Reader Question:

Belly Button Differentiates 'Upper' from 'Lower' Abdomen

Question: What is the best way to determine the correct anesthesia codes for upper and lower abdominal intraperitoneal procedures?

West Virginia Subscriber

Answer: The patient’s belly button is the dividing line between upper and lower code choices. If the surgery is on an organ that is internally below the belly button, it’s a lower abdominal procedure and is coded with 00840 (Anesthesia for intraperitoneal procedures in lower abdomen including laparoscopy; not otherwise specified). If the surgery site is above the belly button, consider it an upper abdominal procedure and report 00790 (Anesthesia for intraperitoneal procedures in upper abdomen including laparoscopy; not otherwise specified).

You should also be familiar with what constitutes intraperitoneal and extraperitoneal classifications:

  • Intraperitoneal – within the peritoneal cavity and including the stomach, liver, gallbladder, spleen, jejunum, ascending and transverse colon, appendix, cecum, ileum, and sigmoid colon
  • Extraperitoneal: outside or behind the peritoneum and including the ureter, urinary bladder, kidneys, adrenal glands, lower esophagus, aorta, and inferior vena cava.
