- Taxonomy Description
- Occupational therapy practitioners are experts at identifying the cause of difficulties in performance of activities of daily living and instrumental activities of daily living. Occupational therapy practitioners evaluate the client, their environment, and their occupational performance in that environment, as well as make recommendations for products to improve the fit between the client, place, and activity. Occupational therapists can evaluate both the skills of the client and the environmental features that support or limit the performance of meaningful or necessary activities, thereby enhancing health, safety and well-being. Based on this assessment, they recommend modification and intervention strategies that improve the fit between the person and his or her environment.

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 1427931245, we treat the final digit (5) 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 65. The final step is to find the difference between that total and the next multiple of ten (70 - 65 = 5).
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.
Step 2: Add all digits plus the NPI constant
Add the transformed values, the unchanged digits, and the constant 24.
Step 3: Find the amount needed to reach the next multiple of 10
The next multiple of ten after 65 is 70. The difference is the calculated check digit.
