Hello, this is Sungmo Best Internal Medicine, where we perform colonoscopies in Siheung-si. As the new year begins, the number of people planning health check-ups significantly increases. If you are considering adding a colonoscopy to your check-up list this year, this article, which summarizes the cost and conditions for claiming actual expense insurance, may be helpful.

While many more people are consistently getting national health check-ups, a considerable number still feel burdened by colonoscopies. This is because the bowel preparation process can be cumbersome, and some feel a reluctance about the insertion of an endoscope through the anus.

Nevertheless, a colonoscopy is a crucial examination for the early detection of various colorectal diseases, including colorectal cancer, making it difficult to overlook. According to data from the National Cancer Information Center, colorectal cancer patients accounted for 12.7% of all cancer patients in 2021, and the mortality rate was also high. It is important not to miss the appropriate timing for an examination by postponing it due to inconvenience.

If you experience recurring diarrhea and constipation or persistent irregular bowel movements, it could potentially be a colorectal disease in a broader sense. While it might be due to your condition or the food you ate, if symptoms persist, getting an examination to confirm is a safe choice.

At Sungmo Best Internal Medicine, a colonoscopy is performed by inserting a long tube, about 1 cm in diameter, with a small camera attached, through the anus. We can examine the entire large intestine, from the rectum to the sigmoid colon, descending colon, transverse colon, and ascending colon.

• If polyps are found during the examination, removal treatment can be performed immediately.
• We offer comfortable sleep colonoscopies performed under sedation.
• The procedure is conducted in a calm, sedated state, which tends to reduce discomfort during the examination.

If you are curious about the preparation process before the examination, we recommend checking the procedures in advance through the Examination Guide.

The most accurate amount can be confirmed by inquiring with the hospital where you will be examined in advance, and it may vary depending on the individual.

To get straight to the point, both colonoscopy costs and polyp removal costs may be eligible for actual expense insurance claims. However, there are prerequisites.

• The examination must be performed due to a doctor's suspicion of a disease after a medical consultation.
• Policy terms vary depending on the insurance company and product you are subscribed to, so prior confirmation is essential.

Required Documents for Claiming

• Copy of identification card
• Diagnosis certificate
• Medical expense receipt and detailed statement

• If there are no particular abnormalities: Approximately once every 5 years
• If polyps have been found or there is a family history: Approximately once every 1-2 years

Cancer often has almost no early symptoms, making it difficult to detect on your own. That's why it's important to periodically check your body's condition when you are not sick and when you are healthy. If you would like to schedule an examination, please check the Clinic Hours Information and plan your visit.
