Important Enrollment Dates
The timeline for Medicare open enrollment follows the same annual schedule:
- October 1, 2025: Updated plan information becomes available for review.
- October 15, 2025: Enrollment officially opens.
- December 7, 2025: Enrollment closes.
- January 1, 2026: New coverage begins.
Anyone looking to make changes should take action before the deadline. Missing the enrollment window typically means keeping your current plan for another year unless you qualify for a special enrollment period.
What’s Changing in 2026
Each year, Medicare evaluates and updates costs, coverage rules, and plan availability. For 2026, several confirmed cost adjustments are now official.
Updated Premiums and Deductibles
- The standard monthly premium for Medicare Part B has increased to $202.90.
- The annual Part B deductible has risen to $283.
- The Part A inpatient hospital deductible is now $1,736 for each benefit period.
These confirmed increases mean many beneficiaries will pay more in 2026 for outpatient care, hospital treatment, and medical services.
Plan Renewals and Coverage Rules
If you are already enrolled in a Medicare Advantage or Part D prescription plan, your coverage will typically continue automatically unless you choose to change it. However, automatic renewal does not guarantee that your 2026 coverage remains the same. Insurance companies adjust:
- Provider networks
- Prescription drug formularies
- Monthly premiums
- Annual out-of-pocket limits
For this reason, reviewing your Annual Notice of Change (ANOC) letter is essential. This document arrives each fall and outlines how your current plan will change for the upcoming year.
Your Options During Open Enrollment
During Medicare Open Enrollment, you can:
- Switch from Original Medicare to Medicare Advantage
- Change from Medicare Advantage back to Original Medicare
- Switch Medicare Advantage plans
- Join, drop, or change a Medicare Part D prescription drug plan
If you do nothing, most plans will automatically carry over into 2026 provided you remain eligible.
Steps to Prepare Before Choosing a Plan
To make the most informed decision for 2026:
- Review your current medical needs.
Have your prescriptions, preferred doctors, and expected treatments changed? - Check plan changes.
Premiums, co-pays, and benefits may not match last year’s terms. - Compare available plans in your ZIP code.
Plan options and costs vary widely by region. - Evaluate total yearly cost—not just the premium.
Deductibles, drug tiers, and out-of-pocket caps can significantly impact overall spending. - Decide before December 7.
Late changes cannot be processed after the deadline.
Short, clear comparison and preparation can help beneficiaries avoid overpaying or losing access to essential care.
Who Should Take Extra Time to Review Coverage?
Some groups are more likely to benefit from switching plans during the 2026 enrollment period:
- Beneficiaries whose medications changed in 2025
- Anyone who recently changed doctors or medical conditions
- People enrolled long-term in the same Advantage plan without recent review
- Individuals moving to another state or county
- First-time Medicare Advantage or Part D enrollees
Even if you feel satisfied with your current plan, reviewing available updates ensures nothing important has shifted.
