Taxonomy Description
An occupational therapist is a person who has graduated from an entry-level occupational therapy program accredited by the Accreditation Council for Occupational Therapy Education (ACOTE) or predecessor organizations, or approved by the World Federation of Occupational Therapists (WFOT), or an equivalent international occupational therapy education program; has successfully completed a period of supervised fieldwork experience required by the occupational therapy program; has passed a nationally recognized entry-level examination for occupational therapists, and fulfills state requirements for licensure, certification, or registration. An occupational therapist provides interventions based on evaluation and which emphasize the therapeutic use of everyday life activities (i.e., occupations) with individuals or groups for the purpose of facilitating participation in roles and situations and in home, school, workplace, community and other settings. Occupational therapy services are provided for the purpose of promoting health and wellness and are provided to those who have or are at risk for developing an illness, injury, disease, disorder, condition, impairment, disability, activity limitation, or participation restriction. Occupational therapists address the physical, cognitive, psychosocial, sensory, and other aspects of occupational performance in a variety of contexts to support engagement in everyday life activities that affect health, well-being, and quality of life.

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 1013835289, 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 51. The final step is to find the difference between that total and the next multiple of ten (60 - 51 = 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.

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 1 → 2 8 → 16 → 7 5 → 10 → 1 8 → 16 → 7

Step 2: Add all digits plus the NPI constant

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

2 + 0 + 2 + 3 + 1 + 6 + 3 + 1 + 0 + 2 + 1 + 6 + 24 = 51

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

The next multiple of ten after 51 is 60. The difference is the calculated check digit.

60 - 51 = 9
This NPI is valid
The calculated check digit is 9, which matches the last digit of 1013835289.
