Official Description

Implantation, osseointegrated implant, temporal bone, with percutaneous attachment to external speech processor/cochlear stimulator; with mastoidectomy

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

An osseointegrated implant is a specialized device that is surgically placed in the temporal bone of the skull. This procedure involves the attachment of the implant to an external speech processor or cochlear stimulator through a percutaneous method, which means that the attachment occurs through the skin. The primary purpose of this type of implant is to restore hearing in individuals who experience hearing loss due to conditions affecting the middle ear and cochlea. The procedure begins with careful measurement and marking of the skin over the intended implantation site to ensure optimal placement of the implant. Following this, an incision is made in the skin to expose the mastoid complex, which is the area of bone located behind the ear. During the surgery, skin and periosteal flaps are created to provide access to the bone. A pilot hole is then drilled into the temporal bone, which is gradually enlarged to accommodate the implant. Once the site is prepared, the implant is securely placed into the bone. The skin flap is then perforated to facilitate the connection to the external speech processor or cochlear stimulator. After the implant is in place, the surrounding soft tissues are reduced in thickness to ensure a proper fit before the wound is closed. It is important to note that this specific procedure, identified by CPT® Code 69715, includes a mastoidectomy, which involves the removal of infected and diseased air cells from the mastoid area, allowing for better exposure of non-aerated segments of the mastoid prior to the implantation of the device. This distinguishes it from similar procedures, such as CPT® Code 69714, where the mastoidectomy is not performed.

1. Indications

The procedure described by CPT® Code 69715 is indicated for patients who have experienced hearing loss due to specific conditions affecting the middle ear and cochlea. The following are the explicit indications for performing this procedure:

  • Hearing Loss - Patients suffering from hearing loss that is attributed to diseases affecting the middle ear and cochlea.
  • Infection or Disease in the Mastoid Area - Conditions that necessitate the removal of infected or diseased air cells in the mastoid region.
  • Need for Osseointegrated Implant - Patients who require an osseointegrated implant to restore hearing functionality.

2. Procedure

The procedure for CPT® Code 69715 involves several critical steps that ensure the successful implantation of the osseointegrated device. Each step is detailed as follows:

  • Step 1: Skin Measurement and Marking - The surgical process begins with the careful measurement and marking of the skin over the planned implantation site. This step is crucial for determining the optimal placement of the implant, ensuring that it is positioned correctly for effective function.
  • Step 2: Incision and Exposure - Following the marking, an incision is made in the skin to expose the mastoid complex. This area is located behind the ear and is essential for accessing the temporal bone where the implant will be placed.
  • Step 3: Creation of Flaps - Skin and periosteal flaps are created to provide adequate access to the underlying bone. These flaps allow the surgeon to work effectively in the surgical area without compromising the surrounding tissues.
  • Step 4: Drilling the Pilot Hole - A pilot hole is drilled into the temporal bone, which is then gradually enlarged to accommodate the osseointegrated implant. This step requires precision to ensure that the implant fits securely within the bone.
  • Step 5: Implant Placement - Once the site is adequately prepared, the osseointegrated implant is placed into the drilled opening. The implant must be secured properly to ensure stability and functionality.
  • Step 6: Perforation of Skin Flap - The skin flap is perforated to allow for the attachment of the external speech processor or cochlear stimulator. This connection is vital for the device to function effectively in restoring hearing.
  • Step 7: Soft Tissue Reduction and Wound Closure - The surrounding soft tissues are then reduced in thickness to ensure a proper fit over the implant. Finally, the wound is closed, completing the surgical procedure.

3. Post-Procedure

After the completion of the procedure, patients may require specific post-operative care to ensure proper healing and functionality of the implant. This includes monitoring for any signs of infection at the surgical site, managing pain, and following up with audiological assessments to evaluate the effectiveness of the implant. Patients may also need to adhere to specific guidelines regarding activity restrictions and care of the surgical area to promote optimal recovery. Regular follow-up appointments will be necessary to assess the integration of the implant and the performance of the external speech processor or cochlear stimulator.
