Billing a patient with a J5P member ID

  1. 1

    Verify eligibility through Yet to be assigned or the BlueCard eligibility line before the visit — coverage and benefits are governed by the member's home plan.

  2. 2

    Submit the claim to your local Blue plan, which routes it to Yet to be assigned through the BlueCard® program. Include the full member ID with the J5P prefix exactly as printed on the card.

  3. 3

    Track timely filing against the home plan's rules — BCBS filing limits vary by plan and contract, so check our timely filing limits directory and confirm the window that applies to your participation status.

  4. 4

    If the claim denies for eligibility or wrong payer, re-verify the prefix — members change plans often and old cards stay in circulation.

Prefix assignments change without notice. Always confirm with the payer or the member's current ID card before filing.
