Colonoscopy CPT Code

Colonoscopy is a diagnostic procedure to check the abnormality in rectum and large intestine. In this process, a large, thin tube optical fiber is inserted inside the body through anus. This optic fiber is used for the diagnosis of abnormality in large intestine. A tiny video camera is inserted on the tip of this optic fiber and this camera shows the inner side of large intestine and rectum. During colonoscopy, any kind of abnormal tissue or polyps can be removed from the colon. The process is named after the part of body it targets i.e. colon. Biopsy sample can also be obtained via this process. In biopsy, a tissue sample is removed for further diagnosis.


    Colonoscopy is performed for the diagnostic purpose and to remove the defective cells from the colon but there are some complications which may appear. Common complications include;


    • Bleeding from the site of tissue sampling (biopsy).
    • Colon and rectum muscle tear may occur. 
    • The sedative agent used during the process may cause an adverse reaction.


    A doctor always proposes a consent form to sign before the procedure. This consent form includes all the information regarding possible complications. There are some special instructions which should be followed before the procedure starts.
