Timely filing & appeals for TRICARE West

TRICARE West claims guidance uses one year from service or inpatient discharge, not a universal 365-day calculation. Other-health-insurance claims have separate timing from OHI adjudication; confirm the current rule, claim type and exceptions. The recommendation to file within 30 days is not the filing limit.

Prior authorization with TRICARE West

Decision deadlines depend on the product, service and urgency. CMS-0057-F generally starts its decision-timeframe requirements in 2026 for Medicare Advantage, Medicaid and CHIP payers subject to the rule: seven calendar days for standard requests and 72 hours for expedited requests. Those requirements exclude drug authorizations and QHP issuers on the federally facilitated exchanges. Other plans, state rules and permitted extensions can differ. Check the applicable policy; a decision deadline is not a guarantee of approval.

CMS-0057-F decision-timeframe requirements and exclusions

Verify TRICARE West electronic claims (837), eligibility (270/271), remittance (835) and authorization (278) separately for the member product and clearinghouse. Registry flags and routing references are not current transaction-complete approval. Confirm the companion guide, enrollment and applicable source findings below. A blank or unverified field does not establish that the transaction is unavailable. Authorization requirements and submission channels depend on the product, service and delegated reviewer. Verify the applicable policy before scheduling; a portal listing is not proof of X12 278 connectivity.

This registry does not provide a current prior-authorization code list for TRICARE West. Start with the provider resources or the policy documents below, then confirm the applicable product, service and effective date. A resource link does not establish that a live code-lookup tool is available.

What revenue cycle teams should verify before submitting claims

  • Use 99726 for TRICARE West claim submission to PGBA, and confirm eligibility/remit mappings such as TRICW in the provider's clearinghouse.
  • Submit referrals and authorizations through Availity under TRICARE West/TriWest Payer Spaces.
  • Secondary claims with Other Health Insurance must be submitted within the separate OHI timing rule after primary adjudication.

Common denial and routing risks for this payer

  • Using legacy TRICARE West or VA CCN payer IDs after the TriWest transition.
  • Missing referral or authorization requirements for Prime and specialty care services.
  • Submitting OHI secondary claims outside the TRICARE West post-primary-adjudication window.

How QuickIntell supports this workflow

  • Split TRICARE West claim routing from VA Community Care and CHAMPVA routing so similar government names do not collide.
  • Use authorization workqueues tied to Availity referral status before releasing scheduled services.
  • Track TRICARE reconsideration and appeal clocks directly from the remittance advice date.
