Auditory osseointegrated device, external sound processor, used without osseointegration, body worn, includes headband or other means of external attachment
HCPCS code
Name of the Procedure:
Auditory Osseointegrated Device (AOD) Fitting
Common name(s): Bone Conduction Hearing Device Fitting, AOD Sound Processor Use without Implant
Summary
This procedure involves fitting an external sound processor for an auditory osseointegrated device (AOD) using a headband or another non-surgical attachment method. It's designed to help people with hearing loss who either cannot or prefer not to undergo surgical implantation.
Purpose
The primary goal of this procedure is to improve hearing for individuals with specific types of hearing loss, such as conductive or mixed hearing loss. By bypassing the ear canal and middle ear structures, the external sound processor delivers sound vibrations directly to the inner ear through the skull bones. This can enhance auditory perception and improve the overall quality of life for patients with hearing difficulties.
Indications
- Conductive hearing loss
- Mixed hearing loss
- Single-sided deafness
- Patients who are not candidates for or prefer not to undergo surgical osseointegration
- Children or adults who require a non-surgical, adjustable hearing solution
Preparation
- No specific fasting or medication adjustments are typically required.
- An audiological assessment is necessary to determine suitability and configure the device.
- A hearing aid trial might be conducted to ensure the patient benefits from bone conduction technology.
Procedure Description
- Assessment: The audiologist evaluates the patient's hearing and discusses their needs.
- Fitting: The external sound processor is placed on a headband or soft band and positioned around the patient's head.
- Testing: The device is activated and adjusted for optimal hearing performance.
- Training: The patient is instructed on how to use and care for the sound processor.
No anesthesia or sedation is required.
Duration
The entire process typically takes about 1-2 hours, including assessment, fitting, testing, and training.
Setting
This procedure is usually performed in an outpatient audiology clinic or a specialized hearing center.
Personnel
- Audiologist
- Hearing care specialist
Risks and Complications
- Skin irritation or discomfort from the headband or soft band
- Pressure headaches
- Device malfunction or need for replacement
- Limited effectiveness if not correctly aligned or fitted
Benefits
- Improved hearing with non-invasive means
- Immediate benefit upon activation of the device
- Enhanced quality of life and communication abilities
- Flexibility to remove or adjust the device as needed
Recovery
- Immediate post-procedure use with no downtime
- Regular follow-up appointments to monitor progress and make adjustments
- Daily cleaning and maintenance of the device as instructed
- Continuous wear may be recommended for optimal benefit
Alternatives
- Surgical implantation of an osseointegrated device
- Traditional hearing aids
- Middle ear implants
Pros and cons of alternatives:
- Surgical AOD: Long-term solution but involves surgical risks and recovery.
- Hearing Aids: Less specialized for conductive hearing loss but widely available and non-invasive.
- Middle Ear Implants: More invasive and generally more expensive.
Patient Experience
Patients typically experience immediate improvement in hearing once the device is activated. There might be an adjustment period to get used to the sensation of bone-conducted hearing. Pain is generally not a factor, but some may feel slight discomfort or pressure. Proper fitting and regular follow-ups can help manage and minimize any discomfort.
