What Medicare Does and Does Not Cover: A Plain Language Guide
One of the most common questions families ask when a parent turns 65 or begins needing more care is a simple one: Does Medicare cover this? The answer is almost never a simple yes or no. Medicare covers a wide range of medical services, but it has significant gaps that catch many families by surprise, sometimes at the worst possible moment.
The biggest misconception Linda Clement regularly hears in her work as a Certified Senior Advisor (CSA)® and Certified Placement and Referral Specialist (CPRS), and as the founder of Peace of Mind Senior Solutions LLC in North Richland Hills, Texas, is that Medicare will cover long-term care costs. It will not. Understanding what Medicare covers and what it does not is one of the most important financial planning steps a family can take before a health crisis arrives.
This guide breaks down Medicare in plain language, explains what each part covers, identifies the most significant gaps, and explains the options available to fill them.
The Four Parts of Medicare: A Quick Overview
Medicare is divided into four parts, each covering different types of care. Understanding how they fit together is the foundation for understanding what is and is not covered.
Part A – Hospital Insurance: Part A covers inpatient hospital stays, skilled nursing facility care following a qualifying hospital stay, hospice care, and some home health services. Most people pay no monthly premium for Part A if they or their spouse worked and paid Medicare taxes for at least 40 quarters. Part A is not free, however. In 2026, the inpatient hospital deductible is $1,736 per benefit period, and daily coinsurance of $434 applies for days 61 through 90 of a hospital stay.
Part B – Medical Insurance: Part B covers physician services, outpatient care, preventive services, durable medical equipment such as walkers and wheelchairs, and some home health services. Part B requires a monthly premium. In 2026, the standard Part B premium is $202.90 per month, and the annual deductible is $283. After the deductible, Medicare pays 80 percent of approved costs, and the beneficiary pays the remaining 20 percent with no out-of-pocket cap on that 20 percent under Original Medicare.
Part C – Medicare Advantage: Medicare Advantage plans are offered by private insurance companies and cover everything Parts A and B cover, often with additional benefits such as dental, vision, hearing, and drug coverage. These plans have an annual out-of-pocket maximum, which Original Medicare does not. The tradeoff is that Advantage plans use provider networks and often require prior authorizations for services.
Part D – Prescription Drug Coverage: Part D covers outpatient prescription drugs. It is offered through private insurance plans and requires a separate monthly premium. In 2026, the Part D out-of-pocket cap for covered drugs is $2,100 per year. Insulin is capped at $35 per month for Medicare beneficiaries. Drugs not on a plan’s formulary may not be covered at all.
What Medicare Part A Covers
Part A is most people’s primary protection against the cost of serious illness or injury requiring hospitalization. Here is what it covers and its limits.
Inpatient Hospital Stays
Part A covers inpatient hospital care, including room and board, nursing care, meals, and most tests and treatments during the stay. In 2026, the deductible is $1,736 per benefit period. Days 1 through 60 of a hospital stay have no daily coinsurance beyond the deductible. Days 61 through 90 incur $434 in coinsurance per day. Beyond 90 days, lifetime reserve days are available at $868 per day. A benefit period resets 60 days after discharge.
Skilled Nursing Facility Care
Medicare covers up to 100 days in a skilled nursing facility following a qualifying hospital stay of at least three consecutive inpatient days. Days 1 through 20 are covered fully. Days 21 through 100 require a daily coinsurance of $217 in 2026. After 100 days, Medicare pays nothing.
This is one of the most important and most misunderstood limits in Medicare. Coverage in a skilled nursing facility is for recovery and rehabilitation, not for ongoing custodial care. Once a resident no longer makes measurable progress toward recovery goals, Medicare coverage ends, regardless of whether the person still needs daily care.
The Observation Status Trap
This is one of the most financially dangerous situations families encounter. If a hospital places a patient under observation status rather than formally admitting them as an inpatient, Part A does not apply in the same way. More critically, days spent under observation status do not count toward the three-day inpatient stay required to qualify for skilled nursing facility coverage. A patient can spend four days in a hospital bed and still receive a large bill for rehabilitation because those days were classified as outpatient observation rather than inpatient care. Families should ask directly every day of a hospital stay whether the patient is admitted as an inpatient or is under observation status.
Hospice Care
Part A covers hospice care for beneficiaries certified as terminally ill with a prognosis of six months or less. Hospice focuses on comfort and quality of life rather than curative treatment. Room and board are not covered by Medicare under hospice, though the medical services, medications related to the terminal diagnosis, and support services are.
