Modifier 25: Significant Separately Identifiable E/M Service
Modifier 25 is used when a significant, separately identifiable E/M is provided the same day as a procedure.
When to Append Modifier 25
Append to an E/M code when a physician performs a significant and separately identifiable E/M service on the same day as another procedure. The E/M must be above and beyond the pre/post-service work included in the procedure.
- Clinical notes must separately document the E/M service and the procedure as distinct encounters with distinct medical decision making.
- Using modifier 25 on every E/M + procedure claim without confirming the E/M was clinically distinct.
- Overuse triggers audits.
