ICD-10 Code H31.309 – Unspecified choroidal hemorrhage, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H31.309 – Unspecified choroidal hemorrhage, unspecified eye
What it is
This code identifies bleeding in the choroid layer of the eye when the affected eye is not specified. Use it when documentation confirms choroidal hemorrhage but does not name the right or left eye.
Clinical signs
Findings may include sudden visual change, eye pain, or visible intraocular bleeding on examination. Clinical features vary; refer to documentation.
When to use this code
Use H31.309 when the provider documents choroidal hemorrhage without laterality and no more specific code is available. It is appropriate for ophthalmology notes, consults, or discharge summaries that identify the condition but omit the eye involved. Check documentation if the record is unclear.
Do not use for
Do not use this code when the hemorrhage is documented in a specific eye, or when the bleeding is in another ocular structure. Do not assign it if the record only says “eye hemorrhage” without choroidal involvement.
Coding tip
Look for laterality in the assessment, impression, or operative note before choosing this unspecified code.
