Place of service 22 description refers to on-campus outpatient hospital services, a critical distinction that affects how claims are processed and reimbursed. This comprehensive guide will explore the intricacies of POS 22, compare it with other common codes like POS 11, and provide healthcare professionals with the knowledge needed to implement accurate billing practices.
Whether you’re a billing specialist, healthcare administrator, or medical provider, mastering the use of place of service 22 in medical billing will significantly impact your practice’s financial health and compliance with insurance requirements.
What is POS 22 in Medical Billing?
POS 22 is a two-digit place of service code that specifically identifies on-campus outpatient hospital services. This code is used when medical services are provided in a portion of a hospital’s main campus that provides diagnostic, therapeutic, and rehabilitation services to sick or injured persons who do not require hospitalization or institutionalization.
The place of service 22 description encompasses various outpatient services within the hospital setting, making it essential for accurate claim submission. Healthcare providers must understand that POS 22 comes into play when services are delivered in hospital outpatient departments, emergency rooms (for outpatient visits), and other on-campus hospital facilities where patients receive care without being admitted.
Key characteristics of POS 22 include:
• Services provided on the main hospital campus
• Outpatient care delivery (non-inpatient services)
• Diagnostic and therapeutic procedures • Emergency department visits for outpatient treatment
• Surgical and nonsurgical services to patients not requiring admission
• Laboratory and radiology services performed in hospital settings
Understanding the correct application of POS 22 is vital for billing teams as it directly impacts reimbursement rates. Insurance companies often have different payment structures for facility versus non-facility services, making the accurate use of pos code 22 crucial for maximizing revenue and ensuring compliance with billing regulations.

POS 11 vs POS 22: Key Differences in Medical Billing
The distinction between pos 11 in medical billing and pos 22 in medical billing represents one of the most important concepts in healthcare billing. While both codes relate to medical office settings, their applications differ significantly, affecting reimbursement and claim processing.
POS 11 refers to medical services provided in a physician’s office, which is a location other than a hospital, skilled nursing facility, military treatment facility, or other healthcare institution. This code applies to private practice settings, independent medical offices, and clinic environments that are not hospital-affiliated.
The fundamental differences between pos 11 and pos 22 include:
- Location Type: POS 11 represents independent medical offices, while POS 22 designates hospital outpatient departments
- Reimbursement Rates: Insurance companies typically pay different rates for facility (POS 22) versus non-facility (POS 11) services
- Overhead Considerations: Hospital-based services (POS 22) often receive higher reimbursement due to facility overhead costs
- Regulatory Requirements: Different compliance standards may apply depending on the place of service designation
Healthcare providers must carefully evaluate the actual location where services are provided to determine the correct pos code. Using pos 11 vs pos 22 incorrectly can result in claim denials, payment delays, or compliance issues with payers.
