Modifier 53 could almost be stated to as a forgotten modifier; practices forget or just never find out how to appropriately use it. This is often partially because there’s no set definition for ‘extenuating circumstances,’ leaving it susceptible interpretation and diminishing appropriate use. It’s especially unfortunate how disused modifier 53 is, because by not using it, practices miss out on partial payment for the work that was done by getting reimbursed for the expense of procedural prep. Using modifier 53 when the procedure is discontinued also ensures the instance for the provider to completely bill that very same procedure later, when it can be performed in its entirely.
As noted earlier, the qualifying discontinued service codes for modifier 53 are very specific. CPT® Appendix A states, “Under certain circumstances, the physician may elect to terminate a surgical or diagnostic procedure. Due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. This circumstance may be reported by adding the modifier ‘53’ to the code reported by the physician for the discontinued procedure.”
