Programs that utilize one or a combination of diagnostic tools to test large groups of people who are assumed to be well for the presence of a particular disease or condition or for certain risk factors that are known to be associated with that disease or condition; or which conduct in-depth tests to establish the cause and nature of an individual's presenting illness. The purpose of screening is to identify people who have a potential problem and refer them for early diagnosis and treatment and, where possible, to provide preventive measures. Early identification is particularly important when dealing with conditions that are more difficult to treat when fully developed. The purpose of more in-depth diagnostic work is to establish a logical basis for ongoing treatment.
Programs that provide equipment, information, social services or other forms of support which supplement the treatment or habilitation of people who have illnesses, injuries or disabilities or facilitate their ability to function. Included are blood banking services and other anatomical specimen banks, assistive technology equipment and services, medical equipment and supplies, health care referrals, health insurance, pharmacy services, prescription medication support services and health education information which may be instrumental in the prevention of illnesses, injuries or disabilities prior to their occurrence, teach people to provide emergency first aid or help people make informed decisions about health care.
Programs that provide rehabilitation and/or habilitation services. Rehabilitation services involve a combination of treatment and education services which are designed to restore maximum functioning, a sense of well-being and a personally satisfying level of independence for individuals who have temporary or permanent disabilities. Habilitation services involve a combination of treatment and education services which are designed to either increase or maintain the physical, intellectual, emotional, and social functioning of individuals who have not reached age-appropriate developmental milestones.
Programs that offer diagnostic and treatment services that are provided by physicians who have special training and expertise in a clinical area of practice which focuses on a specific age group (e.g., geriatrics, pediatrics), an organ or organ system of the body (e.g., internal medicine, obstetrics/gynecology) or on complex scientific techniques developed to diagnose or treat certain types of disorders (e.g., nuclear medicine, radiology).
