What Prevention Professional covers
Prevention Professionals work in programs aimed to address specific patient needs, such as suicide prevention, violence prevention, alcohol avoidance, drug avoidance, and tobacco prevention. The goal of the program is to reduce the risk of relapse, injury, or re-injury of the patient. Prevention Professionals work in a variety of settings and provide appropriate case management, mediation, referral, and mentorship services. Individuals complete prevention professionals training for the population of patients with whom they work. NUCC Health Care Provider Taxonomy, code 405300000X

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 | 1 | 3 | 4 | 9 | 5 | 7 | 1 | 2 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 1 | 6 | 4 | 9 | 5 | 5 | 1 | 4 |
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.
