Stop Overpaying: How FEHB & Medicare Slash Retirement Costs Together
Federal Retiree Health Insurance: Understanding FEHB and Medicare Made Simple
This content is sponsored by FEBA.
Why This Matters for Federal Retirees
If you worked for the federal government, you have some big decisions to make about health insurance when you retire. Two major programs—FEHB (Federal Employees Health Benefits) and Medicare—can work together like a team. Knowing how they fit together can save you money and give you better coverage.
Think of it like this: FEHB is the health plan you had while working. Medicare is a government program that starts at age 65. You can use both at the same time, but the rules change once you retire.
Keeping Your FEHB Coverage After You Retire
You can keep your FEHB plan for life if you meet two rules:
- You retire on an "immediate annuity" (meaning you start getting your pension right away).
- You were enrolled in FEHB for the 5 years right before you retired (or since your very first chance to enroll).
Good news for your family:
- Your spouse, dependent children, and eligible children with disabilities can stay on your plan without meeting the 5-year rule.
Who pays what?
- The government still pays about 70–75% of the premium (up to a legal limit).
- Premiums come out of your monthly annuity check.
- Big difference: These deductions are after-tax (you already paid taxes on that money). While you were working, they were pre-tax.
Special Rules for Postal Retirees
IMPORTANT: If you retired from the Postal Service, different rules apply!
Under the Postal Service Reform Act of 2022, most Medicare-eligible postal retirees must enroll in Medicare Part B to keep their health coverage through the new Postal Service Health Benefits (PSHB) Program (started in 2025).
- There are limited exceptions.
- Postal retirees should review their specific situation carefully.
Medicare Basics: The Four Parts
Medicare usually starts at age 65. For most federal retirees, signing up is optional but highly recommended—except for postal retirees (see above).
| Part | Name | What It Covers | Cost |
|---|---|---|---|
| Part A | Hospital Insurance | Inpatient hospital stays | Free for most (if you worked enough years) |
| Part B | Medical Insurance | Doctor visits, outpatient care, preventive services | Monthly premium (higher if your income is higher — called IRMAA) |
| Part C | Medicare Advantage | Private plans combining A + B + often extra benefits (dental, vision, etc.) | Must have A & B first; premiums vary |
| Part D | Prescription Drugs | Helps pay for medications | Optional; many FEHB plans already have creditable drug coverage |
When to Sign Up for Medicare (And What Happens If You’re Late)
- While you’re still working and covered by FEHB: That counts as "employer coverage." You can delay Part B without penalty.
- After you retire: Medicare usually becomes primary (pays first), and FEHB becomes secondary (pays second) — but only if you enroll in Medicare.
- If you delay Part B without qualifying coverage: You face a permanent late penalty (10% higher premium for every 12 months you waited).
Simple rule: Once you retire, the clock starts ticking on Part B. Don’t wait too long unless you have active employer coverage.
FEHB: Cancel or Suspend?
If you have Medicare, Medicaid, or TRICARE for Life, you have two choices for your FEHB plan:
Canceling FEHB
- Permanent. You cannot re-enroll later.
- Only do this if you’re 100% sure you’ll never want FEHB again.
Suspending FEHB (Usually the Better Choice)
You can pause FEHB if you enroll in:
- A Medicare Advantage (Part C) plan
- Medicaid
- TRICARE for Life
Why suspend? You keep the right to come back during a future Open Season or after a qualifying life event (like losing other coverage).
For most retirees, suspending gives you flexibility. Canceling does not.
Three Smart Strategies to Combine FEHB and Medicare
There’s no single "best" plan—it depends on your life. Here are three common approaches:
1. Keep FEHB + Enroll Only in Medicare Part A
- Part A is free, so most people sign up at 65.
- You keep FEHB as your main coverage.
- Great for: Travelers! Medicare doesn’t cover care outside the U.S., but many FEHB plans do.
- Risk: If you skip Part B now and want it later, you’ll pay lifetime penalties (10% per year of delay).
2. Enroll in Medicare Parts A & B + Keep FEHB
- Medicare pays first; FEHB pays second (often covering most or all remaining costs).
- Many retirees switch to a lower-cost FEHB plan (like a "Basic" option) to save on premiums.
- Some Basic plans even give rebates to help pay your Part B premium.
- Cost: Highest monthly premium, but best protection against big medical bills.
3. Suspend FEHB + Join a Medicare Advantage Plan (Part C)
- You need Parts A & B first.
- Many Advantage plans have $0 extra premium (beyond Part B).
- You suspend (not cancel) FEHB — so you can return later if needed.
- Cost: Usually the lowest monthly cost.
- Trade-off: You may pay more out-of-pocket when you get care (copays, coinsurance).
How to Choose the Best Option for You
Ask yourself these five questions:
- What’s my income? (Higher income = higher Part B premiums due to IRMAA)
- How’s my health? (Do you expect lots of doctor visits or hospital stays?)
- Do I travel outside the U.S.? (Medicare won’t cover you there)
- What prescriptions do I take? (Check if your drugs are covered)
- Am I a Postal or non-Postal retiree? (Different rules apply!)
Pro tip: Review your coverage every year during Open Season. Premiums, plans, and your health needs change.

Summary
- FEHB can continue into retirement if you meet the 5-year rule and retire on an immediate annuity.
- Postal retirees: Most must enroll in Medicare Part B to keep PSHB coverage.
- Medicare has 4 parts — A (hospital), B (doctor), C (Advantage), D (drugs).
- Don’t delay Part B without a reason — penalties are permanent.
- Suspend, don’t cancel FEHB if you try Medicare Advantage or TRICARE.
- Three main strategies: (1) FEHB + Part A only, (2) FEHB + Parts A & B, (3) Suspend FEHB + Medicare Advantage.
- Pick based on: income, health, travel, drugs, and postal vs. non-postal status.
- Review annually during Open Season.
Frequently Asked Questions
1. Do I have to sign up for Medicare at 65 if I have FEHB?
For most federal retirees: No, it’s optional. But if you’re a Postal retiree, you must enroll in Part B to keep PSHB coverage. Even if optional, Part A is free — so almost everyone should take it.
2. What’s the difference between canceling and suspending FEHB?
- Canceling = gone forever. You can’t get it back.
- Suspending = paused. You can re-enroll later during Open Season or after a life event (like losing other coverage). Suspend if you might want FEHB again.
3. Will Medicare cover me if I travel to another country?
No. Medicare generally does not cover care outside the U.S. If you travel internationally, keeping FEHB (Strategy 1 or 2) is smart because many FEHB plans offer overseas coverage.
4. What is IRMAA and does it affect me?
IRMAA (Income-Related Monthly Adjustment Amount) is an extra charge on your Part B (and Part D) premium if your income is above a certain level. It’s based on your tax return from two years ago. Higher income = higher Medicare premiums.
5. Can I switch strategies later?
- You can switch FEHB plans every year during Open Season.
- You can go from Strategy 1 → 2 by adding Part B later (but may face penalties).
- You can re-enroll in FEHB if you suspended it (not canceled).
- You cannot easily drop Part B once enrolled — so choose carefully at the start.
