Clinical Information

The procedure known as CPT code 45330 is a common medical procedure used to examine the colon and rectum for abnormalities, inflammation or growths such as polyps. The purpose of this procedure is to detect any tissue changes that may indicate the presence of a disease such as colon cancer. It is recommended that patients start getting screened through this procedure at the age of 50, or earlier if they have a higher risk of developing colon cancer.

Before the procedure begins, the patient is prepped appropriately and given anesthesia to ensure they are comfortable and relaxed during the exam. Once the patient is in a comfortable position, the provider inserts a sigmoidoscope through the anus and slowly advances it through the anal canal and rectum up to the sigmoid colon. During this process, the provider will carefully examine the walls of the colon for any signs of inflammation, growths or other abnormalities.

The provider will then inspect the sigmoid colon while carefully collecting any specimens that may be present. These specimens are typically collected through brushing or washing the internal surfaces of the colon. The provider will remove all the instruments and then gently withdraw the sigmoidoscope. The procedure usually lasts between 15 to 30 minutes.

While the procedure may cause slight discomfort or pressure, it is generally painless and well-tolerated by most patients. After the procedure, patients are monitored closely to ensure that there are no complications or signs of discomfort. It is common for patients to experience some mild cramping, bloating or gas after the procedure, which usually subsides in a few hours.

After the procedure, it is recommended that patients discuss the results of the exam with their healthcare provider to understand what was found and to receive follow-up recommendations. If abnormalities or growths were detected, additional testing may be recommended to further evaluate the area.

In conclusion, the CPT code 45330 procedure is a critical tool in detecting the presence of colon cancer or other abnormalities within the colon and rectum. It is a safe and effective procedure that is generally well-tolerated by most patients. It is important for patients to discuss their risk factors for colon cancer with their healthcare provider and to schedule regular screenings through this procedure starting at the recommended age to provide the best chance for early detection and treatment.
