Code Classification

  • Neoplasms (C00–D48)
    • Malignant neoplasms of digestive organs (C15-C26)
      • Malignant neoplasm of colon (C18)

C18.0 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of cecum. The code C18.0 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.

The ICD-10-CM code C18.0 might also be used to specify conditions or terms like adenocarcinoma of cecum, carcinoma of cecum, malignant tumor of cecum, primary malignant neoplasm of cecum, primary malignant neoplasm of ileocecal valve , primary malignant neoplasm of ileum, etc.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: caput coli ; cecum ; ileocecum, ileocecal (coil) (junction) (valve) ; intestine, intestinal large caput coli ; intestine, intestinal large cecum ; intestine, intestinal large colon caput ; intestine, intestinal large ileocecum, ileocecal (coil) (valve) ; etc

Tabular List of Diseases and Injuries

Table of Neoplasms

The code C18.0 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

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.
