Blue Cross Blue Shield (plan varies): 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 Blue Cross Blue Shield (plan varies) 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.

Caveats
Blue Cross Blue Shield is a federation of separately operated local companies (for example Highmark, Horizon, Independence Blue Cross, BCBS of Massachusetts, BCBS of Texas, and Florida Blue), each of which sets its own timely filing limit and appeal deadline. Always identify and confirm against the specific local Blue plan's own provider manual rather than treating BCBS as one payer.
