Summary
This policy clarifies the requirements for applying Modifier 25 to Evaluation and Management (E/M) services billed on the same day as a procedure or other service by the same provider. The policy defines what constitutes a 'significant, separately identifiable' E/M service under Medicare Advantage plans effective April 1, 2025. Billing teams must ensure proper documentation and modifier application to avoid claim denials.
Action Required
By April 1, 2025: Billing team must review and update coding guidelines to ensure compliance with Modifier 25 requirements for same-day E/M and procedure billing. Providers must document the separate, identifiable nature of E/M services performed on the same day as procedures. Update encounter templates and billing system rules to enforce Modifier 25 documentation standards. Train all clinical and billing staff on proper application of Modifier 25 to avoid incorrect modifier usage. Failure to properly apply Modifier 25 or document separately identifiable services will result in claim denials or downcoding by Medicare Advantage plans.
