There are 18 ICD-10-CM codes related to colon cancer. Of these, 16 are billable specific codes and 2 are non-billable header categories that organize the specific codes underneath them. Header codes cannot be reported on a claim by themselves.

Yes. 16 of the 18 ICD-10-CM codes for colon cancer are billable. Common examples include C18.0 (Malignant neoplasm of cecum); C18.1 (Malignant neoplasm of appendix); C18.2 (Malignant neoplasm of ascending colon). Code to the highest level of specificity supported by the documentation.

The most commonly used billable codes for colon cancer include: C18.0 (Malignant neoplasm of cecum); C18.1 (Malignant neoplasm of appendix); C18.2 (Malignant neoplasm of ascending colon). The correct code depends on the documented clinical presentation, including any complications, episode (acute / chronic), and laterality where applicable. Always code to the highest level of specificity supported by the clinical documentation.

No, C18 (Malignant neoplasm of colon) is a non-billable header code. You need to use a more specific child code for billing purposes.
