Otolaryngology & Audiology
OAEs are an integral part of hearing assessment. OAEs are fast, noninvasive,
cost-effective and have valuable diagnostic implications for patient treatment.
Advantages of OAEs
-
OAEs give information about hearing and middle ear status with only one test
-
OAEs are objective
-
No response is required from the patient
-
Effective with difficult-to-test patients
-
OAEs can be performed by office personnel
High-frequency DPOAEs
Measurements may prove useful for:
-
Monitoring Ototoxicity in young patients
-
Prospective studies of noise-induced hearing loss
-
Obtaining scientific data on the effect of aging on DPOAEs
Otolaryngology & Audiology
Uses
-
Monitor middle ear pathology post PE tube insertion
-
Rule out retrocochlear pathology
-
Differentiate peripheral from central auditory disorders
-
Monitor effects of ototoxic medications and occupational noise exposure
-
Use in conjunction with high frequency audiometry
-
Screen both ears of infants and toddlers
-
Evaluate difficult-to-test and developmentally disabled patients
-
Identify suspected non-organic hearing loss
-
Community hearing screenings
Reimbursement
OAE tests can be billed under two CPT codes. The ERO•SCAN test protocol
determines which code to use.
-
92587
Evoked otoacoustic emissions; limited (single stimulus level, either transient
or distortion products)
-
92588
Comprehensive or diagnostic evaluation (comparison of transient and/or
distortion product otoacoustic emissions at multiple levels and frequencies)

ERO•SCAN's noise rejection algorithm is the most
effective on the market allowing for reliable testing in up to 70 dB SPL of
background noise.
