Provider Claims Must Include Medicare Beneficiary Identifiers by Jan. 1, 2020

This post has been archived and contains information that may be out of date.

CHA reminds members that beginning Jan. 1, 2020, all provider claims must be submitted with Medicare beneficiary identifiers (MBIs) regardless of the date the service was performed. Claims submitted with Social Security number-based health insurance claim numbers will be rejected, with a few exceptions.

Based on recent data shared with CHA by Noridian Healthcare Solutions and the Centers for Medicare & Medicaid Services, California hospitals are currently reporting the new MBI at around the national average of 66% of claims.

Noridian Healthcare Solutions offers several resources on MBIs, and CHA encourages members to review the following information before the transition period ends on Dec. 31:

• Monthly Webinar
• Tutorials to compliment webinar content
  • MBI Overview
  • MBI Retrieval and Resources
• MBI Webpage
• Noridian Medicare Portal (NMP) MBI Look-up Tool
  • NMP’s MBI Look-up Tool Tutorial
• Directions on obtaining an MBI when a health insurance claim number was submitted
