Podiatry Coding & Billing Alert

Question: Our surgeon had to cancel a surgery midway through a procedure for the patient’s health. Are there any guidelines for whether I should use modifier 52 or 53 in this case?

Answer: Modifier 53 (Discontinued procedure) is the correct modifier to report for terminated surgeries “due to extenuating circumstances or those that threaten the wellbeing of the patient,” according to the CPT^® code book. Your example warrants the use of modifier 53.

According to Appendix A in the CPT^® code book, modifier 53 “is not used to report the elective cancellation of a procedure prior to the patient’s anesthesia induction and/or surgical preparation in the operating suite.” This means, when reporting physician services, you may not bill for the surgical service in any capacity if the procedure is terminated prior to anesthesia.

You may use modifier 52 (Reduced services) in a variety of contexts. For instance, you can append it to surgical codes that are inherently bilateral but that your surgeon performs unilaterally. Modifier 52 is not the appropriate choice for your example.
