⚠️ Audit Risk — Action Required
Modifier 25 claims may be subject to medical record review and post-payment audit. Ensure your documentation clearly supports:
A significant, separately identifiable E/M service was performed
The E/M was beyond the usual pre-/post-operative care for the procedure
Medical necessity is clearly documented in the patient record
📄 Reminder: Preventive Services Policy (Effective June 1, 2024)
E/M services billed on the same date as a preventive service are also reimbursed at 50% of the allowed amount under an existing separate policy.
Recommended Action Steps
Review your current billing workflows for same-day E/M + minor procedure encounters
Educate providers and coding staff on updated reimbursement rates effective May 1, 2026
Audit recent claims where Modifier 25 was used to identify documentation gaps
Confirm Modifier 57 is being used (not 25) when the E/M leads to a major surgical procedure
