Understanding How Medicare Works for Seniors
Medicare 101: What Is It?
We are privately owned and not affiliated with the government in any way or form.
Medicare is a government-run health insurance program designed mainly for seniors and certain individuals with disabilities. It helps cover the cost of medical care using a combination of personal payments and funds collected through payroll taxes. The program is overseen by the Centers for Medicare & Medicaid Services (CMS).
Who Can Get Medicare?
Medicare is generally available to the following groups of people:
- Adults age 65 and older
- People of any age with End-Stage Renal Disease (ESRD)
- Some younger individuals with qualifying disabilities
Your benefits under Medicare will vary depending on which parts of the program you’re enrolled in. For a breakdown of each part and what it covers, see the section titled “Medicare Parts A, B, C and D.”
Medicare and Seniors
The majority of Medicare beneficiaries are seniors aged 65 and up. Medicare is divided into four main parts, each offering specific types of coverage:
- Part A: Hospital care
- Part B: Medical services and outpatient care
- Part C: Medicare Advantage (bundled private plans that may include additional benefits)
- Part D: Prescription drug coverage
In addition, there are Medigap plans, which are optional supplemental policies that help pay for costs not fully covered by Medicare. While Medigap isn’t part of Medicare itself, it can be added to Original Medicare to help reduce out-of-pocket expenses.

How Do Seniors Usually Qualify for Medicare?
If you’re 65 or older, you’re likely able to enroll in all parts of Medicare. Depending on your work history and other factors, you may even qualify for certain benefits at no cost.
Qualifying for Part A
Seniors age 65 and up can sign up for Medicare Part A, which covers hospital care. Most people – but not everyone – can get it for free. If you qualify for premium-free Part A, you won’t need to pay a monthly fee for this coverage.
You may receive premium-free Part A if any of the following apply:
- You’re already getting retirement benefits from Social Security or the Railroad Retirement Board
- You’re eligible for those benefits but haven’t started collecting them yet
- You or your spouse worked in a Medicare-covered job and paid Medicare taxes for at least 40 quarters (about 10 years total)
- You’re currently married and your spouse qualifies for free Medicare Part A
- You’re divorced after being married for at least 10 years, and your ex-spouse qualifies
- You’re widowed and were married for at least 9 months before your spouse passed, and they qualified for premium-free benefits
If you don’t qualify for free Part A, you’ll need to pay a monthly premium. In 2025, the costs are:
- $518 per month if you have fewer than 30 quarters of work history
- $285 per month if you have between 30 and 39 quarters
Learn more in the Medicare Part A section.
Who Qualifies for Medicare Part B?
Most seniors who get free Part A are also eligible for Medicare Part B (medical coverage) automatically when they turn 65. They’ll typically be enrolled without needing to apply, but can opt out if they choose. Be aware: delaying enrollment can lead to late penalties unless you qualify for a Special Enrollment Period.
Important: Seniors in Puerto Rico must manually apply for Part B, even if they have Part A. They can do this using the Medicare Part B enrollment form (CMS-40B).
If you need to pay for Medicare Part A, you must meet all of the following to get Part B:
- Be 65 or older
- Be a U.S. citizen or a lawful permanent resident who has lived in the U.S. for at least five continuous years
- Live in the U.S. at the time you apply
Visit the Medicare Part B section for more details.
Who Can Enroll in Medicare Part C (Medicare Advantage)?
To join a Medicare Advantage (Part C) plan, you must:
- Already have Medicare Parts A and B
- Be a U.S. citizen, national, or lawfully present resident
- Live within the plan’s service area
See the Medicare Part C section for more information.
Who Can Get Medicare Part D (Drug Coverage)?
You can sign up for a Medicare Part D plan if:
- You have Medicare Part A and/or Part B
- You don’t already have creditable drug coverage through another plan
If you’re enrolled in a Medicare Advantage (Part C) plan, your drug coverage may already be included—so double-check your plan before signing up for Part D separately.
More details are available in the Medicare Part D section.
