About 92563: Pure-tone auditory decay assessment
An audiologist uses a sustained pure tone to assess auditory adaptation, reporting this diagnostic test when evaluating a patient’s hearing response over time.
An audiologist presents a steady pure tone near the patient’s hearing threshold and assesses whether the patient continues to hear it. If the tone fades from perception, the examiner adjusts its intensity and documents the response. The test is used in diagnostic audiology, often in an office or an otolaryngology practice, as part of an evaluation of hearing function and auditory adaptation. It is distinct from routine threshold testing, which measures the softest sounds a patient can detect.
Report 92563 for the tone decay testing itself. The record should identify the test performed and document the patient’s responses and findings. CMS classifies this as a technical-component-only service; a separate code covers interpretation. The code is priced as bilateral, so modifier 50 does not increase payment. Its CMS work RVU is zero, reflecting that the service’s payment is assigned to its technical component rather than professional interpretation.

92563 billing questions
How is this different from pure-tone audiometry?
Pure-tone audiometry establishes hearing thresholds. Tone decay testing assesses whether a sustained tone remains audible and how the patient responds if it fades.
Does 92563 include interpretation?
No. CMS classifies 92563 as technical-component-only, and a separate code covers interpretation.
Should modifier 50 be added for testing both ears?
The code is already priced as bilateral. Modifier 50 does not increase payment.
What documentation supports reporting 92563?
Document the tone decay test, the patient’s responses during testing, and the resulting findings. Keep interpretation distinct from the technical testing service.
Can tone decay testing be reported with other audiometry?
It may be part of a broader diagnostic hearing evaluation that also includes threshold testing. Document each service performed and report the applicable code for each.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
