Original Medicare (Parts A and B) is solid coverage for hospital stays and medical care. But many people are surprised to learn it does not cover everything, and finding that out at the dentist’s office or the eyeglass counter is not a fun way to learn it. Knowing the gaps ahead of time lets you plan for them calmly.

Below we walk through the most common things Original Medicare does not cover, and the options that exist to help fill each gap. If you want a refresher on the parts first, see our guide to Medicare Parts A, B, C, and D in plain English.

Routine dental care

Original Medicare generally does not cover routine dental care, things like cleanings, fillings, extractions, dentures, and most other dental work. This is one of the most common surprises for people new to Medicare.

To help with these costs, some people add a standalone dental plan, and some Medicare Advantage plans include certain dental benefits, which vary by plan and from year to year. It is worth checking what any given plan actually offers.

Routine vision care

Routine eye exams for glasses, and the glasses or contact lenses themselves, are generally not covered by Original Medicare. (Certain medical eye conditions may be treated differently, but routine vision care for corrective lenses is typically on you.)

As with dental, standalone vision plans exist, and some Medicare Advantage plans include vision benefits. The specifics differ from plan to plan.

Hearing care and hearing aids

Routine hearing exams and hearing aids are generally not covered by Original Medicare. Given how common hearing changes are with age, this gap surprises a lot of people. Some Medicare Advantage plans offer hearing benefits, and standalone options exist as well.

Prescription drugs (most of them)

This is a big one. Original Medicare does not include routine outpatient prescription drug coverage. To cover your everyday medications, you generally need a Medicare Part D prescription drug plan, either as a standalone plan paired with Original Medicare, or built into a Medicare Advantage plan.

Skipping drug coverage when you first become eligible can lead to a lasting late-enrollment penalty, so this is a gap worth addressing even if you take few medications today.

Long-term custodial care

Here is a gap that catches many families off guard. Original Medicare does not cover long-term custodial care, the ongoing, day-to-day help with activities like bathing, dressing, and eating that someone may need over months or years, whether at home or in a facility.

Medicare may help with short-term skilled care in specific situations, but extended custodial care is a different thing. Planning for it usually involves separate approaches, such as long-term care coverage, which is worth thinking about well before it is needed.

Care outside the United States

Original Medicare generally does not cover health care you receive while traveling outside the United States, aside from a few limited exceptions. If international travel is part of your life, this is an important gap to plan around. Some other types of coverage may help in these situations, so it is worth raising if it applies to you.

The out-of-pocket costs Original Medicare leaves behind

Beyond services it excludes entirely, Original Medicare also leaves you responsible for certain deductibles, copayments, and coinsurance, and it does not have an annual cap on what you might pay out of pocket. For some people, that open-ended exposure is the biggest gap of all.

This is exactly the gap that Medicare Supplement (Medigap) plans are designed to help with. Medigap works alongside Original Medicare to help pay some of those out-of-pocket costs. If you are comparing how to handle these costs, our look at Medicare Advantage vs. Original Medicare with Medigap walks through the two main approaches.

How people fill the gaps

Most people address these gaps in one of two broad ways:

• Original Medicare + Medigap + a Part D drug plan, often with separate dental and vision plans added on.
• A Medicare Advantage plan, which bundles coverage and may include extras like dental, vision, hearing, and drug coverage, using the plan’s network. Benefits vary by plan and year.

Neither approach is right for everyone. The best fit depends on your health, your budget, your doctors, your medications, and how you like to receive care.
