ICD-10 Code C69.30 – Malignant neoplasm of unspecified choroid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.30 – Malignant neoplasm of unspecified choroid
What it is
This code identifies a malignant tumor arising in the choroid, the vascular layer of the eye, when the exact site is not further specified. Use it when documentation confirms choroidal cancer but does not name a more precise choroidal location.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings may include visual disturbance, blurred vision, or an incidental ocular mass noted on examination or imaging.
When to use this code
Use C69.30 when the provider documents a malignant neoplasm of the choroid and does not specify a more detailed choroidal subsite. It is appropriate for confirmed primary choroidal malignancy in the absence of a more specific location statement. If the record names a different ocular site, code that site instead.
Do not use for
Do not use this code for benign choroidal lesions, metastatic disease to the eye, or other intraocular sites such as the retina or ciliary body. Check documentation when the exact ocular primary site is unclear.
Coding tip
Query the provider if the record says only “eye cancer” or “ocular tumor” without confirming the choroid.
