Question: What are the limitations of colonoscopy (44388-44397; 45355- 45392)?

Answer: Be wary if your gastroenterologist performed colonoscopy for the following conditions. Colonoscopy is generally not covered for treating them. You should have additional documentation that indicates the medical necessity of the procedure when you submit your records for review by the payer. These conditions are:

• Chronic, stable, irritable bowel syndrome or chronic abdominal pain. There are unusual exceptions in which the colonoscopy may be done once to rule out organic disease, especially if symptoms are unresponsive to therapy.
• Acute limited diarrhea.
• Hemorrhoids.
• Metastatic adenocarcinoma of unknown primary site in the absence of colonic symptoms when it will not influence management.
• Routine follow-up of inflammatory bowel disease (except for cancer surveillance in chronic ulcerative colitis).
• Routine examination of the colon in patients about to
• undergo elective abdominal surgery for non-colonic disease.
• Upper GI bleeding or melena with a demonstrated upper GI source.

How it’s done: Colonoscopy is a visual examination of the lining of the large intestine with a rigid or flexible video or fiberoptic endoscope. The colonoscope is inserted anally or through a stoma and is advanced through the large intestine to the ileocecal valve under direct vision using the scope’s optical system.
