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: Pathology Molecular Genetic Pathology
Taxonomy Code: 207ZP0007X
Type: Allopathic & Osteopathic Physicians
License No.: V9955
License State: TX
Taxonomy Description: A molecular genetic pathologist is expert in the principles, theory and technologies of molecular biology and molecular genetics. This expertise is used to make or confirm diagnoses of Mendelian genetic disorders, disorders of human development, infectious diseases and malignancies, and to assess the natural history of those disorders. A molecular genetic pathologist provides information about gene structure, function and alteration and applies laboratory techniques for diagnosis, treatment and prognosis for individuals with related disorders.

Secondary Taxonomies

The provider has reported to the NPI enumerator additional taxonomy codes. Multiple taxonomy codes may represent subspecialties or other areas of specialization the provider maybe licensed to practice.

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 1568858736, we treat the final digit (6) 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 74. The final step is to find the difference between that total and the next multiple of ten (80 - 74 = 6).

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 6 → 12 → 3 8 → 16 → 7 8 → 16 → 7 3 → 6

Step 2: Add all digits plus the NPI constant

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

2 + 5 + 1 + 2 + 8 + 1 + 6 + 5 + 1 + 6 + 7 + 6 + 24 = 74

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

The next multiple of ten after 74 is 80. The difference is the calculated check digit.

80 - 74 = 6

This NPI is valid

The calculated check digit is 6, which matches the last digit of 1568858736.
