Place of Service Codes (CMS1500 box 24b)

Identify of Service Codes are two-digit codes placed on wellness care professional 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 intendance manufacture.

This lawmaking ready is required for use in the implementation guide adopted equally the national standard for electronic manual of professional health intendance claims under the provisions of the Health Insurance Portability and Accountability Act of 1996 (HIPAA). HIPAA directed the Secretarial assistant of HHS to adopt national standards for electronic transactions. These standard transactions require all health plans and providers to utilise standard code sets to populate data elements in each transaction. The Transaction and Code Gear up Rule 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 past CMS as the lawmaking set to be used for describing sites of service in such claims. POS information is ofttimes needed to determine the acceptability of directly 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 on professional claims to specify the entity where service(s) were rendered. Check with individual payers (e.g., Medicare, Medicaid, other private insurance) for reimbursement policies regarding these codes. If yous would like to comment on a code(due south) or description(southward), please send your request to posinfo@cms.hhs.gov.

Code(southward) Identify of Service Name Place of Service Description Constructive Date
01 Chemist's shop A facility or location where drugs and other medically related items and services are sold, dispensed, or otherwise provided directly to patients. (effective 10/1/05) 2005-10-01

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.k., emergency shelters, individual or family unit shelters).

Special Considerations
Note that for the purposes of receiving durable medical equipment (DME), a homeless shelter is considered the beneficiary'south abode. Considering DME is payable in the beneficiary'southward dwelling house, the crosswalk for Homeless Shelter (code 04) to Part (lawmaking 11) that was mandated effective January one, 2003, may need to be adjusted or local policy adult and so that HCPCS codes for DME are covered when other conditions are met and the casher is in a homeless shelter. If desired, local contractors are permitted to work with their medical directors to make up one's mind a new crosswalk such every bit from Homeless Shelter (code 04) to Home (code 12) or Custodial Care Facility (code 33) for DME provided in a homeless shelter setting. If a local contractor is currently paying claims correctly, however, it is non necessary to change the current crosswalk.

05-08 Special Considerations
Medicare does non currently apply the POS codes designated for these settings. Follow the instructions y'all have received regarding how to process claims for services rendered in IHS and Tribal 638 settings. If you receive claims with these codes, yous must initially accept them in terms of HIPAA compliance. However, follow your "return every bit unprocessable" procedures after this initial compliance check. Follow your "return as unprocessable" procedures when you receive paper claims with these codes. (Annotation that while these codes became role of the National POS lawmaking set effective January 1, 2003, Medicare contractors received instructions regarding how to process claims with these codes effective October 1, 2003, so that Medicare could be HIPAA compliant past October 16, 2003).
09 Prison/ Correctional Facility A prison, jail, reformatory, piece of work farm, detention center, or any other similar facility maintained by either Federal, State or local regime for the purpose of solitude or rehabilitation of adult or juvenile criminal offenders.

Special Considerations
The addition of code 09 to the POS code gear up and Medicare claims processing reflects Medicare'south compliance with HIPAA laws and regulations. Local contractors must proceed to comply with CMS current policy that does not allow payment for Medicare services in a penal establishment in about cases. The addition of a POS code for a prison/correctional facility setting does not supersede this policy. (Run across Pub. 100-04, Medicare Claims Processing, section 10.4, chapter 1.)

Apply the non-facility charge per unit to payments for services designated as beingness furnished in POS code 15; utilize the appropriate facility or non-facility charge per unit for the POS code designated when a code other than the mobile unit lawmaking is indicated.

Other Special Considerations

Special Considerations for Services Furnished to Registered Inpatients

When a doctor/practitioner furnishes services to a registered inpatient, payment is made nether the PFS at the facility rate. To that end, a physician/practitioner/supplier furnishing services to a patient who is a registered inpatient, shall, at a minimum, report the inpatient infirmary POS code 21 irrespective of the setting where the patient actually receives the face-to-face encounter. In other words, reporting the inpatient hospital POS code 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 beneficiary is a registered inpatient, the appropriate inpatient POS code may be reported consequent with the code list annotated in this section (instead of POS 21). For example, a doc/practitioner may employ 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 Infirmary Departments

When a dr./practitioner furnishes services to an outpatient of a hospital, payment is made under the PFS at the facility rate. Physicians/practitioners who furnish services to a hospital outpatient, including in a hospital outpatient section (including in a provider-based section of that infirmary) or under arrangement to a hospital shall, at a minimum, report the outpatient infirmary POS code 22 irrespective of the setting where the patient actually receives the face-to-face up run into. 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 aware of the exact setting the beneficiary is a registered hospital outpatient, the appropriate outpatient facility POS code may be reported consequent with the lawmaking list annotated in this section (instead of POS 22). For case, physicians/practitioners may utilise POS code 23 for services furnished to a patient registered in the emergency room, POS 24 for patients registered in an ambulatory surgical eye, and POS 56 for patients registered in a psychiatric residential treatment center.

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