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: Occupational Therapist Physical Rehabilitation
Taxonomy Code: 225XP0019X
Type: Respiratory, Developmental, Rehabilitative and Restorative Service Providers
Taxonomy Description: Occupational therapists are experts at helping people lead as independent a life as possible. Occupational therapists bring an understanding of the physical and psychological implications of illness and injury and their effects on peoples' ability to perform the tasks of daily living. Occupational therapists provide interventions that can aide a person in completing ADL and IADL tasks, such as dressing, bathing, preparing meals, and driving. They also may fabricate custom orthotics to improve function, evaluate the environment for safety hazards and recommend adaptations to remove those hazards, help a person compensate for cognitive changes, and build a persons' physical endurance and strength. Occupational therapists' knowledge of adapting tasks and modifying the environment to compensate for functional limitations is used to increase the involvement of clients and to promote safety and success.

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 1255067468, 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.

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 5 → 10 → 1 0 → 0 7 → 14 → 5 6 → 12 → 3

Step 2: Add all digits plus the NPI constant

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

2 + 2 + 1 + 0 + 5 + 0 + 6 + 1 + 4 + 4 + 1 + 2 + 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 1255067468.
