FISS/DDE Provider Online Guide: Chapter I

Document Control Number


The FISS DDE Provider Online System refers to the claim control number as a DCN. The DCN provides a reference number for the control and monitoring of each claim. To differentiate between claims for the beneficiary, the system creates a unique control number. The DCN may also be referred to as the ICN.

The DCN is a 23-position number assigned by the system. It is the identifying code for each claim and serves the following functions:

  • Completes the ‘key’ to automate the finding of claims on the claim file (with beneficiary identification number)
  • Contains a Year (position 2‑3) and Julian date (position 4‑6) which provides the system with the claim's entry date
  • Contains an Origin code (position 14) which identifies the claim's mode of submission

Points to Remember

  • You are not able to search for claims in the online system using the DCN
  • When an adjustment or cancel is submitted online, the system automatically plugs in the appropriate DCN of the original claim
  • The DCN is referenced on the following documents:
    • Remittance advice (shows as ICN due to standardization of the remittance advice)
    • ADR
  • The DCN is not referenced on the 201 Pend Report (claim status)

Every DCN tells a story; the following is an example DCN and an explanation of each position.

DCN = 21800700814502ILA
