Completing the UB-04 Claim Form Practice Exam 2026 - Free UB-04 Claim Form Practice Questions and Study Guide

Type of Bill codes on the UB-04 tell the payer the setting and the nature of the stay. For hospital inpatient encounters, the standard code is 0111. The first two digits identify the setting as hospital, and the last two digits indicate that this is an inpatient stay (as opposed to outpatient, clinic, or other billing scenarios). Therefore, 0111 uniquely matches a hospital inpatient claim, while the other four-digit codes represent different billing situations and do not denote an inpatient hospital encounter.
