Licensed in 2 states

This provider holds licences in 2 states: Connecticut and New York. The practice address on file is in White Plains, NY, but a licence in another state usually means they see patients there too — either at a second location or by telehealth. If the address above is far from you, it is worth calling to ask whether they practise closer to where you live.

What Social Worker covers

A social worker is a person who is qualified by a Social Work degree, and licensed, certified or registered by the state as a social worker to practice within the scope of that license. A social worker provides assistance and counseling to clients and their families who are dealing with social, emotional and environmental problems. Social work services may be rendered to individuals, families, groups, and the public. NUCC Health Care Provider Taxonomy, code 104100000X

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

1033616800 passes the NPI check digit test The final digit 0 matches the value computed from the first nine digits, so this is a well-formed NPI.
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 3 3 6 1 6 8 0
Doubled? ×2 ×2 ×2 ×2 ×2 ×2 ×2
Value 8 0 8 8 0 2 0 6 3 3 1 3 8 0

Sum = 50 · next multiple of 10 = 50 · check digit = 0 · actual last digit = 0

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.
