Coordination of Benefits: Parts A, B and HHH Crossover Claims Issue

CMS reported a system issue on April 8–15, 2021, that prevented Medicare part A, B (including durable medical equipment) and HHH crossover claims from crossing to certain supplemental payers. The issue was corrected on April 16, 2021. However, the system issue impacts claims finalizing through approximately April 25, for electronic claims and May 11, for paper claims.

Provider Action: If this issue affected your patients’ supplemental payer, bill them using your normal procedures, if Medicare claims weren’t crossed over. A link to the list of supplemental payers affected by this issue can be found in the April 29, 2021, CMS MLN Connects. The CMS link provides separate files for Part A, Part B, and DME supplemental payers that have been affected.