Who’s Eligible for a Medigap Plan?
Medigap plans help cover the costs that Medicare Parts A and B don’t pay for. To be eligible, you must:
- Be enrolled in both Medicare Part A and Part B
- Not be enrolled in a Medicare Advantage (Part C) plan
- Be willing to pay a monthly premium to a private insurance company
- Purchase the plan from a provider licensed in your state
You can search for Medigap policies available in your area by ZIP code using this tool: https://www.medicare.gov/medigap-supplemental-insurance-plans/#/m?lang=en&year=2025

Medicare Parts A, B, C, and D Explained
Medicare is divided into four main parts—Parts A, B, C, and D—each covering different types of health care services. Understanding what each part offers can help you make informed choices about your health coverage. Below, you’ll find a breakdown of each Medicare part, including what it covers, how costs work, and what seniors can expect.
Medicare Part A: Hospital and Related Care
Medicare Part A is the portion of Medicare that helps cover hospital stays and related services. It’s automatically included for most people who qualify for Medicare, and it covers a wide range of inpatient and facility-based care.
What Does Part A Cover?
- Inpatient hospital care, including stays in semi-private rooms, meals, general nursing services, medications, and other hospital supplies
- Care in a skilled nursing facility (SNF), including physical therapy, occupational therapy, speech therapy, and nursing care
- Inpatient mental health care in hospitals and psychiatric facilities
- Hospice care for terminal illnesses
- Home health care services such as skilled nursing visits and therapy
- Ambulance transportation when medically necessary
- Dietary counseling and swing bed services (care in a hospital bed when acute hospital care isn’t needed but skilled care still is)
Costs and How They Work
While Medicare Part A often doesn’t require monthly premiums for most enrollees, there are other costs to be aware of:
- Deductibles: The amount you pay out of pocket before Medicare starts paying. For Part A, this deductible applies each time you have a hospital stay.
- Copayments and Coinsurance: After you meet the deductible, you may pay daily coinsurance fees depending on the length of your hospital or facility stay.
Inpatient Hospital Care Details
When you are admitted to a hospital as an inpatient, Medicare Part A covers up to 90 days of care during each “benefit period.” A benefit period begins on the day you’re admitted to the hospital and ends when you haven’t been in a hospital for 60 consecutive days.
- For days 1 through 60 of your hospital stay, you pay no coinsurance.
- For days 61 through 90, you pay a daily coinsurance fee.
- If your stay goes beyond 90 days, you have access to 60 “lifetime reserve days” at a higher coinsurance cost. You get only 60 lifetime reserve days in total, so use them wisely.
- After your lifetime reserve days are used up, you’re responsible for all costs.
Inpatient Mental Health Care
Part A also covers inpatient mental health treatment at hospitals and psychiatric facilities. Services include room and board, nursing care, medications, and therapy to address conditions such as depression and anxiety.
- There is no limit on days for inpatient mental health care in general hospitals.
- However, psychiatric facilities have a lifetime limit of 190 days.
- Costs follow a similar pattern to hospital stays, with deductibles and coinsurance based on length of stay.
Skilled Nursing Facility (SNF) Care
If you require skilled nursing care or rehabilitation after a hospital stay, Medicare Part A can cover care in a Medicare-certified SNF, but only if:
- You had a qualifying hospital stay of at least three days (not counting the day of discharge).
- You enter the SNF within 30 days after leaving the hospital.
- Your doctor certifies that skilled nursing care is needed for a condition related to your hospital stay.
Costs for SNF care include:
- Days 1–20: Covered 100% by Medicare (no cost to you)
- Days 21–100: You pay a daily coinsurance fee
- Days 101 and beyond: You pay all costs
Hospice Care
Hospice care through Medicare Part A is for individuals with terminal illnesses, focusing on comfort and quality of life rather than curative treatment.
- Hospice care itself has no premium or deductible under Part A.
- You may have small copayments for prescriptions and respite care (short-term care to give your regular caregiver a break).
