Working Past 65 · Medicare Decision Guide · NC 2026

Still Working at 65? Here’s What You Actually Need.

One number decides everything: your employer’s headcount. 20 or more = you can delay Part B. Under 20 = enroll now or pay 10% per year permanently. Six NC situations mapped to exact actions.

“Every plan on the market was built with a weakness.”

Medicare salespeople won’t tell you which one you’re in. I will. Every plan — Medicare Advantage, Medigap, Part D — was designed with trade-offs. A $0 premium plan isn’t free. A plan with a big name on the card isn’t necessarily the best plan in your county. The weakness isn’t in the brochure. It shows up when you need the plan to actually work.

The One Question That Determines Everything

Quick Answer

Whether you need Medicare while still working comes down to a single test: how many employees does your employer have? If 20 or more — you have qualifying employer group health plan coverage and may delay Medicare Part B without penalty for as long as active employment continues. If fewer than 20 — Medicare is primary at age 65 regardless of how good your employer plan is. Delay Part B and you owe a permanent 10% per 12-month penalty. The quality of the plan does not matter. The size of the employer does. Call (828) 761-3326 to verify before you decide. NC License #10447418.

The 20-Employee Test — Which Side Are You On?

Count all employees at the company — not just your location, not just full-time. Part-time employees count toward the 20 threshold.

✓ 20 or More Employees

You May Delay Part B

  • Employer GHP is primary — Medicare would be secondary
  • Part B delay OK for as long as active employment continues
  • Enroll in Part A now — free with 40+ work quarters, acts as secondary payer
  • Part D delay OK if HR confirms drug coverage is creditable (get annual letter)
  • 8-month SEP opens the day employment or coverage ends — not COBRA end
  • 6-month Medigap guaranteed-issue OEP opens when Part B goes active
  • Need CMS-L564 from HR when you eventually enroll in Part B
✕ Fewer Than 20 Employees

Enroll in Part B Now

  • Medicare is primary at 65 regardless of employer plan quality
  • Employer plan pays secondary — calculates as if Medicare already paid
  • Delay Part B = permanent 10%/year penalty from IEP close date
  • Every 12 months of delay adds another 10% to your premium forever
  • Coverage quality does not matter — employer size is the only test
  • Enroll in Part A, Part B, and Part D during your 7-month IEP
  • Medigap OEP opens when Part B goes active — a one-time 6-month window in NC

“Are you actually sure you understand what you’re signing up for?”

Most people turning 65 get buried in Medicare mail, carrier calls, and TV ads — all saying the same thing. Nobody’s sitting down with you and walking through what your plan actually covers, what it doesn’t, and what it costs when something goes wrong. That’s the conversation that’s missing.

Six NC Working-Past-65 Situations — Exact Action for Each

Most NC residents approaching 65 while working fall into one of these six situations. Each has a specific action. Getting the wrong one costs you money permanently.

1
Situation
Your employer has 20 or more employees — you are covered under their group plan
Active employment · company-sponsored health plan · 20+ total employees companywide
✓ May Delay Part B

Part A: Enroll now. Premium-free with 40+ work quarters. Acts as secondary payer behind your employer plan — picks up hospital costs your employer plan doesn't cover. Delaying Part A makes sense only if you contribute to an HSA (see the HSA Trap section below).

Part B: Delay is OK. No penalty as long as active employer coverage from a 20+ employee employer continues. Do not delay past the 8-month SEP window after coverage ends.

Part D: Delay is OK if your employer plan includes creditable drug coverage. HR must provide an annual Creditable Coverage Notice confirming this — typically before October 15 each year. Keep that letter. You'll need to show no penalty applies when you eventually enroll in Part D.

When You Leave

8-month SEP starts the day employment or coverage ends — whichever is first. Bring CMS-L564 (completed by HR) to Social Security. Your Medigap 6-month guaranteed-issue OEP also opens when Part B goes active.

Cost Comparison

Many 20+ employee plans cost less than Medicare + Medigap + Part D. If employer covers you well, staying on employer insurance can save $200–$400/month. Run both scenarios. Call (828) 761-3326.

