Credentials and Medicare
NPPES does not list a state licence number for this record. That is not unusual — organizations and some provider types are not required to file one. Verify current licensure with the relevant state board before care.
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.
What Specialist/Technologist, Pathology covers
(1) An individual educated and trained in clinical chemistry, microbiology or other biological sciences; and in gathering data on the blood, tissues, and fluids in the human body. Tests and procedures performed or supervised center on major areas of hematology, microbiology, immunohematology, immunology, clinical chemistry and urinalysis. Education and certification requires the equivalent of an associate degree and alternative combinations of accredited training and experience. (2) A specially trained individual who works under the direction of a pathologist, other physician, or scientist, and performs specialized chemical, microscopic, and bacteriological tests of human blood, tissue, and fluids. Also known as medical technologists, they perform and supervise tests and procedures in clinical chemistry, immunology, serology, bacteriology, hematology, parasitology, mycology, urinalysis, and blood banking. The work requires the correlation of test results with other data, interpretation of test findings, and exercise of independent judgment. The minimum educational requirement (for one of several certification programs in medical technology) is a baccalaureate degree with appropriate science course requirements, plus a twelve-month, structured, AMA approved medical technology program and an examination; or a baccalaureate degree with appropriate science course requirements and experience. NUCC Health Care Provider Taxonomy, code 246Q00000X
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.

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 | 7 | 4 | 4 | 0 | 3 | 7 | 6 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 1 | 5 | 4 | 8 | 0 | 6 | 7 | 3 |
Sum = 60 · next multiple of 10 = 60 · check digit = 0 · actual last digit = 0
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.
