What Independent Duty Medical Technicians covers
An Independent Duty Medical Technician (IDMT) is specially trained and educated to perform primary medical care, minor surgical services, and treatment of dental disorders for active duty military members in a variety of health care and non-health care settings worldwide under direct and indirect physician supervision. An IDMT may take medical histories, perform physical exams, order lab tests and x-rays, prescribe medications, and give immunizations. IDMTs work under the direct supervision of a physician preceptor when at home station and indirectly when assigned to a Mobile Aid Station, Mobile Medical Unit, remote site, or otherwise deployed specifically as an IDMT. An IDMT may be an experienced Aerospace Medical Service Technician who meets special task qualifications and is recommended for training by the Aerospace Medical Service Functional Manager at their Medical Treatment Facility. IDMTs maintain certification as Nationally Registered Emergency Medical Technicians and as Immunization Back-up Technicians. NUCC Health Care Provider Taxonomy, code 1710I1003X

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 | 8 | 9 | 7 | 1 | 9 | 5 | 2 |
|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Doubled? | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 | — | ×2 |
| Value | 8 | 0 | 8 | 8 | 0 | 2 | 6 | 7 | 9 | 5 | 1 | 9 | 5 | 4 |
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.
