Wondering what that new N793 Remittance Advice Remark Code on your RAs means? With the Medicare Beneficiary Identifier set to be the only Medicare number accepted in less than four months, the Centers for Medicare & Medicaid Services is including on RAs “N793: ALERT - Starting January 1, 2020, Medicare will only accept claims submitted with the Medicare Beneficiary Identifier (MBI). Medicare will reject any claims submitted with the Health Insurance Claim Number (HICN) with a few exceptions,” CMS says in a message to providers. More information about the code and the switch to MBIs is at www.cms.gov/Outreach-and-Education/Medicare-Learning-Network-MLN/MLNMattersArticles/downloads/SE18006.pdf.
