Which statement best describes the diagnosis in PT practice?

• A. The plan of care guides future interventions
• B. Insurance justification is the main purpose of diagnosis
• C. A label given to patients based on clusters of signs and symptoms found during evaluation
• D. The evaluation determines prognosis

Answer: (C)

In physical therapy practice, diagnosis is a label assigned after evaluating the patient, based on patterns of signs, symptoms, and functional observations. This labeling captures the condition or category that best explains the impairments and guides how the patient should be managed over time. The plan of care uses that diagnosed condition to tailor specific interventions, and prognosis is informed by the diagnosis and overall assessment. The idea that the diagnosis is mainly for insurance justification isn’t correct, and saying the evaluation alone determines prognosis misses how diagnosis, prognosis, and plan of care work together.