2
Situation
Your employer has fewer than 20 employees
Small employer · fewer than 20 total employees companywide · any coverage type
⚠ Must Enroll in Part B at 65

The rule: When an employer has fewer than 20 employees, Medicare becomes the primary payer at age 65. Your employer plan becomes secondary. This means your employer plan calculates benefits as if Medicare had already paid its portion — even if you haven't enrolled in Medicare. Since Medicare hasn't paid anything (because you're not enrolled), your employer plan pays very little or nothing on claims you assumed were covered.

The penalty: Every 12 months past your IEP without Part B adds a permanent 10% surcharge. Three years late = 30% = $55.50/month extra in 2026, every month for life. The dollar amount grows each year as CMS raises the standard premium.

How to verify employer size: Count all employees at the company — not just your location. Part-time employees count toward the threshold. If your employer fluctuates around 20, ask HR directly which Medicare rules apply. When in doubt: enroll in Part B. Call (828) 761-3326. NC License #10447418.

3
Situation
You are covered under your spouse’s employer plan
Spouse is actively employed · you are a dependent on their group health plan
✓ May Delay Part B — if spouse’s employer has 20+

The 20-employee rule applies to the employer of the person who is actively working — in this case, your spouse. If your spouse’s employer has 20 or more employees, you may delay Part B without penalty even though you are not actively employed there.

If your spouse’s employer has fewer than 20 employees, Medicare becomes your primary insurer at 65 regardless of your spouse’s active employment — and you must enroll in Part B.

When Spouse Retires

Your 8-month SEP opens the day your spouse’s employer coverage ends — not COBRA end. Bring CMS-L564 completed by your spouse’s HR. Your Medigap OEP opens when Part B goes active.

Key Risk

If your spouse leaves their employer before you turn 65, or changes to a smaller employer, the qualifying coverage may change mid-stream. Verify employer size annually. Call (828) 761-3326.

4
Situation
You are self-employed, a 1099 contractor, or a freelancer
Business owner · sole proprietor · LLC · any self-employment arrangement
⚠ Enroll in Medicare During IEP

Self-employment does not qualify as employer group health plan coverage for Medicare delay purposes. Individual health insurance plans — including ACA marketplace plans purchased on your own — are not qualifying coverage. There is no employer-size exception for self-employed individuals.

Enroll in Medicare Part A, Part B, and Part D during your 7-month Initial Enrollment Period.

ACA subsidy alert: If you currently receive ACA premium tax credits and enroll in any part of Medicare, you lose eligibility for those credits. Continuing to receive ACA subsidies after Medicare enrollment can trigger repayment at tax time. Coordinate your Medicare enrollment date carefully with your ACA plan cancellation date. Call (828) 761-3326. NC License #10447418.

5
Situation
You are currently on COBRA
Former employee · elected COBRA after leaving employer · still paying for continuation coverage
⚠ Enroll in Medicare — Do Not Wait for COBRA to Expire

COBRA is continuation coverage — not active employer group health plan coverage. It does not qualify you to delay Medicare Part B without penalty. The 8-month SEP clock started the day your active employer coverage ended — the same day COBRA began. If that SEP has already closed, you are in penalty territory.

COBRA drug coverage is also not guaranteed to be creditable for Part D purposes. Check your COBRA Creditable Coverage Notice before assuming you can delay Part D.

When you enroll in Medicare, COBRA typically terminates. Do not wait for the 18 months of COBRA to expire — the penalty clock does not pause during COBRA. Call (828) 761-3326 immediately if you are on COBRA and past 65. NC License #10447418.

6
Situation
You have retiree coverage from a former employer
Retired · receiving health benefits from former employer as a retiree benefit
⚠ Enroll in Medicare During IEP

Retiree coverage is not active employment. It does not qualify as an employer group health plan for Medicare delay purposes. Enroll in Medicare Part A, Part B, and Part D during your Initial Enrollment Period.

