Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| 176065 | NY | Personal Emergency Response Attendant primary |
This provider holds licence 176065 issued in NY. A licence number in NPPES reflects what was filed at registration — it does not confirm the licence is still active today.
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 Personal Emergency Response Attendant covers
Individuals that are specially trained to assist patients living at home with urgent/emergent situations. These individuals must be able to perform CPR and basic first aid and have sufficient counseling skills to allay fears and assist in working through processes necessary to resolve the crisis. Functions may include transportation to various facilities and businesses, contacting agencies to initiate remediation service or providing reassurance. NUCC Health Care Provider Taxonomy, code 146D00000X
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 | 1 | 9 | 4 | 8 | 9 | 3 | 9 | 5 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 1 | 9 | 4 | 7 | 9 | 6 | 9 | 1 |
Sum = 72 · next multiple of 10 = 80 · 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.
