Transition Period

A transition period will begin no earlier than April 1, 2018 and run through Dec. 31, 2019. During the transition period, you can use either the new Medicare Beneficiary Identifier (MBI) or the old Medicare Health Insurance Claim Number (HICN).

Starting Jan. 1, 2020, you must use MBIs on claims regardless of the date of service.

CMS Educational Efforts

To prepare the health care industry for this change, CMS provided extensive outreach to the provider community and will continue to do so throughout the transition period. CMS holds regular Open Door Forum teleconferences to help you prepare your systems and business processes for a successful transition.
CMS also initiated extensive education and outreach to Medicare beneficiaries and their agents to help them prepare and understand the change in Medicare cards and numbers. CMS produced flyers, posters, tear-offs and conference cards in multiple languages to assist providers when talking to their patients with Medicare about the new Medicare cards.
