What Does Medicare Cover? Part A, Part B, Nursing Home Costs & Drug Coverage

Key Takeaways

  • Original Medicare includes Part A and Part B, covering hospital care, medical services, preventive care, and many necessary treatments.
  • Understanding what does medicare part a and B cover helps you identify coverage gaps and plan healthcare expenses more effectively.
  • Original Medicare offers broad healthcare protection but does not cover every service, prescription, or long-term care need.

Medicare can feel confusing when you first start exploring your options. Many people hear terms like Part A, Part B, deductibles, and coverage limits but are not always sure what they mean. Understanding what does original medicare cover can help you make informed healthcare decisions and avoid unexpected costs.
Original Medicare includes two main parts: Part A and Part B. Together, they cover many essential healthcare services. However, they do not cover everything. Let’s break down what each part covers and where you may need additional coverage.

Understanding Original Medicare

Before looking at specific benefits, it helps to understand the basics. Original Medicare is the federal health insurance program primarily designed for people age 65 and older. Some younger individuals with qualifying disabilities may also qualify.
When people ask what does medicare cover, they are usually referring to Original Medicare. This program consists of Part A and Part B. Each part covers different healthcare services. Together, they create the foundation of Medicare coverage for millions of Americans.

However, Original Medicare does not include most prescription drug coverage, routine dental care, vision care, or hearing services. Because of this, many beneficiaries choose additional coverage options.

How Much Does Original Medicare Cost?

Understanding what Original Medicare covers is important. However, knowing what it costs matters just as much. Most people do not pay a monthly premium for Part A. This is because they or their spouse paid Medicare taxes for at least 10 years while working.
Even so, Part A is not completely free. It includes a deductible for each benefit period. If you stay in a hospital or skilled nursing facility for a longer time, you may also pay coinsurance.
In 2026, the Part A hospital deductible is $1,736 per benefit period.
Part B works differently. Nearly everyone pays a monthly premium for this coverage.
In 2026, the standard Part B premium is $202.90 per month. Some higher-income beneficiaries may pay more. Part B also has an annual deductible of $283. After meeting the deductible, Medicare usually pays 80% of covered services. You are responsible for the remaining 20%.
Another important thing to know is that Original Medicare does not have an annual out-of-pocket maximum.
As a result, costs can add up quickly if you need frequent medical care. Because of this, many people choose additional coverage to help reduce expenses.

What Does Medicare Part A Cover?

Many people wonder what does medicare part a cover because it focuses on hospital-related services. Part A helps cover care received when you are formally admitted to a healthcare facility.

Generally, medicare part a covers services such as:

  • Inpatient hospital stays
  • Skilled nursing facility care following a qualifying hospital stay
  • Hospice care for eligible patients
  • Certain home health services

Part A helps reduce the financial burden of major medical events. However, coverage rules, deductibles, and eligibility requirements still apply. Therefore, reviewing your specific benefits remains important before receiving care.

Hospital Care and Skilled Nursing Services

Hospital coverage represents one of the most valuable benefits provided by Part A. If you require inpatient treatment, Part A can help pay for your hospital room, meals, nursing services, medications administered during your stay, and other approved services.
Many people also ask, does medicare cover nursing home costs? The answer depends on the type of care needed. Medicare may cover short-term skilled nursing facility care after a qualifying hospital stay. However, Medicare generally does not pay for long-term custodial nursing home care when assistance with daily living activities is the primary need.
Understanding this distinction helps avoid costly misunderstandings later.

What Does Medicare Part B Cover?

While Part A focuses on hospital care, what does medicare part b cover is equally important because most healthcare services occur outside the hospital.
Part B covers medically necessary services and preventive care. It helps beneficiaries access doctors, specialists, outpatient treatment, and screenings that support long-term health.
In simple terms, medicare part b covers many of the healthcare services people use regularly throughout the year. This makes Part B a critical component of Original Medicare coverage.

Common Services Covered by Medicare Part B

Part B covers a wide range of outpatient and preventive services. These benefits help beneficiaries manage both short-term illnesses and ongoing health conditions.

Common Part B services include:

  • Doctor visits and specialist appointments
  • Outpatient hospital services
  • Preventive screenings and wellness visits
  • Laboratory tests and diagnostic services
  • Durable medical equipment
  • Physical and occupational therapy
  • Mental health services
  • Certain vaccines and preventive treatments

Because preventive care plays a major role in maintaining health, Part B encourages early detection and treatment whenever possible.

