ICD-10-CM Code C40.9

Malignant neoplasm of unspecified bones and articular cartilage of limb

Version 2020 Non-Billable Code Neoplasm Malignant Primary

Not Valid for Submission

C40.9 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of malignant neoplasm of unspecified bones and articular cartilage of limb. The code is NOT valid for the year 2020 for the submission of HIPAA-covered transactions.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: bone (periosteum) limb NEC .

ICD-10:C40.9
Short Description:Malignant neoplasm of unsp bones and artic cartilage of limb
Long Description:Malignant neoplasm of unspecified bones and articular cartilage of limb

Consider the following ICD-10 codes with a higher level of specificity:

  • C40.90 - Malignant neoplasm of unspecified bones and articular cartilage of unspecified limb
  • C40.91 - Malignant neoplasm of unspecified bones and articular cartilage of right limb
  • C40.92 - Malignant neoplasm of unspecified bones and articular cartilage of left limb

Index to Diseases and Injuries

The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for the code C40.9 are found in the index:

Table of Neoplasms

The code C40.9 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


Bone Cancer

Cancer that starts in a bone is uncommon. Cancer that has spread to the bone from another part of the body is more common.

There are three types of bone cancer:

  • Osteosarcoma - occurs most often between ages 10 and 19. It is more common in the knee and upper arm.
  • Chondrosarcoma - starts in cartilage, usually after age 40
  • Ewing's sarcoma - occurs most often in children and teens under 19. It is more common in boys than girls.

The most common symptom of bone cancer is pain. Other symptoms vary, depending on the location and size of the cancer. Surgery is often the main treatment for bone cancer. Other treatments may include amputation, chemotherapy, and radiation therapy. Because bone cancer can come back after treatment, regular follow-up visits are important.
