What is your employment and healthcare status right now?
The correct Medicare decision depends entirely on the size of your company and the structure of your group benefits:
Turning 65 While Actively Employed
Determining whether to enroll in Part A only, delay Part B, or transition completely off employer coverage to private Medicare.
Employer Has Under 20 Employees
Medicare automatically becomes the primary payer at 65. Failing to enroll in Part B can result in catastrophic unpaid medical claims.
Employer Has 20+ Employees
Your group plan remains primary payer. You can generally delay Part B penalty-free as long as you have active-employment coverage.
Contributing to an HSA Account
Enrolling in Part A creates up to 6 months of retroactive coverage, triggering IRS excise tax penalties on HSA contributions made past 65.
Retiring Within 6–12 Months
Preparing CMS Form L564 (Employer Verification) and CMS Form 40B for a seamless transition without a single day of coverage lapse.
Offered COBRA or Retiree Health
COBRA and retiree plans do NOT count as active-employment coverage. The 8-month Part B SEP clock starts when active work ends.
Working for a company with fewer than 20 employees or leaving your job this month?
At companies with under 20 employees, Medicare is the primary payer at 65. If you fail to enroll in Part B, your group plan can deny medical claims. Call Sarah directly to audit your employer status and prevent uncovered medical emergencies.
Safe harbor rules for working past 65.
If your active employment situation meets these federal statutory standards, you can avoid Part B premiums without penalty:
If the employer employs 20 or more staff, the group health plan pays primary to Medicare. You can delay Part B until you retire without penalty.
Coverage under your spouse’s active employer plan (20+ employees) provides the exact same penalty-free Part B delay rights as your own job.
As long as your employer provides an annual notice verifying your drug plan is creditable, you are exempt from Part D late enrollment penalties.
Federal law gives you an 8-month window after employment ends to sign up for Part B without paying a permanent 10% annual penalty.
Dangerous Medicare timing traps past 65.
Mistakes made while working past 65 can result in severe financial penalties and rejected medical claims:
If your company has fewer than 20 employees, Medicare is the primary payer. Your group insurer will not pay for services Medicare should have covered.
COBRA is continuation coverage, NOT active employment coverage. The 8-month SEP begins when active work ends. Waiting until COBRA expires causes permanent penalties.
Retiree plans coordinate with Medicare and expect you to have Part A and Part B active. They will not pay primary benefits if you delay enrollment.
Applying for Part A after 65 triggers up to 6 months of retroactive coverage. Contributing to an HSA during that retroactive window creates an IRS tax penalty.
How we coordinate your working-past-65 transition
A structured 5-stage roadmap ensuring your employer benefits, HSA contributions, and Part B enrollment execute with zero gaps or penalties.
Audit
Verify exact employer headcount (20+ vs. under 20), confirm active employment status, and check annual written creditable drug coverage notices.
Benchmark
Compare your employer monthly payroll deductions, deductible, and out-of-pocket maximum against private Medicare Advantage and Medigap options.
Timing
Structure your exact timeline to halt HSA contributions 6 months prior to Part A application and protect your 8-month Special Enrollment Period.
Coordinate
Assist with Social Security paperwork (CMS-L564 and CMS-40B), ensuring HR signs off properly so your Part B application is approved without delays.
Implement
Activate your chosen Medigap or Medicare Advantage policy on day one of retirement and provide ongoing annual AEP reviews every fall.
Retire on your terms with zero coverage disruption.

Frequently Asked Questions About Working Past 65
Clear answers on employer coordination, Part B delay rules, and Special Enrollment Periods.
Can I delay Part B if my spouse is still working?
Yes. If you are covered under a group health plan based on your spouse’s active employment at a company with 20 or more employees, you can generally delay Part B without a late enrollment penalty. COBRA or retiree coverage does not qualify.
Does COBRA give me eight months to enroll in Part B after COBRA ends?
No. Medicare and Social Security rules state that the 8-month Special Enrollment Period begins the month after active employment or group coverage ends—whichever happens first. Relying on COBRA past that 8-month window triggers permanent late penalties.
Should I enroll in Part A if I keep working and have an HSA?
If you wish to continue contributing to a Health Savings Account (HSA), you should generally delay Part A. Enrolling in Part A retroactively covers up to 6 months, disqualifying you from HSA contributions and creating potential IRS tax penalties.
What happens if my employer has fewer than 20 employees?
At companies with under 20 employees, Medicare is the primary payer. If you do not enroll in Part A and Part B at 65, your group health plan can deny claims for services Medicare would have covered, leaving you with catastrophic bills.
What forms do I need from HR when I retire after 65?
You will need Form CMS-L564 (Request for Employment Information) signed by your employer’s HR or benefits department, along with Form CMS-40B (Application for Part B). These verify creditable coverage and waive the Part B late penalty.
