ICD-10-CM Code C78.5

Secondary malignant neoplasm of large intestine and rectum

Version 2020 Billable Code Neoplasm Malignant Secondary

Valid for Submission

C78.5 is a billable code used to specify a medical diagnosis of secondary malignant neoplasm of large intestine and rectum. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code C78.5 might also be used to specify conditions or terms like malignant neoplasm of rectum, rectosigmoid junction and anus, malignant tumor involving rectum by direct extension from endometrium, malignant tumor involving rectum by direct extension from fallopian tube, malignant tumor involving rectum by direct extension from ovary, malignant tumor involving rectum by direct extension from prostate, malignant tumor involving rectum by direct extension from uterine cervix, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: anorectum, anorectal (junction) ; anus, anal ; anus, anal canal ; anus, anal cloacogenic zone ; anus, anal sphincter ; appendix ; canal ; etc

Table of Neoplasms

The code C78.5 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Information for Patients


Colorectal Cancer

The colon and rectum are part of the large intestine. Colorectal cancer occurs when tumors form in the lining of the large intestine. It is common in both men and women. The risk of developing colorectal cancer rises after age 50. You're also more likely to get it if you have colorectal polyps, a family history of colorectal cancer, ulcerative colitis or Crohn's disease, eat a diet high in fat, or smoke.

Symptoms of colorectal cancer include

  • Diarrhea or constipation
  • A feeling that your bowel does not empty completely
  • Blood (either bright red or very dark) in your stool
  • Stools that are narrower than usual
  • Frequent gas pains or cramps, or feeling full or bloated
  • Weight loss with no known reason
  • Fatigue
  • Nausea or vomiting

Because you may not have symptoms at first, it's important to have screening tests. Everyone over 50 should get screened. Tests include colonoscopy and tests for blood in the stool. Treatments for colorectal cancer include surgery, chemotherapy, radiation, or a combination. Surgery can usually cure it when it is found early.
