C69.6 — Malignant neoplasm of orbit
C69.6 is a non-billable header ICD-10-CM code for malignant neoplasm of orbit. It cannot be billed on its own: choose one of the more specific child codes below.
Excludes1 — never code together
These conditions cannot occur together. Billing both on the same encounter is a denial.
- malignant neoplasm of orbital bone (C41.0)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Malignant neoplasm of connective tissue of orbit
- Malignant neoplasm of extraocular muscle
- Malignant neoplasm of peripheral nerves of orbit
- Malignant neoplasm of retrobulbar tissue
- Malignant neoplasm of retro-ocular tissue
Excludes1 inherited from the categories above C69.6
These are not written on C69.6, but they bind it: a note on a category applies to every code beneath it. Billing C69.6 with anything listed here is a denial.
Other codes that can never be billed with C69.6
These codes carry an Excludes1 note pointing at C69.6. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading C69.6 alone.
Risk adjustment
C69.6 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
Code history
C69.6 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.
