UB04 Type of Bill Code 0131: Hospital Outpatient - Admit through Discharge Claim

Introduction

Type of Bill Code 0131 represents a Hospital Outpatient Admit through Discharge Claim. This code is reported in Field 4: Type of Bill to identify the specific type of facility and the frequency of the billing cycle for outpatient services.

Usage

This code is utilized when a patient receives outpatient services at a hospital and the entire course of treatment is captured on a single claim. It signifies that the bill covers the period from the initial admission or start of service through the final discharge, rather than being a partial or interim bill.

Billing Impact

Using this code ensures the payer processes the claim as a complete episode of care, preventing payment delays associated with missing interim sequences and ensuring accurate outpatient prospective payment system (OPPS) reimbursement.
