What is an occurrence code on a UB04?

An occurrence code on a UB-04 claim form is a standardized two-digit code used to report a specific, one-time event and its corresponding calendar date that affects how an institutional claim is processed, paid, or coordinated.

These codes are entered in Form Locators 31–34 of the UB-04 Claim Form Instructions and serve as a direct communication channel between healthcare providers and insurance payers.

Purpose and Function

  • Contextual Timing: They answer the "when" behind significant clinical or administrative milestones during a patient's treatment or billing cycle.
  • Mandatory Reporting: Payers and programs like Medicare require them to evaluate liability, coordination of benefits, and coverage timelines.

Common Examples of Occurrence Codes

  • 01: Auto accident date
  • 03: Accident/tort liability date
  • 04: Accident/employment-related date
  • 06: Crime-related injury date
  • 11: Onset of symptoms or illness date
