intraperitoneal saline fluid from previous procedure that day


Best answers
I have a patient who underwent a cysto/turbt earlier in the day. Later in the day doctor went back and did exploratory laparotomy, cystorrhaphy, and evacuation of 2.3 liters if saline with evaluation of bowel and intra-abdominal structures. He dictates they dissected down and entered into the peritoneum. At his point, there was moderate amount of fluid that was evacuated out and initially around 300-400 mL of saline was evacuated out of the abdominal cavity. We continued to free up this area and eventually enter the space of Retzius, freeing up the urinary bladder.

Would 49084 be appropriate for this procedure with diagnosis of R18.8?
