The EroScan is an effective diagnostic testing tool for otologists, audiologists and otolaryngologists that provides objective information about hearing and middle ear status with only one test. Identify outer haircell function in the cochlea, assess middle ear function and differentiate between organic and non-organic functional hearing loss. OAEs are also beneficial in assessing patients who cannot be tested by conventional means.

The EroScan’s optional database integrates tests data into Hi-Track or OZ for state tracking.Using the database also gives you a mean to create detailed, color reports in a letter-sized format that can be easily filed or faxed.You can also create a “paperless” office by saving the test results as a PDF for electronic filing or email.

CPT Codes

92587: Evoked otoacoustic emissions; limited (single stimulus level, either transient or distorted products). This is the most typical code and would be considered a “screening” code.

92588: Comprehensive or diagnostic evaluation (comparison of transient and/or distortion product otoacoustic
emissions at multiple levels and frequencies). This is for diagnostic OAE testing.
