DESCRIPTION
Evoked otoacoustic emissions involve the measurement of sounds in the external ear canal that reflect the working of the cochlea. A probe and click stimuli is utilized in the performance of this test. OAE is considered a standard battery test used to screen for hearing impairment in infants. It is considered a specialized test when used to test for hearing impairment in adults and children.
POLICY
Evoked otoacoustic emissions used to screen for hearing impairment in infants (birth through 24 months) is considered medically necessary.
Evoked otoacoustic emissions used to test for hearing impairment in adults and children is considered medically necessary if the medical appropriateness criteria are met. (See Medical Appropriateness below.)
MEDICAL APPROPRIATENESS
Evoked otoacoustic emissions testing is considered medically appropriate for adults and children when the initial diagnostic tests are inconclusive or with illnesses or injuries including, but not limited to, the following:
Bacterial meningitis
Cochlear otosclerosis
Congenital anomalies
Exposure to intense noise
Facial nerve paralysis (Bell's Palsy)
Fractures of the temporal bone or trauma affecting the central auditory pathways
Hearing loss
Labyrinthitis
Ménière's disease
Neoplasms of the auditory or central nervous system
Otitis media
Ototoxic drugs
Surgery involving the auditory and/or central nervous system (e.g., skull-based tumors such as acoustic neuroma and meningioma)
Tinnitus
Vertigo
ADDITIONAL INFORMATION
The following screening program for infants is recommended by the American Academy of Pediatrics 2007 Position Statement:
Begin screening for hearing loss no later than one month of age
Include a comprehensive audiological evaluation before three months of age for infants who fail the initial screen
Refer infants with confirmed hearing loss for age-appropriate diagnostic testing before six months of age
Refer infants for effective intervention by qualified professionals with an expertise in hearing loss and deafness in infants and children
Well-child visits should Include ongoing surveillance of communicative development beginning at two months of age regardless of previous hearing-screening outcomes or the presence of risk factors
