Modifier 25

In the world of health insurance billing, the modifier 25 is used to indicate that a separate procedure or service was performed on the same day as another procedure or service. This modifier is typically used when a patient has a preventive exam and then receives additional treatment for an acute condition. The use of the modifier 25 ensures that the patient's insurer will reimburse the provider for both services. In addition, the modifier 25 can be used to indicate that a procedure was performed at a different body site than the one originally documented. For example, if a biopsy is performed on the right forearm but is subsequently found to be cancerous, the modifier 25 can be used to indicate that the subsequent surgery was performed on the left forearm. By using the modifier 25, healthcare providers can ensure that they are properly reimbursed for their services.
