Coding Modifier 24

As per the CPT descriptive, modifier 24 is defined as an “Unrelated Evaluation and Management Service by the Same Physician or Other Qualified Healthcare Professional During a Postoperative Period.”  We would utilize this modifier to describe an unrelated E/M service during the global period of another procedure. Modifier 24 designates the provider is evaluating the patient for a new problem, and the evaluation is not included in a previous procedure’s global surgical package.

It is important to note when reporting modifier 24, the evaluation and management service must meet three criteria. The E/M service occurs during the postoperative period of another procedure, the current E/M service is unrelated to the previous procedure (you should be able to connect the E/M service to a separate, distinct diagnosis), and the same provider (or one with the same tax ID) who performed the previous procedure provides the E/M.
