Working after 65 creates several separate decisions: when employment ends, when job-based insurance ends, when Medicare begins and when health savings account contributions must stop. Put each date on its own line. A retirement application date alone cannot answer all four questions.
This worksheet extends the FEHB and Medicare Part B overview. It helps prepare an enrollment conversation; it does not establish an individual enrollment exception or recommend a Medicare plan.
Identify whose current employment supports coverage
Medicare describes an eight-month Part B special enrollment period after current employment or qualifying job-based coverage ends, whichever happens first. Retiree insurance and COBRA do not extend that employment-based period. Confirm that the actual coverage qualifies before relying on delayed enrollment. Ask about coverage based on a spouse's current employment separately.
FEHB and PSHB are different programs. Certain Medicare-eligible postal annuitants and family members must have Part B to retain PSHB unless an exception applies. Do not borrow a coworker's FEHB answer for a postal retirement decision.
Build the timeline before submitting forms
| Date or status | Record to obtain | Question to resolve |
|---|---|---|
| Medicare eligibility begins | Official eligibility information | Does age, disability or another basis determine this date? |
| Last day of current employment | Employer confirmation | Is this the employment supporting delayed Part B enrollment? |
| Job-based coverage ends | Benefits office statement | Does coverage end later than work, and which date starts the applicable clock? |
| Medicare application submitted | Submission receipt | Which Parts were requested and what documentation remains outstanding? |
| Medicare effective date | Enrollment confirmation | Does this match the coverage transition plan? |
| HSA contribution stop date | Payroll and tax review | Are employer and employee contributions both addressed? |
Use confirmed dates rather than a guessed first-of-the-month assumption. Add an owner and a follow-up date to unresolved rows. Keep the resulting worksheet in personal records; medical, payroll and Social Security documents do not belong in a website inquiry form.
Separate HSA contributions from spending existing savings
Medicare enrollment can affect HSA contribution eligibility even if an account remains open. Premium-free Part A can have retroactive coverage when enrollment occurs after initial eligibility. Medicare's working-past-65 guidance flags stopping HSA contributions in advance of retirement or a Social Security application; obtain an individual tax review of the actual retroactive period. Do not turn that warning into a universal instruction to stop contributions six months before every person's 65th birthday.
Ask the payroll office how it will stop employer contributions as well as salary deductions. Ask a tax professional to reconcile any contributions already made for months affected by Medicare coverage. A contribution correction is a separate task from deciding how to pay qualified expenses from an existing HSA.
Make enrollment and plan comparisons separate tasks
Start with eligibility and effective dates. Then compare the actual FEHB or PSHB brochure with the Medicare arrangement under consideration. Record provider access, prescription arrangements, premiums, deductibles and coordination rules. A plan's advertised reimbursement or benefit does not settle whether delayed Part B enrollment is available.
For each answer, record the organization, representative, date and document section supporting it. If two offices give different dates, ask them to identify the assumptions behind each answer before cancelling coverage or submitting a replacement election. Preserve the discrepancy until an authoritative response resolves it.
Questions for the enrollment conversation
- Which current employment and group coverage qualify me for the enrollment period I intend to use?
- What evidence must the employer supply, and who will complete it?
- What happens if employment ends earlier than planned?
- Does a PSHB Part B requirement or exception apply separately to each covered family member?
- Which Medicare effective date affects my HSA contribution eligibility?
- How will I document coverage during any processing gap?
Keep confirmation receipts with the final timeline. A saved comparison, scheduled appointment or submitted application is not the same as confirmed enrollment. For related preparation, use the FEHB retirement eligibility record check and HSA and FSA retirement worksheet.
