I’m retiring and losing my health insurance through work. When do I need to enroll in Medicare in Louisiana?

Question

Caroline Johnson · Accepted Answer

Employer with 20+ employees: You get an 8-month Special Enrollment Period starting the month after employment or coverage ends, whichever comes first. No late penalty during this window.

Employer with fewer than 20 employees: Medicare is already primary at 65, so enroll right at 65 rather than waiting for retirement — the group plan likely won't cover much without Medicare in place.

Best timing: File for Part B a month or two before coverage ends, so Medicare starts the day after, with no gap. You'll need Form CMS-L564 (employer completes) plus CMS-40B, filed with Social Security.

Watch for: COBRA doesn't count as coverage that delays Medicare — enrolling in COBRA instead is a common costly mistake.

Jeremy Harkins · Answer

If you are 65 or older and retiring from a job that provides your health insurance, I recommend starting the Medicare transition **12 weeks before your employer coverage ends.**

**12 weeks before:** Confirm the exact date your employer medical and prescription coverage ends.

If you already have Part A and delayed Part B, submit:

* **CMS-40B** — Application for Medicare Part B
* **CMS-L564** — Employer verification showing you had coverage through current employment

If you delayed both Part A and Part B, apply for both instead of using the Part B-only process.

Also determine the Medicare effective date you need. This is especially important if your employer coverage ends in the middle of a month, because Medicare Advantage and Part D plans generally begin on the **first of the month**.

**10 weeks before:** Confirm Social Security received everything and that no additional information or employer verification is needed.

**8 weeks before:** Confirm your **Medicare Beneficiary Identifier (MBI)** and your Part A and Part B effective dates. If you already had Part A, you should already have an MBI; make sure Part B is showing with the correct effective date.

Once the MBI and Medicare dates are confirmed, submit the coverage that will replace your employer plan — either a **Medicare Advantage plan**, or a **Medicare Supplement and Part D prescription plan**.

**6 weeks before:** Confirm that the new coverage has been accepted and that all effective dates line up correctly. At this point, the Medicare transition should be fully in place.

The goal is to have everything completed **at least six weeks before your employer coverage ends**.

This can sometimes be done in less time. The 12-week timeline is recommended to allow for Social Security processing, employer verification, obtaining or confirming the MBI, plan enrollment, and time to correct a problem without rushing.

If you’re retiring in Louisiana and losing health coverage from your current employer, you may qualify for a Special Enrollment Period to sign up for Medicare Part B without waiting for the General Enrollment Period. In most cases, you can enroll while you’re still covered by the employer plan or within eight months after your employment or coverage ends, whichever happens first. As a local licensed agent serving Louisiana, I can help you plan your Medicare start date and review your coverage options so you can avoid an unexpected gap in coverage.

You will have a two-month period in which to enroll in Medicare based on when your creditable coverage at work comes to an end. You then also will have a Special Enrollment Period in which to enroll in a Medicare Advantage plan or Medigap insurance (together with a Part D plan). You will need to submit a form signed by both yourself and your employer which attests to the fact that you have had "creditable" coverage since turning 65.

Jonathan Potter · Answer

You can enroll in Medicare when you are 65 and older. To do this you get online at ssa.gov and make a login. Once in you can go down to the medicare section and choose to start your medicare from there. You can also contact Social Security online or call and set up an appointment to go in and get signed up from there. If you delay enrollment because your work covered your insurance and you have already turned 65 you have to fill out a form and let your HR department prove you had coverage from the time you were 65 till now.

You have up to 8 months to sign up after you stop working, if you have creditable insurance and drug coverage ask for a letter of proof from your employer so you do not have any penalties.

Bryan Monteagudo · Answer

You should enroll as soon as possible if retiring in the next 3 month. You will need to be 65 year s or older to apply for Medicare.
