CPT® Code 46930

The procedure described by CPT® Code 46930 involves the destruction of internal hemorrhoids through the application of thermal energy. Internal hemorrhoids are abnormal, sac-like protrusions formed by swollen blood vessels located within the rectum. These hemorrhoids can sometimes protrude through the anus, a condition known as prolapse, and may become thrombosed, leading to significant discomfort and complications. The procedure begins with the gentle dilation of the anal canal, which is typically achieved by the insertion of one or two gloved fingers. This allows for better access to the hemorrhoid. Once the hemorrhoid is identified, it is grasped using forceps, and traction is applied to draw it out of the anal canal for treatment. The thermal energy is then applied to the tissue located just proximal to the hemorrhoid. There are three primary methods of delivering this thermal energy: infrared coagulation, which utilizes infrared light; cautery, which employs an electrocautery probe; and radiofrequency, which uses an electrode. Each of these methods generates a thermal lesion, or burn, in the targeted tissue, effectively disrupting the blood supply to the hemorrhoid. This disruption leads to the shrinkage of the hemorrhoid, alleviating the symptoms associated with this condition.
