Some identification cards may not include an alpha prefix, which may indicate that the claim filing instructions for these type policies are different. We suggest that you verify claim filing instructions during the time eligibility information is obtained. If not, please follow the instructions on the back of the member’s ID card or contact the plan directly. Member eligibility can be obtained at 1 (800) 676-BLUE (2583). Once connected, you will then simply provide the alpha prefix and the operator will then route you to the member’s plan. Helpful Tips Related to the Alpha Prefix:

• Do not omit or randomly select an alpha prefix.
• Do not substitute another Blue Cross Blue Shield Member’s prefix.
• Include the alpha prefix and all alpha numeric characters preceding the alpha prefix on all correspondence and claims submitted to Blue Cross Blue Shield of Texas.
• The alpha prefix is always three letters followed by the member’s ID number which can be from 6 up to 14 characters total.
• If possible, make copies of the member’s ID card (front and back) for your records.
• We recommend that you obtain a copy of the ID card any time there has been a coverage or policy change. If there are no changes, we suggest that you obtain card copies annually.
