Defense Heath Agency TRICARE Health Plan Office

Defense Heath Agency TRICARE Health Plan Office (DHA THP) manages and oversees an integrated health care delivery system in the two U.S. TRICARE regions. 

In most cases, you'll call your regional contractor first:

TRICARE East	TRICARE West
Humana Military 1-800-444-5445	TriWest Healthcare Alliance 888-TRIWEST (874-9378)

But, there are times when you will need to call DHA THP:

• Approval for the Prime Travel Benefit
• Determination of eligibility requests for TRICARE Prime Remote 
• If your issue is unresolved with the regional contractor
