ICD-10-CM Code C41.0

Malignant neoplasm of bones of skull and face

Version 2020 Billable Code Neoplasm Malignant Primary

Valid for Submission

C41.0 is a billable code used to specify a medical diagnosis of malignant neoplasm of bones of skull and face. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code C41.0 might also be used to specify conditions or terms like carcinoma of maxilla, chordoma of clivus, disorder of ethmoid bone, gnathic osteosarcoma, malignant neoplasm of bones of skull and face, malignant neoplasm of malar bone, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: alveolar ridge or process upper ; bone (periosteum) calvarium ; bone (periosteum) clivus ; bone (periosteum) cranial ; bone (periosteum) ethmoid (labyrinth) ; bone (periosteum) face ; bone (periosteum) frontal ; etc

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 guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code C41.0:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Malignant neoplasm of maxilla (superior)
  • Malignant neoplasm of orbital bone

Type 2 Excludes

Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

  • maxillary sinus C31.0
  • upper jaw C03.0
  • malignant neoplasm of jaw bone lower C41.1

Table of Neoplasms

The code C41.0 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.
