What Podiatrist covers
A podiatrist is a person qualified by a Doctor of Podiatric Medicine (D.P.M.) degree, licensed by the state, and practicing within the scope of that license. Podiatrists diagnose and treat foot diseases and deformities. They perform medical, surgical and other operative procedures, prescribe corrective devices and prescribe and administer drugs and physical therapy. NUCC Health Care Provider Taxonomy, code 213E00000X
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 | 3 | 0 | 6 | 8 | 2 | 0 | 4 | 0 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 3 | 0 | 6 | 7 | 2 | 0 | 4 | 0 |
Sum = 48 · next multiple of 10 = 50 · check digit = 2 · actual last digit = 2
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.
