Name of the Procedure:

Audiometry for Hearing Aid Evaluation
HCPCS Code: S0618

Summary

Audiometry for hearing aid evaluation is a diagnostic test used to determine the level and degree of hearing loss. During the test, patients listen to a variety of sounds and tones, helping audiologists to assess their hearing ability and decide on the appropriate hearing aid solutions.

Purpose

The primary purpose of audiometry for hearing aid evaluation is to diagnose the degree and type of hearing loss in patients. The outcome helps in fitting the right hearing aid to improve patient quality of life through better hearing.

Indications

• Difficulty hearing conversations
• Frequent need to increase volume on electronic devices
• Experiencing ringing in the ears (tinnitus)
• Family history of hearing loss
• Exposure to high levels of noise

Preparation

• No fasting or significant preparation is usually required.
• Patients should avoid loud noise exposure 24 hours before the test.
• Bring a list of all current medications.
• Inform the audiologist of any recent ear infections or other ear-related problems.

Procedure Description

1. Initial Assessment: The audiologist reviews the patient's medical history and symptoms.
2. Otoscopy: Visual examination of the ear canal and eardrum.
3. Pure-Tone Audiometry: The patient wears headphones and listens to tones at various pitches and volumes, indicating when they can hear each sound.
4. Speech Audiometry: The patient repeats words presented at different volume levels.
5. Impedance Testing: Assesses the movement of the eardrum in response to pressure changes.
6. Results Discussion: The audiologist reviews the results, determining the degree of hearing loss and recommending suitable hearing aids if necessary.

Duration

The procedure typically takes about 30 to 60 minutes.

Setting

• Outpatient clinic
• Audiology center
• ENT (Ear, Nose, and Throat) specialist's office

Personnel

• Audiologist
• Audiology assistant (in some cases)

Risks and Complications

• Generally a non-invasive and low-risk procedure
• Rare discomfort from the headphones or ear inserts
• Occasionally, earwax or foreign objects may need to be removed before testing

Benefits

• Accurate assessment of hearing loss
• Customized hearing aid recommendations
• Improved hearing ability
• Better overall quality of life from increased hearing capabilities

Recovery

• No significant recovery period is required.
• Patients can immediately resume regular activities.
• Follow-up appointments may be scheduled to fit and adjust hearing aids.

Alternatives

• Tympanometry: Measures ear function and pressure.
• Extended high-frequency audiometry: Tests higher frequencies beyond standard audiometry.
• Otoacoustic emissions testing: Assesses inner ear hair cell function.

Pros and Cons:

• Pros of Alternatives: Some might be quicker or provide different diagnostic information.
• Cons of Alternatives: May not fully assess hearing loss extent or help in fitting hearing aids.

Patient Experience

• The patient may experience minimal discomfort from wearing headphones or ear inserts.
• No pain should be experienced during the procedure.
• If any discomfort arises, it is usually temporary and subsides after the test.
• Clear communication from the audiologist can help alleviate any anxiety about the procedure.
