UB04 Admission Hour Code 06: 06:00 AM - 06:59 AM

Introduction

Admission Hour Code 06 indicates that a patient was formally admitted to the facility between 06:00 AM and 06:59 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. It is frequently seen in scheduled surgical admissions or early morning emergency department transfers where the patient is moved to an inpatient bed during the 6:00 AM hour.

Billing Impact

While the admission hour itself does not typically change the DRG assignment, it is essential for calculating the initial length of stay and ensuring the claim passes clinical necessity edits regarding the timing of physician orders.
