Summary
BCBS Rhode Island has clarified that State of Rhode Island employee member ID prefix must be 'R2I' (R-2-letter I), not 'R21' (R-2-number 1). Claims are being denied due to incorrect prefix usage in billing submissions.
Action Required
Immediately: Billing team must verify all BCBS Rhode Island State employee claims use prefix 'R2I' (R-2-letter I) instead of 'R21' (R-2-number 1). Update billing system validation rules to prevent incorrect prefix entry. Review and resubmit any recently denied claims that used the wrong prefix.
