UB04 Admission Hour Code 10: 10:00 AM - 10:59 AM

Introduction

Admission Hour Code 10 indicates that a patient was formally admitted to the facility between the hours of 10:00 AM and 10:59 AM. This code is reported in Field 13: Admission Hour to document the specific time of day the inpatient stay or outpatient observation began.

Usage

This code is used by acute care hospitals, skilled nursing facilities, and other institutional providers to track patient volume and resource allocation. It applies to all inpatient admissions, including those originating from the emergency department or scheduled surgical procedures that occur during the mid-morning window.

Billing Impact

While the hour itself does not typically change the DRG assignment, accurate reporting is essential for medical necessity audits and to ensure the admission time aligns with the clinical documentation and physician orders.