- Medicare doesn’t cover room and board if hospice care is provided at home or in a long-term care facility—you’re responsible for those costs unless you are admitted for short-term inpatient care for symptom management.
Home Health Care
Medicare Part A also covers certain home health services for beneficiaries who are homebound and require skilled care. This care is intermittent (not around the clock) and includes:
- Skilled nursing visits
- Physical, occupational, and speech therapy
- Home health aide services for personal care like bathing and dressing
- Medical social services
- Injectable drugs for osteoporosis
Medicare will not cover:
- 24/7 care at home
- Meals delivered to your home
- Homemaker services (such as cleaning or cooking) when that is the only type of care you need
- Personal care if that’s the only care you need
If you need durable medical equipment (DME) like walkers, wheelchairs, or hospital beds, Medicare may cover most of the cost, but you usually pay 20% coinsurance for DME.
Medicare Part B
Medicare Part B is designed to cover medically necessary services and preventive care, as well as outpatient treatments that don’t require hospital admission. Unlike Part A, which mainly focuses on hospital stays, Part B supports ongoing healthcare needs outside of inpatient care. This coverage requires enrollees to pay monthly premiums, along with other potential costs depending on their usage.
What Does Medicare Part B Cover?
Medicare Part B includes a wide range of healthcare services and supplies essential for diagnosis, treatment, and maintaining health outside of a hospital stay. Some key categories of Part B coverage include:
- Clinical Research: Medicare supports participation in approved research studies aimed at developing new treatments and medical advancements.
- Diagnostic Tests: This includes lab work, X-rays, MRIs, and other procedures used to diagnose health conditions.
- Surgical Treatment: Medically necessary outpatient surgeries are covered under Part B.
- Medicine: Certain medications, especially those administered by a healthcare professional rather than self-administered drugs, are covered.
- New Types of Patient Care: Medicare often covers innovative care methods as they become medically accepted.
- Ambulance Services: Ground and emergency air ambulance transport for urgent medical needs.
- Durable Medical Equipment (DME): Medical devices prescribed for home use to support mobility or health maintenance.
- Mental Health Care: Both outpatient treatment and limited inpatient services related to mental health.
- Preventive Care: Annual wellness visits and screenings, including one depression screening per year.
Durable Medical Equipment (DME) Included Under Part B
Durable Medical Equipment refers to medically necessary devices prescribed by a doctor for home use. Examples include:
- Blood sugar monitors and test strips
- Canes and crutches
- Commode chairs
- CPAP (Continuous Positive Airway Pressure) devices
- Hospital beds
- Infusion pumps and supplies
- Nebulizers and related medications
- Oxygen equipment and accessories
- Walkers, wheelchairs, and scooters
- Patient lifts and pressure-reducing surfaces
Medicare only pays for DME if both the prescribing doctor and the equipment supplier participate in Medicare. This ensures that the enrollee pays only the deductible and coinsurance rather than the full cost.
Mental Health Care Under Part B
Part B covers outpatient mental health services, which are services provided outside of hospitals without an overnight stay. These include:
- Annual depression screening
- Individual and group psychotherapy (talk therapy)
- Family counseling
- Psychiatric evaluations and diagnostic testing
- Medication management for certain injectable or non-self-administered drugs
- Partial hospitalization programs (more intensive outpatient care)
- Treatment for substance abuse and alcoholism
Costs and Coverage Details for Medicare Part B
Monthly Premiums
All Medicare recipients pay a monthly premium for Part B coverage. In 2025, the standard premium is $185 per month. This amount may be higher for individuals or couples with higher incomes, based on their modified adjusted gross income (MAGI) from tax returns filed two years before applying for Medicare.
