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.

Taxonomy Description
Legal Medicine is a special field of medicine that focuses on various aspects of medicine and law. Historically, the practice of legal medicine made contributions to medicine as a scientific instrument to solve criminal perplexities. Since World War II, the domain of legal medicine has broadened to include not only aspects of medical science to solve legal and criminal problems but aspects of law as it applies to medicine. Legal Medicine continues to grow as medicolegal issues like medical malpractice and liability, government regulation of health care, issues of tort reform, and moral and ethical complexities presented by technological advances become increasingly prominent. Many medical schools have implemented courses which supply medicolegal instruction for medical students, and many law schools now offer medicolegal courses. Also, dual degree programs in law and medicine have been created to assist physicians to bridge the gap between medicine and the law.

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 1598815748, 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 72. The final step is to find the difference between that total and the next multiple of ten (80 - 72 = 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.

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 8 → 16 → 7 5 → 10 → 1 4 → 8

Step 2: Add all digits plus the NPI constant

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

2 + 5 + 1 + 8 + 8 + 1 + 6 + 1 + 1 + 0 + 7 + 8 + 24 = 72

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

The next multiple of ten after 72 is 80. The difference is the calculated check digit.

80 - 72 = 8
This NPI is valid
The calculated check digit is 8, which matches the last digit of 1598815748.
