How Much Does Medicare Part A Cost?
The cost of Medicare Part A premiums depends on whether you or your spouse paid income taxes, and for how long. Most individuals won’t pay a Part A premium. Here are some essential facts about Part A and what it costs.
Medicare Part A Premiums
Medicare calculates Part A premium costs by how long you or your spouse have paid Medicare taxes.
Here is an explanation of monthly premiums for Plan A in 2023:
$0/mo.
If you or your spouse paid Medicare taxes for 10 years or more
$278/mo.
If you or your spouse paid Medicare taxes for more than 7.5 years but less than 10
$506/mo.
If you paid Medicare taxes for fewer than 7.5 years
Medicare Part A Deductible
Most Part A costs come from the inpatient hospital deductible. Inpatient care provided at a hospital or skilled nursing facility will require you to pay the annual deductible.
For the year 2023, the Plan A deductible increased from 2022:
- Medicare Part A deductible 2022: $1,556
- Medicare Part A deductible 2023: $1,600
Medicare Part A Co-insurance
Your Part A deductible will cover the first 60 days [i] of inpatient care. You’re responsible for a daily coinsurance amount beyond 60 days. The type of facility and how long you stay affect the daily coinsurance amount.
Part A coinsurance increases when your length of stay in a facility increases:
- 0 to 60 days
- 61 to 90 days
- You have a lifetime limit of reserve days to use if your stay lasts longer than 90 days.
Medicare Part A daily coinsurance rates for 2023:
- Days 0-60: $0
- Days 61-90: $400 per day
- Lifetime Reserve Days: $800 per day
If you need skilled nursing care, your daily coinsurance amount is $200 for days 21-100.

Part B Late Enrollment Penalty
The last factor that determines your Part B premium amount is when you sign up. If you enroll as soon as you’re eligible for Part B, your monthly premium will follow the formulas above.
If you sign up later, you may pay a 10% penalty for each 12-month period you missed. If you enroll at 67 (when eligible at 65), your monthly premium payment will be 20% higher than the table above.
Medicare Part B Deductible
All Medicare enrollees pay the same monthly deductible. Like your premium, the annual deductible adjusts each year. For example:
- Medicare Part B deductible 2021: $203
- Medicare Part B deductible 2022: $233
- Medicare Part B deductible in 2023: $226
Medicare Part B Coinsurance
Once you meet your deductible, you’ll pay 20% of all Medicare-approved services you receive. Services can include doctor services, outpatient therapy and durable medical equipment.
For example: If your doctor charges $100 for visits, you’ll pay 20% ($20) after you’ve met your deductible.

What Else Should I Consider?
Original Medicare (Parts A and B) is most common and has remained popular over the years. There are, however, other options that you may want to consider. For example:
Medicare Advantage: Also called Medicare Advantage Plan (Part C) , this is an alternative to Original Medicare that provides additional benefits like dental, vision and prescription drug coverage. These plans are regulated by Medicare but provided through private insurance companies.
Medigap: Medicare Supplement Insurance (Medigap) fills the holes in your policy that aren’t covered by Original Medicare. These are purchased in addition to your Medicare coverage and are offered by private insurance companies.
Medicare Part D: Standalone, private prescription drug insurance that works with Original Medicare. With Medicare Prescription Drug Plan (Part D) , you can enroll at the same time as Original Medicare, or during the Medicare Open Enrollment Period each year from October 15 to December 7.
Medicare & Medicaid: Medicaid is a public health insurance option designed for people with low-income or limited resources. If you qualify for both Medicare and Medicaid, you are considered “dual eligible” and can receive greater financial assistance.
