Licences are recorded in 3 states: MN, NC, UT. Providers licensed in several states often practise near a state border or deliver telehealth across state lines.
This NPI does not appear in the PECOS Medicare enrolment file. Providers who do not bill Medicare — or who bill only through a group's enrolment — will not appear here. It is not a sign of any problem with the registration.
Licensed in 3 states
This provider holds licences in 3 states: Minnesota, North Carolina and Utah. Multi-state licensure often means the provider works near a state border, covers more than one office, or delivers care by telehealth. If the address above is far from you, it is worth calling to ask whether they practise closer to where you live.
Licence numbers are self-reported to NPPES at registration. They do not confirm a licence is currently active, in good standing, or valid for the specialty shown — only the state board can tell you that, which is why we link to each one.
What Pulmonary Function Technologist covers
An individual who is trained and qualified to perform pulmonary diagnostic tests. In the course of conducting these tests, the Pulmonary Function Technologist is able to setup, calibrate, maintain, and ensure the quality assurance of the pulmonary function testing equipment. In the laboratory, clinical or patient care setting the technologist instructs patients, elicits cooperation, performs procedures, monitors patient response, and evaluates patient performance. Tests results are calculated, compared with predicted normal ranges, and evaluated for reliability. The technologist collects clinical history data and evaluates the clinical implications of the test results. NUCC Health Care Provider Taxonomy, code 2278P1006X

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 | 6 | 5 | 9 | 5 | 7 | 7 | 7 | 0 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 6 | 1 | 9 | 1 | 7 | 5 | 7 | 0 |
Sum = 62 · next multiple of 10 = 70 · check digit = 8 · actual last digit = 8
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.
