Out-of-state Blue Cross claims go to your local Blue plan

Your local plan routes each claim to the patient's home plan by the three-character prefix on the member ID, then pays you for the visit.

Your patient's Blue Cross card comes from another state's Blue plan, and the claim came back denied or paid to your patient. Send the claim to your local Blue plan, the plan for the area where you see your patient.

1. Enter the member ID exactly as printed. The ID opens with three characters, letters or numbers, called the prefix. The prefix picks the home plan. Your local plan reads the prefix and routes your claim to that plan, so don't add or drop a character, the BlueCard Program Provider Manual says.
2. Send the claim to your local Blue plan. Your local plan is your sole contact for payment, adjustments, and problems with the claim. Ask that plan for the claim's status. Your local plan pays you. The remittance comes from that plan too.
3. Check whether BlueCard excludes your patient's coverage. BlueCard excludes Medicare Advantage, state Medicaid, the Federal Employee Program, and stand-alone dental coverage. Federal Employee Program IDs start with the letter R. Your local plan's manual gives the filing rules for that coverage.
4. Ask your local plan about an unpaid or denied claim. Appeals for every BlueCard claim go through your local plan. Don't send a second copy of a claim your local plan is still processing, since the plan denies the copy as a duplicate. The home plan may ask you for the claim. Refer that plan to your local plan.

One exception: a contract with a neighboring Blue plan

Your office may sit near another Blue plan's area. The neighboring plan can sign a contract with you, per the manual's June 2026 edition. That contract may let you file claims with the neighboring plan directly, so read your contract before you file anywhere but your local plan.
