ICD-10 Code C69.41 – Malignant neoplasm of right ciliary body (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.41 – Malignant neoplasm of right ciliary body
What it is
This code identifies a malignant tumor arising in the ciliary body of the right eye. It tells you the cancer is located in that specific ocular structure, not elsewhere in the eye.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note an intraocular mass, visual disturbance, pain, or findings on ophthalmic examination or imaging supporting a malignant ciliary body lesion.
When to use this code
Use C69.41 when the provider documents a malignant neoplasm specifically in the right ciliary body. Apply it for confirmed primary ocular cancer, or when the diagnosis is stated clearly in the assessment.
Do not infer laterality or site from general eye cancer wording. If the note says only “eye malignancy” or another ocular location, check documentation before assigning this code.
Do not use for
Do not use this code for benign ciliary body lesions, metastatic disease to the eye without a primary ciliary body tumor, or unspecified eye cancer. Check documentation when the site or laterality is unclear.
Coding tip
Verify both the exact anatomic site and right-sided laterality before coding, because ocular neoplasms are coded by location and eye side.
