  • Review the Provider Contacts List to make sure you are calling the right number for your question.
  • If you identify an error or unexpected denial on your paper Remittance Advice or 835 transaction from OHA, research the problem from your end.

  • Review OHA’s common billing errors and how to resolve them.
