Updated Enrollment Periods for 2026
Most Medicare enrollment periods remain consistent for 2026, but CMS has introduced additional flexibility for beneficiaries facing coverage disruptions or life-changing events.
Annual Enrollment Period (AEP)
The Annual Enrollment Period remains unchanged. During this window, you can switch from Original Medicare to Medicare Advantage (or vice versa), change drug plans, or enroll for the first time if eligible.
Special Enrollment Periods (SEP)
CMS has expanded Special Enrollment Period eligibility to help beneficiaries affected by plan discontinuations or involuntary coverage loss. Late enrollees facing plan withdrawals now have extended time to sign up.
Other Key Enrollment Windows
Medicare Advantage Open Enrollment Period (OEP)
Medicare Advantage enrollees can switch to another MA plan or return to Original Medicare (plus add Part D).
Initial Enrollment Period (IEP)
7-month window to enroll in Medicare when you first become eligible (typically around your 65th birthday).
General Enrollment Period (GEP) Alternative
If you miss your IEP and lose employer coverage, you have an 8-month SEP to enroll without penalties.
Policy Changes for 2026
Beyond enrollment windows, CMS is implementing several important policy updates designed to improve beneficiary protections, streamline administrative processes, and expand access to care.
Streamlined Late Enrollment Appeals
CMS has simplified the appeals process for beneficiaries seeking to waive late enrollment penalties. New online forms and clearer guidance help you demonstrate qualifying events (e.g., creditable coverage, employer delays) more easily.
Continued Telehealth Access
Medicare will continue covering telehealth services at expanded levels through 2026. This includes mental health counseling, routine check-ups, and chronic disease management via audio-video platforms.
New CMS Compliance Standards for Plan Marketing
Starting in 2026, Medicare Advantage and Part D plans must follow stricter rules for marketing materials and sales tactics. This includes clearer disclosure of network restrictions, formulary limitations, and prior authorization requirements.
Enhanced SHIP Counseling Resources
State Health Insurance Assistance Programs (SHIP) receive increased funding to help beneficiaries navigate 2026 changes. Free, unbiased counseling is available in all states for plan selection and appeals.
Avoiding Late Enrollment Penalties
Missing enrollment deadlines can result in permanent premium increases and gaps in coverage. Here is how to protect yourself:
Understanding Part B and Part D Penalties
Part B Late Enrollment Penalty
If you do not enroll in Part B when first eligible (and do not have creditable employer coverage), you will pay a 10% penalty for each 12-month period you were eligible but not enrolled. This penalty lasts for as long as you have Part B.
Part D Late Enrollment Penalty
The Part D penalty is calculated as 1% of the national base beneficiary premium for each month you were eligible but did not enroll. For 2026, this adds approximately $0.35–$0.40 per month per missed month. It also lasts for as long as you have Part D.
How to Avoid Penalties
- 1.Enroll during your Initial Enrollment Period (3 months before through 3 months after your 65th birthday month)
- 2.Maintain creditable coverage (employer, union, VA, TRICARE) if delaying enrollment
- 3.Sign up within 8 months of losing employer coverage using your SEP
- 4.Set reminders well before Open Enrollment or SEP deadlines
What If You Already Have a Penalty?
Late enrollment penalties are permanent and cannot be waived unless you can prove you had creditable coverage or were misled by your employer or plan. File an appeal using Form CMS-L564 (Part B) or contact your Part D plan for reconsideration.

Frequently Asked Questions About 2026 Enrollment
When can I enroll in Medicare in 2026?
You can enroll during your Initial Enrollment Period (3 months before through 3 months after your 65th birthday), the Annual Open Enrollment Period (October 15–December 7), or during a Special Enrollment Period if you qualify due to life changes like losing employer coverage. Read our enrollment timeline guide for specific deadlines.
What are the new CMS compliance rules for 2026?
CMS now requires brokers and insurers to provide clearer disclosures about plan networks, prior authorization requirements, and formulary changes. Marketing materials must avoid misleading claims, and beneficiaries must receive written confirmations of all enrollment decisions.
Can I still use telehealth in 2026?
Yes. Medicare extended telehealth flexibilities through 2026, allowing virtual visits for mental health, physical therapy, and many primary care services. Check with your provider about which services are available remotely. Learn more in our 2026 telehealth update.
Will I face penalties if I delay enrollment?
Yes, if you delay Part B or Part D enrollment without creditable coverage. Part B penalties add 10% per year you were eligible but not enrolled. Part D penalties add 1% of the national base premium per month of delay—and both are permanent. See our Medicare 101 guide for details on avoiding penalties.
What if my Medicare Advantage plan is discontinued in 2026?
If your plan is discontinued, CMS will notify you and provide a Special Enrollment Period to choose a new plan. You can switch to another Medicare Advantage plan, return to Original Medicare with a Medigap supplement, or explore standalone Part D coverage.
