ICD-10 Code H31.302 – Unspecified choroidal hemorrhage, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.302 – Unspecified choroidal hemorrhage, left eye
What it is
This code identifies bleeding in the choroid of the left eye when the record does not specify the cause or type. Use it for a documented choroidal hemorrhage limited to the left eye.
Clinical signs
Findings may include sudden visual disturbance, eye pain, or decreased vision, but clinical features vary; refer to documentation. Diagnosis is typically based on ophthalmic examination and imaging when recorded.
When to use this code
Use H31.302 when the provider documents a choroidal hemorrhage in the left eye and does not name a more specific subtype. It also fits when the note states “unspecified” or gives limited detail that still confirms the left eye.
If laterality is not documented, or the hemorrhage is described in another ocular layer, check documentation before coding. Code only when the chart clearly supports a choroidal source.
Do not use for
Do not use this code for hemorrhage in the right eye, both eyes, or when the site is different, such as vitreous or retinal bleeding. If the documentation is nonspecific, check documentation.
Coding tip
Always verify laterality and the exact anatomic site before assigning H31.302.
