Notes:

1. This REF segment is used to identify the location or Application System Number believed to contain the claim being inquired upon. For example, if a payer has multiple adjudication systems processing the same type of claim (e.g. professional or Institutional) and this Location Number points to the proper system that contains information about the claim being inquired upon. In Institutional claim situations where REF01 contains LU the inquirer must determine which REF segment (Bill Type or Medical Record Number) not to be included in the inquiry transaction.
2. The total number of REF segments in the 2200 loop cannot exceed 3.
