UB04 Admission Hour Code 13: 01:00 PM - 01:59 PM

Introduction

Admission Hour Code 13 represents a patient admission occurring between 01:00 PM and 01:59 PM. This code is reported in Field 13: Admission Hour to document the specific time of day the patient was formally admitted to the facility for inpatient or outpatient services.

Usage

This code is used by institutional providers, such as hospitals and skilled nursing facilities, to track patient volume and resource utilization during the early afternoon peak. It applies to all patients regardless of the source of admission, provided the clinical intake process was finalized during the 13th hour of the 24-hour clock.

Billing Impact

While the admission hour does not typically change the DRG assignment, accurate reporting is essential for medical necessity audits and to ensure the room and board charges align with the clinical timeline recorded in the patient's medical record.
