Uniform Billing, version 04 (UB-04) Certification Practice Test

Procedures on inpatient UB-04 claims are described with ICD-10-PCS codes. These codes precisely identify the surgical or medical actions performed and are shown on the service lines of the claim, with each line linked to the related diagnosis through diagnosis pointers. This setup makes clear both what was done and the condition that prompted it. CPT codes aren’t used for inpatient hospital procedures on UB-04, and ICD-10-CM diagnoses describe conditions rather than the procedures themselves, while revenue codes indicate department or service area rather than the specific procedure.
