Key Takeaways
-
In 2025, Medicare coverage includes new cost protections and simplified phases in drug plans, making it more predictable for beneficiaries.
-
Understanding how each part of Medicare works—Part A, B, C, and D—can help you better plan for your health care needs and avoid unexpected expenses.
Understanding the Foundation of Medicare
Medicare continues to serve as the primary health insurance program for Americans aged 65 and older and younger people with certain disabilities. In 2025, it remains divided into four main parts:
-
Part A (Hospital Insurance)
-
Part B (Medical Insurance)
-
Part C (Medicare Advantage)
-
Part D (Prescription Drug Coverage)
Each part functions differently, and knowing how they work together can help you make informed decisions.
What You Should Know About Medicare Part A in 2025
Medicare Part A covers inpatient hospital care, skilled nursing facility care, some home health care, and hospice. If you or your spouse paid Medicare taxes for at least 10 years, you generally don’t pay a premium for Part A.
Here’s what Part A looks like in 2025:
-
Inpatient hospital deductible: $1,676 per benefit period
-
Coinsurance:
-
Days 1-60: $0
-
Days 61-90: $419 per day
-
Lifetime reserve days (up to 60 days total): $838 per day
-
-
Skilled nursing facility care:
-
Days 1-20: $0
-
Days 21-100: $209.50 per day
-
Keep in mind, these amounts reset per benefit period, not annually.
Medicare Part B Costs and Coverage
Part B helps cover outpatient services, including doctor visits, preventive services, durable medical equipment, and outpatient procedures. Most people pay a monthly premium unless covered under other arrangements.
For 2025:
-
Monthly premium: $185 (standard amount)
-
Annual deductible: $257
-
After you meet the deductible, you typically pay 20% of the Medicare-approved amount for most services.
Preventive services such as screenings, vaccinations, and annual wellness visits are generally covered with no out-of-pocket costs.
What Changed in Medicare Part D This Year
Medicare Part D underwent a major shift in 2025. If you rely on prescription drugs, this part is crucial.
Key updates include:
-
Out-of-pocket cap: You won’t pay more than $2,000 annually for covered drugs.
-
No more coverage gap: The old “donut hole” phase is gone. Now there are three simplified phases:
-
Deductible phase (up to $590)
-
Initial coverage phase
-
Catastrophic phase (after $2,000 out-of-pocket)
-
This change brings much-needed predictability for those with high drug costs.
Medicare Advantage Plans in 2025
Medicare Advantage (Part C) combines Part A and Part B and usually includes Part D, along with extra benefits like dental or vision. These are offered through private insurers and may have different out-of-pocket costs and network rules.
Although prices vary, here are general characteristics:
-
Must include all services covered under Original Medicare
-
Often has a yearly out-of-pocket max for in-network care, typically under $9,350
-
May include extra perks, but those vary widely
You should always review plan details carefully to ensure it fits your medical needs.
How Enrollment Works in 2025
Enrolling in Medicare happens during specific periods, and missing one could delay coverage or result in penalties.
Initial Enrollment Period (IEP)
Begins three months before your 65th birthday, includes your birth month, and ends three months after.
General Enrollment Period (GEP)
If you miss IEP, you can enroll January 1 – March 31. Your coverage starts July 1.
Annual Open Enrollment (AEP)
Runs October 15 – December 7 each year. You can switch, drop, or join new plans. Changes become effective January 1.
Medicare Advantage Open Enrollment (MA OEP)
From January 1 – March 31, you can switch to another Advantage plan or return to Original Medicare.
Special Enrollment Periods (SEPs)
Certain life events like losing employer coverage or moving can allow enrollment outside of standard windows.
Important Updates on Supplemental Coverage
If you’re on Original Medicare (Parts A and B), you can add a Medicare Supplement Insurance policy (Medigap) to help pay your share of costs. Medigap policies are standardized, and each plan covers different things.
In 2025:
-
Medigap does not cover prescription drugs. You must enroll in Part D for that.
-
You must have Part A and Part B to be eligible.
-
There may be a waiting period if you apply outside of your Medigap Open Enrollment Period.
Coordinating Medicare with Other Coverage
Many people delay enrolling in Medicare if they have employer coverage. In 2025, the same rules apply:
-
If your employer has 20 or more employees, your group health plan pays first.
-
If fewer than 20 employees, Medicare pays first.
When you retire, you typically have 8 months to enroll in Part B without penalty.
Medicare and Health Care Costs in 2025
While Medicare covers a broad range of services, it doesn’t cover everything. You’ll still be responsible for:
-
Monthly premiums (Part B and possibly Part D or Medicare Advantage)
-
Deductibles, coinsurance, and copayments
-
Services not covered by Medicare, such as most dental, vision, and hearing care
Cost-saving tips include:
-
Using providers who accept Medicare assignment
-
Reviewing your Part D plan annually
-
Coordinating benefits if you have other insurance
What Isn’t Covered by Medicare
Even in 2025, Medicare doesn’t cover every medical need. You should be aware of what falls outside its scope:
-
Long-term custodial care (e.g., assisted living)
-
Routine dental exams and procedures
-
Hearing aids and most hearing exams
-
Eye exams for glasses
-
Overseas medical care (in most cases)
You may need separate insurance or savings to handle these expenses.
How Medicare Coordinates With Medicaid
If your income and resources are limited, you might qualify for both Medicare and Medicaid. Known as dual eligibility, this can significantly reduce your costs.
In 2025, Medicaid may cover:
-
Part B premiums
-
Out-of-pocket costs like deductibles and copayments
-
Additional services not covered by Medicare
Programs like the Medicare Savings Program and Extra Help can provide added financial relief.
Staying Ahead with Preventive Care
Preventive care is one of Medicare’s strongest areas. It focuses on early detection and wellness.
Covered preventive services in 2025 include:
-
Annual wellness visits
-
Flu, COVID-19, and pneumonia vaccines
-
Screenings for cancer, cardiovascular conditions, and diabetes
Taking full advantage of these services helps you stay healthy and avoid larger medical bills down the road.
The Big Picture: Medicare in 2025
Medicare in 2025 continues to evolve, but the core purpose remains the same—providing dependable health coverage for older adults and certain individuals with disabilities. The new drug cost protections and removal of the coverage gap are welcome changes. However, it’s still essential to review your coverage annually and understand how the pieces fit together.
