Definition
An audiologist/hearing aid fitter is the professional who specializes in evaluating and treating people with hearing loss, conducts a wide variety of tests to determine the exact nature of an individual's hearing problem, presents a variety of treatment options to patients, dispenses and fits hearing aids, administers tests of balance to evaluate dizziness and provides hearing rehabilitation training. This classification should be used where individuals are licensed as "audiologist-hearing aid fitters" as opposed to states that license individuals as "audiologists".

- Group: Speech, Language and Hearing Service Providers — code 4 of 9 in the group
- Classification: Audiologist-Hearing Aid Fitter 237600000X
Audiologist-Hearing Aid Fitter has no specializations, so 237600000X is the only code for it. A provider may report more than one taxonomy code on an NPI but marks one as primary.
Medicare
237600000X has no entry in the CMS Medicare Provider and Supplier Taxonomy Crosswalk. That usually means Medicare does not enroll this kind of provider under its own specialty — the provider can still hold an NPI and use this code on claims to other payers.

The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
