CPT® Code 69727

Removal, entire osseointegrated implant, skull; with magnetic transcutaneous attachment to external speech processor, within the mastoid and/or involving a bony defect less than 100 sq mm surface area of bone deep to the outer cranial cortex

The procedure described by CPT® Code 69727 involves the complete removal of an entire osseointegrated implant from the skull, specifically one that is equipped with a magnetic transcutaneous attachment to an external speech processor. This type of implant, known as a bone conduction implant (BCI), is designed to amplify and conduct sound vibrations through the bone directly to the cochlea, thereby assisting individuals with hearing loss. The external speech processor is magnetically attached to the implant, which is situated beneath a thin layer of skin, allowing for a seamless integration into the patient's anatomy. Removal of the implant may be necessitated by various factors, including pain, infection, instability of the implant, trauma, or failure of the implant to properly osseointegrate with the surrounding bone. The procedure typically takes place in the mastoid region, which is located behind the ear, and may involve a bony defect that is less than 100 square millimeters in surface area, deep to the outer cranial cortex. This detailed understanding of the procedure is crucial for medical coders and billers to ensure accurate coding and billing practices.
