Billable / specific codeICD-10-CM

C41.0 is a billable, specific ICD-10-CM code for malignant neoplasm of bones of skull and face. It is valid for submission on a claim.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • carcinoma, any type except intraosseous or odontogenic of:
  • maxillary sinus (C31.0)
  • upper jaw (C03.0)
  • malignant neoplasm of jaw bone (lower) (C41.1)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Malignant neoplasm of maxilla (superior)
  • Malignant neoplasm of orbital bone

Other codes that can never be billed with C41.0

These codes carry an Excludes1 note pointing at C41.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C41.0 alone.

  • C69.6Malignant neoplasm of orbit
  • C30.0Malignant neoplasm of nasal cavity
  • C30.1Malignant neoplasm of middle ear

Risk adjustment

  • HCC 21 Lymphoma and Other Cancers0.671 RAF

Coefficient shown for the Community Non-dual Aged segment. A higher HCC in the same hierarchy will suppress this one, so capturing it does not always add score.
