D48.4 - Neoplasm of uncertain behavior of peritoneum

Version 2023
ICD-10:D48.4
Short Description:Neoplasm of uncertain behavior of peritoneum
Long Description:Neoplasm of uncertain behavior of peritoneum
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 uncertain behavior of other and unsp sites (D48)

D48.4 is a billable ICD-10 code used to specify a medical diagnosis of neoplasm of uncertain behavior of peritoneum. 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 cavity peritoneal ; Neoplasm, neoplastic cul-de-sac (Douglas') ; Neoplasm, neoplastic Douglas' cul-de-sac or pouch ; Neoplasm, neoplastic mesentery, mesenteric ; Neoplasm, neoplastic mesoappendix ; Neoplasm, neoplastic mesocolon ; Neoplasm, neoplastic omentum ; etc

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.

Patient Education


Peritoneal Disorders

Your peritoneum is the tissue that lines your abdominal wall and covers most of the organs in your abdomen. A liquid, peritoneal fluid, lubricates the surface of this tissue.

Disorders of the peritoneum are not common. They include:

Your doctor may use imaging tests or lab tests to analyze the peritoneal fluid to diagnose the problem. Treatment of peritoneal disorders depends on the cause.
