What Is POS 11 in Medical Billing?

POS 11 is a Place of Service code used in medical billing to indicate that healthcare services were performed in a physician’s office. The Centers for Medicare and Medicaid Services created POS codes to standardize claim submissions across healthcare systems.

When a provider submits a claim with POS 11, it tells the insurance payer that the patient received treatment in an office setting rather than a hospital, outpatient facility, or emergency department.

The office setting may include:

  • Private physician practices

  • Specialist clinics
