Medicare Crossover List from May 6th Alert

May 6th, 2021

A Message from CMS - April 30, 2021

This information has been communicated to us by a vendor: CMS

Coordination of Benefits: Parts A & B Crossover Claims Issue

Due to an April 8-15 systems issue, Medicare didn’t send Part A and Part B (including Durable Medical Equipment (DME)) crossover claims to some supplemental payers. We corrected this issue on April 16; however, it impacts claims finalized through approximately:

  • April 25 (electronic claims)
  • May 11 (paper claims)


If this issue affected your patients’ supplemental payer (listed below), bill them using your normal procedures (if Medicare claims weren’t crossed over).

Claim Type:  Part B (837 professional non-DME MAC claims)
