Medicare Coverage | 7 Gaps You Need to Know About

What Doesn’t Medicare Cover?

Direct answer: Medicare is comprehensive for hospital and medical care, but it has real, well-defined gaps: prescription drugs, routine dental care, routine vision care, hearing exams and hearing aids, comprehensive annual physicals, long-term custodial care, and care outside the United States. Each gap has a way to fill it — through Part D, Medicare Advantage, Medigap, or standalone insurance — but none of them are covered automatically just because you have Original Medicare. Knowing these gaps before you need care is what prevents an expensive surprise.

Gap 1: Prescription Drugs

Original Medicare Parts A and B handle a great deal, but outpatient prescription medications aren’t part of that coverage. If you assume Medicare has your prescriptions covered by default, that’s the surprise waiting at the pharmacy counter. Part D prescription drug plans exist specifically to fill this gap, either as a standalone plan alongside Original Medicare or bundled into a Medicare Advantage plan.

Gap 2: Dental Care

Routine dental care isn’t part of Original Medicare — no coverage for checkups, cleanings, X-rays, fillings, root canals, extractions, implants, bridges, or dentures. Medicare does cover dental care in narrow, specific medical scenarios (like clearing an infection before certain surgeries), but that’s a far cry from routine care. A standalone dental plan or a Medicare Advantage plan with dental benefits are the two main paths to filling this gap.

Gap 3: Vision Care

Original Medicare handles serious eye conditions well — cataracts, glaucoma, and similar medically necessary treatment are covered. But routine eye exams, eyeglasses, and contact lenses fall outside that coverage entirely. Some Medicare Advantage plans include modest vision benefits, or you can pay directly for routine vision care out of pocket.

Gap 4: Hearing Exams and Hearing Aids

Original Medicare covers medically necessary care related to hearing-related medical conditions, but routine hearing exams and hearing aids themselves aren’t covered. As with dental and vision, Medicare Advantage plans are the primary route to hearing aid coverage, with benefits varying significantly by plan.

Gap 5: A Comprehensive Annual Physical

This one surprises a lot of people. Original Medicare covers an annual “wellness” visit, which is focused on updating your personalized prevention plan and screening for specific risk factors — it’s genuinely useful, but it isn’t the same as a comprehensive head-to-toe physical exam. If you’re expecting the kind of full physical you might remember from before Medicare, that’s not what this visit is designed to be.

Gap 6: Nursing Homes and Long-Term Care

This is where the gap gets financially serious. Medicare covers skilled nursing facility care, but only under specific conditions and for a limited time — and under standard Original Medicare rules, that generally requires a qualifying inpatient hospital stay of at least three consecutive days first. There are some exceptions to this rule now: certain Accountable Care Organizations have an approved waiver, and a newer CMS demonstration program waives the requirement for a small set of specific procedures. Medicare Advantage plans are also permitted to waive the three-day requirement, and many do — so this rule genuinely differs depending on your coverage type, which is worth confirming directly with your plan or hospital rather than assuming.

Even when skilled nursing coverage applies, it’s not an open-ended benefit — coverage is capped, and it isn’t designed for indefinite stays.

Custodial care — help with daily living activities like bathing, eating, and dressing — isn’t covered at all, regardless of how it’s structured. This is the single biggest gap on this list in terms of financial risk. Long-term care simply isn’t something Medicare pays for, so budgeting, saving, or considering long-term care insurance is a separate planning conversation entirely.

Gap 7: Care Outside the United States

Original Medicare generally doesn’t cover care received outside the U.S., except in a small number of narrow, specific circumstances. If you need medical care while traveling internationally, you could be responsible for the full cost yourself.

Some Medigap plans include foreign travel emergency coverage up to plan limits, which can be a meaningful safety net if you travel internationally. Otherwise, a separate travel insurance policy is worth considering for genuine peace of mind.

Bottom Line

None of this means Medicare falls short as coverage — it handles hospital and medical care well, and these seven gaps are specific, well-known, and entirely plannable around once you know they exist. Whether you stay with Original Medicare and add a Medigap Supplement plus a Part D plan, or choose a Medicare Advantage plan with built-in extra benefits, understanding these gaps ahead of time is what turns a potential financial surprise into a manageable, informed decision.

Key Takeaways

• Original Medicare doesn’t cover outpatient prescription drugs, routine dental care, routine vision care, routine hearing exams or hearing aids, comprehensive physicals, long-term custodial care, or most care outside the U.S.
• Part D plans, Medicare Advantage plans, Medigap, and standalone insurance each fill different combinations of these gaps.
• Medicare’s “wellness visit” is not the same as a comprehensive annual physical exam.
• Skilled nursing facility coverage generally requires a qualifying three-day hospital stay under standard Original Medicare rules, though exceptions now exist through certain ACO waivers and newer CMS demonstration programs, and many Medicare Advantage plans waive the requirement entirely.
• Custodial long-term care is never covered by Medicare, making it the most financially significant gap on this list.
• Some Medigap plans offer foreign travel emergency coverage, but Original Medicare itself generally doesn’t cover care outside the U.S.

FAQ – Things Medicare Doesn’t Cover

Does Medicare cover prescription drugs?
Not through Original Medicare directly. You need a separate Part D plan, either standalone or bundled into a Medicare Advantage plan.

Does Medicare cover dental, vision, or hearing care?
Only in narrow, medically necessary circumstances. Routine dental, vision, and hearing care all require separate coverage through Medicare Advantage or standalone insurance.

Does Medicare cover an annual physical exam?
Not a comprehensive physical. Medicare covers an annual wellness visit focused on prevention planning and risk screening, which is more limited than a traditional full physical.