Home Health Care
Medicare covers medically necessary home health care when a physician certifies the need, and the patient is homebound. Covered services include skilled nursing visits, physical therapy, occupational therapy, and speech-language therapy. Non-medical personal care assistance, such as help with bathing or cooking, is not covered unless it accompanies skilled care.
What Medicare Part B Covers
Part B covers the outpatient side of medical care. Here are the most important categories.
Physician Services and Outpatient Care
Part B covers visits to doctors, specialists, and outpatient clinics. After the $283 annual deductible in 2026, Medicare pays 80 percent of the approved amount, and the beneficiary pays 20 percent. There is no out-of-pocket maximum for 20 percent coinsurance under Original Medicare, meaning a serious illness can result in substantial cost-sharing even with Medicare coverage.
Preventive Services
Many preventive services are covered at 100 percent under Part B with no deductible or copay. These include annual wellness visits, flu and pneumonia vaccines, mammograms, colonoscopies, bone density tests, diabetes screenings, and cardiovascular screenings. This is one of Medicare’s strongest features, and beneficiaries should take full advantage of it.
Durable Medical Equipment
Part B covers medically necessary durable medical equipment, including walkers, wheelchairs, hospital beds for home use, oxygen equipment, and CPAP machines. Equipment must be prescribed by a physician and obtained from a Medicare-approved supplier.
Mental Health Services
Part B covers outpatient mental health services, including visits to psychiatrists, psychologists, and clinical social workers. Inpatient psychiatric facility care is covered under Part A, with different limits than those for general hospital care.
What Medicare Does Not Cover: The Major Gaps
This is where families are most frequently surprised. These are the services and costs that Medicare does not cover and that require separate planning.
Long-Term Custodial Care
This is the most significant gap in Medicare for families navigating senior living decisions. Medicare does not pay for custodial care, which means ongoing help with activities of daily living such as bathing, dressing, eating, toileting, and mobility. This applies whether that care is provided at home, in an assisted living community, or in a nursing home.
Medicare covers skilled care and recovery. It does not cover the kind of ongoing personal care that most seniors in assisted living or memory care need. Families who expect Medicare to cover assisted living costs will find it does not. Assisted living in the Dallas-Fort Worth area typically costs $3,500 to $6,000 per month, and that cost is paid primarily by the family through private pay, long-term care insurance, VA benefits, or, eventually, Medicaid.
Dental Care
Original Medicare does not cover routine dental care, including checkups, cleanings, X-rays, fillings, root canals, tooth extractions, or dentures. Some Medicare Advantage plans offer limited dental benefits with annual caps, but the coverage is typically not comprehensive. Seniors who delay dental care due to cost risk more serious health complications, as oral health is closely connected to cardiovascular and overall health.
Vision Care
Original Medicare does not cover routine eye exams, eyeglasses, or contact lenses. It covers medically necessary eye care, such as treatment for glaucoma, macular degeneration, or cataracts, and one pair of eyeglasses after cataract surgery. For routine vision care, seniors must pay out of pocket or obtain coverage through a Medicare Advantage plan with vision benefits.
Hearing Aids
Original Medicare does not cover hearing aids or routine hearing exams. Prescription-grade hearing aids can cost $4,000 to $6,000 or more out of pocket. Over-the-counter hearing aids have become available in recent years at lower price points, but they are not appropriate for all types or severities of hearing loss. Some Medicare Advantage plans offer partial hearing aid coverage, though benefits vary significantly.
Prescription Drugs Under Original Medicare
Original Medicare Parts A and B do not cover most outpatient prescription drugs. A separate Part D prescription drug plan is required. Seniors who do not enroll in Part D when first eligible and do not have other creditable coverage will face a late enrollment penalty of 1 percent of the national base beneficiary premium for each month of delay, which is permanent.
Care Outside the United States
Original Medicare generally does not cover medical care received outside the United States. Some Medigap supplement plans offer limited emergency coverage abroad, but it is not universal. Seniors who travel internationally should consider travel health insurance.
Most Foot Care
Medicare does not cover routine foot care, such as trimming toenails or treating corns and calluses. It does cover foot care when medically necessary, such as for diabetic foot complications or when a systemic condition affects the feet.
Acupuncture and Most Alternative Care
Medicare covers acupuncture only for chronic low back pain. Most other alternative and complementary care, including chiropractic services beyond specific spinal adjustments, naturopathic care, and massage therapy, is not covered.
