225200000X Physical Therapy Assistant

Definition

(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.

Where 225200000X sits

• Group: Respiratory, Developmental, Rehabilitative and Restorative Service Providers — code 42 of 82 in the group
• Classification: Physical Therapy Assistant 225200000X

Physical Therapy Assistant has no specializations, so 225200000X is the only code for it. A provider may report more than one taxonomy code on an NPI but marks one as primary.

Medicare

225200000X has no entry in the CMS Medicare Provider and Supplier Taxonomy Crosswalk. That usually means Medicare does not enroll this kind of provider under its own specialty — the provider can still hold an NPI and use this code on claims to other payers.

Related codes

No other codes share the classification Physical Therapy Assistant. The rest of Respiratory, Developmental, Rehabilitative and Restorative Service Providers is on the group page.

Similar codes in other groups

If 225200000X is not quite right, these codes in other groups share a word with it — often the same field practised by a different kind of provider:

Using 225200000X

The code goes in the taxonomy field of the NPI application in NPPES, and on claims where a payer asks for it — box 24J (shaded) or 33b on the CMS-1500 with the ZZ qualifier, or the PRV segment of an 837 electronic claim. Payers match it against the taxonomy on the NPI record and, for Medicare, against the specialty on the enrollment, so all three should agree. To see which code a provider uses, search their NPI in the lookup.
