Credentials and Medicare

|---|---|---|

What Developmental Therapist covers
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. NUCC Health Care Provider Taxonomy, code 222Q00000X
The taxonomy records how the provider classifies their own practice. It does not confirm which conditions they currently treat, whether they are accepting new patients, or which insurance they take — call the office for that.
Full NPPES record
An NPI-1 identifies a single person. It stays with the clinician for life, even if they move practice or change state, which is why the address on file can lag behind where they actually work today.

Number check
How the check works, step by step
Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.
| Digit | 8 | 0 | 8 | 4 | 0 | 1 | 0 | 0 | 3 | 2 | 9 | 1 | 6 | 2 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 4 | 9 | 2 | 6 | 4 |
Sum = 54 · next multiple of 10 = 60 · check digit = 6 · actual last digit = 6
A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
