C30.0

C30.0 — Malignant neoplasm of nasal cavity

Billable / specific codeICD-10-CM

C30.0 is a billable, specific ICD-10-CM code for malignant neoplasm of nasal cavity. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

malignant neoplasm of nasal bone (C41.0)
malignant neoplasm of nose NOS (C76.0)
malignant neoplasm of olfactory bulb (C72.2-)
malignant neoplasm of posterior margin of nasal septum and choana (C11.3)
malignant melanoma of skin of nose (C43.31)
malignant neoplasm of turbinates (C41.0)
other and unspecified malignant neoplasm of skin of nose (C44.301, C44.311, C44.321, C44.391)

Inclusion terms

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

Malignant neoplasm of cartilage of nose
Malignant neoplasm of nasal concha
Malignant neoplasm of internal nose
Malignant neoplasm of septum of nose
Malignant neoplasm of vestibule of nose

Other codes that can never be billed with C30.0

These codes carry an Excludes1 note pointing at C30.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C30.0 alone.

C41Malignant neoplasm of bone and articular cartilage of other and unspecified sites
C49Malignant neoplasm of other connective and soft tissue

Risk adjustment

C30.0 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

C30.0 is named in 66 Medicare coverage policies — 66 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
