Policy Summary
Aetna considers intragastric hypothermia (gastric freezing; HCPCS M0100) experimental/investigational and not covered for chronic peptic ulcer disease (ICD-10 K27.4–K27.9) or any other indication due to insufficient evidence, high complication rates, and lack of demonstrated effectiveness. There are no coverage exceptions or requirements — CMS regards the procedure as obsolete and it is not covered for any indication.
