As the new year begins, many government employees and military families take time to review their healthcare costs and plan for the months ahead. If you’re enrolled in a TRICARE health plan (Prime, Select, or other options), you’ve probably encountered terms like deductible, copayment, cost-share, and catastrophic cap. Knowing what these mean and how they work together can help you better anticipate your healthcare spending in 2026.
1. What Is a Deductible?
A deductible is the amount you must pay out-of-pocket for covered services and prescriptions before TRICARE begins sharing costs according to your plan’s rules. Not all TRICARE plans have deductibles:

2. Copayments and Cost-Shares: Your Portion for Care
After meeting your deductible (if your plan has one), most covered services — like doctor visits, procedures, urgent care, and prescriptions — require a copayment (a fixed fee) or cost-share (a percentage of the allowed charge).
These payments count toward your overall out-of-pocket spending for the year. Official definitions for copayments, cost-shares, and deductibles are available on TRICARE’s Cost Terms page:

3. The Catastrophic Cap: Your Financial Safety Net
One of TRICARE’s most important protections is the catastrophic cap — the maximum amount you or your family will pay out-of-pocket for covered TRICARE services in a calendar year (January 1 through December 31).
TRICARE’s official explanation of the catastrophic cap can be found here:

Most out-of-pocket costs contribute toward reaching this cap, including:
Some items do not count toward your catastrophic cap, such as:

Once you and your family reach the catastrophic cap for a calendar year, TRICARE will cover 100% of the TRICARE-allowable cost of covered services for the rest of the year (except for items that don’t count toward the cap). This means no more copays or cost-shares on covered care — a significant protection against unexpected high medical expenses.
4. How Much Is the Cap in 2026?
Your exact catastrophic cap depends on your TRICARE plan and beneficiary group.
