Prior authorization with Gallagher Bassett
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.

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.

What revenue cycle teams should verify before submitting claims
- The public claimant help page directs existing-claim questions to the assigned Resolution Manager and explains the GBGO mygbclaim app. This is claimant assistance, not a verified provider medical-bill submission portal.
- Client platform access and claimant contacts serve different audiences. Confirm provider bill routing, claim jurisdiction, filing requirements, and bill disputes with the responsible claim administrator; do not apply a generic commercial appeal ladder.
