What Is the TRICARE West Region?
The TRICARE West Region is one of two domestic TRICARE regions, covering 26 states. As of January 1, 2025, TriWest Healthcare Alliance replaced Health Net Federal Services as the West Region contractor, and six states—Arkansas, Illinois, Louisiana, Oklahoma, Texas, and Wisconsin—moved from the East Region to the West Region. The West Region now covers Alaska, Arizona, Arkansas, California, Colorado, Hawaii, Idaho, Illinois, Iowa, Kansas, Louisiana, Minnesota, Missouri, Montana, Nebraska, Nevada, New Mexico, North Dakota, Oklahoma, Oregon, South Dakota, Texas, Utah, Washington, Wisconsin, and Wyoming.
Why the Region Changed
The Defense Health Agency awarded the T-5 contract to TriWest to administer the TRICARE West Region. This transition was designed to improve network adequacy, standardize provider data, and enhance the beneficiary experience. TriWest built a network of nearly 117,000 providers for the region, with 99% network adequacy for primary care and behavioral health.

How to Search for Providers in the TRICARE West Directory

Search Options
| Search Function | What It Does |
|---|---|
| Doctors by name | Search for a provider by entering their name to view locations, network status, and whether they are accepting new patients |
| Doctors by specialty | Search by specialty (e.g., general physician, cardiologist). You can also search by body part (e.g., “eyes,” “ears,” “heart”) |
| Places by name | Search for healthcare facility profiles by entering a facility name |
| Places by type | Search for healthcare facility profiles by entering a type |

Gender: Male or female providers
Languages spoken: Find providers who speak your language
Accepting new patients: Filter for providers currently accepting new patients
Telehealth availability: Filter for providers offering virtual visits

Search Tips
Search by body part. If you are unsure of the exact specialty name, enter a body part like “eyes,” “ears,” or “heart” to find relevant specialists.
Change your location. Select the Location hyperlink on the ribbon to change your search location. The directory provides results within 150 miles or less of your specified location.
Check your plan. The directory only shows providers that match your selected TRICARE plan. To view providers covered by a different plan, select the “My Health Plan” hyperlink and change your plan selection.
Look for HPP designation. Providers with the High Performing Provider designation are ranked higher in search results and have been evaluated for quality and value.
Use the telemedicine filter. Search specifically for providers offering telemedicine options specific to your TRICARE plan.
Network vs. Non-Network Providers: What You Need to Know
Network providers have a signed agreement with TRICARE and accept the TRICARE allowed amount as full payment for covered services. Non-network providers do not have an agreement with TRICARE, which means you may pay more out of pocket and may have to file your own claims.
Key Differences
| Factor | Network Provider | Non-Network Provider |
|---|---|---|
| TRICARE Agreement | Yes | No |
| Payment | Accepts TRICARE allowed amount as full payment | May charge up to 15% above the allowed amount |
| Claims Filing | Provider files claims | You may need to file your own claims |
| Out-of-Pocket Costs | Lower | Higher |
| Referral Requirements | Same as network | Same as network |
Why It Matters
Veterans May Qualify for Extra Benefits
Check available financial assistance, healthcare programs and other opportunities that may apply to you.
Check EligibilityUsing a network provider keeps your costs predictable. Network providers accept the TRICARE allowed amount as the full payment for covered services. Non-network providers do not have an agreement with TRICARE, and you may have to file your own claims. TRICARE-authorized non-network providers may charge up to 15% above the TRICARE allowed amount, but they cannot balance-bill you beyond that for covered services.
Finding Network Providers
Always search for “network” providers in the directory. The directory clearly identifies whether a provider is in-network. If you need care from a non-network provider because no network provider is available, TRICARE may authorize it, but you should confirm before receiving care.
Referrals and Authorizations in the West Region
Referrals and authorizations are managed through the TriWest beneficiary portal. TRICARE Prime enrollees generally need a referral from their primary care manager (PCM) for specialty care. TriWest processes referrals and authorizations for the West Region.
When You Need a Referral
TRICARE Prime: You need a referral from your PCM for most specialty care. Urgent care visits are exempt.
TRICARE Select: You do not need a referral for most specialty care, but you may pay higher costs if you see a non-network provider.
TRICARE For Life: You generally do not need referrals.
How to Check Referral Status
Log in to the West Region beneficiary portal at tricare.triwest.com. The Referrals/Authorizations page displays your referrals, and you can use the Referral/Authorization Decision Support (RADS) Tool to check if a referral is needed.
Processing Time
Allow 5–7 business days for an authorization to be completed. The authorization will include the authorized provider and contact information, number of visits, and the start and expiration dates authorized.
Referral Approval Waiver
TriWest implemented a referral approval waiver for TRICARE Prime enrollees referred for outpatient specialty care by their PCM. Under this waiver, referrals can proceed without requiring TriWest approval, streamlining access to specialty care.
How to Change Your Primary Care Manager (PCM)
You can change your PCM by logging in to milConnect, calling TriWest, or mailing a TRICARE Prime Enrollment, Disenrollment, and PCM Change Form (DD Form 2876). The West Region form is DD 2876-2.
Steps to Change Your PCM
Find a new PCM using the provider directory. Call the provider first to confirm they are accepting new patients.
Log in to milConnect or call TriWest at 888-TRIWEST (874-9378).
Submit the DD Form 2876-2 by mail if changing by mail. Include the new PCM’s name and address.
Confirm the change with TriWest. Your new PCM assignment takes effect once processed.
Drive Time Standards
Beneficiaries outside the drive time standard no longer need a waiver to stay in TRICARE Prime. Those who live within 100 miles of a military hospital or clinic but at least 30 minutes away by car no longer need a waiver.

Common Mistakes to Avoid
Finding a TRICARE West provider is straightforward if you avoid these errors.
Using the old Health Net directory. Health Net Federal Services is no longer the West Region contractor. Use the TriWest provider directory at tricare.mil/west[reference:32].
Not selecting your plan. The directory only shows providers that match your selected TRICARE plan. If you do not select a plan, you may see incomplete or incorrect results.
Assuming all providers accept TRICARE. Always verify network status in the directory. Non-network providers may charge more and require you to file claims.
Not checking whether the provider is accepting new patients. The directory shows this information, but you should always call the provider to confirm before booking.
Forgetting to check referral requirements. TRICARE Prime enrollees need a referral for most specialty care. Check the RADS tool or call TriWest before booking.
Missing the High Performing Provider designation. HPP providers are ranked higher in search results and have been evaluated for quality and value. Look for this designation when choosing a provider.
Not updating payment information after the 2025 transition. If you pay by credit card or bank transfer, ensure your payment information is updated with TriWest.
Assuming your old PCM is still in network. Provider networks changed on January 1, 2025. Verify that your PCM is in the TriWest network.
