Licensed in 6 states

This provider holds licences in 6 states: District of Columbia, Florida, Maryland, Nebraska, Texas and Virginia.

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

1144429077 passes the NPI check digit test The final digit 7 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 1 4 4 4 2 9 0 7
Doubled? ×2 ×2 ×2 ×2 ×2 ×2 ×2
Value 8 0 8 8 0 2 1 8 4 8 2 9 0 5

Sum = 63 · next multiple of 10 = 70 · check digit = 7 · actual last digit = 7

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.
