UB04 Type of Bill Code 0831: Specialty Facility - Ambulatory Surgery Center

Introduction

Type of Bill Code 0831 identifies a claim submitted by a specialty facility for outpatient surgical services. This code is reported in Field 4: Type of Bill.

Usage

This code is specifically used by freestanding Ambulatory Surgery Centers (ASCs) to bill for surgical procedures performed on an outpatient basis. The '831' sequence indicates a specialty facility (8), an ASC sub-type (3), and an admit-through-discharge claim frequency (1).

Billing Impact

Correct use of this code ensures the claim is processed under the ASC fee schedule rather than the standard hospital outpatient prospective payment system (OPPS).