If your yearly income in 2023 (for what you pay in 2025) was | You pay each month (in 2025) | ||
File individual tax return | File joint tax return | File married & separate tax return | |
$106,000 or less | $212,000 or less | $106,000 or less | $185.00 |
above $106,000 up to $133,000 | above $212,000 up to $266,000 | Not applicable | $259.00 |
above $133,000 up to $167,000 | above $266,000 up to $334,000 | Not applicable | $370.00 |
above $167,000 up to $200,000 | above $334,000 up to $400,000 | Not applicable | $480.90 |
above $200,000 and less than $500,000 | above $400,000 and less than $750,000 | above $106,000 and less than $394,000 | $591.90 |
$500,000 or above | $750,000 or above | $394,000 or above | $628.90 |
Deductibles and Coinsurance
- Annual Deductible: $257 (2025)
Enrollees pay this amount out of pocket before Medicare begins to cover costs for Part B services each year. - Coinsurance: 20% of Medicare-approved costs after the deductible is met. This means Medicare pays 80%, and the enrollee pays 20% for most covered services.
Common services subject to coinsurance include:
- Doctor visits
- Outpatient therapy
- Durable medical equipment
Ambulance Services Coverage
Medicare Part B covers ambulance transportation to the nearest appropriate facility when other transportation would endanger your health. This includes:
- Ground ambulance
- Emergency air transport (helicopter or airplane) when ground transport is unavailable or too slow
Costs include:
- 20% coinsurance of the Medicare-approved amount
- Deductible applies if not already met
Limited Outpatient Prescription Drugs
Part B covers certain outpatient drugs typically administered in a doctor’s office or hospital outpatient setting, such as injections and infusions. Patients pay:
- 20% coinsurance on Medicare-approved amounts
- Deductible applies before coverage begins
If the hospital participates in the 340B Drug Pricing Program, patients may pay less. Drugs not covered by Part B require separate prescription drug coverage, often through Medicare Part D.
Medicare Part C
Medicare Part C, commonly known as Medicare Advantage, offers an alternative way to receive your Medicare benefits through private insurance companies approved by Medicare. These plans combine all the benefits of Medicare Parts A and B, and often include Part D prescription drug coverage as well.
Many Medicare Advantage plans provide expanded coverage beyond original Medicare, often including vision, hearing, and dental services—benefits not typically covered by standard Medicare.
How Medicare Part C Works
Medicare Part C plans operate similarly to private health insurance plans. Enrollees usually need to use a network of doctors and hospitals designated by the plan to get the full range of benefits at lower costs. Staying inside the network typically means lower copayments compared to standard Medicare. However, care received outside the network can be more expensive or not covered at all, depending on the plan type.
Types of Medicare Part C Plans
There are several kinds of Medicare Advantage plans, each with different rules and coverage options:
- Health Maintenance Organization (HMO) Plans:
These plans require you to get care within the plan’s network, except in emergencies. Referrals from your primary care doctor are usually needed to see specialists. Going outside the network often results in higher out-of-pocket costs, and sometimes the full cost is your responsibility. - Preferred Provider Organization (PPO) Plans:
PPO plans encourage use of network providers but allow coverage for out-of-network care at a higher cost to you. Typically, you do not need referrals to see specialists, giving more flexibility than HMOs. - Private Fee-For-Service (PFFS) Plans:
PFFS plans resemble original Medicare more closely. You can visit any Medicare-approved provider who agrees to the plan’s terms. Some PFFS plans have networks with lower costs, while others do not. Prescription drug coverage may not be included, so you might need to enroll separately in Medicare Part D if your plan does not offer it. - Special Needs Plans (SNPs):
Designed for people with specific health conditions or limited incomes, SNPs often require care within a network and may assign a primary care provider or care coordinator. SNPs must include Part D drug coverage. You qualify if you:- Have a chronic illness
- Live in a nursing facility or require nursing care at home
- Are eligible for both Medicare and Medicaid
- Medicare Savings Account (MSA) Plans:
MSA plans combine a high-deductible health plan with a medical savings account you can use to pay for medical expenses. If you choose an MSA, you generally must have separate Part D drug coverage unless you already have a Medigap plan with prescription benefits.
Availability of Medicare Part C Plans
The types and number of Medicare Advantage plans vary by location. Some areas may offer multiple plan types, while others have limited or no Medicare Advantage options.
