- Taxonomy Description
- The chiropractic internist may serve as a primary care physician or may see patients referred from other providers for evaluation and co-management. Evaluation is focused on the early detection of functional, nutritional, and pathological disorders. A chiropractic internist utilizes the diagnostic instruments necessary for proper examination. In cases where laboratory examination is necessary, a chiropractic internist utilizes a recognized reference laboratory facility. A chiropractic internist may manage his or her own cases or may refer to another specialist when prudent to do so. The chiropractic internist utilizes documented natural therapies, therapeutic lifestyle changes, patient education and other resources to promote patient health and avoidance of disease.

NPI NPI Number Validation
How NPI Validation Works
The NPI validation process uses the ISO-standard Luhn algorithm, a mathematical "handshake", to ensure that a provider's 10-digit ID is authentic and free of common typing errors.
To verify the NPI 1902013642, we treat the final digit (2) as the Check Digit—the target answer we need to reach. The process begins by taking the first nine digits and adding a constant value of 24, which accounts for the "80840" prefix required for all U.S. health identifiers. We then double every other digit starting from the right and sum the individual digits of those results together. For this specific NPI, that total comes to 58. The final step is to find the difference between that total and the next multiple of ten (60 - 58 = 2).
Digit-by-digit view
Use the first nine digits for the calculation. Starting from the right, double every other digit. The last digit is the check digit and is not part of the calculation.
Step 1: Double every other digit from the right
Starting with the rightmost digit of the first nine digits, double every other value. If doubling creates a two-digit number, add those digits together.
Step 2: Add all digits plus the NPI constant
Add the transformed values, the unchanged digits, and the constant 24.
Step 3: Find the amount needed to reach the next multiple of 10
The next multiple of ten after 58 is 60. The difference is the calculated check digit.
