Can failed procedures after they are attempted (central line, a-line, or others) be coded?
Yes, you can code the failed procedure adding a 53 modifier, Discontinued Procedures, to indicate the procedure was shortened. If these procedures are attempted in an ambulatory care center (outpatient hospital/ASC), code the procedure with a 73 modifier if the failure occurred before anesthesia or with a 74 modifier if it occurred after anesthesia has been delivered.
