Timely filing & appeals for One Call
This registry lists 90 days as an initial-claim reference for One Call. Confirm the applicable product, provider agreement, start event and current payer instructions. Do not apply this value automatically to out-of-network, secondary, corrected or appealed claims.
| Submission type | Window |
|---|---|
| Initial claim reference | 90 days (verify applicability) |
| Out-of-network initial claim | Verify the member's plan and applicable out-of-network rules |
| Secondary / coordination of benefits | Verify the allowed window and start event; a primary EOB does not automatically restart filing |
| Corrected claim | Verify correction instructions; do not substitute an appeal deadline |
| Reconsideration / appeal | Use the applicable denial or decision notice and the process below |
This registry has not established a payer-specific appeal ladder for One Call. Use the denial notice, plan document, provider agreement, or jurisdictional rule to assign the correct route and deadline. Missing registry evidence does not mean appeal rights are unavailable.
Source: One Call provider policy. Always confirm before disputing a TFL denial — payer policies are versioned and product-specific.
Prior authorization with One Call
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 One Call 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 One Call. 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.
