ED Coding and Reimbursement Alert

Question: A 4-year-old boy presented to the ED with a lacerated foot. The physician administered conscious sedation, but the patient developed hypoxia, so the doctor never sutured the wound. Should I report the suturing with modifier -53 and administration of conscious sedation with no modifier?

Answer: Although technically you might be able to bill the suture code with modifier -53 (Discontinued procedure) along with the conscious sedation, most ED physician groups would not. Instead, you should bill the appropriate emergency department evaluation and management service (99281-99285) along with the conscious sedation code.
 
CPT instructs use of modifier -53 when the physician terminates a procedure because of circumstances that threaten the well-being of the patient (after induction of anesthesia and or surgical preparation). In this scenario, the physician has administered conscious sedation, but the developing hypoxia prevents completion of the repair.
