Short answer
Yes. If you are eligible for the Medicare Annual Enrollment Period, you can make another eligible Medicare Advantage or Part D choice before December 7, even if you already submitted an application. Generally, the last valid enrollment request determines the coverage that takes effect. For the 2026 fall period, confirm the plan receives your request by December 7, 2026, and verify your January 1, 2027 coverage with the plan or Medicare.
What another fall enrollment choice means
If you notice a problem with your first choice, you can review another eligible option while Annual Enrollment remains open. A second decision deserves the same careful review as the first. Check the complete plan name, coverage year, service area, and application details. CMS explains that the last enrollment request generally determines the intended choice when multiple requests share an effective date.
For example, if you apply in October and later discover that an important specialist is outside the selected network, review the issue before sending another application. Confirm the exact office location and next year’s plan, rather than relying on the insurance company’s name.

Confirm the deadline and your final enrollment
The fall period runs October 15 through December 7, 2026. An eligible request received by the plan by the deadline takes effect January 1, 2027. Keep the new reference number and ask the plan or 1-800-MEDICARE which enrollment is recorded for January. Do not rely only on the arrival order of letters or cards.
If your goal is to cancel a pending application and keep your current coverage, contact the plan promptly for its cancellation process and confirm the outcome. Do not assume that ignoring a card cancels enrollment. Ask for written confirmation or a call reference.

Review doctors, prescriptions, and other coverage first
Use our Brandon Medicare doctor and hospital network guide to check your providers. Then compare the exact drugs and pharmacy locations using the 2027 prescription cost comparison guide. Look at the full coverage arrangement, including medical costs and drug coverage.
Medigap enrollment protections and employer or retiree benefits have separate rules. Fall Annual Enrollment does not automatically guarantee Medigap acceptance without underwriting. Ask your benefits administrator about employer or retiree coverage before changing it, and confirm how a standalone drug plan could affect Medicare Advantage.

What changes after December 7?
The fall window closes on December 7. From January 1 through March 31, Medicare Advantage Open Enrollment gives eligible people already in Medicare Advantage certain change options. It is not a second general enrollment period for everyone with Original Medicare and Part D. A Special Enrollment Period may apply in a qualifying situation.
If you are unsure which rule applies, contact Medicare or your plan. Do not assume another application will be valid simply because you can access an online enrollment form.
