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.

What Genetic Counselor, MS covers
A masters trained health care provider who collects and interprets genetic family histories; assesses the risk of disease occurrence or recurrence; identifies interventions to manage or ameliorate disease risk; educates about inheritance, testing, management, prevention, ethical issues, resources, and research; and counsels to promote informed choices and adaptation. Certification was established in 1993 by the American Board of Genetic Counseling and prior to that by the American Board of Medical Genetics. Requirements for experience, licensure, and job responsibilities vary among the states. NUCC Health Care Provider Taxonomy, code 170300000X
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 | 5 | 7 | 8 | 3 | 8 | 1 | 0 | 4 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 5 | 5 | 8 | 6 | 8 | 2 | 0 | 8 |
Sum = 68 · next multiple of 10 = 70 · 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.
