E/M Elements: Keep Accurate ROS Count to Make Correct E/M Decision

Why This Topic Matters

Accurate ROS counting is a key part of supporting the correct E/M level and avoiding undercoding or overcoding risk. The topic matters for practices that rely on compliant history documentation to substantiate visit intensity and payment.
