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: Specialist/Technologist, Other Surgical Assistant
Taxonomy Code: 246ZC0007X
Type: Technologists, Technicians & Other Technical Service Providers
License No.: SA.0003179
License State: CO
Taxonomy Description: A surgical assistant is a skilled practitioner who has undergone formalized education and training as a surgical assistant. The surgical assistant performs surgical functions that include, but are not limited to: retracting, manipulating, suturing, clamping, cauterizing, litigating, and tying tissue; suctioning, irrigating and sponging; positioning the patient; closure of body planes and skin; and participating in hemostasis and volume replacement. Surgical assistants are certified and registered or licensed by the state, or, in states without licensure, certified as surgical assistants by completing appropriate education and training.

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 1093181679, we treat the final digit (9) 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 61. The final step is to find the difference between that total and the next multiple of ten (70 - 61 = 9).

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 9 → 18 → 9 1 → 2 1 → 2 7 → 14 → 5

Step 2: Add all digits plus the NPI constant

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

2 + 0 + 1 + 8 + 3 + 2 + 8 + 2 + 6 + 1 + 4 + 24 = 61

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

The next multiple of ten after 61 is 70. The difference is the calculated check digit.

70 - 61 = 9

This NPI is valid

The calculated check digit is 9, which matches the last digit of 1093181679.
