Specialty - Primary Taxonomy

The NPI enumerator requires providers to submit at least one taxonomy code. A taxonomy code is a unique 10-character code that describes the healthcare provider type, classification, and the area of specialization. There could be only one primary taxonomy code per NPI record. For individual NPIs the license data is associated to the taxonomy code.

Classification: Dietetic Technician, Registered
Taxonomy Code: 136A00000X
Type: Dietary & Nutritional Service Providers
License No.: 86290324
License State: AZ
Taxonomy Description: A Dietetic Technician, Registered (DTR)/Nutrition and Dietetics Technician, Registered (NDTR) is an individual holding a nationally protected title issued by the Commission on Dietetic Registration (CDR) to qualified individuals who obtain an associate's degree or higher and successfully complete a sliding set of academic, examination, and practice requirements accredited by the Accreditation Council for Education in Nutrition and Dietetics (ACEND) or established by CDR, the nature of which are dependent upon the level of academic degree obtained. The scope of practice of the NDTR focuses on food, nutrition, and dietetics practice, as well as related services. NDTRs work under the supervision of a Registered Dietitian Nutritionist (RDN) when in direct patient/client nutrition care, and may work independently in providing general nutrition education to healthy populations. Patient/client populations include individuals receiving individualized care who have medical conditions or diseases, as well as at-risk individuals receiving personalized nutrition guidance as part of preventive health care.

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 1811500952, 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 48. The final step is to find the difference between that total and the next multiple of ten (50 - 48 = 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.

Regular digit Doubled digit Check digit

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.

1 → 2 1 → 2 5 → 10 → 1 0 → 0 5 → 10 → 1

Step 2: Add all digits plus the NPI constant

Add the transformed values, the unchanged digits, and the constant 24.

2 + 8 + 2 + 1 + 1 + 0 + 0 + 0 + 9 + 1 + 0 + 24 = 48

Step 3: Find the amount needed to reach the next multiple of 10

The next multiple of ten after 48 is 50. The difference is the calculated check digit.

50 - 48 = 2

This NPI is valid

The calculated check digit is 2, which matches the last digit of 1811500952.
