COBRA Is Not Creditable for Medicare Part B: The 2026 Trap Orlando Retirees Miss

Quick Answer: COBRA does not count as "coverage based on current employment" for Medicare. If you are 65 or older when you leave your job, your 8-month Special Enrollment Period for Medicare Part B starts when your employment ends — not when your COBRA coverage ends. Ride COBRA past that window and you can face a late-enrollment penalty of 10% for each full 12-month period you delayed, added to the 2026 standard Part B premium of $202.90 every month, for life — plus a gap with no Part B at all.

This is one of the most expensive misunderstandings we see in Central Florida, and it usually happens to careful people. They did the responsible thing: they kept coverage after leaving work instead of going bare. The problem is that Medicare's enrollment rules and COBRA's continuation rules were written by different laws, and they do not talk to each other.

Why COBRA feels safe — and why it isn't

COBRA lets you keep your former employer's group plan for up to 18 months (sometimes longer) after you stop working. Same network, same benefits, same ID card. If you retire at 65 or 66 from an Orlando employer, it is completely natural to think: "I have 18 months of coverage — I'll deal with Medicare when this runs out."

Here is what the rules actually say:

• Your Part B Special Enrollment Period lasts 8 months, and it begins the month after your employment ends or your active employer coverage ends — whichever comes first.
• COBRA is legally continuation coverage, not active employment coverage. The day you switch from employee to COBRA, your 8-month clock is already running.
• COBRA typically lasts 18 months. Your window lasts 8. If you wait for COBRA to run out, you are roughly 10 months too late.

What being late actually costs

If you miss the 8-month window, two things happen:

Consequence	What it means in 2026
General Enrollment Period wait	You can only sign up January 1 – March 31, with coverage starting the month after you enroll — potentially months with no Part B
Late-enrollment penalty	10% of the standard premium for each full 12-month period you were late — added to the $202.90/mo standard 2026 premium
Penalty duration	For as long as you have Part B — it does not expire
Secondary-payer surprises	Once you are Medicare-eligible, many COBRA plans pay secondary to Medicare — they can reduce or deny claims as if Medicare had paid, even if you never enrolled

That last row deserves a closer look. Some COBRA plans, once you turn 65, quietly begin treating Medicare as the primary payer. If you never enrolled in Part B, there is no primary payer — and you can be left with the share Medicare "would have paid" at a hospital system like AdventHealth or Orlando Health. People discover this after a surgery, not before.

Who this trap catches most often in Central Florida

• Retirees at 65–68 leaving a large employer and taking the COBRA packet HR hands them, assuming HR would have flagged any Medicare issue. (HR administers COBRA; Medicare enrollment is not their job.)
• Spouses who were covered under the worker's plan. The spouse's 8-month window runs on the same employment clock.
• People laid off before they planned to retire, who take COBRA while job hunting and cross their 8-month line mid-search.

What to do instead

1. If you are 65+ and leaving employment: treat the last day of work as the start of your 8-month Part B clock, regardless of any COBRA paperwork. Most people in this situation enroll in Part B effective the month after employment ends so there is no gap.
2. COBRA can still make sense for a short bridge — for example, to finish a treatment year with a deductible already met, or to cover a spouse under 65. Using COBRA is fine. Using it instead of enrolling in Part B is the trap.
3. Already on COBRA and 65+? Count months since your employment ended. If you are inside 8 months, enroll now. If you are past it, talk to a licensed agent about the General Enrollment Period and whether any exception applies to your situation — some limited exceptional-circumstance SEPs exist, and the earlier you address it the better.
4. Drug coverage is a separate clock. COBRA drug coverage can be creditable for Part D if the plan says so in writing — that is a different test from Part B. Keep the creditable-coverage notices your plan mails you.

The Orange County angle

Orange County has one of Florida's largest populations of workers who retire from hospitality, healthcare, and aerospace employers with strong group plans — exactly the plans that make COBRA look attractive. If you are retiring in Orlando, Winter Park, or Altamonte Springs (32714), the safest sequence is: pick your Medicare path first, then decide whether a short COBRA bridge adds anything.

Frequently Asked Questions

Does COBRA count as creditable coverage for anything? For Part B special enrollment purposes, no — only coverage from current employment counts. For Part D (drug coverage), COBRA can be creditable if the plan certifies its drug benefit is as good as Medicare's; the plan must tell you in writing each year.

I'm under 65 on COBRA. Does any of this apply to me? The 8-month rule matters once you are Medicare-eligible. If you will turn 65 while on COBRA, your Initial Enrollment Period around your 65th birthday is your enrollment window — do not let COBRA carry you past it.

My COBRA is cheaper than Part B plus a Medigap plan. Can't I just keep it? You can keep COBRA — but enrolling in Part B on time is what protects you from the lifetime penalty and the secondary-payer problem. Compare total costs with a licensed agent before assuming COBRA alone is the cheaper path; the math changes completely once a penalty attaches.
