A, The effect of type of hearing loss was demonstrated for a patient with conductive hearing loss tested at 2 occasions (occasion 1, permanent low-frequency hearing loss; occasion 2, temporary deterioration). WebASSR is considered to be a type of auditory evoked potential (AEP) test and currently does not have a specific CPT code. The AEP code for thresthold estimation ( 92652) is the most appropriate code for billing ASSR at this time.
