Oral and maxillofacial surgery
About 21110: Interdental fixation for nonfracture conditions
Reports placement of an interdental fixation device to stabilize the dental arches for a condition other than a fracture or dislocation.
An oral and maxillofacial surgeon or another qualified surgeon places a device that secures the teeth of opposing arches to restrict jaw movement. The defining distinction is the indication: this service is for a condition other than a fracture or dislocation. Documentation should identify the condition, the purpose of stabilization, and the device placement; a mandibular fracture treated with fixation belongs to the fracture-treatment codes instead.
Report 21110 for the fixation service supported by the operative record. It has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
