V-Y Anoplasty and Excision of Mucosal Ectropion
A 50-year-old patient, status post intersphincteric proctectomy with colo-perineal anastomosis and pelvic radiation due to rectal cancer, is admitted for surgical treatment of an anal mucosal ectropion and fecal incontinence. During surgery, the mucosal ectropion was excised and V-Y anoplasty was done. An endorectal ultrasound revealed an absence of the internal sphincter. Examination revealed anal gaping and exposed rectal mucosa within the anal canal. The largest amount of exposed rectal mucosa was found on the patient's left side which was the site chosen for the anoplasty. A mucosectomy was performed with preservation of the muscularis propria. A skin advancement flap was performed using perianal skin, which was advanced into the anal canal. What is the appropriate root operation for the V-Y anoplasty procedure? When referencing "anoplasty" in the ICD-10-PCS index, root operations "Repair" and "Supplement" are listed as the root operation options. However, this procedure appears to meet the root operation definition for Transfer. Additionally, is it appropriate to separately report the excision of mucosal ectropion? What are the appropriate code assignments for this procedure? ...

Article Overview
This premium article reviews a surgical coding question centered on a colorectal reconstructive procedure after rectal cancer treatment. It focuses on how the case is analyzed for ICD-10-PCS root operation assignment and the broader documentation details that support the coding discussion. The article is useful for inpatient coders, coding educators, and auditors working with colorectal surgery and post-procedural reconstruction cases.
Why This Topic Matters
Accurate root operation assignment is essential for correct ICD-10-PCS reporting in complex reconstructive procedures. This topic is especially relevant when documentation includes both excision and flap-based repair elements and the coding choice is not immediately straightforward.
