TRICARE splits the country into two regions, each administered by a separate contractor rather than by TRICARE directly: Humana Military runs the TRICARE East Region and TriWest Healthcare Alliance runs the TRICARE West Region, both under contracts that took effect 1 January 2025. Six states, Arkansas, Illinois, Louisiana, Oklahoma, Texas and Wisconsin, moved from the East Region to the West Region on that same date, so confirm which contractor currently covers your state before applying.
Both regions credential primarily through CAQH ProView. TriWest's own provider page states that individual providers who participate in CAQH should list their CAQH ID on a provider roster and keep the profile complete and accessible; providers outside CAQH complete TriWest's own credentialing application instead. TriWest uses a third-party verifier, Aperture Credentialing, for primary source verification, and its own page confirms providers are scheduled for recredentialing every three years after initial credentialing. Neither contractor's own page states a specific day count for the initial credentialing decision; third-party guides quote ranges from 60 to 180 days, but none of those figures trace back to a page either contractor currently publishes, so no single timeline is claimed here.
Which contractor runs TRICARE credentialing in my state?
Humana Military administers the TRICARE East Region and TriWest Healthcare Alliance administers the TRICARE West Region, under contracts effective 1 January 2025. Arkansas, Illinois, Louisiana, Oklahoma, Texas and Wisconsin moved from the East Region to the West Region on that date, replacing the prior regional boundaries, so confirm your current region before starting an application.
| Region | Contractor | Effective |
|---|---|---|
| TRICARE East | Humana Military | 1 January 2025 |
| TRICARE West | TriWest Healthcare Alliance | 1 January 2025, replacing Health Net Federal Services |
How does TRICARE credentialing actually work?
Both regions credential primarily through CAQH ProView; TriWest's own page states that providers already in CAQH list their CAQH ID on a provider roster, while providers outside CAQH complete TriWest's own credentialing application and send it with supporting documentation. TriWest also uses a third-party verifier, Aperture Credentialing, which may contact applicants directly for additional information during primary source verification.
Neither contractor's own page states a specific day count for the initial credentialing decision. Third-party billing and vendor guides quote ranges anywhere from 60 to 180 days for TRICARE credentialing, but none of those figures trace back to a page either Humana Military or TriWest currently publishes, so no single timeline is claimed on this page. One region-specific figure, 60 to 180 days from Health Net Federal Services, describes the contractor TriWest replaced in the West Region as of 1 January 2025 and is no longer current.
No published timeline does not mean no process. Both contractors confirm CAQH ProView as the application channel and a recredentialing cycle, but neither states how long the initial decision itself takes. Confirm the current estimate directly with credentialing@triwest.com for the West Region or with Humana Military for the East Region rather than relying on a third-party figure.
How often do I need to re-credential with TRICARE?
TriWest's own page confirms providers are scheduled for recredentialing every three years following initial credentialing. This matches the three-year cycle already confirmed for Aetna, UnitedHealthcare, Cigna, Humana and Kaiser Permanente on this site.
Confirm your current region
Check whether your state falls under Humana Military (East) or TriWest Healthcare Alliance (West); six states changed regions on 1 January 2025.
Use CAQH ProView if you already have a profile
List your CAQH ID on the regional contractor's provider roster and keep the profile complete and accessible.
Complete the contractor's own application if you are not in CAQH
TriWest's own application is sent with supporting documentation directly to credentialing@triwest.com.
Primary source verification
TriWest uses Aperture Credentialing as a third-party verifier, which may request additional information directly.
Recredentialing every three years
Confirmed on TriWest's own provider page; budget the same cycle for the East Region until confirmed otherwise with Humana Military.
Confirm your region before applying
Six states moved from TRICARE East to TRICARE West on 1 January 2025; applying to the wrong contractor wastes the submission.
Do not trust an unsourced day count
Third-party guides disagree by over 100 days; neither contractor's own page states a specific timeline, so none is claimed here.
Budget three years for recredentialing
TriWest's own page confirms this cycle; the figure matches every other payer guide on this site.
