C41.0 — Malignant neoplasm of bones of skull and face
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.
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.
Risk adjustment
C41.0 risk-adjusts. Under the CMS-HCC V28 model it maps to this category:
- 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.
Medicare coverage
C41.0 is named in 70 Medicare coverage policies — 70 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
