What 92558 covers
92558 identifies an automated otoacoustic-emissions hearing screen, rather than a diagnostic evaluation. A probe placed in the ear canal presents sound and records emissions generated by the inner ear; the screening result indicates whether further hearing assessment may be needed. Audiologists and hearing-screening programs use this method, including in newborn hearing-screening workflows.
Medicare assigns 92558 physician fee schedule status X, a statutory exclusion because it is not a physician service under the Medicare statute. The physician fee schedule does not pay it; when covered, Medicare payment comes through another fee schedule or payment system. It is distinct from diagnostic otoacoustic-emissions services and from pure-tone screening. Report it for the automated screening service, not as a comprehensive audiologic evaluation.
