Definition
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.

Where 222Q00000X sits
- Group: Respiratory, Developmental, Rehabilitative and Restorative Service Providers — code 5 of 82 in the group
- Classification: Developmental Therapist 222Q00000X
Developmental Therapist has no specializations, so 222Q00000X is the only code for it. A provider may report more than one taxonomy code on an NPI but marks one as primary.
Medicare
222Q00000X has no entry in the CMS Medicare Provider and Supplier Taxonomy Crosswalk. That usually means Medicare does not enroll this kind of provider under its own specialty — the provider can still hold an NPI and use this code on claims to other payers.

The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