To find plans available in your area, visit medicare.gov/plan-compare and enter your ZIP code.
Part C Costs and Coverage Details
Medicare Part C plans provide all Part A and Part B benefits, but costs differ depending on the plan you select:
- Monthly Premiums:
Most Medicare Advantage plans charge a monthly premium in addition to your Part B premium. Some plans may have a $0 premium or cover your Part B premium entirely. MSA plans require you to pay your Part B premium but usually do not charge additional Part C premiums. - Copayments and Coinsurance:
These vary widely depending on the plan and services received. Generally, Medicare Advantage plans offer lower copayments for doctor visits and other services than standard Medicare. - Out-of-Pocket Limits:
All Medicare Advantage plans have a yearly maximum limit on your out-of-pocket costs for Part A and Part B services, protecting you from very high expenses. In 2025, this limit cannot exceed $9,350, though many plans set lower caps.
Medicare Part D
Medicare Part D, often called a drug coverage plan, offers prescription drug benefits to supplement Original Medicare (Parts A and B). Since Medicare Parts A and B do not cover most prescription medications, seniors can opt to enroll in a Part D plan to help pay for their prescription drug costs. Enrollment in Medicare Part D is optional—beneficiaries may choose to join a plan if they do not already have prescription drug coverage through another insurance source.
Medicare Part D plans are provided by private insurance companies approved by Medicare. Availability of specific Part D plans depends on where the enrollee lives, with different companies and plan options offered in different regions.
Each plan has its own list of covered drugs, called a formulary, which categorizes medications into different tiers based on factors like cost and specialization. Generally, generic drugs are the least expensive, followed by brand-name drugs, and then specialized medications which tend to cost the most.
Required Drug Coverage Classes
All Medicare Part D plans must cover at least two drugs from each of the following classes, ensuring that beneficiaries have access to key medications:
- Antidepressants
- Antipsychotics
- Anticonvulsants
- Cancer drugs
- HIV/AIDS drugs
- Immunosuppressants
This requirement guarantees that if one version of a drug is unavailable, the plan will cover an alternative, such as a generic or equivalent medication.
Understanding the Drug Formulary
Each insurance company offering a Part D plan designs its own formulary, which lists all the prescription drugs the plan covers. The formulary is usually organized by tiers, which help determine your copayment or coinsurance amounts. Lower tiers generally include generic drugs with the lowest copays, while higher tiers cover brand-name and specialty drugs that usually require higher out-of-pocket costs.
Costs and Coverage Details
Medicare Part D enrollees pay a monthly premium to maintain their drug coverage. Premium amounts vary widely depending on the plan and the enrollee’s location.
Income-Related Additional Costs
Seniors with higher incomes may be required to pay an extra charge called the Income-Related Monthly Adjustment Amount (IRMAA) on top of their standard Part D premium. For 2025, this surcharge applies if your income exceeds the following thresholds based on your tax return from 2 years ago:
If your filing status and yearly income in 2023 was | |||
File individual tax return | File joint tax return | File married & separate tax return | You pay each month (in 2025) |
$106,000 or less | $212,000 or less | $106,000 or less | your plan premium |
above $106,000 up to $133,000 | above $212,000 up to $266,000 | not applicable | $13.70 + your plan premium |
above $133,000 up to $167,000 | above $266,000 up to $334,000 | not applicable | $35.30 + your plan premium |
above $167,000 up to $200,000 | above $334,000 up to $400,000 | not applicable | $57.00 + your plan premium |
above $200,000 and less than $500,000 | above $400,000 and less than $750,000 | above $106,000 and less than $394,000 | $78.60 + your plan premium |
$500,000 or above | $750,000 or above | $394,000 or above | $85.80 + your plan premium |
Medigap Policies
Medigap policies are private insurance plans designed to help cover healthcare costs that Original Medicare (Parts A and B) doesn’t fully pay for. These can include expenses like copayments, coinsurance, and deductibles. Unlike Medicare itself, Medigap plans are sold by private insurance companies, not the federal government.
