ICD-10-CM Code D37.4

Neoplasm of uncertain behavior of colon

Version 2021 Billable Code Neoplasm Uncertain Behavior

Valid for Submission

D37.4 is a billable code used to specify a medical diagnosis of neoplasm of uncertain behavior of colon. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code D37.4 might also be used to specify conditions or terms like carcinoid tumor of large intestine, neoplasm of hepatic flexure of colon, neoplasm of splenic flexure of colon, neoplasm of uncertain behavior of ascending colon, neoplasm of uncertain behavior of cecum, neoplasm of uncertain behavior of colon, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: Neoplasm, neoplastic caput coli ; Neoplasm, neoplastic cecum ; Neoplasm, neoplastic hepatic [See Also: Index to disease, by histology] flexure (colon) ; Neoplasm, neoplastic ileocecum, ileocecal (coil) (junction) (valve) ; Neoplasm, neoplastic intestine, intestinal large ; Neoplasm, neoplastic intestine, intestinal large caput coli ; Neoplasm, neoplastic intestine, intestinal large cecum ; etc

Table of Neoplasms

The code D37.4 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


Colonic Diseases

Also called: Large intestine diseases

Your colon, also known as the large intestine, is part of your digestive system. It's a long, hollow tube at the end of your digestive tract where your body makes and stores stool. Many disorders affect the colon's ability to work properly. Some of these include

  • Colorectal cancer
  • Colonic polyps - extra tissue growing in the colon that can become cancerous
  • Ulcerative colitis - ulcers of the colon and rectum
  • Diverticulitis - inflammation or infection of pouches in the colon
  • Irritable bowel syndrome - an uncomfortable condition causing abdominal cramping and other symptoms

Treatment for colonic diseases varies greatly depending on the disease and its severity. Treatment may involve diet, medicines and in some cases, surgery.
