Credentials and Medicare
| Licence | State | Specialty |
|---|---|---|
| 23048 | CA | General Care Registered Respiratory… |
This provider holds licence 23048 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 Critical Care covers
Respiratory emergencies are commonplace in the treatment of critical care patients. Included in the assessment measurements conducted by the respiratory therapist in the critical care settings are arterial blood gas puncture and analysis, intrarterial monitoring, bedside measurements of lung mechanics, hemodynamic monitoring, and inspired and expired gas measurements. This is coupled with the initiation and management of mechanical ventilation patients. NUCC Health Care Provider Taxonomy, code 2279C0205X

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 | 7 | 9 | 8 | 2 | 6 | 5 | 9 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 6 | 5 | 9 | 7 | 2 | 3 | 5 | 9 |
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.
