Short Description: | Malig neoplm of conn and soft tiss of r low limb, inc hip |
Long Description: | Malignant neoplasm of connective and soft tissue of right lower limb, including hip |
Status: | Valid for Submission |
Version: | ICD-10-CM 2023 |
Code Classification: |
C49.21 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of connective and soft tissue of right lower limb, including hip. 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 the parent code C49.2 of the current diagnosis code given the correct histological behavior: Neoplasm, neoplastic aponeurosis plantar ; Neoplasm, neoplastic connective tissue NEC ankle ; Neoplasm, neoplastic connective tissue NEC calf ; Neoplasm, neoplastic connective tissue NEC extremity lower ; Neoplasm, neoplastic connective tissue NEC foot ; Neoplasm, neoplastic connective tissue NEC heel ; Neoplasm, neoplastic connective tissue NEC hip ; etc
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Malignant tumor of soft tissue of hip
- Primary angiosarcoma of right hip region
- Primary angiosarcoma of right lower limb

Table of Neoplasms
The parent code C49.2 of the current diagnosis 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
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.
