What Respiratory Therapist, Certified covers
A Certified Respiratory Therapist (CRT) is a an entry level therapist who has passed a standardized written examination administered by the National Board for Respiratory Care (NBRC). CRTs provide diagnostic testing, therapeutics, monitoring, rehabilitation, and education to patients with disorders of the cardiopulmonary system. They provide these respiratory care services in all health care facilities and in the home. A CRT is a graduate of an associate degree program approved by the Commission on Accreditation of Allied Health Educational Programs (CAAHEP) and where applicable, is licensed by the state and is practicing within the scope of the license.

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 | 3 | 9 | 0 | 4 | 0 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 0 | 0 | 3 | 6 | 9 | 0 | 4 | 0 |
Sum = 48 · next multiple of 10 = 50 · check digit = 2 · actual last digit = 2
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.
