The Health Insurance Claim Number (HICN) to Medicare Beneficiary Identifier (MBI) CMS initiative will take another step forward in 2018. The transition in the MARx User Interface will begin in April, and, in preparation, a MARx HICN to MBI Crosswalk File will be generated for each Plan.

In March, PACE Plans will receive an “initial” HICN to MBI Crosswalk file which will include current membership back to 2006. A monthly file will be sent thereafter to capture any new enrollment changes.

If your organization is a Capstone client, you will receive further instructions about how to facilitate the required updates.   Regardless, we recommend a careful internal analysis of all vendors and systems that currently utilize your participants’ HICN to be sure a plan is in place to manage the transition.  These systems may include EMR, accounting, pharmacy or claims processing systems, for example.  

This file will only be provided once, so please be sure to download it and save it with your monthly records. 

Please refer to the CMS memo dated October 4, 2017, for more details.  Feel free to contact us at for any questions.
