The numbers that matter
Your action plan
Here is the order I want you to follow if you are on COBRA and turning 65. Do not skip steps. Do not assume COBRA "counts." It does not.
-
Confirm your Initial Enrollment Period dates
Your Medicare Initial Enrollment Period is a 7-month window: the 3 months before the month you turn 65, the month you turn 65, and the 3 months after. COBRA does not change this window. Look up your dates today at SSA.gov/medicare or call SSA at 1-800-772-1213. Write the dates on paper.

-
Enroll in Medicare Part A and Part B during your IEP
Even if you have COBRA, enroll in Part A and Part B during your Initial Enrollment Period. You can enroll online at SSA.gov/medicare/sign-up. Two clocks: COBRA's clock keeps running, but Medicare's IEP closes. Miss the IEP and you owe a 10% Part B Late Enrollment Penalty for every full 12 months you should have had Part B — for life.
Time: 20 minutes Cost: Part A free for most; Part B is $202.90/month in 2026 Sign up for Medicare
-
Compare COBRA vs. Medigap + Part D before you decide what to drop
COBRA is 102% of the full premium. That is usually more than Medicare Part B + a Medigap plan + a Part D plan combined. Get a side-by-side comparison so you are not paying twice. Free plan comparison from licensed Medicare advisors at Chapter — call 1-855-900-2427 and tell them Dr. Ed sent you.

Hang up on Medicare cold-callers — always
If someone calls you to sell you a Medicare plan, hang up. Cold-call Medicare solicitation is prohibited under CMS marketing rules. No legitimate Medicare advisor will cold-call you about a plan. If you want help, you call them — not the other way around. Call SHIP free at 1-877-839-2675 or Chapter at 1-855-900-2427.

Dr. Ed explains the COBRA trap
A short walkthrough of why COBRA does not count as creditable employer coverage for Medicare and how to avoid the Part B Late Enrollment Penalty. Video coming soon — bookmark this page.
Which situation sounds like yours?
Pick the situation that sounds most like yours. Different clocks for different people — but the rule about COBRA never changes.
I'm 65 and on COBRA — do I need to sign up for Medicare?Yes. COBRA does not delay Medicare.
Yes. Sign up for Medicare during your Initial Enrollment Period — the 7-month window around your 65th birthday. Do not wait for COBRA to run out.
COBRA is NOT considered current employer coverage under Medicare's rules. The Special Enrollment Period that lets some people delay Medicare past 65 only applies to active employer coverage tied to current employment — yours or a spouse's. Once employment ends, the clock starts, and COBRA does not stop it.
20 years at SSA taught me: every month you delay Part B past your IEP adds to a permanent penalty. Sign up on time and decide later whether to drop COBRA.
I'm retiring at 64 and taking COBRA — when does my Medicare SEP start?When the job ends — not when COBRA ends.
Your 8-month Special Enrollment Period starts the month after your active employment ends OR your group coverage ends — whichever comes first. COBRA does NOT extend that 8-month clock.
So if you retire at 64 and start 18 months of COBRA, your SEP started at retirement. Eight months later, the SEP closes. The remaining 10 months of COBRA do not extend Medicare protection.
If you turn 65 during those 18 months of COBRA, your Initial Enrollment Period applies instead — the IEP is tied to your 65th birthday, not to employment. Use whichever window opens first and do not let either close on you.
My spouse is on COBRA and turned 65 — what now?Same rules — Medicare on time, COBRA secondary.
When your spouse turns 65, the same rules apply. They need to enroll in Medicare during their own Initial Enrollment Period. COBRA does not exempt them.
Family COBRA can extend up to 36 months for a spouse if the qualifying event was the employee becoming Medicare-eligible — useful for a younger spouse who needs bridge coverage. But once that spouse hits 65, Medicare becomes their primary coverage and COBRA becomes secondary, if it pays at all.
Many plans terminate COBRA when an enrollee becomes Medicare-eligible. Read the COBRA notice carefully and ask the plan administrator in writing.
Does COBRA prescription coverage count for Part D?Maybe. Look for the Notice of Creditable Coverage.
COBRA prescription drug coverage may or may not be "creditable" for Part D Late Enrollment Penalty purposes. Your plan must send you a Notice of Creditable Coverage every year — typically before October 15.
If the notice says your COBRA Rx is creditable, you can delay Part D enrollment without a penalty. If it says non-creditable, you need to enroll in Part D on time or owe a Part D LEP for life: roughly 1% per month of delay times the national base beneficiary premium.
Keep the notice. Take a photo. SSA and Part D plans will ask for it.
I missed Medicare enrollment thinking COBRA was enoughYou can fix it — but the penalty may stick.
First: take a breath. You can still enroll. Call SSA at 1-800-772-1213 and ask about the General Enrollment Period (January through March, with coverage starting the month after enrollment under current rules) or any equitable relief that may apply.
The hard truth: most people in this situation owe a Part B Late Enrollment Penalty — 10% added to the standard premium for every full 12 months you should have been enrolled and weren't. The penalty is permanent.
In rare cases, equitable relief is granted if SSA, CMS, or an employer gave you wrong information in writing. Bring documentation. Bring patience. Get help from SHIP or a Medicare attorney.
I have COBRA and Medicare — do I drop COBRA?Usually yes. Check Medigap, Part D, and any spouse coverage first.
When you have both, Medicare is primary and COBRA is secondary. Many providers will deny COBRA claims expecting Medicare to have paid first. You are often paying COBRA's 102% premium for very little benefit on top of what Medicare already covers.
Most people are better off dropping COBRA and picking up Medigap (Plan G or Plan N are popular) plus a stand-alone Part D plan, or a Medicare Advantage plan. Total cost is usually well below COBRA.
Reasons to keep COBRA: a younger spouse on the COBRA policy still needs coverage, or COBRA covers something Medicare and Medigap do not (rare).
I'm helping a parent who's on COBRA at 65Bystander walkthrough — same rules, your eyes on the dates.
If you are helping a parent navigate this, you are doing them a real service. Same rules apply: COBRA does NOT count as creditable employer coverage for Medicare. Your parent needs to enroll in Medicare during their Initial Enrollment Period.
Get a paper copy of: their Medicare card or pending application, their COBRA notice with the end date, the Notice of Creditable Coverage for Part D, and any Social Security correspondence. Make a one-page timeline with three dates: IEP start, IEP end, COBRA end.

