Prior authorization with MultiPlan
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.
