Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| 1604 | OK | Low Vision Occupational Therapist primary |
| 1604 | OK | Occupational Therapist |
This provider holds licence 1604 issued in OK. 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 Low Vision covers
Occupational therapists enable children and adults with visual impairment to engage in their chosen daily living activities safely and as independently as possible. This is accomplished by 1) teaching the person to use their remaining vision as efficiently as possible to complete activities; (2) modifying activities so that they can be completed with less vision; (3) training the person in use of adaptive equipment to compensate for vision loss, including high and low technology assistive devices; and (4) modifying the person's environment.

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 | 4 | 6 | 7 | 8 | 1 | 3 | 2 | 3 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 4 | 3 | 7 | 7 | 1 | 6 | 2 | 6 |
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.
