ICD-10 Diagnosis Code D01.49

• 374 - DIGESTIVE MALIGNANCY WITH MCC
• 375 - DIGESTIVE MALIGNANCY WITH CC
• 376 - DIGESTIVE MALIGNANCY WITHOUT CC/MCC

General Equivalence Map
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

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.

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.
