Place of Service Codes (CMS1500 box 24b)

Place of Service Codes are two-digit codes placed on health care professional person claims to signal 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 lawmaking fix is required for use in the implementation guide adopted as the national standard for electronic manual of professional wellness intendance claims nether 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 Dominion adopted the ASC X12N-837 Health Care Claim: Professional person, 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 straight billing of Medicare, Medicaid and private insurance services provided past a given provider.

Lawmaking(due south) Place of Service Name Place of Service Description Effective Engagement

02 Telehealth Provided Other than in Patient'southward Home The location where wellness services and health related services are provided or received, through telecommunication technology. Patient is not located in their home when receiving wellness services or health related services through telecommunication technology.
(Description change effective Jan ane, 2022, and applicable for Medicare April 1, 2022.)

Special Considerations
Note that while the modification of POS Code 02 and the creation of POS Lawmaking 10 are constructive in the National POS code set up effective January 1, 2022, Medicare contractors received instructions regarding how to process claims with these codes starting April iv, 2022, so that Medicare would align with existing Telehealth claims processing policy, as well equally be considered HIPAA compliant.

03 School A facility whose primary purpose is education. 2003-01-01
04 Homeless Shelter A facility or location whose primary purpose is to provide temporary housing to homeless individuals (eastward.g., emergency shelters, individual or family shelters).

Special Considerations
Annotation that for the purposes of receiving durable medical equipment (DME), a homeless shelter is considered the beneficiary's abode. Because DME is payable in the beneficiary's home, the crosswalk for Homeless Shelter (lawmaking 04) to Office (code eleven) that was mandated effective January 1, 2003, may need to be adjusted or local policy adult so that HCPCS codes for DME are covered when other atmospheric condition are met and the beneficiary is in a homeless shelter. If desired, local contractors are permitted to work with their medical directors to determine a new crosswalk such as from Homeless Shelter (code 04) to Dwelling (lawmaking 12) or Custodial Intendance Facility (code 33) for DME provided in a homeless shelter setting. If a local contractor is currently paying claims correctly, however, it is not necessary to change the electric current crosswalk.

05 Indian Health Service Gratis-standing Facility A facility or location, owned and operated by the Indian Health Service, which provides diagnostic, therapeutic (surgical and non-surgical), and rehabilitation services to American Indians and Alaska Natives who do non require hospitalization.  (See 05-08 Special Considerations below.) 2003-01-01

05-08 Special Considerations
Medicare does not currently use the POS codes designated for these settings. Follow the instructions you lot have received regarding how to procedure claims for services rendered in IHS and Tribal 638 settings. If you receive claims with these codes, you must initially accept them in terms of HIPAA compliance. However, follow your "return equally unprocessable" procedures after this initial compliance check. Follow your "return as unprocessable" procedures when you receive paper claims with these codes. (Note that while these codes became part of the National POS code gear up effective January 1, 2003, Medicare contractors received instructions regarding how to process claims with these codes effective October i, 2003, so that Medicare could be HIPAA compliant by October 16, 2003).
09 Prison/ Correctional Facility A prison, jail, reformatory, work farm, detention eye, or any other similar facility maintained by either Federal, State or local authorities for the purpose of confinement or rehabilitation of adult or juvenile criminal offenders.

Special Considerations
The addition of lawmaking 09 to the POS code ready and Medicare claims processing reflects Medicare's compliance with HIPAA laws and regulations. Local contractors must continue to comply with CMS current policy that does not allow payment for Medicare services in a penal institution in most cases. The addition of a POS lawmaking for a prison/correctional facility setting does non supersede this policy. (Run into Pub. 100-04, Medicare Claims Processing, section x.4, chapter one.)

(This lawmaking is effective January 1, 2022, and available to Medicare April i, 2022.)

Special Considerations
Note that while the modification of POS Code 02 and the creation of POS Code 10 are effective in the National POS code set effective Jan 1, 2022, Medicare contractors received instructions regarding how to process claims with these codes starting April 4, 2022, so that Medicare would align with existing Telehealth claims processing policy, as well as be considered HIPAA compliant.

Nevertheless, if the mobile unit is not serving an entity which could exist described past an existing POS code, the providers are to apply the Mobile Unit POS code xv. Apply the non-facility rate to payments for services designated as existence furnished in POS code 15; employ the appropriate facility or non-facility rate for the POS code designated when a code other than the mobile unit of measurement code is indicated.

A medico or practitioner'southward office, even if mobile, qualifies to serve as a telehealth originating site.

Other Special Considerations

Special Considerations for Services Furnished to Registered Inpatients

When a physician/practitioner furnishes services to a registered inpatient, payment is made under the PFS at the facility charge per unit. To that stop, a physician/practitioner/supplier furnishing services to a patient who is a registered inpatient, shall, at a minimum, report the inpatient hospital POS code 21 irrespective of the setting where the patient actually receives the face-to-face run across. In other words, reporting the inpatient hospital POS lawmaking 21 is a minimum requirement for purposes of triggering the facility payment under the PFS when services are provided to a registered inpatient. If the physician/practitioner is aware of the exact setting the casher is a registered inpatient, the appropriate inpatient POS code may be reported consistent with the lawmaking list annotated in this section (instead of POS 21). For example, a physician/practitioner may utilise POS 31, for a patient in a SNF receiving inpatient skilled nursing intendance, POS 51, for a patient registered in a Psychiatric Inpatient Facility, and POS 61 for patients registered in a Comprehensive Inpatient Rehabilitation Facility.


Special Considerations for Outpatient Hospital Departments

When a physician/practitioner furnishes services to an outpatient of a hospital, payment is made under the PFS at the facility charge per unit. Physicians/practitioners who furnish services to a hospital outpatient, including in a hospital outpatient section (including in a provider-based department of that hospital) or under system to a infirmary shall, at a minimum, report the outpatient infirmary POS code 22 irrespective of the setting where the patient actually receives the face up-to-face encounter. In other words, reporting the outpatient hospital POS lawmaking 22 is a minimum requirement for purposes of triggering the facility payment amount under the PFS when services are provided to a registered outpatient. If the physician/practitioner is enlightened of the exact setting the beneficiary is a registered hospital outpatient, the appropriate outpatient facility POS lawmaking may be reported consequent with the lawmaking listing annotated in this department (instead of POS 22). For instance, physicians/practitioners may use POS code 23 for services furnished to a patient registered in the emergency room, POS 24 for patients registered in an ambulatory surgical centre, and POS 56 for patients registered in a psychiatric residential treatment middle.

NOTE: Physicians/practitioners who perform services in a infirmary outpatient section shall utilize, at a minimum, POS code 22 (Outpatient Hospital). Code 22 (or other appropriate outpatient department POS lawmaking equally described above) shall be used unless the physician maintains separate office infinite in the hospital or on the hospital campus and that dr. office space is not considered a provider-based department of the hospital as divers in 42. C.F.R. 413.65. Physicians shall use POS lawmaking xi (office) when services are performed in a separately maintained physician part space in the hospital or on the hospital campus and that physician office infinite is not considered a provider-based department of the hospital. Use of POS lawmaking 11(role) in the hospital outpatient department or on hospital campus is subject to the physician self-referral provisions ready forth in 42 C.F.R 411.353 through 411.357.
