Outpatient physical therapy services cannot be initiated until:

The initiation of outpatient physical therapy services requires that an initial plan of care has been established. This plan is a crucial component because it outlines the specific therapies, goals, and treatment approaches tailored to the patient's condition and needs. It serves as a roadmap for both the healthcare provider and the patient, ensuring that the therapy is purposeful and appropriate.

An initial plan of care is necessary for a few reasons: it helps in setting measurable goals, provides guidelines for the duration and frequency of therapy, and aids in monitoring the patient's progress over time. Healthcare professionals must have a well-defined plan to justify the ongoing need for therapy and to document the medical necessity for the services provided during the claims process.

In contrast, other options presented do not align with the requirements set forth for initiating therapy services. For instance, a patient being fully rehabilitated might imply that therapy is no longer needed, insurance claim approval is administrative and does not dictate the necessity of treatment, and a follow-up visit does not establish or validate the initial need for therapy services. Thus, the establishment of a plan of care is a critical first step in the provision of outpatient physical therapy services.
