What Radiology covers

Chiropractic radiology is a referral specialty that provides consultation services at the request of other qualified doctors. Chiropractic radiologists provide consultation in health care facilities (private offices, hospitals and teaching institutions) to meet the needs of referring doctors and their patients. The quality of the consultative services by the chiropractic radiologist in independent practice is reflected by the quality of their professional credentials. Chiropractic radiologists recommend, supervise, and interpret radiologic studies as well as advanced imaging procedures. They advise referring physicians on the necessity and appropriateness of radiologic services and whether to select or to avoid certain diagnostic or clinical procedures. In some instances the radiologist may act as a private practitioner. They may conduct research and apply diagnostic radiologic procedures and may be called upon to act as expert witnesses in matters of litigation.<br/>Chiropractic radiologists are also concerned with imaging technology including image production, demonstration of normal and abnormal anatomy, and the interaction of energy and matter. The advances in the technological facets of radiology are so rapid that only qualified radiologists can reasonably be expected to maintain the high level of proficiency required to supervise and interpret these procedures. The practice of radiology continuously involves the application of this technology to patient imaging and treatment. It is now well recognized that chiropractic radiology includes, but is not limited to, plain film radiography, fluoroscopy, tomography, ultrasonography, radioisotope imaging, computed tomography, digital radiography, and magnetic resonance imaging. Individual practices may vary by intent, licensure, and scope of practice laws. NUCC Health Care Provider Taxonomy, code 111NR0200X

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

1245608694 passes the NPI check digit test The final digit 4 matches the value computed from the first nine digits, so this is a well-formed NPI.
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 2 4 5 6 0 8 6 9
Doubled? ×2 ×2 ×2 ×2 ×2 ×2 ×2
Value 8 0 8 8 0 2 2 8 5 3 0 7 6 9

Sum = 66 · next multiple of 10 = 70 · 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.
