SSN-based HICN No Longer Accepted on MDS or Medicare Claims

This is a reminder that providers will no longer be able to submit a Social Security Number (SSN)-based Health Insurance Claim Number (HICN) or Railroad Retirement Board (RRB) number on the MDS in item A0600B or on the Medicare claim beginning January 1, 2020. Instead, the Medicare Beneficiary Identifier (MBI) must be used.

For additional details and resources regarding use of the MBI, please refer to the MLN Matters Article to learn how to get and use MBIs.
