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.
