Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| 11127T | CA | Vision Therapy Optometrist primary |
| 11127T | CA | Low Vision Rehabilitation Optometrist |
This provider holds licence 11127T issued in CA. 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 Vision Therapy covers
Optometrists who specialize in vision therapy as a treatment process used to improve vision function. It includes a broad range of developmental and rehabilitative treatment programs individually prescribed to remediate specific sensory, motor and/or visual perceptual dysfunctions.

Full NPPES record
An NPI-2 identifies an organization — a clinic, hospital, group practice, laboratory, or supplier. Individual clinicians working there hold their own NPI-1 numbers separately, so a bill may reference both.

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 | 7 | 0 | 0 | 8 | 2 | 3 | 2 | 8 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 7 | 0 | 0 | 7 | 2 | 6 | 2 | 7 |
Sum = 57 · next multiple of 10 = 60 · 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.
