  • All Form Locators (FL) correspond to official UB04 fields
  • Type of Bill code determines claim processing rules

  • 0111 — Inpatient Hospital, Original
  • 0131 — Outpatient Hospital
  • 0211 — Skilled Nursing Facility

Revenue codes (FL 42) categorize the type of service billed. Common codes:

  • 0250 — Pharmacy

  • 0360 — Operating room
  • 0370 — Anesthesia

Up to 25 ICD-10-CM diagnosis codes can be reported. The principal diagnosis (FL 67) is the condition chiefly responsible for the admission. Principal procedure (FL 74) uses ICD-10-PCS.
