Do I Need Supplemental Insurance When I Have Medicare and TRICARE for Life?

Medicare and TRICARE for Life (TFL) together cover most hospital and medical costs, but they do not eliminate all out‑of‑pocket expenses; a supplemental plan can help cover remaining gaps such as Medicare Part B deductibles, copayments, and services not covered by TFL.

How Medicare and TRICARE for Life Work Together

Medicare serves as the primary payer for TFL beneficiaries; TFL acts as secondary coverage, picking up most costs after Medicare has paid. This coordination means that hospital stays, physician visits, and many prescription drugs are largely covered, but each program retains cost‑sharing responsibilities.

Typical Gaps Left Uncovered

• Medicare Part B deductible ($226 in 2024) and coinsurance (20% of allowed amount)
• Non‑covered services such as most dental, vision, and hearing care
• Out‑of‑network care where TFL may only reimburse a portion
• High‑cost specialty drugs not on Medicare's formulary

When Supplemental Insurance May Be Beneficial

If you anticipate frequent medical visits, have chronic conditions, or prefer predictable monthly costs, a supplemental (Medigap) policy can fill the 20% Medicare Part B coinsurance and cover the deductible. Some plans also offer broader networks for out‑of‑state care, which can be useful for military families that relocate.

Considerations Before Adding a Supplemental Plan

Because TFL already covers many costs that a Medigap plan would pay, the added premium may not provide proportional savings. Compare the monthly cost of a supplemental plan against your expected out‑of‑pocket expenses. Also, check whether the supplemental policy is compatible with TFL's secondary coverage rules; most insurers allow stacking, but some may limit payments.

Alternative Strategies

Instead of a full Medigap plan, you might use a health‑savings account (HSA) or a limited supplemental policy that only addresses the Part B deductible. Reviewing your annual Medicare Summary Notice and TFL statements can reveal recurring charges that a targeted supplemental plan could eliminate.