Medigap policies are sold on an individual basis. There are no group, family, or spousal Medigap plans. If a married couple wants Medigap coverage, each spouse must buy their own separate policy.
Prescription Drug Coverage
Medigap plans do not include prescription drug coverage. Seniors who need drug coverage must enroll in a separate Medicare Part D plan. (Some Medigap policies sold before January 1, 2006, may include prescription drug coverage, but no policies sold after this date offer drug benefits.) For more details, see the “Medicare Part D” section.
Standardized Plans
Medigap policies are standardized, meaning plans with the same letter offer the same basic benefits no matter which insurance company sells them. This makes it easier to compare plans. However, premiums and costs can differ between companies even for identical plan letters.
Comparing Medigap Policies
Except in Massachusetts, Minnesota, and Wisconsin, Medigap plans follow a uniform standard and are categorized by letter, similar to Medicare plans.
Comparing Medigap Policies
In all states except Massachusetts, Minnesota and Wisconsin, Medigap policies are standardized the same way. Like Medicare plans, Medigap policies are also categorized by letter.
The following Medigap plans are available:
- A
- B
- C*
- D
- F*
- G
- K
- L
- M
- N
Plan Differences
The main differences between these plans relate to:
- Deductibles
- Copayments
- Coverage of skilled nursing facility care
Insurance companies decide which Medigap plans they want to offer but must meet the following rules:
- They do not have to offer every Medigap plan.
- If they sell any Medigap plan, they must offer Plan A.
- If they offer plans beyond Plan A, they must also offer either Plan C or Plan F.
Medigap Benefits by Policy
Medigap policies are grouped into 10 different plans, each offering a unique set of benefits to Medicare recipients. The table below outlines the benefits included with each Medigap plan available in all states except Massachusetts, Minnesota, and Wisconsin. For details about Medigap policies in those three states, please see the “Medigap Policies in Massachusetts, Minnesota and Wisconsin” section of this guide.

What Is the Program of All-Inclusive Care for the Elderly (PACE)?
PACE is a collaborative effort between Medicare and Medicaid designed to help older adults receive comprehensive medical care while staying in their own communities instead of moving to nursing homes or long-term care facilities.
Who Can Benefit from PACE?
Older adults who join PACE gain access to a dedicated healthcare team that manages and coordinates all aspects of their care. The program covers a wide range of services approved by healthcare professionals, all aimed at meeting participants’ medical needs under Medicare and Medicaid.
Services Included in PACE
Some of the care and support services covered by PACE include:
- Primary care during adult day programs
- Regular doctor and specialist visits
- Emergency medical services
- Hospital stays and treatments
- Home health care
- Dental care
- Prescription medications
- Nutritional counseling
- Physical and occupational therapies
- Preventive care and social services
- Transportation to appointments
- Nursing home care when necessary
Availability of PACE Programs
Because PACE is managed locally and not run as a federal program, its availability varies by location. There are currently over 185 PACE programs operating across 33 states. However, even if your state has a PACE program, it might not serve your specific area.
Here are some of the states with active PACE programs:
- California, Florida, New York, Texas, and Washington
- Illinois, Ohio, Pennsylvania, Wisconsin
- And many others — 33 states in total
To check if PACE is offered near you, use the official locator tool here:
https://www.npaonline.org/pace-you/pacefinder-find-pace-program-your-neighborhood
Requirements to Participate in PACE
To qualify for PACE, individuals must:
- Be at least 55 years old
- Live within the service area of a local PACE provider
- Need a nursing home level of care, as determined by your state’s certification
- Be able to safely live in the community with support from PACE services
Applying for PACE
Since PACE programs are run independently in each state, the application process can vary. Generally, you’ll need to provide documentation such as:
- Proof of age (e.g., birth certificate)
- Proof of residence (e.g., utility bill, lease, mortgage statement)
- Medical documentation confirming the need for nursing home-level care
If you’re interested in joining PACE, start by finding out if a program operates in your area using the locator tool above. Then, contact the local PACE provider directly to get details on how to apply.
