C78.4 is a billable diagnosis code used to specify a medical diagnosis of secondary malignant neoplasm of small intestine. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Clinical Information
Duodenal Neoplasms
tumors or cancer of the duodenum.Duodenum
the shortest and widest portion of the small intestine adjacent to the pylorus of the stomach. it is named for having the length equal to about the width of 12 fingers.Jejunal Neoplasms
tumors or cancer in the jejunum region of the small intestine (intestine, small).Jejunum
the middle portion of the small intestine, between duodenum and ileum. it represents about 2/5 of the remaining portion of the small intestine below duodenum.

Table of Neoplasms
This code is referenced 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.

Patient Education
Intestinal 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.
