Medicare Open Enrollment: Dates, Decisions, and How to Choose the Right Coverage

What is Medicare Open Enrollment

Medicare Open Enrollment is a yearly window from October 15 to December 7 when you can review and change your Medicare coverage for the following year. Changes take effect on January 1. Plans often update premiums, deductibles, drug formularies, and provider networks each year, so even if you were happy last year, it is smart to check that your plan will still fit your needs.

During this period you can:

  • Switch between Original Medicare and Medicare Advantage (Part C)
  • Change from one Medicare Advantage plan to another
  • Add, drop, or change a Part D prescription drug plan
  • Review whether your Medigap (Medicare Supplement) policy still fits your budget and needs

If you do not make changes, you typically stay in your current plan by default. Still, a quick check can save money or prevent surprises at the pharmacy or doctor’s office.

Why this season can feel overwhelming

If you are on Medicare, you may notice a flood of marketing during this time. Many people receive calls, texts, emails, and mailers from different Medicare Advantage organizations in their county. This is normal during Open Enrollment. You do not have to respond to every solicitation. You can take a calm, stepwise approach that starts with your needs and your current doctors and medicines.

What to know about current costs and next year’s projections

  • For 2025, CMS set the standard Part B premium at $185 per month and the annual Part B deductible at $257.
  • For 2026, the official amounts will be announced later in the fall, but the 2025 Medicare Trustees Report projects a standard Part B premium of $206.50 and a Part B deductible of $288. Projections can change, but they are useful for planning ahead.

If you have a Medigap (supplement) plan, it may cover the Part B deductible depending on which plan you have and when you first enrolled. Always confirm your benefits before January 1 so you know what you will pay when you see a clinician.

Choose the right plan. Check costs, drugs, and in-network doctors.

What you can change during Open Enrollment

If you have Original Medicare

You can join a Part D prescription drug plan or switch to a different one. You can also switch from Original Medicare to a Medicare Advantage plan that operates in your service area.

If you have a Medicare Advantage plan

You can switch to a different Medicare Advantage plan, or you can return to Original Medicare and optionally add a Part D plan. Some people also look at Medigap policies to help cover out-of-pocket costs under Original Medicare. Availability and underwriting rules for Medigap vary by state and timing, so check early.

If you have limited income

You may qualify for Extra Help with Part D drug costs or for a Medicare Savings Program that can pay your Part B premium. These programs can significantly lower monthly and pharmacy costs.

Step-by-step plan to review your coverage

1) Make a quick list of your needs

  • Your doctors and clinics you want to keep
  • Your prescriptions, including dose and pharmacy
  • Your common services, such as physical therapy, diabetes supplies, or imaging

2) Check what is changing for next year

  • Premiums and deductibles for your plan
  • Drug formulary tiers and prior authorization rules
  • Provider network status for your clinicians and hospitals
  • Out-of-pocket maximum for Medicare Advantage plans

3) Compare plans using trusted tools

Use the official Medicare plan comparison tool to check premiums, estimated drug costs, and in-network providers. Re-run your medications to see total yearly costs, not just the premium.

4) Watch for tradeoffs that matter

  • Low premiums can still mean higher copays or narrower networks
  • A plan with your doctors out of network can lead to big bills
  • Even small formulary changes can raise pharmacy costs

5) Confirm before you switch

  • Call the plan to confirm your providers, hospitals, and medicines
  • Save written verification, such as an email or plan finder printout
  • Review any prior authorization requirements for therapies you use

6) Get free, unbiased help if you want it

Every state offers trained counselors who can walk through options with you at no cost. You can also apply for Extra Help with Social Security if you qualify.

What is different or noteworthy this year

  • Marketing volume is high. Expect more calls and mail during October and November. You can ignore marketing and go straight to official resources.
  • Part D changes continue. Formularies and preferred pharmacies can shift each year. Always re-check your medications and the pharmacies you use.
  • Costs trend upward. The Trustees project increases in standard Part B costs for 2026. Plan ahead in your budget and evaluate if Extra Help or a Medicare Savings Program could lower your expenses.

How to protect your doctors and prescriptions

  • Doctors and hospitals: If you are considering Medicare Advantage, verify that your primary care clinician, specialists, and hospital are in network for the exact plan name and plan year.
  • Prescriptions: Enter each drug in the official plan finder to see if it is covered, the tier, and whether it needs prior authorization or step therapy. Look at your expected yearly total cost, not only the monthly premium.
  • Preferred pharmacies: Some plans have lower copays at certain pharmacies. Switching to a preferred pharmacy can cut costs.
  • Mail order: Many plans offer savings with mail-order for 90-day supplies. Confirm shipping times so you do not run out.

Budget tips for 2025 and planning for 2026

  • Build your monthly budget around the 2025 Part B premium of $185 and your plan’s premiums.
  • If you rely on costly medications, compare Part D plans each year. A small tier change can increase your yearly spend.
  • For 2026, use the Trustees’ projected Part B premium of $206.50 and deductible of $288 as a planning estimate until CMS publishes final amounts later this fall.
  • If your income is limited, look at Extra Help for Part D and state Medicare Savings Programs that may pay your Part B premium.
