• Appeals – You can use either the HICN or the MBI for claims appeals and related forms.
  • Claim status query – You can use either the HICN or MBI to check the status of a claim (276 transactions) if the earliest date of service on the claim is before January 1, 2020.  If you’re checking the status of a claim with a date of service on or after January 1, 2020, you have to use the MBI.
  • Span-date claims – You can use the HICN for 11X-Inpatient Hospital, 32X-Home Health (home health claims & Request for Anticipated Payments (RAPs)), and 41X-Religious Non-Medical Health Care Institution claims if the “From Date” is before the end of the transition period (12/31/2019).  You can submit claims received between April 1, 2018 and December 31, 2019 using the HICN or the MBI.  If a patient starts getting services in an inpatient hospital, home health, or religious non-medical health care institution before December 31, 2019, but stops getting those services after December 31, 2019, you may submit a claim using either the HICN or the MBI, even if you submit it after December 31, 2019.

Recognizing the New Medicare Card

Suspicious if the patient’s new card is legitimate? The new MBI is 11 characters long, with numbers and upper case letters. No special characters will be included. CMS cautions that if you submit the MBI in lower case, their system will convert the letters to upper case.

If your patient asks, the card doesn’t change their benefits and they should start using them as soon as they receive them. The effective date is the date the beneficiary was eligible for Medicare.
