How much does Medicare cost in 2025? Parts A, B, C and D

Whether you’re new to Medicare or could use a refresher, here are some common Medicare terms explained:

Coinsurance is a percentage of your medical and drug costs you may be required to pay as your share of costs for medical services or supplies (for example, 20% of the cost of a prescription drug).

Copayment is a specific dollar amount you may be required to pay as your share of the cost for medical services or supplies (for example, a $10 copay for a healthcare provider visit).

Deductible is the amount you pay for medical services or prescription drugs in a plan year before your plan begins to pay for benefits.

Premium is the amount you are required to pay each month to Medicare or your private insurer for your healthcare coverage.

  • After the maximum 60 lifetime reserve days are exhausted, there is no more coverage under Part A for inpatient hospital stays.

What it costs:¹

• Most 2025 Medicare members must pay a monthly premium of $185.
• If you don't enroll in Medicare Part B as soon as you are eligible, you could be assessed a late enrollment penalty when you do enroll. Medicare late enrollment penalties are imposed by the federal government (Medicare), not private insurance companies like Humana. 
  • The penalty could be as high as a 10% increase in your premium for each 12-month period that you were eligible but not enrolled.

Your Part B premium could be higher depending on your income.

Other Part B costs for 2025:¹

• There is a $257 annual deductible for Medicare Part B in 2025. After the deductible, you’ll pay a 20% copay for most doctor services while hospitalized, as well as for DME and outpatient therapy.
• There is a 20% copay of the Medicare-approved amount for doctor visits to diagnose a mental health condition after the deductible.
  • If you receive these services at a hospital outpatient department or clinic, additional copays or coinsurance amounts may apply.
• There is a 20% copay of the Medicare-approved amount for outpatient services after the deductible.

What it helps cover:

• Medicare Advantage plans are required by law to provide—at minimum—the same coverage, benefits and rights provided by Original Medicare Part A and Part B, with the exception of hospice care.
• Many Medicare Advantage plans also choose to offer prescription drug coverage, as well as coverage for routine dental, vision and hearing benefits.

What it costs:¹

• Medicare Advantage plans are offered by private insurance companies contracted by the federal government, so they vary in cost, coverage, deductibles and copays.
• Many Medicare Advantage plans offer affordable or low premiums plus a variety of coverages and benefits not offered by Original Medicare (Medicare Parts A and B).

What it helps cover:

• Medicare Part D helps cover prescriptions drugs.
• Plan premiums, the drugs that are covered, deductibles, coinsurance and copays will vary by Part D plans, so you should check and compare plans each year based on your needs, the prescription drugs you take, etc.

What it costs:¹

• Like Medicare Advantage (Part C), prescription drug plans (Part D) are offered by private insurance companies contracted by the federal government.
  • Plans vary in cost, coverage, deductibles and copays.
• There’s a Part D late-enrollment penalty if you don’t enroll in an approved Medicare drug plan (including a Medicare Advantage plan) when you’re first eligible, unless you have other creditable prescriptions drug coverage.
  • Medicare calculates the penalty by multiplying 1% of the "national base beneficiary premium" ($36.78 in 2025) times the number of full, uncovered months you didn't have Part D or creditable coverage.
  • This penalty is assessed when you enroll in a Part D plan, and you’ll pay the higher amount for as long as you keep your Part D coverage.
• Your Part D premium could be higher depending on your income.

Medicare Supplement plans aare sold by private insurance companies, so prices, or premiums, can vary. 2 insurance companies may charge different prices for the exact same coverage.

Costs that you pay with any Medigap plan include:

• Monthly Medigap plan premium
• Medicare Parts A and B premiums if required
• Medicare deductibles, copayments and coinsurance if not covered by the Medigap plan (based on the plan you choose)
