Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| 3144464 | CO | Environmental Modification Occupational… primary |
This provider holds licence 3144464 issued in CO. 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 Environmental Modification covers
Occupational therapy assistants provide environmental modifications under the supervision of an occupational therapist. OTAs develop and implement an individualized occupational therapy environmental modification plan that reflects the relevant contexts of the client and relevant others and maximizes current and future occupational performance, safety, and participation of the client. Clients receive environmental modification recommendations and interventions that enable them to meet occupational performance and participation goals and that have adequate flexibility to accommodate for their future needs. NUCC Health Care Provider Taxonomy, code 224ZE0001X
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 | 9 | 2 | 2 | 4 | 3 | 6 | 3 | 9 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 9 | 4 | 2 | 8 | 3 | 3 | 3 | 9 |
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.
