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 Feeding, Eating & Swallowing covers
Occupational therapists provide interventions to clients of all ages with feeding, eating and swallowing difficulties. Occupational therapists provide comprehensive rehabilitative, habilitative, and palliative dysphagia care, which includes collaborating with clients to provide individualized compensatory swallowing strategies, modified diet textures, adapted mealtime environments, enhanced feeding skills, preparatory exercises and positioning to clients, reinforcement of mealtime strategies to enhance and improve swallowing skills, and training to caregivers to enhance eating and feeding performance. Occupational therapists provide screening and in-depth clinical assessment which may include instrumental dysphagia assessments including videofluroscopy. NUCC Health Care Provider Taxonomy, code 225XF0002X
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 | 6 | 5 | 9 | 9 | 2 | 1 | 6 | 3 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 6 | 1 | 9 | 9 | 2 | 2 | 6 | 6 |
Sum = 67 · next multiple of 10 = 70 · check digit = 3 · actual last digit = 3
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.
