NGS Reminder: Medicare Beneficiary Identifier Change Days Away

Beginning January 1st 2020, providers will be required to use the new Medicare number, also known as the MBI, for all Medicare transactions. Information on the MBI transition is on our website by clicking Learn about MBI banner on

After January 1, 2020 the Medicare claims processing system will not process a claim without the MBI. National Government Services is providing a short key message or extended key message to assist associations in getting the word out; choose the best message for your members!

Not Using the MBI? Start Using the MBI Now!

Starting January 1, 2020 the Medicare Beneficiary Identifier (MBI) must be used in place of the HICN on claim submissions and eligibility transactions.

  • Medicare will reject claims you submit with the HICN, with few exceptions; and
  • Medicare will not give you eligibility information requested with the HICN.

Start using the MBI now!

CMS gave providers over a year to transition from using the HICN to using the MBI. During this transition period, claims submitted with valid MBIs have processed without incident. Therefore, if you have the MBI for your patient(s), please start using it now! Using the MBI during transition will ensure your claims are not rejected beginning January 2020.

If you do not have a patient’s MBI, use these resources:

Patient Intake/Registration At time of service, ask your patients or their caregiver for the new Medicare card.

Instant MBI Access Your Medicare patients can get their MBI, and print their own replacement card, by logging into their personal account on the web portal.

  • This is an excellent option for patients who do not want to give you their SSN.

NGSConnex MBI Look-up Tool All providers enrolled in our web portal can use their patient’s SSN, first and last name, and birthdate to retrieve their current MBI. (Then go on over to the Eligibility check to ensure their coverage is active during the time of service).

Medicare Remittance Advice During the transition period only, when a claim is submitted using your patient’s valid and active HICN, Medicare will display both the HICN and the MBI on every remittance advice.

If your Medicare patients have not received their new Medicare card tell them to:

  • Call 1-800-MEDICARE (1-800-633-4227). TTY users can call 1-877-486-2048. There may be a problem that needs to be correct, like updating the patient’s mailing address.
  • They may also access their account to get their MBI.
