What 69729 covers
An otolaryngologist places an osseointegrated fixture in the skull for a bone-conduction hearing system, with the implant connecting to an external sound processor through intact skin. The implant’s surface area must be 100 mm² or greater. This approach may be used for patients whose hearing needs are addressed with bone-conduction sound transmission, including some patients with conductive or mixed hearing loss or single-sided deafness. The implant surgery is typically performed in an operating room or other surgical facility.
Select this code based on the transcutaneous connection and documented implant surface area, not simply the patient’s hearing diagnosis. The operative report should identify the implant and establish that its surface area meets the 100 mm² threshold. Medicare assigns 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% reduction. Modifier 50 supports bilateral reporting, paid at 150%. Assistant-at-surgery services are not paid; co-surgeons and team surgery are not permitted.
