Deductibles, copays, and coinsurance. Costs for covered services can add up, and — unlike most private insurance — there is no annual out-of-pocket maximum. Medicare Advantage and Medigap plans may pay all or a percentage of these costs and may include an out-of-pocket maximum.
Prescription drugs. For coverage, you need to enroll in a Part D prescription drug plan or a Medicare Advantage plan that includes drug coverage.
Dental and vision care. Original Medicare does not cover routine dental or vision care. Some Medicare Advantage and Medigap plans may offer coverage for either or both of these needs. You might also consider private dental and/or vision insurance.
Hearing care and hearing aids. Some Medicare Advantage plans may cover hearing aids and exams.
Medical care outside the United States. Original Medicare does not offer coverage outside the United States. Some Medicare Advantage and Medigap plans offer coverage for emergency care abroad. You can also purchase a private travel insurance policy.
Long-term care. Medicare does not cover "custodial care" in a nursing home or home health care. You may be able to purchase long-term care (LTC) insurance from private insurers.
A complete statement of coverage, including exclusions, exceptions, and limitations, is found only in the LTC insurance policy. It should be noted that LTC insurance carriers have the discretion to raise their rates and remove their products from the marketplace.