The 20 Percent Problem
Even for services Medicare does cover, the cost-sharing can add up significantly. Part B pays 80 percent of approved costs after the deductible. The remaining 20 percent is the beneficiary’s responsibility with no cap. A major surgery, a serious illness, or multiple specialist visits in a single year can result in thousands of dollars in 20 percent coinsurance charges under Original Medicare.
This is why Medigap supplement plans exist. A Medigap plan fills in the gaps in Original Medicare, covering deductibles, coinsurance, and copays. In 2026, Plan G is the most popular Medigap option for new Medicare enrollees. Monthly Medigap plan premiums vary by age, health status, and insurer, typically ranging from $150 to $480 or more. The trade-off is predictable costs and the freedom to see any Medicare-accepting provider nationwide, with no network restrictions.
Medicare Advantage plans address out-of-pocket costs differently by capping in-network out-of-pocket costs at $9,350 in 2026. The tradeoff is between provider networks and prior authorization requirements.
How Medicare Interacts with Assisted Living and Senior Care Decisions
For families in the Dallas-Fort Worth area evaluating senior living options, understanding what Medicare will and will not pay for is essential to building a realistic financial plan. Here is how it plays out in practice.
If a parent is hospitalized and then needs short-term rehabilitation in a skilled nursing facility, Medicare Part A may cover up to 100 days of that stay, though full coverage applies only to the first 20 days, and the stay must follow a qualifying three-day inpatient hospital admission. This is not the same as paying for ongoing assisted living.
Once a senior transitions from short-term rehabilitation to needing ongoing help with daily activities, Medicare coverage ends. From that point forward, the family is in private pay territory unless VA benefits, long-term care insurance, or Medicaid apply.
Medicare does not pay for assisted living, memory care, or the custodial care portion of nursing home stays. Families who plan as though it will often arrive at a crisis point without adequate resources in place.

Frequently Asked Questions
Does Medicare cover assisted living?
No. Medicare does not cover the cost of assisted living, memory care, or ongoing custodial care in any setting. Medicare covers medically necessary skilled care and short-term rehabilitation, but not the personal care assistance that assisted living provides on an ongoing basis. Families typically pay for assisted living through private savings, long-term care insurance, VA benefits, or eventually Medicaid.
How many days does Medicare cover in a skilled nursing facility?
Medicare Part A covers up to 100 days in a skilled nursing facility following a qualifying hospital stay of at least three consecutive inpatient days. Days 1 through 20 are covered fully. Days 21 through 100 require a daily coinsurance of $217 in 2026. After 100 days, Medicare pays nothing. Coverage also ends earlier if a resident is no longer making measurable progress toward recovery goals.
What is the observation status trap and why does it matter?
Observation status means a patient is classified as an outpatient even while in a hospital bed. Days under observation status do not count toward the three-day inpatient stay required to qualify for Medicare-covered skilled nursing facility care. A patient who spends four days in the hospital but is classified as observation the entire time would receive no Medicare coverage for subsequent rehabilitation. Families should ask every day whether a patient is admitted as an inpatient or is under observation.
Does Medicare cover dental, vision, and hearing?
Original Medicare does not cover routine dental care, routine eye exams and glasses, or hearing aids. Some Medicare Advantage plans offer limited benefits in these areas, but coverage varies significantly between plans and often includes annual caps. Seniors who rely on Original Medicare alone will pay these costs out of pocket.
What is the difference between Original Medicare and Medicare Advantage?
Original Medicare consists of Parts A and B administered by the federal government. It covers a wide range of services but has no out-of-pocket maximum, meaning cost sharing can be unlimited in a serious illness year. Medicare Advantage plans are offered by private insurers, cover everything Parts A and B cover, usually include drug coverage and extra benefits, and have an annual out-of-pocket maximum. The tradeoff is provider networks and prior authorizations that do not exist under Original Medicare.
What is a Medigap plan and do I need one?
A Medigap plan, also called a Medicare Supplement plan, is private insurance that pays the deductibles, coinsurance, and copays that Original Medicare leaves to the beneficiary. Plan G is the most comprehensive and most popular option for new Medicare enrollees in 2026. Whether a Medigap plan makes sense depends on a person’s health, finances, and how much exposure to the 20 percent coinsurance under Part B they want to carry. A licensed Medicare insurance broker can compare plans and costs at no charge.
