedation or general anesthesia depending on patient stability. A nasogastric or orogastric approach is used to position the gastric cooling device under direct visualization or with imaging guidance; device activation achieves controlled intragastric hypothermia. Continuous monitoring of core temperature, hemodynamics, and potential complications (bleeding, aspiration, gastric mucosal injury) occurs during therapy. Documentation includes indication, informed consent, device type, insertion method, sedation/anesthesia, temperature targets and duration, any adjunctive measures, and post-procedure plan for device removal and rewarming protocols.
