Billing Excellus BlueCross BlueShield from outside New York?

Usually you do not send the claim to Excellus BlueCross BlueShield. Under the BlueCard program, a provider treating a member from another Blue plan submits the claim to their own local Blue Cross Blue Shield plan, which then routes it to Excellus BlueCross BlueShield for processing.

The payer ID and claims address above are for filing within New York. Filing from elsewhere, use your local plan's details instead.
Prior authorizationis generally handled by the member's home plan — so Excellus BlueCross BlueShield, wherever you are.
Your timely filing limit is set by your own contract with your local Blue plan, not by the figure above. 365 days is customary but contracts vary.
To check eligibility and benefits for an out-of-area Blue member, call 1-800-676-BLUE (1-800-676-2583).

Arrangements vary by contract, and self-funded (ASO) accounts can differ — confirm with your local Blue plan before filing. See the BlueCard Program Provider Manual for the full rules.
