Working past 65: three rulebooks, one playbook
Working past 65 with VA Healthcare, TRICARE, or CHAMPVA changes the Medicare playbook: employer coverage from a 20+ employee company is the one thing that legitimately delays Part B, VA care alone never is, HSA contributions and Medicare can't coexist, and an 8-month Special Enrollment Period catches you when the job ends.
The five questions every working veteran hits at 65
Roughly one in five Americans 65–74 still works — and veterans in that group juggle a third system on top of employer insurance and Medicare. These guides take the questions in the order they actually arrive:
Can I delay Medicare?
The 20-employee rule, why VA care doesn't substitute, and how the three coverages actually stack.
What about my HSA?
The contribution cutoff, the six-month Part A backdating trap, and the year-of-enrollment proration math.
How do I enroll later?
The 8-month Special Enrollment Period, forms CMS-40B and CMS-L564, and the timing that avoids gaps.
Is my drug coverage creditable?
Layering employer, VA, TFL, and CHAMPVA drug benefits — and the annual notice that answers the question.
What about my spouse?
Whose employer plan covers whom, age-gap timing, and the TFL/CHAMPVA wrinkles.
When should I make the switch?
Sequencing the retirement date, Part B effective date, Medigap window, and wraparound start.
The rules of the road, compressed
| If your employer coverage is… | Delaying Part B is… | Why |
|---|---|---|
| Current employment, 20+ employees (yours or your spouse's) | Safe | The plan pays primary; an 8-month SEP opens when work ends |
| Current employment, under 20 employees | Risky | Medicare is meant to pay primary — skipping B leaves a coverage hole and penalty exposure |
| COBRA or retiree coverage | Not safe | Neither counts as current employment — the SEP clock runs anyway |
| VA Healthcare alone | Not safe | Not creditable for Part B — the rule this site exists to repeat |
Drug coverage runs on a separate, friendlier track: VA, TFL, and CHAMPVA are all creditable for Part D regardless of work status, and most large-employer drug plans are too (the plan must tell you each fall).
Your wraparound waits for Part B. Delay B legitimately behind a big-employer plan and TFL or CHAMPVA simply sits dormant until B begins — the employer plan pays primary in the meantime, with TRICARE/CHAMPVA rules for active coverage applying. The retirement-timing guide sequences the handoff.
Working past 65 stacks three rulebooks. An agent who reads all three can confirm your exact delay rights and deadlines in one conversation — before anything is irreversible.