Critical retiree plan warning: Many retiree plans require you to enroll in Medicare Part B as a condition of maintaining retiree benefits. Refusing to enroll in Part B could void your retiree coverage entirely. Check with your former employer’s HR or benefits administrator before your IEP closes. Call (828) 761-3326. NC License #10447418.

Coordination

Medicare pays primary. Retiree plan pays secondary. Some retiree plans wrap around Medicare and cover cost-sharing Medicare does not pay — similar to Medigap. Confirm your retiree plan’s coordination rules before enrolling.

Drug Coverage

Some retiree plans include creditable drug coverage. Get a Creditable Coverage Notice from HR before assuming you can delay Part D. If retiree drug coverage is non-creditable, enroll in Part D during your IEP.

⚠ The HSA Trap — Affects High-Deductible Plan Users

Enrolling in Part A Ends Your Ability to Contribute to an HSA

If you contribute to a Health Savings Account (HSA) through a High Deductible Health Plan (HDHP), there is a critical timing issue you must understand before enrolling in Medicare Part A — even if you plan to delay Part B.

Enrolling in Part A disqualifies you from making HSA contributions for any month you are enrolled in Medicare. Part A can be retroactive up to 6 months when you apply. If you apply for Part A at 65½ and CMS makes it retroactive to your 65th birthday, any HSA contributions made in those 6 months become “excess contributions” — subject to a 6% IRS excise tax and potential income tax.

The fix if you want to keep contributing to your HSA:

→ Stop HSA contributions 6 months before you plan to enroll in Part A

→ Or delay Part A enrollment entirely until you stop contributing to your HSA

→ This is one of the few situations where delaying Part A makes financial sense

→ Coordinate the timing carefully — call (828) 761-3326 for HSA-specific guidance. NC License #10447418.

“Do you know what your plan’s weakness is?”

Every plan on the market was built with one. The $0 premium, the low monthly cost — those numbers look great until something goes wrong. Most people never find the weakness in their plan. They find it when they need the plan to work.

What Is Form CMS-L564 and Why Does It Matter?

When you leave qualifying employer coverage and apply for Medicare Part B under an 8-month Special Enrollment Period, Social Security requires Form CMS-L564 — the Request for Employment Information form — as documentation that you had qualifying employer group health plan coverage.

Your employer’s HR department completes Section B of the form, confirming the dates of your group health plan coverage and employment. Without it, Social Security may not grant the SEP and may instead apply the late enrollment penalty as if you had no qualifying coverage.

📋 Get CMS-L564 From HR Before You Leave — Not After

Request Form CMS-L564 from your employer’s HR department as soon as you decide to retire, or immediately when coverage ends. HR departments have no obligation to complete the form quickly — and some take weeks. If you wait until after your employment ends to request it, delays in getting the completed form can push you past the 8-month SEP window. Get the form early. Keep a copy. Bring it to Social Security when you apply for Part B. Call (828) 761-3326 for help navigating the SEP application process. NC License #10447418.

💡 Robert Simm — NC License #10447418

The call I dread most: “I worked for a small firm for 20 years. Great coverage. My HR said I didn’t need Medicare yet. I just turned 68 and now I’m on Social Security — they’re taking a 30% penalty out of my check.” The HR person was wrong. The employer had 15 employees. Medicare was primary from age 65. That 30% penalty — $55.50/month at 2026 rates — is now permanent. It grows in dollar terms every year. Over 15 years of retirement: nearly $10,000 in excess premiums from one piece of bad information.

I spend 10 minutes on the phone verifying employer size, checking HSA status, and mapping the exact IEP timeline before any client makes a delay decision. That call is free. The penalty is not. (828) 761-3326. NC License #10447418.

“Here’s what Medicare Advantage actually costs when something goes wrong.”

Your PCP visit is $0. Your blood work is $0. Then you have a cardiac event. A cancer diagnosis. A surgery that requires a specialist who isn’t in your network. Now you’re looking at an $8,300 out-of-pocket maximum, prior authorization delays, and a facility bill you didn’t expect. The $0 premium plan isn’t free — you’ll find that out the hard way, or you won’t.

