FISS Narrative
A revenue code is invalid for the type of bill or it is not a valid revenue code for Medicare claims.

Explanation and suggestion:

  • This reason code occurs when a provider is trying to bill a revenue code on the wrong type of bill (TOB)
  • The most frequent example is revenue code 403 (screening mammography) on TOB 13x
  • Medicare guidelines require screening mammography services to be submitted on TOB 14x
  • The revenue code being billed may be checked for the correct TOB on the FISS revenue code file
  • Please correct and resubmit/rekey
  • Hard copy submitters resubmit RTP report with correction
