ICD-10 Code C69.61 – Malignant neoplasm of right orbit (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.61 – Malignant neoplasm of right orbit
What it is
C69.61 identifies a malignant tumor arising in the right orbit, the bony cavity that contains the eye and its supporting tissues. Use this code when the documentation specifies a primary cancer of the right orbital structures.
Clinical signs
Clinical features may include proptosis, eye pain, diplopia, decreased vision, or a visible orbital mass. Findings vary by tumor type and extent; refer to documentation.
When to use this code
Use C69.61 when the provider documents a malignant neoplasm of the right orbit, including a confirmed primary orbital cancer. It is also appropriate when the record clearly localizes the malignancy to the right orbital area. If the site is uncertain or only suspected, check documentation before coding.
Do not use for
Do not use this code for benign orbital tumors, inflammatory orbital disease, or cancers of the eyelid, conjunctiva, or globe. If the chart does not specify the right orbit, do not assume laterality.
Coding tip
Verify both malignancy and laterality in the pathology or provider note before assigning C69.61.
