UB04 Admission Source Code B: Other Facility

Introduction

UB04 Code B, which represents an 'Other Facility' source, is a specific indicator used to identify the origin of a patient's admission. This code is used in Field 15: Admission Source. It serves as a catch-all designation when the patient is being transferred from a healthcare institution that does not fit the standard definitions of a hospital, skilled nursing facility, or clinic.

Usage

When billing with UB04 Code B, the provider is indicating that the patient was admitted to the current facility following a transfer from an 'Other' type of healthcare facility. This may include specialized treatment centers or non-standard residential medical facilities that are not otherwise classified in the Field 15 code set. Accurate usage is essential for tracking patient movement across the continuum of care and ensuring that the payer understands the patient's prior clinical setting, which can impact reimbursement and medical necessity determinations.

Related Codes

While Code B covers miscellaneous facilities, other codes exist in the parent field to specify more common origins, such as Code 1 (Non-Healthcare Facility Point of Origin), Code 2 (Clinic), or Code 4 (Transfer from a Hospital). Each code provides distinct data for the admission source requirement.
