What 92603 covers

An audiologist typically performs this follow-up analysis in an audiology clinic or hospital setting for a cochlear implant user aged seven or older. The visit assesses the implant system and the patient’s response, and may include checking or adjusting processor settings as part of the diagnostic analysis. It applies to adults and children who have reached age seven.

Select this code for the age-seven-or-older diagnostic analysis with programming, rather than a subsequent reprogramming service. The record should support the patient’s age, cochlear implant status, device and auditory findings, work performed, and any programming changes. CMS classifies the service as therapy: the professional component modifier does not apply, so do not append modifier 26.

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.

92603 billing questions

How does this differ from 92604?

92603 represents diagnostic analysis with programming for a patient aged seven or older. Use 92604 for subsequent reprogramming.

Which code applies to a patient younger than seven?

Use 92601 for diagnostic analysis with programming in a patient younger than seven. Code 92602 represents subsequent reprogramming for that age group.

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 92603?

Document the patient’s age and implant status, the diagnostic assessment of the device and auditory response, and any programming performed.

Is 92603 the code for every cochlear implant follow-up?

No. The patient must be at least seven, and the service must be diagnostic analysis with programming rather than subsequent reprogramming.

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.
