ICD-10-CM Code C49.4

Malignant neoplasm of connective and soft tissue of abdomen

Version 2020 Replaced Code Billable Code Neoplasm Malignant Primary

Valid for Submission

C49.4 is a billable code used to specify a medical diagnosis of malignant neoplasm of connective and soft tissue of abdomen. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code C49.4 might also be used to specify conditions or terms like fibrosarcoma of spleen, malignant neoplasm of connective and soft tissue of abdomen, malignant neoplasm of connective and soft tissue of abdominal wall, malignant tumor of soft tissue of abdomen, neoplasm of blood vessel of abdomen, primary malignant neoplasm of blood vessel of abdomen, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: abdomen, abdominal wall [See Also: Neoplasm, abdomen, wall, skin] connective tissue ; adipose tissue [See Also: Neoplasm, connective tissue] ; aorta (thoracic) abdominal ; connective tissue NEC abdomen ; connective tissue NEC abdominal wall ; connective tissue NEC gastric ; connective tissue NEC gastrointestinal ; etc

  • C49.A5 - Gastrointestinal stromal tumor of rectum

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code C49.4:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Malignant neoplasm of abdominal wall

Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Fibrosarcoma of spleen

Diagnostic Related Groups

The ICD-10 code C49.4 is grouped in the following groups for version MS-DRG V37.0 What are Diagnostic Related Groups?
The Diagnostic Related Groups (DRGs) are a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC).
applicable from 10/01/2019 through 09/30/2020.

  • 542 - PATHOLOGICAL FRACTURES AND MUSCULOSKELETAL AND CONNECTIVE TISSUE MALIGNANCY WITH MCC
  • 543 - PATHOLOGICAL FRACTURES AND MUSCULOSKELETAL AND CONNECTIVE TISSUE MALIGNANCY WITH CC
  • 544 - PATHOLOGICAL FRACTURES AND MUSCULOSKELETAL AND CONNECTIVE TISSUE MALIGNANCY WITHOUT CC/MCC

  • Neoplasms (C00–D48)
    • Malignant neoplasms of mesothelial and soft tissue (C45-C49)

Code History

  • FY 2016 - New Code, effective from 10/1/2015 through 9/30/2016

Table of Neoplasms

The code C49.4 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


Cancer

Cancer begins in your cells, which are the building blocks of your body. Normally, your body forms new cells as you need them, replacing old cells that die. Sometimes this process goes wrong. New cells grow even when you don't need them, and old cells don't die when they should. These extra cells can form a mass called a tumor. Tumors can be benign or malignant. Benign tumors aren't cancer while malignant ones are. Cells from malignant tumors can invade nearby tissues. They can also break away and spread to other parts of the body.

Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for where they start. For example, lung cancer starts in the lung, and breast cancer starts in the breast. The spread of cancer from one part of the body to another is called metastasis. Symptoms and treatment depend on the cancer type and how advanced it is. Most treatment plans may include surgery, radiation and/or chemotherapy. Some may involve hormone therapy, immunotherapy or other types of biologic therapy, or stem cell transplantation.

Connective Tissue Disorders

Your connective tissue supports many different parts of your body, such as your skin, eyes, and heart. It is like a "cellular glue" that gives your body parts their shape and helps keep them strong. It also helps some of your tissues do their work. It is made of many kinds of proteins. Cartilage and fat are types of connective tissue.

Over 200 disorders that impact connective tissue. There are different types:

  • Genetic disorders, such as Ehlers-Danlos syndrome, Marfan syndrome, and osteogenesis imperfecta
  • Autoimmune disorders, such as lupus and scleroderma
  • Cancers, like some types of soft tissue sarcoma

Each disorder has its own symptoms and needs different treatment.
