Hearing Aids (CPB 0612, reviewed 2026-03-02)
Summary
Aetna's Clinical Policy Bulletin 0612 covers air conduction, implantable and semi-implantable hearing aids. Air conduction hearing aids are medically necessary when hearing thresholds are 40 dB HL or greater at 500, 1000, 2000, 3000, or 4000 Hz, 26 dB HL or greater at three of these frequencies, or speech recognition is less than 94 percent, and bilateral aids are medically necessary when these thresholds are met in each ear. Implantable and semi-implantable hearing aids are medically necessary for members with moderate-to-severe sensorineural hearing impairment who cannot tolerate an ear mold because of medical conditions such as auricular atresia or severe chronic otitis externa, while air conduction hearing aids for balance, cartilage conduction hearing aids, and hearing aids for all other indications, including depression and cognitive decline in the elderly, are considered experimental, investigational, or unproven.
