CMS has reported that more then two thirds of Medicare claims now use the MBI instead of the HIC number. All claims must use the MBI by the end of 2019. Medicare has published two handy references to help:
- New MBI: Get It, Use It, including three ways to obtain an MBI – https://www.cms.gov/Outreach-and-Education/Medicare-Learning-Network-MLN/MLNmattersArticles/downloads/SE18006.pdf.
- Understanding the MBI, a one-page chart for your wall or desktop clarifying how the MBI is coded – https://www.cms.gov/Outreach-and-Education/Medicare-Learning-Network-MLN/MLNProducts/Downloads/UnderstandingTheMBI-MLN3657604.pdf.
