What Physical Therapy Assistant covers

(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.

Full NPPES record

An NPI-1 identifies a single person. It stays with the clinician for life, even if they move practice or change state, which is why the address on file can lag behind where they actually work today.

Number check

1861616609 passes the NPI check digit test The final digit 9 matches the value computed from the first nine digits, so this is a well-formed NPI.
How the check works, step by step

Every NPI carries a Luhn check digit — the same scheme used on credit cards. CMS prefixes the number with 80840 before computing it, which marks it as a US health identifier.

Digit 8 0 8 4 0 1 8 6 1 6 1 6 6 0
Doubled? ×2 ×2 ×2 ×2 ×2 ×2 ×2
Value 8 0 8 8 0 2 8 3 1 3 1 3 6 0

Sum = 51 · next multiple of 10 = 60 · check digit = 9 · actual last digit = 9

A valid check digit only means the number is well-formed. It does not mean the provider is licensed, active, or in good standing — those are separate questions answered by the sections above.
