What Pediatric Radiology covers
A radiologist who is proficient in all forms of diagnostic imaging as it pertains to the treatment of diseases in the newborn, infant, child and adolescent. This specialist has knowledge of both imaging and interventional procedures related to the care and management of diseases of children. A pediatric radiologist must be highly knowledgeable of all organ systems as they relate to growth and development, congenital malformations, diseases peculiar to infants and children and diseases that begin in childhood but cause substantial residual impairment in adulthood. NUCC Health Care Provider Taxonomy, code 2085P0229X
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.

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 | 7 | 0 | 0 | 8 | 8 | 0 | 5 | 4 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 7 | 0 | 0 | 7 | 8 | 0 | 5 | 8 |
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.
