  1. 1Identify the policy requiring the order.
  2. 2Check date, signature, item or service, quantity, and ordering provider.
  3. 3Compare claim ordering data with the record and enrollment source.

Resolution path

  1. 01Correct claim ordering data when the valid order was present.
  2. 02Submit the existing timely order through reopening or appeal when allowed.
  3. 03Do not create or backdate an order after the fact.
  4. 04Fix intake controls for future services.
