Whether you're new to Original Medicare or have been enrolled for some time, understanding the limitations of your coverage is important as you navigate decisions about your healthcare. One of the main reasons why Original Medicare doesn't cover 100% of your medical bills is because it operates on a cost-sharing model.
Medicare never covers the full cost of a skilled nursing facility. Medicare does not always provide 100 days of rehabilitation, it will pay “up to” 100 days. Medicare Part A covers the full cost of the first 20 days in a rehabilitation facility when a patient meets certain qualifications after a hospital stay.
Days 1–60: (of each benefit period): $0 after you meet your Part A deductible ($1,632) ($1,676 in 2025). Days 61–90: (of each benefit period): $408 ($419 in 2025) each day. In Original Medicare, these are additional days that Medicare will pay for when you're in a hospital for more than 90 days.
Once you meet your deductible, Part A will pay for days 1–60 that you are in the hospital. For days 61–90, you will pay a coinsurance for each day. If you need to stay in the hospital for longer than 90 days, you can use up to 60 lifetime reserve days.
Medicare will stop paying for your inpatient-related hospital costs (such as room and board) if you run out of days during your benefit period. To be eligible for a new benefit period, and additional days of inpatient coverage, you must remain out of the hospital or SNF for 60 days in a row.
You pay nothing for covered services the first 20 days that you're in a skilled nursing facility (SNF). You pay a daily coinsurance for days 21-100, and you pay all costs beyond 100 days. Visit Medicare.gov, or call 1-800-MEDICARE (1-800-633-4227) to get current amounts.
Medicare does not cover 100% of all costs. CDI recommends purchasing a Medicare Supplement Insurance policy if you have traditional Medicare to help offset your health care costs. If you have questions related to Medicare, contact Medicare or your local Department of Aging (HICAP).
Medicare covers inpatient rehab in a skilled nursing facility after a qualifying hospital stay that meets the 3-day rule. The 3-day rule for Medicare requires that you are admitted to the hospital as an inpatient for at least 3 days for rehab in a skilled nursing facility to be covered.
When a doctor deems it medically necessary, Medicare will cover hospital beds to use at home. Generally, Part B will cover 80% of the cost. Medigap and Medicare Advantage may pay more. There are times when a doctor may feel it is medically necessary for a person to use a hospital bed at home.
Can Medicare take your home to cover nursing home expenses? Medicare can't take your home and doesn't cover nursing home room and board. However, a Medicaid lien can be placed on your home, and they can sell it once you pass to recover the funds.
How much does Medicare pay for doctor visits? Anyone who has had Medicare Part B for longer than 12 months is entitled to a free annual wellness visit that is not subject to a deductible. Beyond that, Medicare Part B covers 80% of the Medicare-approved cost of medically necessary doctor visits.
We don't cover these routine items and services: Routine or annual physical checkups (visit Medicare Wellness Visits to learn about exceptions). exams required by third parties, like insurance companies, businesses, or government agencies. Eye exams for prescribing, fitting, or changing eyeglasses.
AARP/UnitedHealthcare is the best company for Medigap plans in 2025. For most people, the best company for Medigap coverage is AARP/UnitedHealthcare. Medicare Supplement (Medigap) plans cover many of the costs that you usually pay if you have regular Medicare.
After you pay the Part A deductible, Medicare pays the full cost of covered hospital services for the first 60 days of each benefit period when you're an inpatient, which means you're admitted to the hospital and not for observational care. Part A also pays a portion of the costs for longer hospital stays.
Medicare Part A (hospital insurance)
You're eligible for Part A at no cost at age 65 if 1 of the following applies: • You receive or are eligible to receive benefits from Social Security or the Railroad Retirement Board (RRB).
It lasts for 7 months, starting 3 months before you turn 65, and ending 3 months after the month you turn 65. My birthday is on the first of the month. If you miss your 7-month Initial Enrollment Period, you may have to wait to sign up and pay a monthly late enrollment penalty for as long as you have Part B coverage.
Original Medicare covers up to 90 days of inpatient hospital care each benefit period. You also have an additional 60 days of coverage, called lifetime reserve days.
Medicare pays for medical and surgical services provided by PAs at 85 percent of the physician fee schedule. This rate applies to all practice settings, including hospitals (inpatient, outpatient and emergency departments), nursing facilities, homes, offices and clinics. It also applies to first assisting at surgery.
How Medicare Part B cost sharing works. You will pay the Medicare Part B premium and share part of costs with Medicare for covered Part B health care services. Medicare Part B pays 80% of the cost for most outpatient care and services, and you pay 20%.
But there are trade-offs. Medicare Advantage plans often have a limited network of hospitals and physicians. And while the premiums are typically low, enrollees could end up paying more in the long run in copays and deductibles if they develop a serious illness.
Medicare Part B covers emergency ambulance services and, in limited cases, non-emergency ambulance services. Medicare considers an emergency to be any situation when your health is in serious danger and you cannot be transported safely by other means.