Working Past 65 — NC Checklist

📋

Verify Employer Size First

Count all employees companywide — not just your location. Part-time counts. If your employer is near 20, confirm with HR in writing which Medicare rules apply. Do not guess. Call (828) 761-3326.

💰

Get Annual Creditable Coverage Notices

HR must send you a Creditable Coverage Notice before October 15 each year confirming your drug coverage qualifies for Part D delay. Keep every letter. If you ever lose them, request copies from HR.

📋

Request CMS-L564 Early

Get Form CMS-L564 completed by HR before your last day of employment. You’ll need it when you apply for Part B under SEP. HR delays can push you past the 8-month window.

⚙

Enroll in Medigap Same Month as Part B

Your 6-month NC guaranteed-issue Medigap OEP opens the day Part B goes active. NC has no birthday rule to reopen it later. Enroll in Medigap in the first month — do not wait to see how Medicare goes.

💸

HSA Users: Stop Contributions 6 Months Early

Stop HSA contributions 6 months before enrolling in Part A to avoid excess contribution penalties from Part A retroactivity. Coordinate your enrollment date with your last HSA contribution month.

“What happens if you’re on the wrong plan when something serious comes up?”

Nothing — until it does. A diagnosis. A surgery. A specialist that isn’t covered. That’s when the affordable plan starts costing you thousands. And by the time you find out, the enrollment window is usually closed. That’s not a hypothetical — that’s what happens to people every year in North Carolina.

Frequently Asked Questions
Common questions about Medicare and working past 65 in North Carolina for 2026.
Do I need Medicare Part B if I still work and have employer insurance?

It depends on your employer’s size. 20 or more employees: you may delay Part B without penalty for as long as active employment continues. Fewer than 20 employees: Medicare is primary at 65 — delay Part B and you owe a permanent 10% per 12-month penalty. The quality of your employer plan has no bearing on this. Only the headcount matters. Call (828) 761-3326 to verify. NC License #10447418.

Does COBRA count as creditable coverage to delay Medicare Part B?

No. COBRA is continuation coverage, not active employer group health plan coverage. The 8-month SEP clock starts when active employer coverage ends — the same day COBRA begins. Waiting for COBRA to expire results in a permanent Part B penalty. Enroll in Medicare within the 8-month SEP window. Call (828) 761-3326. NC License #10447418.

Can I delay Medicare Part B if I am covered under my spouse’s employer plan?

Yes, if your spouse’s employer has 20 or more employees and you are actively covered under their group plan. The 20-employee rule applies to the employer of the person who is actively working. If your spouse’s employer has fewer than 20 employees, Medicare becomes your primary insurer at 65. When your spouse retires, your 8-month SEP begins immediately. Call (828) 761-3326. NC License #10447418.

What is the Medicare HSA trap for people still working at 65?

Enrolling in Part A — even Part A only — disqualifies you from making HSA contributions. Part A can be retroactive up to 6 months when you enroll. Contributions made during the retroactive period become excess and may trigger a 6% IRS excise tax. Fix: stop HSA contributions 6 months before enrolling in Part A, or delay Part A until you stop HSA contributions. Call (828) 761-3326. NC License #10447418.

What is form CMS-L564 and when do I need it?

CMS-L564 is the Request for Employment Information form. Social Security requires it when you apply for Part B under a Special Enrollment Period to prove you had qualifying employer coverage. HR completes Section B. Without it, SSA may apply the late enrollment penalty. Request it from HR before your last day of employment. Call (828) 761-3326. NC License #10447418.

Does self-employment count as employer coverage to delay Medicare?

No. Self-employment, 1099 work, and freelance do not qualify as employer group health plan coverage. Individual health insurance plans including ACA marketplace plans are also not qualifying coverage. Enroll in Medicare Part A, Part B, and Part D during your Initial Enrollment Period. If you receive ACA premium tax credits, coordinate enrollment carefully to avoid subsidy repayment at tax time. Call (828) 761-3326. NC License #10447418.

“Every plan I’ve ever reviewed has a weakness.”
