What Is Not Covered by Medicare Part A
Part A covers hospital stays, but most of the care you actually use happens outside a hospital, and that's where Part A stops paying.
Part A covers hospital care, not the rest of your health care
Part A pays for inpatient hospital stays, skilled nursing care after a hospital stay, hospice, and some home health care. It does not cover doctor visits, outpatient care, prescription drugs you take at home, dental care, vision care, hearing aids, or long-term custodial care like help with bathing and dressing.
This surprises a lot of people because they assume Medicare means everything is covered once they turn 65. Part A is only one piece. Part B covers doctor visits and outpatient services, Part D covers prescription drugs, and neither of those is automatic. You have to enroll in them separately, and each one costs its own premium.
Whether you also have Part B changes what's missing
If you have Part A only, the gap is enormous. Routine doctor visits, lab work, outpatient surgery, and preventive screenings all fall under Part B, and without it you'd be paying for all of that yourself.
Most people enroll in both Part A and Part B around the same time, often automatically if they're already collecting Social Security. If you delayed Part B because you had coverage through an employer, check whether that coverage is still enough before you assume Medicare has you covered.
Even with both Part A and Part B, dental, vision, hearing, and long-term custodial care stay uncovered. That's a separate gap that neither part fills, and it's where many people look at a Medicare Advantage plan or a standalone dental or vision policy instead.
What people miss: custodial care isn't the same as skilled care
Part A will pay for skilled nursing care, but only for a limited recovery period after a hospital stay, and only for care that requires a nurse or therapist. It stops once the care becomes custodial, meaning help with daily activities like eating, dressing, or using the bathroom.
This is the gap that catches families off guard. A parent moves into a nursing home for long-term help with daily living, and the family assumes Medicare is paying for it. It isn't, unless there's a skilled medical need tied to a recent hospital stay. Long-term custodial care is paid out of pocket, through long-term care insurance, or eventually through Medicaid for those who qualify.
If you're planning for a parent's care or your own, it's worth asking a Medicare counselor or the facility directly whether a stay would be classified as skilled or custodial, because that distinction decides who pays.
Questions people ask about this
Does Medicare Part A cover prescription drugs?
No, Part A does not cover prescription drugs you take at home. That's the job of Part D, a separate drug plan you enroll in and pay a premium for. Part A only covers drugs given to you during an inpatient hospital stay.
Does Medicare Part A cover dental implants or dentures?
No, Part A does not cover routine dental care, implants, or dentures. Dental coverage generally has to come from a separate dental plan or a Medicare Advantage plan that includes dental benefits, since original Medicare excludes it.
Will Medicare Part A pay for a nursing home stay?
Only in limited circumstances. Part A covers skilled nursing care for a set recovery period following a hospital stay, but it does not cover long-term custodial care, which is the kind of help most people need in a nursing home over time.
Does Part A cover home health aides for daily living help?
Part A covers some home health care, but only skilled services like nursing care or physical therapy ordered by a doctor. It does not cover a home health aide hired just to help with bathing, dressing, or meal preparation on an ongoing basis.
Do I need Medicare Part B if I already have Part A?
Most people need both, since Part A alone leaves out doctor visits, outpatient care, and preventive screenings. Whether you need to enroll in Part B right away depends on whether you have other qualifying coverage, so check with Social Security or your employer's benefits office before deciding.

Pull out your Medicare card and check whether you're enrolled in Part A only or in both Part A and Part B. If it's Part A only, call Social Security or your State Health Insurance Assistance Program this week to ask what you're missing and what it would cost to add Part B now versus later. If you or a parent are weighing a nursing home stay, ask the facility directly whether the care qualifies as skilled or custodial, since that answer decides whether Medicare pays anything toward it. While you're at it, make a list of the specific gaps that matter most to you, dental, vision, hearing, or long-term care, so you know what to ask about when you compare supplemental or Medicare Advantage options.
