Requires health benefits coverage of hearing aids and cochlear implants for insureds aged 21 or younger.

S 164 requires health insurance plans in New Jersey to cover medically necessary hearing aids (for each ear) and cochlear implants for insured individuals under age 21. It applies to hospital service, medical service, health service corporation contracts, and individual health insurance policies. Insurers must cover the full cost of cochlear implant procedures and devices, while limiting hearing aid coverage to $1,000 per hearing aid per ear every 24 months - allowing patients to pay the difference for more expensive devices without penalty. This bill directly affects families of children and young adults needing hearing devices, ensuring insurance coverage for essential hearing healthcare under 21.
