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: Radiology Practitioner Assistant
Taxonomy Code: 243U00000X
Type: Technologists, Technicians & Other Technical Service Providers
Taxonomy Description: A Radiology Practitioner Assistant (RPA) is a health professional certified as a registered radiographer with the American Registry of Radiologic Technologists (ARRT) and, in addition, is credentialed to provide primary radiology health care with radiologist supervision. Radiology Practitioner Assistants are qualified by graduation from an educational program recognized by the Board of Directors of athe Certification Board for Radiology Practitioner Assistants (CBRPA) and certified by the CBRPA. Within the Radiologist/RPA relationship, Radiology Practitioner Assistants exercise autonomy in decision making in the role of a primary caregiver with regard to patient assessment, patient management and in providing a broad range of radiology diagnostic and interventional services. The clinical role of the Radiology Practitioner Assistant includes primary and specialty care in radiology practice settings in rural and urban areas.

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 1437005808, we treat the final digit (8) 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 52. The final step is to find the difference between that total and the next multiple of ten (60 - 52 = 8).

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 3 → 6 0 → 0 5 → 10 → 1 0 → 0

Step 2: Add all digits plus the NPI constant

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

2 + 4 + 6 + 7 + 0 + 0 + 1 + 0 + 8 + 0 + 24 = 52

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

The next multiple of ten after 52 is 60. The difference is the calculated check digit.

60 - 52 = 8

This NPI is valid

The calculated check digit is 8, which matches the last digit of 1437005808.
