Direct answer: Ask whether your coverage is a group health plan based on current employment for you or a spouse. Medicare.gov says you may wait to sign up for Part B until you or your spouse stop working, or until that insurance ends if that happens first, without a Part B late enrollment penalty. You then have an 8-month Special Enrollment Period. COBRA and retiree coverage do not count as current-employment coverage for that delay.
Should I take Part A while I keep working?
Medicare.gov working past 65 says if you do not pay a premium for Part A, you can choose to sign up at 65 or later. Some employer plans still want you to enroll in Part A. Ask the benefits administrator in writing. Part A enrollment can affect Health Savings Account contributions; see how Medicare works with an HSA.
When can Part B wait?
If you or your spouse have health insurance from a job and you are still working, Medicare.gov says you may wait on Part B without a late enrollment penalty, then use an 8-month Special Enrollment Period after employment or that insurance ends, whichever happens first. Confirm the facts with Social Security and the employer. This is the same decision covered on Working past 65 in Lakeland; this article is the enrollment-timing question, that page is the local checklist.
If you are self-employed or have coverage that is not offered to all employees at the company, Medicare.gov says to ask whether it is employer group health plan coverage as defined by the IRS. If it is not, sign up when you first become eligible, typically at 65.
Why COBRA is not a reason to delay Part B
Medicare.gov states that the Special Enrollment Period starts when you stop working or lose the current-employment insurance, even if you choose COBRA. Do not wait for COBRA to run out to sign up for Part B. See whether you need Part B with employer insurance and late enrollment penalties.
Does Medicare Open Enrollment replace this decision?
No. Annual Enrollment (October 15 through December 7) is for people who already have Medicare and want to make eligible Advantage or Part D changes. It does not replace the Initial Enrollment Period or the current-employment Special Enrollment Period. Medigap follows separate rules and is not an annual AEP product change. See when you can switch Medicare plans in Florida.
What if my spouse is the employee and I am turning 65?
Medicare.gov describes current-employment coverage through your job or your spouse's job. The Special Enrollment Period is still limited. Confirm whether the spouse's plan covers you as a dependent after 65 and whether the employer requires your Part B. Get that in writing.
If the employer is a small group, additional Medicare secondary-payer rules can apply. Those rules are not the same for every employer size. The administrator and Medicare.gov, not an informal office rumor, are the sources.
Drug coverage can be creditable even when you delay Part B. Keep the annual notice. A licensed Florida health agent can review Advantage or Medigap later; the first job is the Part A and Part B clock.
How do I document creditable drug coverage?
Ask the employer or union for the annual creditable coverage notice for the prescription benefit. Keep it with your Social Security file. If the notice says the coverage is not creditable, delaying Part D can create a late enrollment penalty. Medicare.gov explains the 63-day gap test on the penalty page.
When employment ends, the Part B Special Enrollment Period and the Part D clock are not identical. Put both on a calendar. See late enrollment penalties.

What to do next
Ask human resources whether the plan is current-employment group coverage, whether they require Part A or Part B at 65, and whether your drug coverage is creditable. Then decide with Social Security timing in view. David Huff, a licensed Florida health agent, can review Lakeland employer-plus-Medicare coordination by appointment.
