In most cases, Medicare does not cover hearing health care, with a few exceptions. Up to 80 percent of diagnostic hearing and balance exams costs may be covered if your primary healthcare provider recommends the need for the exam. Hearing tests, hearing aids, and hearing aid fittings are not covered under Medicare A or B. If you have a Medicare Advantage plan (Medicare Part C), you may be covered for hearing tests and hearing aids. As each Medicare Advantage plan is different, it’s important to check your individual plan to see if hearing health is covered.
