AAPC Certified Professional Coder (CPC) — Question 92

This 27-year-old male has morbid obesity with a BMI of 45 due to a high calorie diet. He has decided to have an open Roux-en-Y gastric bypass. The patient is brought to the operating room and placed in supine position. A midline abdominal incision is made. The stomach is mobilized, and the proximal stomach is divided and stapled creating a small proximal pouch in continuity with the esophagus. A short limb of the proximal bowel of 155 cm is divided. It is brought up and anastomosed to the gastric pouch. The other end of the divided bowel is connected back into the distal small bowel to the short limb's gastric anastomosis to restore intestinal continuity. The abdominal incision is closed.
