Straighten Out Modifiers 52 and 53

Question: The ob-gyn cancelled a surgical procedure prior to anesthesia induction due to the patient's abnormal EKG and recent left-arm pain. Should I use modifier 52 or 53 in this circumstance?

Answer: You should simply report the patient's inpatient care (99221-99223) for that day. Modifier 53 (Discontinued procedure) requires a surgical prep and anesthesia induction. You can report modifier 52 (Reduced services) only when the ob-gyn did something toward the surgery but was not successful or elected not to perform part of the procedure that was described in the code that you billed.
