ICD-10 Code C69.3 – Malignant neoplasm of choroid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.3 – Malignant neoplasm of choroid
What it is
C69.3 identifies a malignant tumor arising in the choroid, the vascular layer of the eye behind the retina. Use it when documentation states choroidal cancer or a malignant choroidal neoplasm.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include a choroidal mass on ocular examination or imaging, with possible visual disturbance, flashes, floaters, or visual field changes.
When to use this code
Use C69.3 when the provider documents a primary malignant neoplasm of the choroid. It may also apply when the diagnosis is confirmed by ophthalmology, pathology, or imaging and the site is clearly choroidal. Code the documented laterality or associated extension only if the record supports it.
Do not use for
Do not use this code for benign choroidal lesions, metastatic disease to the choroid, or other intraocular sites such as the retina or ciliary body. Check documentation if the primary site is unclear.
Coding tip
Verify the exact ocular site in the note, because eye malignancies are coded by specific anatomic location.
