Billing a patient with a YOG member ID
- 1
Verify eligibility through BCBS of Massachusetts or the BlueCard eligibility line before the visit — coverage and benefits are governed by the member's home plan.
- 2
Submit the claim to your local Blue plan, which routes it to BCBS of Massachusetts through the BlueCard® program. Include the full member ID with the YOG prefix exactly as printed on the card.
- 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
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.
