In simple words: A virtual colonoscopy uses a CT scanner to take detailed pictures of your colon.It's used to look for things like polyps or cancer.You will need to clean out your colon beforehand, and a small tube will be inserted into your rectum to inflate the colon with air for better viewing.

This code represents a diagnostic computed tomography (CT) colonography procedure performed without contrast material, encompassing image post-processing.It's utilized to examine the colon for polyps, cancer, and other abnormalities. The procedure involves a bowel preparation similar to a conventional colonoscopy. During the procedure, a small tube is inserted into the rectum, and the colon is inflated with air or carbon dioxide. The CT scanner then takes cross-sectional images that are reconstructed into two- and three-dimensional images of the colon.

Example 1: A patient presents with abdominal pain and a change in bowel habits. A traditional colonoscopy is attempted but cannot be completed due to a stricture. A CT colonography without contrast (74261) is ordered to complete the examination of the colon., A patient with a history of colon cancer requires surveillance.Due to their age and other health concerns, a traditional colonoscopy is deemed too risky. A CT colonography without contrast (74261) is performed as a less invasive alternative., A patient is experiencing rectal bleeding. They opt for a CT colonography without contrast (74261) as a primary diagnostic tool before considering a traditional colonoscopy.

Documentation should include the reason for the procedure, relevant medical history, bowel preparation details, findings, and interpretation report.