Does Medicare cover nursing home care?
Only skilled nursing facility care under specific conditions and for a limited time — not long-term custodial care, which Medicare never covers.

Do I need a three-day hospital stay before Medicare covers skilled nursing care?
Generally yes, under standard Original Medicare rules, though exceptions exist through certain ACO waivers, some newer CMS demonstration programs, and many Medicare Advantage plans, which are permitted to waive this requirement.

Does Medicare cover care when I travel internationally?
Generally no, except in narrow, specific circumstances. Some Medigap plans include foreign travel emergency coverage, or you can purchase separate travel insurance.

How do I fill these Medicare coverage gaps?
Through a combination of a Part D plan, Medigap Supplement, or a Medicare Advantage plan with added benefits — the right combination depends on which gaps matter most to your situation.

Does Medicare Cover Hearing Aids? | The Surprising Truth

Does Medicare Cover Hearing Aids?

Direct answer: Original Medicare (Parts A and B) does not cover routine hearing exams, hearing aids, or fittings — and a Medigap Supplement doesn’t add this coverage either, since Medigap only supplements what Original Medicare already covers. If hearing aid coverage matters to you, a Medicare Advantage plan is generally the path to it, but coverage varies enormously between plans — from a modest discount program to comprehensive coverage of premium devices. Knowing exactly what to check before enrolling is what separates a plan that actually meets your needs from one that looks good in a brochure but falls short when you need it.

Why Doesn’t Original Medicare or Medigap Cover Hearing Aids?

This surprises a lot of people, especially those who assume Medigap fills every gap left by Original Medicare. It doesn’t — Medigap only supplements the cost-sharing on services Original Medicare already covers. Since routine hearing care was never covered by Original Medicare in the first place, there’s nothing for Medigap to supplement. This exclusion applies regardless of which Medigap plan letter you have, from the most basic to the most comprehensive.

How Do Medicare Advantage Plans Cover Hearing Aids?

Medicare Advantage plans are private alternatives to Original Medicare, and many go beyond Original Medicare’s coverage by including hearing benefits. But “includes hearing coverage” can mean very different things depending on the plan — some offer a basic discount program with reduced pricing through a provider network, while others offer meaningful allowances or even full coverage toward premium hearing technology. There’s no standardization here the way there is with Medigap, so you genuinely have to read the specifics rather than assume based on a plan’s general marketing.

What Should I Check Before Choosing a Plan for Hearing Coverage?

Use this as a working checklist when comparing Medicare Advantage plans specifically for hearing benefits:

• Preferred providers. Confirm whether the plan requires in-network hearing specialists for full benefits, and check that your preferred audiologist or hearing aid provider is actually on that list — a plan with a strong-sounding hearing benefit is worth little if your provider isn’t in-network.
• Hearing examinations. Does the plan include routine hearing screenings and diagnostic testing, and what deductibles or copayments apply specifically to hearing benefits, separate from the plan’s general cost-sharing?
• Fittings. Check coverage for the fitting process itself, including how many fitting or adjustment sessions are included — getting hearing aids properly tuned often takes more than one visit.
• Hearing aid devices. How much of the actual device cost is covered? Some plans offer a flat allowance, others a percentage, and others full coverage up to a specific technology tier — these structures produce very different out-of-pocket outcomes depending on the hearing aids you actually want.
• Ongoing costs. Look into coverage for maintenance, repairs, and batteries — costs that continue well after the initial purchase and are easy to overlook when comparing plans.

Bottom Line

Hearing aid coverage isn’t something to assume you have — Original Medicare and Medigap both leave it uncovered entirely, and Medicare Advantage coverage varies too widely to take at face value from a plan’s general marketing. Going through this checklist against a plan’s actual Evidence of Coverage document, rather than its summary brochure, is what actually tells you whether a plan meets your hearing care needs. If you need help sorting through the specifics, reach out to an independent Medicare broker — we’re here to listen.

Key Takeaways

• Original Medicare (Parts A and B) doesn’t cover routine hearing exams, hearing aids, or fittings.
• Medigap doesn’t add hearing coverage either, since it only supplements services Original Medicare already covers.
• Medicare Advantage plans vary enormously in hearing benefit structure — from basic discount programs to comprehensive device coverage.
• Confirming your preferred hearing provider is actually in-network matters as much as the coverage amount itself.
• Fitting sessions, ongoing maintenance, and batteries are easy to overlook when comparing plans but add up over time.
• Always check a plan’s actual Evidence of Coverage document rather than relying on general marketing descriptions of “hearing benefits.”

FAQ – Medicare Advantage Hearing Aid Coverage

Does Original Medicare cover hearing aids?
No. Neither Part A nor Part B covers routine hearing exams, hearing aids, or fittings.

Does Medigap cover hearing aids?
No. Medigap only supplements costs for services Original Medicare already covers, and since hearing aids aren’t covered by Original Medicare, there’s nothing for Medigap to supplement.

Do all Medicare Advantage plans cover hearing aids the same way?
No. Coverage ranges from basic discount programs to full coverage of premium devices, varying significantly by plan and insurer.

What should I check before choosing a Medicare Advantage plan for hearing coverage?
Provider network requirements, whether routine exams are included, fitting session coverage, how much of the device cost is covered, and whether maintenance and batteries are included.

Are hearing aid fittings covered under Medicare Advantage hearing benefits?
Often yes, but the number of included fitting or adjustment sessions varies by plan — worth confirming directly rather than assuming unlimited fittings are included.
