Summary & Overview
CPT 69728: Skull Bone–Anchored Implant Removal, Magnetically Coupled
CPT code 69728 defines surgical removal of a bone‑anchored skull implant that transmits sound energy to the inner ear via a magnetically coupled, transcutaneous speech processor and creates a bony defect of at least 100 mm². This procedure is clinically significant for patients with implanted hearing devices that require explantation due to complications, device failure, infection, extrusion, or device upgrades. Nationally, billing clarity for this code affects hospitals, ambulatory surgery centers, and specialty otologic practices managing implantable auditory hardware. Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will gain a concise summary of the clinical context and typical service settings, an overview of payer coverage considerations and common billing modifiers used with explantation procedures, and references to related procedural coding for implantable auditory devices. The publication highlights typical sites of service, procedural classification as a surgical explantation, and points that can affect claim submission such as documented bony defect size and implant coupling method. Data not available in the input is noted where payer‑specific policy details, associated taxonomies, and discrete ICD‑10 diagnoses would normally be reported.
Billing Code Overview
CPT code 69728 describes surgical removal of a bone‑anchored skull implant used to convert sound energy for reception by the inner ear. The procedure applies to implants that are not in the mastoid and involve a bony defect of 100 square millimeters or more. The implant type is a magnetically coupled, transcutaneous device paired with an external speech processor.
-
Service type: Surgical removal of bone‑anchored skull implant (device explantation)
-
Typical site of service: Operating room or ambulatory surgical center, with procedure involving the cranial/skull bone surface
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient with a previously implanted transcutaneous, magnetically coupled bone-anchored hearing implant presents with device failure and chronic extrusion around the skull implant site. After evaluation by an otolaryngologist and imaging confirming a bony defect of at least 100 mm2 at the skull implant site (not in the mastoid), the surgeon schedules operative removal of the osseointegrated skull implant. The clinical workflow includes preoperative assessment (history, audiology review, CT imaging), informed consent, perioperative antibiotics, removal of the magnet-coupled implant under general anesthesia in an ambulatory surgery center or hospital operating room, inspection and debridement of the bony defect, possible primary closure or staged reconstruction, specimen handling (if infected tissue), and postoperative wound care with audiology follow-up to consider alternative hearing rehabilitation.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | No modifier (unmodified) | Use when no special circumstances apply. |
22 | Increased procedural services | Use when the work required is substantially greater than typical due to extensive debridement or unexpected technical complexity. |
