UB04 Admission Hour Code 02: 02:00 AM - 02:59 AM

Introduction

Admission Hour Code 02 indicates that a patient was formally admitted to the facility between the hours of 02:00 AM and 02:59 AM. This code is reported in Field 13: Admission Hour.

Usage

This code is used by institutional providers to document the specific hour of a patient's arrival or the start of inpatient care during the early morning period. It is essential for tracking hospital census data and verifying the duration of stay for patients admitted through the emergency department or via direct transfer during the second hour of the day.

Billing Impact

While the hour itself does not typically change the DRG assignment, accurate reporting is required for claim validation and can impact the calculation of room and board charges for the initial day of service.
