2021 ICD-10-CM Code C40.2

Malignant neoplasm of long bones of lower limb

Version 2021

Not Valid for Submission

C40.2 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of malignant neoplasm of long bones of lower limb. The code is not specific and is NOT valid for the year 2021 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: Neoplasm, neoplastic bone (periosteum) femur (any part) ; Neoplasm, neoplastic bone (periosteum) fibula (any part) ; Neoplasm, neoplastic bone (periosteum) knee ; Neoplasm, neoplastic bone (periosteum) leg NEC ; Neoplasm, neoplastic bone (periosteum) limb NEC lower (long bones) ; Neoplasm, neoplastic bone (periosteum) patella ; Neoplasm, neoplastic bone (periosteum) tibia (any part) ; etc

Code Classification

Specific Coding for Malignant neoplasm of long bones of lower limb

Non-specific codes like C40.2 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for malignant neoplasm of long bones of lower limb:

  • BILLABLE CODE - Use C40.20 for Malignant neoplasm of long bones of unspecified lower limb
  • BILLABLE CODE - Use C40.21 for Malignant neoplasm of long bones of right lower limb
  • BILLABLE CODE - Use C40.22 for Malignant neoplasm of long bones of left lower 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 C40.2 are found in the index:

Table of Neoplasms

The code C40.2 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:

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.
