Original Medicare (Parts A and B) does not cover hearing aids or the fitting exams needed to select and adjust them. This has been true for decades and remains one of the most significant gaps in Original Medicare coverage. If you need hearing aids, you will generally pay the full retail cost out of pocket under traditional Medicare, which can run from several hundred to several thousand dollars per device.
Medicare Part B does cover diagnostic hearing and balance exams, but only when your doctor orders the test to diagnose a specific medical condition, such as sudden hearing loss, dizziness, ringing in the ears, or an infection affecting the ear. In that case, you pay the standard 20% coinsurance after meeting your Part B deductible, and the test must be considered medically necessary rather than a routine screening. Routine hearing tests done simply to see whether you need a hearing aid are not covered by Original Medicare.
Many Medicare Advantage plans (Part C) offer hearing benefits that Original Medicare does not, including routine hearing exams and an allowance toward hearing aids. Coverage varies widely by plan and insurer: some include a modest annual allowance, others partner with specific hearing aid networks offering discounted devices, and some cover only one exam per year with little or no hardware benefit. Before enrolling in or switching to a Medicare Advantage plan for hearing coverage, read the plan's Evidence of Coverage document carefully to see exact dollar limits, network restrictions, and whether both ears are covered.
If you have Original Medicare and no supplemental hearing benefit, there are still ways to lower your costs. Some community health centers, university audiology programs, and veterans' services offer reduced-cost or free hearing aids. Nonprofit organizations and state assistance programs sometimes provide grants or low-interest financing for hearing devices. Over-the-counter hearing aids, now sold without a prescription for adults with mild to moderate hearing loss, are typically far cheaper than prescription devices and may be a reasonable option for some people, though they are not covered by Medicare either.
Medigap (Medicare Supplement) policies generally do not add hearing aid coverage; they only help pay the coinsurance and deductibles for services Medicare already covers, such as a medically necessary diagnostic hearing test. So pairing Original Medicare with a Medigap plan will not solve the hearing aid cost problem.
If hearing aids are a priority, the most direct path is to compare Medicare Advantage plans in your area during the annual enrollment period, specifically checking the hearing benefit details, not just whether a hearing benefit "exists." Two plans can both advertise hearing coverage while offering very different real-world value. A licensed insurance broker who sells multiple Medicare Advantage plans, or your State Health Insurance Assistance Program (SHIP) counselor, can help you compare the actual hearing allowances side by side at no cost to you.
