ICD-10 Code C69.60 – Malignant neoplasm of unspecified orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.60 – Malignant neoplasm of unspecified orbit
What it is
C69.60 identifies a malignant tumor arising in the orbit when the exact orbital site is not documented. Use it for cancer involving the eye socket area, but not for tumors clearly assigned to a more specific orbital location.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include orbital mass, eye displacement, swelling, pain, or visual disturbance, but the diagnosis must be supported by a provider’s statement of malignancy.
When to use this code
Use this code when the record states malignant neoplasm of the orbit and does not specify the exact orbital subsite. It also fits cases where pathology or imaging confirms malignancy, but the documentation remains nonspecific. If laterality or a more precise site is documented, code that specific option instead.
Do not use for
Do not use it for benign orbital tumors, inflammatory orbital disease, or metastases to the orbit unless the provider documents a primary malignant neoplasm of the orbit. Check documentation if the site is actually another eye or adnexal structure.
Coding tip
Confirm that “orbit” is documented as the primary malignant site and that no more specific orbital subsite is available before assigning C69.60.
