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: Audiologist
Taxonomy Code: 231H00000X
Type: Speech, Language and Hearing Service Providers
License No.: 43
License State: AK
Taxonomy Description: (1) A specialist in evaluation, habilitation and rehabilitation of those whose communication disorders center in whole or in part in hearing function. Audiologists are autonomous professionals who identify, assess, and manage disorders of the auditory, balance and other neural systems. Audiologists provide audiological (aural) rehabilitation to children and adults across the entire age span. Audiologists select, fit and dispense amplification systems such as hearing aids and related devices. (2) An audiologist is a person qualified by a master's degree in audiology, licensed by the state, where applicable, and practicing within the scope of that license. Audiologists evaluate and treat patients with impaired hearing. They plan, direct and conduct rehabilitative programs with audiotry substitutional devises (hearing aids) and other therapy.

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 1740378959, 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 71. The final step is to find the difference between that total and the next multiple of ten (80 - 71 = 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.

Target digit

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 4 → 8 3 → 6 8 → 16 → 7 5 → 10 → 1

Step 2: Add all digits plus the NPI constant

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

2 + 7 + 8 + 0 + 6 + 7 + 1 + 6 + 9 + 1 + 0 + 24 = 71

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

The next multiple of ten after 71 is 80. The difference is the calculated check digit.

80 - 71 = 9

This NPI is valid

The calculated check digit is 9, which matches the last digit of 1740378959.
