Prior authorization with Cofinity
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 Cofinity 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 Cofinity. 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.
