Colon cancer is known as one of the most common cancer type in US, affecting both men and women with the highest rate happens to those with African American heritage race. Anyone can actually have this disease with some factors put them at higher risk.

Although it commonly rises when a person is over 50 age, it is reported many cases happening to younger individuals every year. They do not be included as high risk patients. Even unhealthy diet and lifestyle can promote the disease occurrence, making the ICD 10 Colon Cancer coding get more complicated.

ICD 10 Colon Cancer

Colon cancer can be found on the lower part of the digestive system. It is called rectal cancer if the location is in the last several inches of the colon. However, sometimes, doctors just refer them to colorectal cancer. at first, the condition is started with small, benign adenomatous polyps. Then they turn to be cancerous. They usually show no symptoms at all.

Therefore, immediate screening is required to detect the development of cancer cells, especially those carrying the high risk factors. Besides being used as preventive action, colon cancer screening is aimed to help people save their money on treatment costs through the screening colonoscopy for colon cancer code claiming.

If a patient has been positively diagnosed for having cancer colon, whether it is trough screening or diagnostic test, the health providers can use different codes to claim the reimbursement.

They can use ICD10 Colon Cancer, i.e. C18. Depending on its actual site, the codes may vary as follows:

C18.0 – malignant neoplasm of cecum

C18.1 – malignant neoplasm of appendix

C18.2 – malignant neoplasm of ascending colon

C18.3 – malignant neoplasm of hepatic flexure

C18.4 – malignant neoplasm of transverse colon

C18.5 – malignant neoplasm of splenic flexure

C18.6 – malignant neoplasm of descending colon

C18.7 – malignant neoplasm of sigmoid colon
