How to Bill Modifier 25 Correctly (and When You Cannot)
Modifier 25 identifies a significant, separately identifiable E/M service. A second diagnosis or a longer note alone does not justify it.
Identify the separate work
Assess whether the E/M goes beyond work normally included in the other service. Document the distinct evaluation and management performed.
Support medical necessity
Choose the E/M level from its applicable criteria. Do not add a problem visit just because a procedure or preventive service occurred.
Check the G2211 exception
Medicare permits specified same-day preventive-service exceptions for eligible office E/M-25. Other procedures do not automatically qualify.
