UB04 Admission Hour Code 19: 07:00 PM - 07:59 PM

Introduction

Admission Hour Code 19 indicates that a patient was formally admitted to the facility between the hours of 07:00 PM and 07:59 PM. This code is reported in Field 13: Admission Hour to document the specific time of day the physician's admission order was processed.

Usage

This code is used by institutional providers, such as acute care hospitals and skilled nursing facilities, to track the start of an inpatient stay or outpatient observation period. It is applied when the clinical documentation shows the patient's admission status began during the nineteenth hour of the day using a 24-hour clock cycle.

Billing Impact

While the admission hour does not directly determine the DRG assignment, it is essential for calculating the correct number of covered days and ensuring the claim passes clinical consistency edits for room and board charges.
