ICD-10 Code C69.20 – Malignant neoplasm of unspecified retina (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C69.20 – Malignant neoplasm of unspecified retina
What it is
C69.20 identifies a malignant tumor arising in the retina when the specific retinal site is not documented. Use it for primary retinal cancer cases where the chart does not specify a more exact location.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include visual changes, leukocoria, or an intraocular mass on examination or imaging, but you should code only what is confirmed in the record.
When to use this code
Use this code when the provider documents malignant neoplasm of the retina and does not name a more specific retinal subsite. It is appropriate for confirmed primary retinal malignancy in the unspecified eye or unspecified retinal location. Check documentation if the laterality or exact site is unclear.
Do not use for
Do not use C69.20 for benign retinal lesions, metastatic eye disease, or tumors documented in a different ocular structure. If the record identifies a more specific retinal site or another eye code, use that instead.
Coding tip
Query for laterality and exact retinal location when the note says only “retinal cancer” or “malignant retinal neoplasm.”
