Short Description:Malignant neoplasm of overlapping sites of small intestine
Long Description:Malignant neoplasm of overlapping sites of small intestine

Code Classification

  • Neoplasms (C00–D48)
    • Malignant neoplasms of digestive organs (C15-C26)
      • Malignant neoplasm of small intestine (C17)

C17.8 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of overlapping sites of small intestine. The code C17.8 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 C17.8 might also be used to specify conditions or terms like adenocarcinoma of small intestine, gastrointestinal stromal neoplasm of overlapping lesion of small intestine, gastrointestinal stromal tumor of small intestine, overlapping malignant neoplasm of small intestine, primary adenocarcinoma of overlapping lesion of small intestine , primary adenocarcinoma of small intestine, etc.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: duodenojejunal junction or intestine, intestinal small overlapping lesion .

Approximate Synonyms

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code C17.8 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Table of Neoplasms

The code C17.8 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


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

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.
