Medicare Part A covers hospital stays, skilled nursing facility care, and some home health care services. You're eligible for Part A if you've worked and paid Medicare taxes for at least 10 years.
Medicare Part B, on the other hand, covers doctor visits, outpatient care, and medical supplies. You pay a monthly premium for Part B, which varies based on your income.
If you have Part A, you'll typically pay a $1,408 deductible for hospital stays and coinsurance of $341 per day for days 61-90.

Who Is Eligible
You're eligible for Medicare Part A and Part B if you meet one of the following criteria: You're 65 or older, or you're disabled and have received disability benefits from Social Security or Railroad Retirement Board (RRB) benefits.
To be specific, you're entitled to Medicare if you're 65 or above, or if you've been diagnosed with end-stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS, also known as "Lou Gehrig's disease").

The Social Security Administration (SSA) or Railroad Retirement Board (RRB) automatically enrolls some people in Medicare Parts A and B if they receive benefits from either of these administrations.
If you've received Social Security disability benefits for 24 months, you're automatically enrolled in Part A and Part B.
Here's a quick rundown of the eligibility criteria:
- You are aged 65 or above.
- You are disabled and have received disability benefits from Social Security or Railroad Retirement Board (RRB) benefits.
- You have been diagnosed with end-stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS, “Lou Gehrig’s disease”).
Premiums and Costs
Medicare Part A is usually free for people who have worked for at least 40 quarters while paying Medicare taxes, as well as their spouses.
The Part A premium varies depending on the number of quarters in which the person has paid Medicare taxes. For those who have paid Medicare taxes for 40 or more quarters, they do not pay a premium. However, if they have paid Medicare taxes for 30–39 quarters, their premium is $285 per month, and if they have paid Medicare taxes for fewer than 30 quarters, their premium for 2025 is $518 per month.

Most individuals will pay a monthly premium for Part B, with the amount varying depending on income. The standard monthly premium for Part B is $185, but individuals with higher incomes may be subject to an income-related adjustment, adding a fee to the monthly premium. The maximum Part B monthly premium is $628.90.
If you're paying a premium for Part A, you'll also need to pay the premium for Part B, which can range from $185 to $628.90 per month, depending on your income. Be sure to pay all monthly premiums and stay enrolled in Part B to keep premium Part A coverage.

Premium Based on Age
If you're 65 or older and eligible for Social Security or Railroad Retirement Board (RRB) benefits, you're in luck - your Medicare Part A premium is free.
You don't even need to file a separate application to get it, as long as you're receiving those benefits at least 4 months prior to turning 65.
However, if you're not receiving those benefits, you'll need to file an application for Medicare by contacting the Social Security Administration.
The application process is relatively straightforward, and you can expect Part A coverage to begin the month you turn 65, provided you file an application within 6 months of your birthday.
If you file after 6 months, your coverage will be retroactive for 6 months, but you'll still need to pay any premiums that were due during that time.
Here's a breakdown of the Part A premium costs:
Costs and Deductibles
If you're admitted to the hospital, you might pay a deductible and daily coinsurance for extended stays. In 2023, this means you'll have to cover these costs out of pocket.
Many people receive Part A without paying a premium, but this doesn't mean they're off the hook for all costs. If you do receive Part A without paying a premium, you'll still need to pay deductibles and coinsurance.

Medicare Part A has deductibles and coinsurance that you'll need to pay, even if you don't pay a premium. This can add up quickly, so it's essential to understand what you're responsible for.
Original Medicare (Parts A and B) has its own set of costs that you'll need to cover. This can include copayments, coinsurance, and deductibles that aren't covered by your premium.

The CMS-4040 form is specifically for individuals who aren't entitled to social security or railroad retirement board benefits and want to enroll in Part B.
People with End-Stage Renal Disease (ESRD) should use the CMS-43 form to enroll in both Part A and Part B.

Choosing the Right Plan
Part A and Part B make up Original Medicare, and understanding their differences is crucial for making an informed decision.
Part A covers many costs of inpatient care, so if you have a hospital stay planned, this part might be the way to go.
Part B primarily covers the costs of outpatient treatment and preventive care, such as doctor visits, medical equipment, and some prescriptions.
The two parts have different out-of-pocket costs, including deductibles and coinsurance, so be sure to factor those into your decision.
Original Medicare can be a good option if you want a simple, straightforward plan with minimal paperwork.
However, if you're looking for more comprehensive coverage, you may want to consider other options, like Medicare Advantage or Medicare Supplement plans.
Ultimately, choosing the right plan depends on your individual needs and circumstances, so take the time to research and compare your options carefully.
Special Circumstances
If you're receiving a pension from a government agency, you may be eligible for Medicare Part A premium-free. This is because Medicare considers these pensions to be taxable income.
Some people may be exempt from paying Medicare Part B premiums due to their income level or other factors. This can include individuals with disabilities, or those who are receiving assistance from programs like Medicaid or the Supplemental Security Income (SSI) program.
If you're receiving Social Security Disability Insurance (SSDI) benefits, you'll automatically be enrolled in Medicare Part A and Part B.

On Disability
If you're receiving disability benefits, you're in a special situation when it comes to Medicare. You're automatically entitled to Part A after receiving disability benefits for 24 months.
If you're a disabled federal, state, or local government employee, you may get deemed entitlement to disability benefits and automatically entitled to Part A after being disabled for 29 months.
The Initial Enrollment Period (IEP) for people under 65 who become entitled to Medicare based on disability is a bit different. It starts 3 months before the 25th month of disability benefit entitlement and ends 3 months after.
For most people, coverage will begin the month after enrolling during their IEP.

Your deductible is an annual amount you must spend out of pocket before Medicare starts to fund your treatments. This can vary depending on the type of coverage you have.
