The general rule for routine care
Original Medicare does not cover every health-related service. Medicare.gov lists most routine dental care, routine eye exams for prescription glasses, hearing aids, and hearing-aid fitting exams among the items Original Medicare generally does not cover.
That does not mean Medicare never pays for any care involving the teeth, eyes, or ears. Coverage can depend on why the service is needed, whether it is medically necessary, who orders or provides it, and whether the service meets a specific Part A or Part B rule.
Routine care and medically necessary diagnostic or treatment services are not the same thing. Confirm the exact service—not only the body part involved.
Dental: most routine services are outside Original Medicare
Medicare.gov says Original Medicare generally does not cover routine cleanings, fillings, tooth extractions, dentures, or dental implants. A person usually pays the full cost unless another source of coverage applies.
Medicare may cover certain dental services when they are inextricably linked to a covered medical treatment, such as specified services connected with an organ transplant, cardiac valve procedure, certain cancer treatment, or dialysis for end-stage renal disease. The official coverage rules and the facts of the treatment control; a dental diagnosis alone does not establish Medicare coverage.
Vision: routine refractions are different from medical eye care
Original Medicare generally does not cover routine eye refractions for eyeglasses or contact lenses. Part B may cover one pair of standard-frame eyeglasses or contact lenses after cataract surgery that implants an intraocular lens, when Medicare's requirements are met.
Part B may also cover certain eye services for eligible people, including diabetic retinopathy exams, glaucoma screenings for people at high risk, and certain tests and treatments for age-related macular degeneration. Frequency, provider, medical-necessity, deductible, and coinsurance rules may apply.
Hearing: diagnostic exams are not hearing-aid coverage
Part B covers diagnostic hearing and balance exams when a physician or other qualified health care provider orders them to determine whether medical treatment is needed. Medicare also allows limited direct access to an audiologist once every 12 months for certain diagnostic services described by Medicare.
Original Medicare does not cover hearing aids or exams for fitting hearing aids. A covered diagnostic test should not be mistaken for coverage of the device itself.
Where other coverage may enter the picture
Some Medicare Advantage plans offer extra dental, vision, or hearing benefits that Original Medicare does not cover. Benefits, provider or vendor networks, covered services, allowances, frequency limits, authorization rules, and member costs can differ by plan and can change from one year to the next.
Medigap policies generally help with a person's share of costs for services Original Medicare covers. Medicare.gov says Medigap generally does not cover routine dental or vision care, hearing aids, or glasses. Employer or retiree coverage, Medicaid, veterans' benefits, and separate insurance may also affect the gap, depending on individual eligibility and program rules.
