Summary
This policy clarifies the use of Modifier 25 for billing a significant, separately identifiable Evaluation and Management (E/M) service on the same day as a procedure or other service by the same physician or qualified healthcare professional. The policy became effective January 1, 2026, and billing teams must ensure proper documentation and coding practices to support Modifier 25 usage and avoid claim denials.
Action Required
By January 1, 2026: Billing team must review and implement updated guidance on Modifier 25 usage for same-day E/M services. Providers must document the significant, separately identifiable E/M service distinct from the procedure performed. Update encounter templates and billing system validation rules to require proper documentation supporting Modifier 25 claims. Educate clinical and billing staff on when Modifier 25 is appropriate (E/M service must be separately identifiable and medically necessary, not just an extension of the procedure). Train coders to audit claims for compliant Modifier 25 usage. Claims submitted with Modifier 25 lacking proper documentation support will be denied or downcoded by payers.
