What 92604 covers

An audiologist with cochlear implant expertise uses this service to adjust the processor's program or map for a patient age 7 or older. The work may include reviewing stimulation settings across channels and making changes based on the patient's listening experience, sound tolerance, or communication needs. It is commonly performed during audiology follow-up in an outpatient clinic or implant center.

Report the code when the encounter includes reprogramming, rather than diagnostic analysis alone or a visit that only reviews device function. Documentation should identify the programming work performed, the settings changed or reviewed, and the patient's response. CMS classifies this as a therapy service, and the professional component modifier does not apply; do not append modifier 26 to represent a separate professional portion.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

92604 billing questions

How does this differ from 92603?

92604 represents processor reprogramming for a patient age 7 or older. 92603 is used for diagnostic analysis of a cochlear implant in this age group.

When should 92602 be used instead?

92602 describes cochlear implant reprogramming for a patient younger than 7. Use 92604 for patients age 7 or older.

Can modifier 26 be appended?

No. CMS identifies this as a therapy service for which the professional component modifier does not apply.

What documentation supports reporting reprogramming?

Document the programming performed, the processor settings reviewed or changed, and the patient's response or reason for the adjustment. A note describing diagnostic analysis alone supports a different service.

Is this a timed code or billed by electrode?

It is not a timed code. Report the reprogramming service, not a separate unit for each electrode or setting adjustment.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
