If you live in Louisiana and you have been searching for how and when to change your Medicare Advantage or Medigap plan, you have probably found confusing answers, because the rules depend on which type of plan you have. Here is a clear Louisiana-specific guide that separates the two, with the federal windows that apply everywhere and what to check for Louisiana in particular.
The quick answer for Louisiana
- Medicare Advantage: you can generally change during the Annual Enrollment Period (October 15 to December 7), during the Medicare Advantage Open Enrollment Period (January 1 to March 31) if you are already in an Advantage plan, or during a Special Enrollment Period if you qualify. These windows are set by Medicare, so they are the same in Louisiana as in every state.
- Medigap: there is no annual deadline, but whether you can switch without health questions depends on protections that include some state rules. See below for what we found for Louisiana.
Medicare Advantage changes in Louisiana
- Annual Enrollment Period (Oct 15 – Dec 7). Change plans for the following January 1. See our Annual Enrollment guide.
- Medicare Advantage Open Enrollment (Jan 1 – Mar 31). If you are already in an Advantage plan, you get one change. Read the full guide.
- Special Enrollment Periods. Triggered by moving to a new area, losing other coverage, your plan ending, or qualifying for Extra Help or Medicaid, among others. See when you can switch plans.
Medigap changes in Louisiana
Louisiana is reported in 2026 sources as having a Medigap birthday rule. Reports describe a window of about 63 days following your birthday to switch to a plan with equal or lesser benefits without health questions, with the choice generally limited to your current insurer or its affiliate, though one guide describes a different window, so the details vary by source. Confirm the current window and rules with the Louisiana Department of Insurance before relying on it.
Regardless of state, you generally have protection in your six-month Medigap Open Enrollment Period and in certain federal guaranteed-issue situations. Our national guide, when can I change my Medigap plan, explains each one.

Get my plan reviewWhat to think about in Louisiana
Louisiana is organized into parishes, not counties, and Medicare plan availability is set by service area, so it can differ from one parish to the next. Residents in the New Orleans and Baton Rouge areas may have more plan choices than those in smaller parishes. Check that the hospitals and doctors you use, including those you reach after storms or travel, are in your plan's network. We serve people in and around New Orleans, Baton Rouge, Lafayette, Shreveport and Lake Charles, and we handle everything by phone.
Common situations people ask about
- "My doctor left my plan's network." You may qualify for a Special Enrollment Period in some cases, and you can compare plans at the next window. See what to do when a plan drops your doctor.
- "My premium or drug costs went up." Review your Annual Notice of Change and compare during the next open window.
- "I moved within Louisiana." A move to a different county can change which plans you can choose, and may open a Special Enrollment Period.
- "I want to move from Advantage back to Original Medicare." Check your Medigap options before you cancel. Read leaving Medicare Advantage.
- "I have both Medicare and Medicaid." You may have more frequent change opportunities. See Medicaid and dual-eligible options.
- "My parish has fewer plan options." Plan availability is set by service area, so compare plans at your exact address and ask about nearby parishes' hospitals.
A checklist before you change anything in Louisiana
- Identify which window you are in (AEP, MA-OEP, SEP, or Medigap rules).
- List your doctors, hospitals, pharmacies, and medications.
- Check each against the plan you are considering at your Louisiana address.
- If it is Medigap, find out whether underwriting applies and apply before you cancel.
- Confirm the effective date in writing.
