ICD-10 Code C69.4 – Malignant neoplasm of ciliary body (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.4 – Malignant neoplasm of ciliary body
What it is
C69.4 identifies a malignant tumor arising in the ciliary body, part of the eye’s uveal tract. Use it when documentation specifically states cancer of the ciliary body.
Clinical signs
Clinical features vary; refer to documentation. Findings may include an intraocular mass, visual disturbance, or signs noted on ophthalmic examination or imaging.
When to use this code
Use this code when the provider documents primary malignant neoplasm of the ciliary body. It may appear in ophthalmology notes, pathology reports, or oncology records. Code only when the site is clearly identified as the ciliary body.
Do not use for
Do not use it for benign ciliary body lesions, unspecified intraocular tumors, or malignancies documented in another eye structure. Check documentation if the anatomic site is unclear.
Coding tip
Verify laterality and exact tumor site in the record, because nearby uveal structures are coded differently.
