What 21080 covers
This service covers taking an impression and preparing a definitive obturator prosthesis for a patient with an acquired maxillary or palatal defect, often following maxillectomy. The custom appliance closes the opening between the oral and nasal cavities and can support speech and swallowing. A maxillofacial prosthodontist or dentist with maxillofacial prosthetic expertise typically performs the work in a dental prosthetics clinic or hospital outpatient setting. The definitive stage is generally selected after the surgical defect has healed or stabilized, rather than for an appliance used immediately after surgery or during interim healing.
Report this code for the definitive obturator service, not the surgical or interim obturator stage. Documentation should identify the defect and clinical stage and describe the impression and preparation performed. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and related postoperative care through day 90. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral adjustment is inappropriate; assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.
