What 21086 covers
This service covers taking the impression and preparing a custom prosthesis to replace an external ear. It is used when an auricle is absent or has been removed, such as after cancer surgery or traumatic injury. A maxillofacial prosthodontist or another qualified clinician may perform the work, commonly in an office-based prosthetic practice. The service addresses the ear specifically, rather than an orbital, nasal, or broader facial defect.
Report 21086 for the auricular prosthesis impression and preparation service, supported by documentation of the affected site and the work performed. CMS assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 identifies bilateral work and is paid at 150%. An assistant at surgery is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.
