2021 ICD-10-CM Code D48.4

Neoplasm of uncertain behavior of peritoneum

Version 2021

Valid for Submission

D48.4 is a billable diagnosis code used to specify a medical diagnosis of neoplasm of uncertain behavior of peritoneum. The code D48.4 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.

The ICD-10-CM code D48.4 might also be used to specify conditions or terms like aggressive fibromatosis, extra-abdominal fibromatosis, leiomyomatosis peritonealis disseminata, mesothelioma of mesocolon, neoplasm of omentum , neoplasm of rectouterine pouch, etc.

The following anatomical sites found in the Table of Neoplasms apply to this 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

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code D48.4 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 D48.4 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


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.
