What taxonomy code 222Q00000X means
222Q00000X is the National Uniform Claim Committee code for Developmental Therapist, in the grouping Respiratory, Developmental, Rehabilitative and Restorative Service Providers. 16,757 NPPES records list it as their primary taxonomy (file of Aug 9, 2026).
A Developmental Therapist is a person qualified by completion of an approved program in Developmental Therapy and where applicable credentialed by the state and practicing within the scope of the credential, or credentialed by completion of education experiences as approved by the state and practicing within the scope of that credential or, where state credentialing does not exist, certified by the Board of the Developmental Therapy Association. A developmental therapist evaluates children's global development in order to identify areas of developmental delay whether arising from physiological, neurological, or environmental factors, or a combination of factors; and designs, implements, and modifies therapeutic interventions for the child and the family to promote the child's acquisition of skills in a variety of developmental areas, including cognitive processes and social interaction in order to maximize functional independence and developmental homeostasis, and improve the quality of life at home and in the community; and provides consultation for the parents and other professionals working with the family on global development.
