Inquiry Menu

The Inquiry Menu allows you to check the status of claims, including how to check for Additional Development Requests (ADRs), claims summary, Medicare check history, Part A payment totals, view inquiry screens to check the validity of diagnosis codes, revenue codes, HCPCS codes, and review reason code narratives. The menu options shown in bold text are those that you will use most often.

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).
