Statistics shows that providers are doing a great job with the Medicare card transition. However, vendors and business associates may have missed the memo, and could still be submitting claims with the old numbers. Details: According to the Centers for Medicare and Medicaid Services (CMS), on or after Jan. 1, 2020, your claims must be submitted with the Medicare Beneficiary Identifiers (MBIs) “no matter what date you performed the service.” And that includes submissions from your vendors and/or clearinghouses, an MLN Connects suggests. If the claims you send to your vendors/clearinghouses come back and “you see both the Health Insurance Claim Number (HICN) and the MBI on your remittance advice, your vendor/clearinghouse is not using the MBI to submit your claims,” CMS says. The agency cautions Medicare practices to fix this issue before it’s too late. Reminder: You and your vendors may submit claims with HICNs through the transition period ending on Dec. 31, 2019. But, any claims sent after that date with the HICN instead of the MBI will be rejected, including vendor submissions, CMS warns.
