Picked the Wrong Medicare Advantage Plan? You Can Change It by March 31

By Justin Scheiner on March 3, 2026



If you enrolled in a Medicare Advantage plan during Annual Enrollment (AEP) and quickly realized it’s not a good fit, you’re not stuck for the whole year.

The Medicare Advantage Open Enrollment Period runs January 1 through March 31, and it gives many people already enrolled in Medicare Advantage a chance to make one change.

Below is a plain-English guide to what you can change, what you can’t, and the 3 things you should check before you switch—especially if you’re in Fort Lauderdale / Broward County, where networks and referrals can make or break your experience.

Who Medicare Advantage Open Enrollment applies to

This open enrollment period is only for people who are already enrolled in a Medicare Advantage plan. If you’re in Original Medicare right now (Parts A & B) and you’re trying to newly join Medicare Advantage, this is typically not the window for that – your options depend on other enrollment periods.

What you CAN do during Medicare Advantage Open Enrollment (through March 31)

Option 1: Switch to another Medicare Advantage plan

You can switch from one Medicare Advantage plan to another (with or without drug coverage).

Option 2: Drop Medicare Advantage and return to Original Medicare

If you leave Medicare Advantage and go back to Original Medicare, you can also join a standalone Part D prescription drug plan if you need drug coverage.

When does the change start?

Changes made during this period generally take effect the first day of the month after the plan receives your request.

What you generally CANNOT do during this period

This is where people get tripped up:

– If you’re not currently enrolled in a Medicare Advantage plan, you generally can’t use this enrollment period to join Medicare Advantage.

– If you’re in Original Medicare, this period generally isn’t used to switch standalone Part D plans the way people assume.

If you’re not sure which category you’re in, it’s worth confirming before submitting any changes.

Common reasons people switch in Broward County

If any of these sound familiar, you’re not alone:

1) Your doctors or hospital aren’t in-network

This happens constantly—especially if a plan was chosen without verifying providers first.

2) Referrals are required (and it’s slowing everything down)

Many HMOs require PCP referrals for specialists. If you’re used to booking specialists directly, this can be frustrating fast.

3) Prescriptions cost more than you expected

Even when the monthly premium looks great, the formulary/tiering/pharmacy rules can change your real yearly cost.

4) Copays or maximum out-of-pocket don’t fit your situation

If you use care frequently, the difference between plan designs can be significant.

Before you switch: the 3 checks that prevent most bad enrollments

If you only do three things, do these:

Check #1: Doctors + facilities

– Confirm your PCP and specialists are in-network

– Confirm the hospitals/facilities you prefer are covered the way you expect

Check #2: Prescriptions + pharmacy

– Confirm your medications are covered

– Confirm the best pharmacy option for that plan

Check #3: Total cost (not just premium)

Compare:

– specialist copays

– imaging and outpatient costs

– hospital cost-sharing

– maximum out-of-pocket

Thinking of returning to Original Medicare? Read this first

If you drop Medicare Advantage and return to Original Medicare, you might consider a Medigap (Supplement) plan to help with out-of-pocket costs.

Important note: depending on your situation and state rules, enrolling in Medigap (Supplement) outside certain windows can involve medical underwriting unless you qualify for specific guaranteed-issue rights.

That doesn’t mean it’s a bad option—it just means you want to understand the rules before making changes.

Quick checklist: what to have ready before changing plans

To make this quick and accurate, have:

– Your ZIP code

– Your doctors (PCP + specialists)

– Your prescriptions (name + dosage)

– Your preferred pharmacy

– The plan you’re currently enrolled in
