Introduction
Accurate service location reporting is essential in medical billing because it directly affects reimbursement, compliance, and claim approval. Insurance providers rely on standardized Place of Service (POS) codes to identify where healthcare services are delivered. One important code used in outpatient hospital billing is POS 19.
POS 19 in medical billing represents services performed in an off-campus outpatient hospital setting. Understanding this code helps healthcare providers ensure correct reimbursement, reduce claim denials, and maintain efficient revenue cycle management.
This article explains POS 19, when to use it, and why it plays an important role in healthcare billing operations.
What Is POS 19 in Medical Billing?
POS 19 is a standardized code used to indicate that healthcare services were delivered in an off-campus outpatient hospital facility. These facilities are owned or operated by a hospital but are located away from the main hospital campus.
Because off-campus outpatient facilities follow different reimbursement policies compared to physician offices or inpatient hospitals, accurate coding is essential for proper claim processing.
When to Use POS 19
Healthcare providers should use POS 19 when services are delivered in hospital-affiliated outpatient departments that are not located on the main hospital campus.
Common examples include:
- Hospital-owned outpatient clinics
- Diagnostic imaging centers affiliated with hospitals
- Off-campus specialty care facilities
- Outpatient surgical centers linked to hospitals
- Therapy services in hospital-owned outpatient sites
Correct service location reporting ensures accurate billing and compliance with insurance policies.

Correct POS reporting reduces errors and claim rejection risks.
Improves Revenue Cycle Efficiency
Clean claims lead to faster reimbursement and fewer administrative corrections.
Healthcare organizations that apply accurate POS coding maintain consistent financial performance and efficient billing operations.
