These periods are the Annual Enrollment Period (AEP) and the Open Enrollment Period (OEP).

What Is AEP and OEP? The Medicare Annual Enrollment Period (AEP) and the Medicare Advantage Open Enrollment Period (OEP) are timeframes for Medicare beneficiaries to review and update their healthcare coverage.

Why should you review your healthcare coverage?

Out-of-pocket costs, such as deductibles and premiums, may shift from year to year, potentially impacting your budget. Plans often change annually, copays, covered medications, and provider networks. Here's is a short summary about enrollment periods:

Annual Enrollment Period (AEP) AEP lasts every year from October 15 to December 7 and is open to all Medicare beneficiaries.

During this time, you can:

Switch from Original Medicare to a Medicare Advantage plan (or vice versa). Enroll in, drop, or change your Medicare Part D prescription drug plan. Change from one Medicare Advantage plan to another. Example: If your current plan doesn’t meet your prescription drug needs, AEP is the time to enroll in a Part D plan that offers better coverage for your prescriptions.

Open Enrollment Period (OEP) OEP runs annually from January 1 to March 31 and is limited to individuals already enrolled in a Medicare Advantage plan.

During OEP, you can:

Switch to another Medicare Advantage plan (with or without drug coverage). Return to Original Medicare and, if needed, add a standalone Part D plan. Important: OEP does not allow you to enroll in a Medicare Advantage plan for the first time or switch from Original Medicare to Medicare Advantage.

If you're unhappy with your current Medicare Advantage plan or its network, OEP is your chance to adjust your plan without waiting another year

AEP vs. OEP: Key Differences Key enrollment period differences are:

1. Timing and Eligibility AEP: Occurs every year from October 15 to December 7 and is available to all Medicare beneficiaries. OEP: Runs annually from January 1 to March 31 but is limited to individuals already enrolled in a Medicare Advantage plan. 2. Purpose and Flexibility AEP: This period is for all Medicare beneficiaries who evaluate and make significant changes to their overall coverage. OEP: Provides flexibility for Medicare Advantage enrollees to adjust their plans based on their changing needs or dissatisfaction with their current coverage. Tip: Use AEP to plan ahead for the upcoming year and OEP to address any immediate issues with your Medicare Advantage plan.

Common Mistakes to Avoid During AEP and OEP Most common mistakes during both periods include:

1. Misunderstanding what you can do during each enrollment period. AEP allows broad changes, including switching from Original Medicare to Medicare Advantage or adding Part D coverage, while OEP only applies to Medicare Advantage enrollees.

Tip: Mark both periods on your calendar and carefully plan ahead. Use AEP for major adjustments, like switching to a different type of Medicare coverage, and reserve OEP for fine-tuning Medicare Advantage plans. If you're unsure about your options, tools like Healthpilot can provide personalized guidance to help you navigate these periods with ease.

2. Waiting Too Long to Make a Decision If you’re undecisive about which period to use for enrolling, there’s a chance you’ll miss the deadlines for AEP (December 7) or OEP (March 31).

Missing the deadline could mean you stay in your current plan that no longer meets your needs until you qualify for another enrollment period.

Tip: Start reviewing your plan options early in the enrollment period and set calendar reminders before the deadline.

3. Ignoring Provider Network Changes Overlooking changes to your plan’s provider network can result in losing access to your preferred doctors or hospitals.

Networks can change yearly, and receiving care from out-of-network providers often leads to higher out-of-pocket costs or no coverage at all.

Tip: Before making any changes or staying with your current plan, verify that your preferred providers and specialists are still in-network to avoid unexpected costs or disruptions in care.

Medicare Advantage plans rely on contracted provider networks to manage costs and offer comprehensive care
