- Taxonomy Description
- (1)Physical therapist assistants are skilled health care providers who are graduates of a physical therapist assistant associate degree program accredited by an agency recognized by the Secretary of the U.S. Department of Education or Council on Postsecondary Accreditation, who assists the physical therapist in providing physical therapy. The supervising physical therapist is directly responsible for the actions of the physical therapist assistant. The PTA performs physical therapy procedures and related tasks that have been selected and delegated by the supervising physical therapist. Duties of the PTA include assisting the physical therapist in implementing treatment programs, training patients in exercised and activities of daily living, conducting treatments, and reporting to the physical therapist on the patient's responses. In addition to direct patient care, the PTA may also perform such functions as patient transport, and clinic or equipment preparation and maintenance. Currently more than half of all states require PTAs to be licensed, registered or certified. (2) An individual who works under the supervision of a physical therapist to assist him or her in providing physical therapy services. A physical therapy assistant may, for instance, help patients follow an appropriate exercise program that will increase their strength, endurance, coordination, and range of motion and train patients to perform activities of daily 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 1790631802, we treat the final digit (2) 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 58. The final step is to find the difference between that total and the next multiple of ten (60 - 58 = 2).
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 58 is 60. The difference is the calculated check digit.
