Billing a patient with a T6R member ID
- 1
Verify eligibility through Highmark BCBS of West Virginia 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 Highmark BCBS of West Virginia through the BlueCard® program. Include the full member ID with the T6R 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.

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.
