We have patients that come to our hospital and have their Cystostomy catheters changed. The nurse removes the old catheter and cleanses the area w/ betadine and alcohol and inserts a #20 french 5 cc foley and applies triple antibiotic. We are wondering is CPT code 51705 could be billed for a nurse to perform this procedure. We have also referenced CPT Asst Dec 2007 page 13. Any help would be great!
