Effective immediately, please indicate your referral number from Health Trio on your CMS-1500 form in box 23. Health Trio is the vendor we use to load electronic referrals into their portal. PCPs load the referral for specialists, and specialists are able to view the referrals by member. Your confirmation number from Health Trio is the referral number. This will help the Claims Department select your referral, and understand if your office was able to obtain the referral through Health Trio. This new process will ensure your claim is processed to the correct referral in case there are multiple referrals on file for the same group/TAX ID. If you have any questions related to this change, please contact Provider Relations at ProviderRelations@bcbsri.org.
