What is a commonality between both the 1995 and 1997 documentation guidelines for physical exams?

The correct answer highlights that both the 1995 and 1997 documentation guidelines for physical exams require the documentation of abnormal findings. This requirement is significant because documenting abnormal findings is essential for establishing the medical necessity of the services provided. It ensures that the physician effectively communicates the patient's health status and the rationale for their treatment plan.

Abnormal findings contribute to the overall assessment and understanding of the patient's condition, which is crucial for coding and billing purposes. These findings are vital for creating a complete medical record and ensuring compliance with coding standards and guidelines. By mandating the documentation of these findings, both sets of guidelines emphasize the importance of accurate and thorough records in patient care.

While the other options also refer to components of the examination guidelines, they do not encapsulate a key requirement that is true for both sets of guidelines as clearly as the documentation of abnormal findings does.
