Which of the following is an example of a Level I CPT modifier?

Level I CPT modifiers are used to provide additional details about medical services and procedures performed by healthcare professionals. They are numeric and typically indicate specific situations or circumstances related to a procedure.

The -25 modifier is a Level I CPT modifier, which is used to indicate that on the day a procedure was performed, the doctor also provided a significant, separately identifiable evaluation and management (E/M) service. This modifier is essential for billing purposes, as it helps clarify that the services provided are distinct and justify separate reimbursement.

In contrast, the other options represent modifiers that either do not fall under Level I or have different implications. For instance, while -50 indicates bilateral procedures, -24 is a modifier used for unrelated E/M services during a postoperative period, and -76 denotes a repeat procedure by the same physician or provider. Therefore, each of these options serves a distinct purpose within the CPT coding system, making -25 the appropriate choice as an example of a Level I CPT modifier.
