Call the office to confirm.
Licensed in 2 states
This provider holds licences in 2 states: Montana and Washington. The practice address on file is in Bozeman, MT, 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 Pediatric Urology covers
Surgeons who can diagnose, treat, and manage children's urinary and genital problems. A pediatric urologist devotes a minimum of 50% of his or her practice to the urologic problems of infants, children, and adolescents. Pediatric urologists generally provide the following services: the evaluation and management of voiding disorders; vesicoureteral reflux, and urinary tract infections that require surgery; surgical reconstruction of the urinary tract (kidneys, ureters, and bladder) including genital abnormalities, hypospadias, and intersex conditions; surgery for groin conditions in childhood and adolescence (undescended testes, hydrocele/hernia, varicocele).

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 | 2 | 3 | 5 | 6 | 6 | 1 | 8 | 6 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 2 | 6 | 5 | 3 | 6 | 2 | 8 | 3 |
Sum = 61 · next multiple of 10 = 70 · check digit = 9 · actual last digit = 9
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.
