What 43499 covers
Code 43499 identifies an unlisted procedure involving the esophagus: the procedure performed does not have a more specific CPT code. It is selected based on the service actually performed, rather than as a substitute for a listed esophageal procedure that describes that service. Nearby listed codes address procedures such as esophageal vein ligation, repair, dilation, and transoral lower esophageal myotomy; those codes apply when their described procedure matches the work. The code is reported for the unlisted esophageal service.
Medicare assigns physician fee schedule status C, carrier priced. CMS publishes no national payment; the Medicare Administrative Contractor sets payment for each claim. The contractor also sets the global period. For multiple procedures performed in the same session, the highest-valued procedure is paid in full and the others at 50% under the stated multiple procedure rule. Report the code only for the unlisted esophageal service; select a specific esophageal code when it describes the procedure.
