A surgical procedure involving a partial cystectomy for a tumour or diverticulum (either single or multiple). This service specifically includes the reimplantation of one ureter into the bladder. This service is eligible for surgeon (<suffix>A</suffix>), assistant (<suffix>B</suffix>), and anaesthetist (<suffix>C</suffix>) fees. The fee for the assistant is calculated with 6 base units, and the anaesthetist fee with 7 base units, plus applicable time units for both as per and . When this procedure is performed laparoscopically, premium code E792 may be claimed for a 25% increase to the surgical fee.

When to Use

Use S483 when performing a partial cystectomy specifically involving the excision of a bladder tumour or diverticulum combined with the mandatory reimplantation of one ureter.
Use S483 for cases requiring bladder wall resection where ureteral involvement necessitates surgical relocation, distinguishing it from simple bladder diverticulectomy (S482) which does not include ureteral reimplantation.

Common Pitfalls

Claiming S483 when the ureter is not reimplanted; if only the bladder wall is excised without ureteral involvement, the procedure may not meet the criteria for this specific code.
Failing to append E792 when the procedure is performed laparoscopically, resulting in a 25% underpayment of the surgical fee.
Incorrectly billing S483 alongside other bladder procedures that are considered inclusive of the surgical work, leading to potential audit flags for unbundling.

Billing Tips

Always verify if the procedure qualifies for the E792 laparoscopic premium, as this is a significant fee modifier that must be submitted on the same claim.
Ensure the surgical assistant and anaesthetist are aware that S483 is on the pre-approved list for a second assistant if clinical complexity requires additional support.
