CPT® Code 46610

The CPT® Code 46610 refers to a specific medical procedure known as anoscopy, which involves the examination of the anal canal and lower rectum using a specialized instrument called an anoscope. This procedure is particularly focused on the removal of a single tumor, polyp, or other lesion utilizing either hot biopsy forceps or bipolar cautery. The process begins with the insertion of the obturator into the anoscope, which is then introduced into the anus. The physician advances the scope using a twisting motion while the patient bears down, facilitating easier access to the anal canal. Once the obturator is removed, the eyepiece is attached to the anoscope, allowing for a clear view of the internal structures. The scope is then carefully withdrawn to inspect the mucosa for any abnormalities, such as tumors or polyps. In the context of this procedure, hot biopsy forceps are employed to simultaneously excise and cauterize the tissue, utilizing an insulated monopolar forceps that applies electrical current to achieve this dual function. Alternatively, bipolar cautery is used, which also employs electrical current but operates differently by directing the current between two points on the forceps tip. Both methods are primarily indicated for the removal of small polyps and the treatment of vascular ectasias, which are abnormal blood vessel formations. This procedure is essential for diagnosing and treating various conditions affecting the anal and rectal areas, ensuring that any lesions are effectively managed to prevent further complications.
