Urologist does an open debridement of necrotic tissue found on the exterior of the bladder and the peritoneal reflection. Bladder was irrigated and small clots cleared. No leaks or masses are noted, so he elects not to open the bladder. No cystoscopy is performed. Debridement is performed on the infected, necrotic area of the right lateral bladder wall and the peritoneal reflection. Original source and etiology are unclear. All necrotic tissue was debrided, the area washed out, two drains placed.

Do I go with debridement codes? The only thing I’ve come close to that doesn’t involve cystoscopy/the interior of the bladder is 11043.

Any help or thoughts would be appreciated.
