UB04 Admission Hour Code 07: 07:00 AM - 07:59 AM

Introduction

Admission Hour Code 07 indicates that a patient was formally admitted to the facility between the hours of 07:00 AM and 07:59 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 commonly used for patients scheduled for early morning elective surgeries or those transitioning from an emergency department evaluation to inpatient status at the start of the first shift. It must reflect the actual time the physician's admission order was implemented rather than the time the patient arrived at the hospital gates.

Billing Impact

While the hour itself does not typically change the DRG assignment, accurate reporting is essential for medical necessity audits and calculating the total length of stay for per-diem reimbursement models.
