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 Respiratory Therapist, Registered covers
A Registered Respiratory Therapist (RRT) is an advanced therapist who has passed standardized written and clinical simulation examinations administered by the National Board for Respiratory Care (NBRC). In addition, to the certified therapist (CRT) entry level skills, RRTs have advanced education and training in patient assessment, in the development and modification of patient care plans, and in assuring the appropriate utilization of respiratory care resources. An RRT is a graduate of an associate or baccalaureate degree producing educational programs approved by the Commission on Accreditation of Allied Health Education Programs (CAAHEP) and where applicable, is licensed by the state and is practicing within the scope of that license. NUCC Health Care Provider Taxonomy, code 227900000X
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 | 0 | 0 | 3 | 5 | 1 | 6 | 1 | 5 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 1 | 1 | 3 | 1 | 1 |
Sum = 36 · next multiple of 10 = 40 · check digit = 4 · actual last digit = 4
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.
