This Diagnostic and Treatment Centers (Clinics) page provides information about free-standing clinics in New York State. 

Under the statutory authority of Article 28, Section 3401 of the Public Health Law (PHL), and Title 10 of the New York Codes of Rules and Regulations (NYCRR), Section 405, providers who do not qualify or choose not to operate as private practices may be licensed by the State to operate free-standing clinics are also known as Diagnostic and Treatment Centers (Clinics).  These free-standing clinics are separately-owned and are not operated by a hospital.  By contrast, clinics that are owned and operated by a hospital are known as Hospital Extension Clinics.  Hospital Extension clinics can be identified by searching a specific hospital’s profile, clicking the “Overview” tab, and then selecting the “Extension Clinics” section.

Free-standing clinics include State licensed Diagnostic and Treatment Centers (D&TCs) that are also federally certified to provide specialized services, such as surgery or dialysis: 

  • end-stage renal disease dialysis clinics (ESRDs)
  • ambulatory surgery centers (ASCs)

Some of these State licensed D&TCs that provide primary care and medical services, as well as private practices, may also be federally designated by CMS as Federally Qualified Health Centers (FQHCs) or Rural Health Centers (RHCs). These facilities also provide general outpatient primary and medical care, but receive federal funding and must meet additional federal standards. They are required to serve underrepresented populations and geographic areas and allow patients to receive services regardless of their ability to pay. More information on these health centers, including a tool to find a health center near you, can be found at https://bphc.hrsa.gov/about/index.html.   

There are also D&TCs as well as private practices that are federally designated as Comprehensive Outpatient Rehabilitation Facility (CORFs) or Outpatient Physical Therapy Speech Pathology centers (OPT/SPs). These facilities provide specialized services to defined populations and must meet additional federal requirements. 

More information on CORFs can be found at this link.
