About Status/Location Codes

  • As billing transactions process in FISS, they move through various stages of the system. These stages are identified by status/location codes and provide information about what’s happening to the claim.
  • There are six status codes that are represented in FISS by one letter (e.g., P for Paid).
  • Locations further define what is happening to a billing transaction in a particular status. Locations are 5-character positions that follow the status code (e.g., P B9997; where P is the status and B9997 is the location).

Monitoring your Billing Transactions

  • Check your billing transactions at least once a week
  • You may need to take additional action after you have submitted them
  • Some claims may be returned to the provider (RTPd) due to missing, incorrect, or incomplete information
  • You will need to access your billing transactions in the Return to Provider (RTP) to make the necessary corrections.
  • When a claim is corrected from the RTP file, it will receive a new receipt date.
  • When you sign on to FISS, you should:
    • Correct any billing transactions that are in your RTP file.
    • Respond to any Additional Development Requests (ADRs).