Prescription Drugs and Medicare Part B

Prescription drug coverage often creates confusion. While most outpatient medications fall under Medicare Part D, certain medications receive coverage through Part B.
Many beneficiaries search for a list of drugs covered by medicare part b. Part B may cover specific medications that are administered in a doctor’s office, certain injectable drugs, some cancer treatments, immunosuppressive drugs in qualifying situations, and select medications used with durable medical equipment.
Coverage rules vary based on medical necessity and treatment settings. Therefore, beneficiaries should always verify whether a medication qualifies under Part B before beginning treatment.

What Original Medicare Does Not Cover

Although Original Medicare provides extensive protection, it does not cover every healthcare expense. Understanding these gaps helps you prepare financially and explore additional coverage options if needed.
Original Medicare generally does not cover routine dental care, eyeglasses, hearing aids, cosmetic procedures, most prescription medications, or long-term custodial nursing home care.

As healthcare needs change, these uncovered services can become significant expenses. Consequently, many beneficiaries consider supplemental coverage to help reduce out-of-pocket costs and expand protection beyond Original Medicare benefits.
Coverage rules can change, and certain services may have specific eligibility requirements. For the most current information about Original Medicare benefits and exclusions, review the official Medicare coverage guide here.

What Does Medicare Part D Cover?

Original Medicare does not cover most prescription drugs you pick up at a pharmacy. That’s where Medicare Part D helps. It provides coverage for many prescription medications. Private insurance companies approved by Medicare offer Part D plans. Each plan has its own list of covered drugs, called a formulary.
Costs vary by plan. Premiums, deductibles, and copayments may differ, so it is important to compare your options. Timing also matters. If you delay enrollment and do not have other creditable drug coverage, you may face a late enrollment penalty. It is also important to understand the difference between Part B and Part D.
Part B may cover medications given in a doctor’s office or clinic. Part D covers most medications you take on your own at home.

Medicare Supplement (Medigap) Plans: Covering the Gaps

Original Medicare leaves beneficiaries responsible for certain out-of-pocket costs.

To help with these expenses, many people choose a Medicare Supplement plan, also known as Medigap. Medigap plans are sold by private insurance companies. They work alongside Original Medicare and help cover costs that Medicare does not fully pay.

Depending on the plan, Medigap may help with:

  • Part A hospital coinsurance
  • Part B coinsurance or copayments
  • Part A deductibles
  • Skilled nursing facility coinsurance
  • Foreign travel emergency coverage on certain plans

In most states, Medigap plans are standardized. This means the benefits remain the same regardless of the insurance company. However, premiums and customer service can vary. That is why comparing providers is often worthwhile.

Keep in mind that Medigap cannot be used with a Medicare Advantage plan.

Medicare Advantage (Part C): An Alternative to Original Medicare

Many people researching Original Medicare also explore Medicare Advantage plans. These plans are offered by private insurance companies that contract with Medicare. By law, Medicare Advantage plans must cover everything Original Medicare covers.
In addition, many plans include extra benefits. These may include dental, vision, hearing, and prescription drug coverage. One of the biggest advantages is the annual out-of-pocket maximum. This feature helps limit how much you spend on covered healthcare services each year.
However, Medicare Advantage plans often use provider networks. This may limit your choice of doctors, specialists, and hospitals.
Choosing between Original Medicare with Medigap and Part D or a Medicare Advantage plan depends on your needs. Your budget, healthcare usage, and provider preferences can all influence the right choice.

When Can You Enroll in Original Medicare?

Knowing when to enroll is just as important as understanding your coverage. Most people become eligible for Medicare when they turn 65. The Initial Enrollment Period lasts seven months. It starts three months before your birthday month, includes your birthday month, and continues for three months after.
Enrolling during this window helps you avoid delays and potential penalties. If you miss this period and do not qualify for a Special Enrollment Period, you may need to wait for the General Enrollment Period. The General Enrollment Period runs from January 1 through March 31 each year. You should also be aware of the Annual Enrollment Period.
This period runs from October 15 through December 7 each year. During this time, you can review and make changes to your Medicare Advantage or Part D coverage. Reviewing your coverage every year can help ensure it still fits your healthcare needs and budget.
