1TRICARE T-5, the West region
TRICARE is the Department of Defense program that supports the health care of service members and their families. Its operation divides the country into regions, with a private insurer taking on "managed-care support" in each. This contract has TriWest Healthcare Alliance take on the "West Region" as the 5th generation (T5) contract.
2Its relation to T3 and the East region
This site also covers an earlier-generation (T3) South Region contract and the paired 5th-generation "East Region" contract (awarded to Humana).
Placed side by side, they concretely show TRICARE's structure of "dividing the same program by region and re-competing contracts by generation." Military health care is a major pillar of defense spending, and outsourcing its operation as large contracts to private insurers is a notable area where defense and health care (the health industry) intersect.
3What the public record covers
The description (USAspending) goes as far as "TRICARE 5th Generation West Region managed-care support" and does not detail benefits or operations (this site does not fill in what the description omits). A cumulative ~$8.40B shows how large a government-procurement market the operation of military health care is.
4Supporting the care, or providing it
The Defense Health Agency contracts for more than managed-care support. Among the records this site holds as of 2026-09-01 are contracts for providing comprehensive health care itself.
| Contractor | What the contract covers | Obligated |
|---|---|---|
| TriWest (this award) | Fifth-generation West Region managed-care support | about $8,404.61 million |
| Johns Hopkins | Comprehensive healthcare services | about $4,179.84 million |
| Martin's Point | Comprehensive healthcare services | about $3,588.92 million |
Managed-care support covers the running of the system — building networks, coordinating referrals, processing claims — while the care itself is delivered by providers. A comprehensive healthcare services contract, by contrast, covers the delivery. Both come from the same awarding office, so summing amounts alone mixes spending of different character. Describing the scale of military health care means keeping that distinction.
