What 92621 covers
An audiologist typically reports this code for additional time spent evaluating central auditory function after the initial hour. The evaluation may use behavioral listening tasks to examine how a patient processes sound, such as difficulty understanding speech in noise or distinguishing competing sounds. It is commonly performed in an outpatient audiology setting, with findings incorporated into the evaluation report.
Report 92621 only with 92620, the primary code for the initial hour of central auditory function evaluation. The additional testing time must support the units reported; document the time spent beyond the initial hour, the tests performed, and the findings. CMS classifies 92621 as an add-on code, so it is not reported by itself and payment is within the primary procedure’s global period.
