Avoiding/Correcting This Error

The MBI is necessary for all claims submitted to MAC. Claims without a correct MBI are rejected, requiring providers to verify and resubmit them. To avoid this, use the Eligibility Lookup in NGSConnex before submitting claims for Medicare patients. If the MBI or identification card is unavailable, use the MBI Lookup Tool in NGSConnex with the patient’s name, date of birth, and Social Security Number, as NGS cannot release identification numbers to providers. If a verified MBI results in claim rejection, the patient should contact their local Social Security office to verify their Medicare benefits and enrollment.
