Place of Service: A two-digit code used on health care professional claims to indicate the setting in which a service was provided.
Place of Service Codes are two-digit codes placed on health care professional claims to indicate the setting in which a service was provided. The Centers for Medicare & Medicaid Services (CMS) maintain POS codes used throughout the health care industry.
This code set is required for use in the implementation guide adopted as the national standard for electronic transmission of professional health care claims under the provisions of the Health Insurance Portability and Accountability Act of 1996 (HIPAA). HIPAA directed the Secretary of HHS to adopt national standards for electronic transactions. These standard transactions require all health plans and providers to use standard code sets to populate data elements in each transaction. The Transaction and Code Set Rule adopted the ASC X12N-837 Health Care Claim: Professional, volumes 1 and 2, version 4010, as the standard for electronic submission of professional claims. This standard names the POS code set currently maintained by CMS as the code set to be used for describing sites of service in such claims. POS information is often needed to determine the acceptability of direct billing of Medicare, Medicaid and private insurance services provided by a given provider.
Listed below are place of service codes and descriptions. These codes should be used to specify the entity where service(s) were rendered.

What place of service code (POS) should we bill for outpatient hospital?
Effective January 1, 2016, there will be two possible place of service codes to choose from for outpatient hospital settings: new place of service code 19 and revised place of service code 22.
Off Campus-Outpatient Hospital
A portion of an off-campus hospital provider based department which provides diagnostic, therapeutic (both surgical and nonsurgical), and rehabilitation services to sick or injured persons who do not require hospitalization or institutionalization.
On Campus-Outpatient Hospital
A portion of a hospital’s main campus which provides diagnostic, therapeutic (both surgical and nonsurgical), and rehabilitation services to sick or injured persons who do not require hospitalization or institutionalization.
Reporting outpatient hospital POS code 19 or 22 is a minimum requirement to trigger the facility payment amount under the Physician Fee Schedule (PFS) when services are provided to a registered outpatient. Therefore, you should use POS code 19 or POS code 22 when you furnish services to a hospital outpatient regardless of where the face-to-face encounter occurs.
The payment policies that currently apply to POS 22 will continue to apply to this POS, and will now also apply to POS 19 unless otherwise stated in Change Request (CR) 9231.
What place of service (POS) do I use when reading a test from a remote location?
Effective April 1, 2013, CR 7631 establishes that for all services – with two exceptions – paid under the MFPS, the POS code to be used by the physician and other supplier will be assigned as the same setting in which the beneficiary received the face-to-face service. Because a face-to-face encounter with a physician/practitioner is required for nearly all services paid under the MPFS and anesthesia services, this rule will apply to the overwhelming majority of MPFS services. In cases where the face-to-face requirement is obviated such as those when a physician/practitioner provides the PC/interpretation of a diagnostic test, from a distant site, the POS code assigned by the physician/practitioner will be the setting in which the beneficiary received the TC of the service.
There are two exceptions to this face-to-face provision/rule in which the physician always uses the POS code where the beneficiary is receiving care as a hospital inpatient or an outpatient of a hospital, regardless of where the beneficiary encounters the face-to-face service. The correct POS code assignment will be for that setting in which the beneficiary is receiving inpatient or outpatient care from a hospital, including the inpatient hospital (POS code 21) or the outpatient hospital (POS code 19 or 22). The Medicare Claims Processing Manual already requires this for physician services (and for certain independent laboratory services) provided to beneficiaries in an inpatient hospital and CR 7631 clarifies this exception and extends it to beneficiaries in an outpatient hospital.
