What ICD10 code would you use if the pathology states POSITIVE for KRAS mutation from a descending colon biopsy

The protein product of the normal KRAS gene performs an essential function in normal tissue signaling, and the mutation of a KRAS gene is an essential step in the development of many cancer. It is positive means, there is developed cancer, so you should code descending colon cancer. Use, C18.6 (Malignant neoplasm of descending colon) for the condition.
