Valid for Submission

C26.0 is a billable code used to specify a medical diagnosis of malignant neoplasm of intestinal tract, part unspecified. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code C26.0 might also be used to specify conditions or terms like malignant tumor of intestine or primary adenocarcinoma of intestinal tract or primary malignant neoplasm of intestinal tract.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: Neoplasm, neoplastic intestine, intestinal or Neoplasm, neoplastic intestine, intestinal tract NEC .

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code C26.0:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Malignant neoplasm of intestine NOS

Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Malignant tumor of intestine
  • Primary adenocarcinoma of intestinal tract
  • Primary malignant neoplasm of intestinal tract

Diagnostic Related Groups

The ICD-10 code C26.0 is grouped in the following groups for version MS-DRG V38.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). applicable from 10/01/2020 through 09/30/2021.

Table of Neoplasms

The code C26.0 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

Also called: Colon cancer, Rectal 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.

Intestinal Cancer

Also called: Duodenal cancer, Ileal cancer, Jejunal cancer, Small intestine cancer

Your small intestine is part of your digestive system. It is a long tube that connects your stomach to your large intestine. Intestinal cancer is rare, but eating a high-fat diet or having Crohn's disease, celiac disease, or a history of colonic polyps can increase your risk.

Possible signs of small intestine cancer include

  • Abdominal pain
  • Weight loss for no reason
  • Blood in the stool
  • A lump in the abdomen

Imaging tests that create pictures of the small intestine and the area around it can help diagnose intestinal cancer and show whether it has spread.

Surgery is the most common treatment. Additional options include chemotherapy, radiation therapy, or a combination.
