CPT modifier 53 for discontinued procedure indicates that a surgical or diagnostic procedure was started but discontinued.
Note: Ambulatory Surgical Centers (ASCs) may not submit CPT modifier 53.
Guidelines and Instructions
Submit CPT modifier 53 with surgical codes or medical diagnostic codes when the procedure is discontinued because of extenuating circumstances.
When appropriate, add CPT modifier 53 to the code reported by the physician or practitioner for the discontinued procedure. Additional actions are also required when this modifier is used.
Note: When an outpatient hospital or ASC is reporting a previously scheduled procedure/service that is partially reduced or canceled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia; see CPT modifiers 73 and 74.