My situation is different from theseThat's normal. Here's how to get a real answer.
COBRA and Medicare touch a lot of edge cases: disability, end-stage renal disease, divorce, military retirees with TRICARE, federal employees with FEHB, and more. The rule that COBRA is not creditable employer coverage holds, but the timelines and penalty math can shift.

Questions I get all the time
Can I keep COBRA after I turn 65?
Yes, you can keep COBRA after 65, but you should not rely on it instead of Medicare. COBRA does NOT count as creditable employer coverage for Medicare's Special Enrollment Period. Enroll in Medicare during your Initial Enrollment Period (the 7-month window around 65) or you will owe a permanent Part B Late Enrollment Penalty.
Does COBRA count as creditable employer coverage for Medicare?
No. Under 42 CFR 407.20 and SSA POMS HI 00805.275, the Medicare Special Enrollment Period is only available to people with current employer-based coverage tied to active employment — yours or a spouse's. COBRA is post-employment continuation coverage and does not qualify. This is the single most common Medicare misunderstanding I saw in 20 years at SSA.
When does my 8-month Special Enrollment Period start?
The 8-month SEP starts the month after your group health coverage ends OR the month after active employment ends — whichever happens first. COBRA does not delay the start. So if you retire at 64 and take 18 months of COBRA, your SEP started at retirement and ends 8 months later, long before COBRA ends.
Should I keep COBRA when I have Medicare?
Usually no. Medicare becomes primary at 65 and COBRA becomes secondary. Most people are better off enrolling in Medicare and adding Medigap plus a stand-alone Part D plan — the total cost is usually less than COBRA's 102% premium. Reasons to keep COBRA: a younger spouse still needs coverage, or COBRA covers something Medicare doesn't.
What about my spouse's COBRA after I retire?
If you retire and become Medicare-eligible, family members on the employer plan can elect COBRA for up to 36 months — a longer window than the standard 18 months because your Medicare entitlement is the qualifying event for them. Once your spouse turns 65, the same rules apply: enroll in Medicare on time, COBRA becomes secondary.
Does COBRA prescription drug coverage count for Part D?
Sometimes. Your COBRA plan must send you a Notice of Creditable Coverage every year (usually before October 15). If your COBRA Rx is creditable, you can delay Part D without a Late Enrollment Penalty. If non-creditable, you need to enroll in Part D on time. Save the notice — SSA and Part D plans will ask for it.
What's the COBRA premium vs. Medicare premium?
COBRA can charge up to 102% of the total premium (employer + employee shares plus a 2% admin fee). Medicare Part B in 2026 is $202.90/month for most people. Adding Medigap and Part D usually still totals well below typical COBRA premiums. Get a side-by-side comparison before you decide.
What happens if I missed Medicare enrollment because of COBRA?
You'll likely owe a Part B Late Enrollment Penalty: 10% added to your standard Part B premium for every full 12 months you should have been enrolled but weren't. The penalty is permanent — you pay it for as long as you have Part B. In rare cases, SSA grants equitable relief if you got incorrect information in writing from a federal source. Call SSA at 1-800-772-1213 and document everything.
Is Medicare primary or secondary when I have COBRA?
Medicare is primary; COBRA is secondary. This is set by federal Medicare Secondary Payer rules. Providers will often bill Medicare first and may deny COBRA claims that should have been submitted to Medicare. If you are paying COBRA premiums while Medicare is primary, you are paying for very little additional benefit. That is the main reason most people drop COBRA once Medicare starts.
Where can I get free help deciding?

Chapter is a licensed Medicare brokerage that offers free plan comparison from licensed Medicare advisors — call 1-855-900-2427 and tell them Dr. Ed sent you.
