Starting Dec. 9, providers will need to submit all 837 claim transactions to Change Healthcare instead of Availity. This is one of the final stages of the transition back to PCS/Change Healthcare. From now until Dec. 9, providers can submit claims to Hennepin Health through either Change Healthcare or Availity. After Dec. 9, Hennepin Health will no longer accept 837 claim transactions through Availity. Hennepin Health recently communicated about the transition back to PCS/Change Healthcare in this provider bulletin.
