Medicare for Hawaii veterans and military retirees

Hawaii has more than 110,000 veterans and one of the largest military-retiree communities in the Pacific. How TRICARE For Life and VA health care each work with Medicare — explained by a retired Air Force officer who has been through the paperwork himself.

At a glance

TRICARE For Life requires Medicare Part A and Part B and pays secondary to Medicare. Its pharmacy is creditable, so a separate Part D plan is usually unnecessary, and a Medigap policy usually is too.
VA health care does not coordinate with Medicare. VA medical coverage is not creditable for Part B, so delaying Part B because you have VA care can trigger a lifelong penalty; VA pharmacy is creditable for Part D.
The state Office of Veterans’ Services counts roughly 112,000–117,000 veterans in Hawaii: about 85,000 on Oahu, 16,000 on Hawaii Island, 11,000 in Maui County and 4,000 on Kauai. About 13,000 military retirees and 18,500 retiree family members are covered under TRICARE in Hawaii.
VA care runs through the VA Pacific Islands Health Care System: the Spark M. Matsunaga VA Medical Center on the Tripler campus, the Daniel K. Akaka VA Clinic in Kapolei (opened 2024), and clinics in Hilo, Kailua-Kona, Maui and Kauai, with a VA physician on Molokai three days a week and visiting clinicians on Lanai.
With TRICARE For Life, an MA-only plan (Advantage without drug coverage) can add dental or vision without duplicating your prescription benefit.

Hawaii’s veterans are concentrated where the bases are — Pearl Harbor and Hickam, Schofield Barracks and Wheeler, Marine Corps Base Hawaii at Kaneohe Bay — and scattered across every island. How your military benefits coordinate with Medicare depends a lot on which benefit you have.

TRICARE For Life (TFL)

Requires you to have Medicare Part A and Part B.
Pays secondary to Medicare — it wraps around Medicare like a supplement.
TFL pharmacy is creditable, so a separate Part D plan is usually unnecessary.
TFL can pair with a Medicare Advantage plan; because drug coverage already exists, an MA-only plan (Advantage without Part D) can add dental or vision without duplicating your Rx.
Because TFL already fills Medicare’s gaps, a Medigap policy is usually unnecessary too.

VA health care

Separate from Medicare — the two do not coordinate and don’t disrupt each other.
Medicare doesn’t pay at VA facilities; the VA doesn’t cover Medicare cost-sharing.
VA medical is not creditable for Part B — enroll in Part B on time to avoid a lifelong penalty.
VA pharmacy is creditable for Part D, so you can rely on it for drug coverage.
Having both Medicare and VA gives you more places to get care — Queen’s, Straub or Kaiser with Medicare, the VA for service-connected care and prescriptions.

The mistake we most want you to avoid: skipping Part B because you have VA care. Because VA medical coverage isn’t creditable for Part B, delaying it can trigger a penalty that lasts as long as you have Medicare, and it leaves you with no coverage at a non-VA hospital. If you are approaching 65 with VA benefits, talk to us about timing first.

Where VA care is in Hawaii

The VA Pacific Islands Health Care System is based at the Spark M. Matsunaga VA Medical Center on the Tripler campus in Honolulu, where the VA shares inpatient care with Tripler Army Medical Center under a VA/DoD agreement. The Daniel K. Akaka VA Clinic in Kapolei, opened in April 2024, brought primary care, specialty care, imaging and urgent care to West Oahu. Community clinics serve Hilo, Kailua-Kona, Maui and Kauai; a VA physician sees patients at the Molokai Rural Health Center three days a week, and traveling clinicians visit Lanai. For a neighbor island veteran the practical point is that VA specialty care often means a flight to Honolulu, which is one more reason to hold Medicare alongside the VA for care closer to home.

Military hospitals after 65

Tripler Army Medical Center continues to see retirees on a space-available basis under TRICARE rules. Medicare does not pay there. Most Hawaii military retirees pair TFL with civilian care nearby, and we have pages for the three big retiree communities: Joint Base Pearl Harbor-Hickam, Schofield Barracks and Wheeler and Marine Corps Base Hawaii.

Which Hawaii plan fits a veteran

VA care plus Original Medicare and a Medigap policy gives the widest choice: any hospital on any island, no network question, VA pharmacy for drugs. Many veterans skip Part D entirely because the VA pharmacy is creditable — keep the VA’s letter as proof.
VA care plus a $0-premium Advantage plan is common and can work, as long as you understand the network limits and that the VA and the plan will not coordinate a single bill. Kaiser members need Kaiser Senior Advantage to keep Kaiser.
TFL plus an MA-only plan for dental, vision and hearing, if the extras are worth it and the network reaches your doctors.

How we help

We look at exactly which benefits you carry, confirm your Part B timing, decide whether a separate drug plan adds anything, and — if it makes sense — compare an MA-only or Medigap option for the gaps. Darin served 22 years in the Air Force and retired as an officer; he has filled out the same forms you are looking at.

Good to know

Frequently asked questions

I have VA health care. Do I need Medicare Part B?

In most cases, yes — enroll on time. VA medical coverage is not considered creditable for Part B, so delaying Part B can cause a permanent late penalty. Having both VA and Medicare gives you more options for where to get care, which matters on an island where the VA clinic is small.

With TRICARE For Life, do I need a Part D drug plan or a Medigap policy?

Usually neither. TRICARE For Life pharmacy is creditable drug coverage, and TFL already pays secondary to Medicare, filling the gaps a supplement would. That is also why an MA-only plan can make sense if you want dental or vision.

Does Medicare pay at Tripler or the Matsunaga VA?

No. Medicare does not pay at military or VA facilities, and they do not cover Medicare cost-sharing. They operate separately, which is why many veterans keep both.

Is VA pharmacy coverage enough to avoid the Part D penalty?

Yes. VA prescription coverage is creditable for Part D, so you can skip a Part D plan without a penalty as long as you keep it. Keep the VA’s notice of creditable coverage in case you enroll in Part D later.
