D37.4 - Neoplasm of uncertain behavior of colon

Version 2023
ICD-10:D37.4
Short Description:Neoplasm of uncertain behavior of colon
Long Description:Neoplasm of uncertain behavior of colon
Status: Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Neoplasms (C00–D48)
    • Neoplasms of uncertain behavior, polycythemia vera and myelodysplastic syndromes (D37-D48)
      • Neoplasm of uncrt behavior of oral cavity and dgstv organs (D37)

D37.4 is a billable ICD-10 code used to specify a medical diagnosis of neoplasm of uncertain behavior of colon. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis 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

Approximate Synonyms

Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

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.

Colonic 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:

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