Centene / Ambetter: timely filing limit
Initial claim
No published default
Timely filing limits vary by contract. We could not confirm a single default limit that applies across every Centene / Ambetter contract, so we are not going to state one. Check your own participation agreement, or the payer portal, before relying on a number for this deadline.

No published default appeal window. Check the payer's own appeals policy.
Caveats
Centene operates Ambetter marketplace plans and other lines of business separately in each state (for example Home State Health, Superior HealthPlan), and each state plan publishes its own quick reference guide with its own timely filing figure. Because the numbers found during this research were inconsistent across states, no single default is asserted here; confirm against the specific state Ambetter or Centene affiliate provider manual.
