Can a claim go through THIN without alpha prefix?
A. You may submit your claim to THIN, who will try to locate a membership record. If, however, a membership record cannot be found, the claim will be returned to you. BCBSTX recommends that you contact the appropriate Customer Service Department, found on the back of the member’s ID card, to obtain the correct alpha prefix for that date of service or obtain alternate claim filing instructions in the absence of the three digit alpha prefix.
