ID Card

Blue Cross and Blue Shield of Texas (BCBSTX) offers a wide variety of health care products. Each member's/subscriber's identification (ID) card displays important information required for billing and determining benefits. When filing a BCBSTX claim, two of the most important elements are the member's/subscriber's ID number and group number

Most members with coverage through a Blue Cross Blue Shield Plan are assigned a three letter alpha prefix that appears at the beginning of their unique identification number. The alpha prefix is very important to the identification number as the prefix acts as a key element in confirming the member's eligibility and coverage information. Prefixes are also used to identify and correctly route claims to the appropriate Blue Cross Blue Shield Plan for processing.

There are two types of alpha prefixes: plan-specific and account-specific. The plan-specific alpha prefixes are assigned to every Blue Cross Blue Shield plan and start with X, Y, Z or Q. The first two positions indicate the Plan to which the member/subscriber belongs while the third position identifies the product in which the member/subscriber is enrolled.

The account-specific alpha prefixes are assigned to national accounts; national accounts are employer groups that have offices across multiple states and offer uniform coverage benefits to their employees and the alpha prefix assigned to the national account will associate to the employer's name.

The member's network can be identified with the (3) character network value that is displayed in a red font on the front of the ID card. The network value will appear on Medical Identification cards where network benefits may apply.

Blue Choice PPO Network = BCA
Blue Essentials = HMO
Blue Advantage HMO = BAV
Blue Premier = HMH

If "TDI" is indicated on the ID Card, subject to TDI rules & regulations
