FEHB and Medicare for Hawaii federal retirees
Hawaii has one of the highest concentrations of federal civilian employees in the U.S. — Pearl Harbor shipyard, Joint Base shipyards, the Department of Defense civilian workforce, the State Department's APCSS, NOAA, and many more. For federal retirees aging into Medicare, the FEHB-Medicare decision is one of the biggest financial decisions of retirement.
FEHB and Medicare basics
The Federal Employees Health Benefits (FEHB) program is the health insurance program for federal employees, retirees, and their families. When you retire and become eligible for Medicare:
- FEHB continues automatically as long as you keep paying premiums
- You can also enroll in Medicare Parts A and B
- You don't have to drop FEHB to enroll in Medicare
- FEHB and Medicare coordinate — Medicare typically pays first, FEHB pays second
Should you enroll in Part B?
This is the most common — and consequential — decision for federal retirees. The rules:
- Part A is free for nearly all federal retirees who paid Medicare taxes for 10+ years. Most enroll automatically at 65.
- Part B costs $202.90/month in 2026. There's no requirement to enroll if you have FEHB.
- If you don't enroll in Part B at 65 and decide to enroll later, you'll face permanent late enrollment penalties — 10% per year of delay, added to your premium for life.
Most FEHB plans strongly encourage Part B enrollment because it dramatically reduces your out-of-pocket costs:
- With Part B, Medicare pays first and FEHB pays second — you typically pay $0 for in-network covered services
- Without Part B, FEHB is your only payer and you have FEHB's deductibles, copays, and coinsurance
- Many FEHB plans waive deductibles and copays for Part B-enrolled members — some even partially reimburse the Part B premium
Hawaii's federal workforce
Major Hawaii federal employers and retirement bases:
- Pearl Harbor Naval Shipyard — one of the largest federal civilian employers in Hawaii
- Joint Base Pearl Harbor-Hickam DoD civilian workforce
- Schofield Barracks civilian workforce
- VA Pacific Islands Health Care System employees
- Daniel K. Inouye International Airport federal employees
- NOAA Pacific operations (Honolulu)
- NPS (Haleakala, Hawaii Volcanoes, Pearl Harbor parks)
- Pohakuloa Training Area civilian workforce
- State Department's Asia-Pacific Center for Security Studies (APCSS)
Major FEHB plans available in Hawaii
FEHB plan availability is national in some cases, regional in others. Hawaii federal retirees commonly choose between:
- Nationwide PPO plans like Blue Cross Blue Shield FEP, GEHA, NALC, MHBP — work anywhere in the U.S.
- Hawaii-specific HMO plans — Kaiser Permanente Hawaii is the most common HMO option
- HDHP options with HSA contributions
FEHB Open Season runs each November-December and applies regardless of your Medicare situation.
Do you need Part D with FEHB?
No, in nearly all cases. FEHB pharmacy coverage is creditable coverage equivalent to or better than Part D. You generally don't pay a Part D late enrollment penalty if you keep FEHB.
Some federal retirees find Extra Help (Low-Income Subsidy) plus a Part D plan would actually be cheaper if they qualify by income. This is rare but worth checking with Sage PLUS if your income is limited.
Suspending FEHB to try Medicare Advantage
One specialized option: federal retirees can suspend (not cancel) FEHB to enroll in a Medicare Advantage plan. If MA doesn't work out, you can re-enroll in FEHB during the next Open Season. Cancelling FEHB completely is permanent — suspension preserves the option to return.
This is an advanced strategy. Consult an FEHB specialist or Sage PLUS counselor before making the change.
FEHB and TRICARE
Federal civilian retirees who are also military retirees can have FEHB and TRICARE For Life (with Medicare Part B). The coordination of all three is complex but generally results in extremely low out-of-pocket costs. See our TRICARE For Life guide.
Frequently asked questions
No, but it's strongly recommended. Without Part B, FEHB is your only payer for outpatient services. With Part B, Medicare pays first and FEHB pays second, typically resulting in $0 out-of-pocket for in-network covered services. The Part B late enrollment penalty is permanent if you delay.
Some FEHB plans offer partial Part B premium reimbursement (typically $600-$1,200/year). This is a plan benefit that varies — check your specific plan. The Postal Service Health Benefits (PSHB) program for postal retirees does not include premium reimbursement.
Technically yes, but it's usually not advised. Most federal retirees either keep FEHB primary with Original Medicare, or suspend FEHB to try Medicare Advantage. The dual-enrollment route can create coordination headaches.
You can keep FEHB without Part B, but you may face higher out-of-pocket costs and a permanent Part B late enrollment penalty if you ever decide to enroll. There's no equivalent of TRICARE's mandatory Part B rule for FEHB — the choice is yours, but the financial consequences of skipping Part B are real.
Starting in 2025, postal retirees moved from FEHB into the new Postal Service Health Benefits (PSHB) program. PSHB requires Medicare Part B enrollment for retirees and their dependents who become Medicare-eligible at age 65 or later. The plans and benefits are similar to FEHB but enrollment in Part B is mandatory.
