What 97164 covers
A physical therapist uses this service to reassess a patient who already has an established physical therapy plan of care. The re-evaluation may include reviewing the patient’s history, examining current impairments and function, and using appropriate tests or measures to determine whether the plan needs revision. It is distinct from routine monitoring during treatment and from an initial physical therapy evaluation. It is commonly performed in an outpatient therapy clinic, including for patients whose mobility or function has changed during rehabilitation or who are not progressing as expected.
Report 97164 when the reassessment supports a revised plan of care, with documentation of the current findings, the reason for re-evaluation, and any resulting changes to goals or treatment. It is not a timed treatment unit. CMS treats this as a therapy service without a separate professional component, so it is reported without modifier 26. When multiple therapy units are reported for the same day, CMS reduces the practice expense for the second and later units.
