What 29799 covers
Code 29799 is for a casting or strapping procedure that lacks a dedicated listed CPT code. Select it when no more specific code describes the service, rather than when a listed service specifically describes cast removal, repair, windowing, or wedging. The clinician reports the unlisted procedure, and the claim documentation should explain the body area, technique, and work performed so the Medicare contractor can assess the service.
Medicare assigns 29799 physician fee schedule status C (carrier priced): CMS publishes no national payment, and the Medicare Administrative Contractor sets payment for each claim. The contractor also determines the global period. When multiple procedures are performed in the same session, the standard multiple procedure reduction pays the highest-valued procedure in full and the others at 50%.
