Should you stay with Original Medicare or choose a Medicare Advantage plan? Learn how each option works with Tricare For Life, including claims, provider networks, Part B premium reductions, prescription drug coverage, and more.

When a military retiree turns 65, they transition into Tricare for Life with Medicare A & B, but what happens to younger spouses and children? This guide explains how family coverage continues, how premiums are affected, and what you need to know to avoid surprises during this transition.

If a spouse turns 65 before the retiree is 62, coverage doesn’t stop, but it looks different for a few years. At 65, the spouse must enroll in Part B and Tricare Prime or Select will act as secondary coverage. Then, when the retiree turns 62, the spouse becomes eligible for premium-free Part A and transitions into Tricare for Life, with Medicare as primary and TFL as secondary.

Many retirees are surprised when their Medicare premiums are higher than expected. This extra cost, called IRMAA (Income-Related Monthly Adjustment Amount), affects Medicare Part B and Part D if your income is above certain thresholds. In this post, we’ll explain what IRMAA is, why it exists, how it impacts Tricare for Life, and what steps you can take to plan ahead or appeal if your income has changed.

New to Tricare for Life? This guide breaks down the basics in plain language—what TFL is, who’s eligible, how it works with Medicare, and what you might still pay out-of-pocket. Whether you’re approaching age 65 or supporting a retiree, this post will help you feel confident about your healthcare coverage.
