If 99024 is being documented for follow-up exams in the global period but is not being billed out, or tracked, does it need an ICD-10 code as long as there is sufficient documentation in the chart for the followup exam and documentation of the original date of the procedure? If there is sufficient documentation in the chart for the followup visit will it pass an audit without an ICD-10 code?

Thank you;
