Code Classification

  • Neoplasms
    (C00–D49)
    • Malignant neoplasms of mesothelial and soft tissue
      (C45-C49)
      • Malignant neoplasm of other connective and soft tissue
        (C49)

C49.0 is a billable diagnosis code used to specify a medical diagnosis of malignant neoplasm of connective and soft tissue of head, face and neck. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic carotid (artery) ; Neoplasm, neoplastic cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] auricular ; Neoplasm, neoplastic cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] ear (external) ; Neoplasm, neoplastic cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] eyelid ; Neoplasm, neoplastic cartilage (articular) (joint) NEC [See Also: Neoplasm, bone] pinna ; Neoplasm, neoplastic connective tissue NEC auricle (ear) ; Neoplasm, neoplastic connective tissue NEC cervical region ; 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


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.

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
