I have a patient whose procedure was discontinued today after the administration of anesthesia, so we are billing with the discontinued procedure modifier. However, the patient is coming back in a few days again for the procedure. Do we need to bill a repeat procedure modifier or will the insurance accept both claims?

Also, the procedure was 29881 and I saw in Supercoder that 53 is an acceptable modifier to bill discontinued procedure for the surgeon, but the modifier I was considering for the ASC side, 74, was not listed. Does anyone know why?

Thank you!!
