Blue Cross Blue Shield of Wyoming announced Tuesday that between 7,000 and 7500 of its members have been over-charged due to an error by American National Bank. The bank has taken full responsibility and has acted quickly to reverse and credit members’ accounts for the incorrect duplicate charges. The bank and Blue Cross Blue Shield anticipate that the impacted accounts will show the corrections now, subject to the procedures of individual banks. Blue Cross Blue Shield contacted the Wyoming Department of Insurance immediately after the error was identified. The company says this banking error should not impact insurance coverage by Blue Cross Blue Shield. However, members are advised that if their account does not reflect the correction today, they should contact Blue Cross Blue Shield of Wyoming.
