ICD-10 Code H34.83 – Tributary (branch) retinal vein occlusion (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H34.83 – Tributary (branch) retinal vein occlusion
What it is
This code identifies obstruction of a branch retinal vein, which reduces blood drainage from part of the retina. It is used when the record states tributary or branch retinal vein occlusion.
Clinical signs
Typical findings include sudden painless vision loss or blurring in one eye, retinal hemorrhages, and macular edema. Clinical features vary; refer to documentation.
When to use this code
Use H34.83 when the provider documents branch or tributary retinal vein occlusion without a more specific site or laterality code. Apply it for confirmed retinal vein blockage affecting a branch vessel, including follow-up visits for the same diagnosis. Check documentation if the note is unclear.
Do not use for
Do not use this code for central retinal vein occlusion, retinal artery occlusion, or nonspecific visual complaints without documented vein occlusion. If the chart only says retinal vascular disease, check documentation.
Coding tip
Confirm laterality and any documented eye involvement before finalizing the code.
