Long Description:Malignant neoplasm of bone and articular cartilage of other and unspecified sites

Code Classification

  • Neoplasms (C00–D48)
    • Malignant neoplasms of bone and articular cartilage (C40-C41)
      • Malignant neoplasm of bone/artic cartl of and unsp sites (C41)

C41 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 bone and articular cartilage of other and unspecified sites. The code is not specific and is NOT valid for the year 2022 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.

Unspecified diagnosis codes like C41 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Specific Coding for Malignant neoplasm of bone/artic cartl of and unsp sites

Non-specific codes like C41 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 bone/artic cartl of and unsp sites:

  • BILLABLE CODE - Use C41.0 for Malignant neoplasm of bones of skull and face
  • BILLABLE CODE - Use C41.1 for Malignant neoplasm of mandible
  • BILLABLE CODE - Use C41.2 for Malignant neoplasm of vertebral column
  • BILLABLE CODE - Use C41.3 for Malignant neoplasm of ribs, sternum and clavicle
  • BILLABLE CODE - Use C41.4 for Malignant neoplasm of pelvic bones, sacrum and coccyx
  • BILLABLE CODE - Use C41.9 for Malignant neoplasm of bone and articular cartilage, unspecified

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 coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code C41:


Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

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.
