Cardiology Coding Alert

Question: My cardiologist performed external electrocardiographic recording for 40 hours by continuous rhythm recording and storage. They performed the recording, scanning analysis with report, review, and interpretation. This all occurred in their office on equipment they owned. How should I report this service?

Answer: You have described a global Holter monitoring service for which you should report 93224 (External electrocardiographic recording up to 48 hours by continuous rhythm recording and storage; includes recording, scanning analysis with report, review and interpretation by a physician or other qualified health care professional).

Don’t miss: To appropriately bill 93224, your cardiologist must own the equipment. Your cardiologist should also instruct the patient on how to use the Holter monitor during a 93224 encounter. Additionally, since 93224 represents both the technical and professional components of the service, you should not append modifiers 26 (Professional component) or TC (Technical component) to this code.
