C41.0 is a billable ICD code used to specify a diagnosis of malignant neoplasm of bones of skull and face. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code C41 is used to code Bone tumor

A bone tumor, (also spelled bone tumour), is a neoplastic growth of tissue in bone. Abnormal growths found in the bone can be either benign (noncancerous) or malignant (cancerous).

Malignant neoplasm of bones of skull and face, except mandible (exact match)

This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 170.0 was previously used, C41.0 is the appropriate modern ICD10 code.

Parent Code: C41 - Malignant neoplasm of bone and articular cartilage of other and unspecified sites
