ICD-10 Code H43.12 – Vitreous hemorrhage, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H43.12 – Vitreous hemorrhage, left eye
What it is
H43.12 identifies bleeding into the vitreous humor of the left eye. This code describes blood in the clear gel behind the lens, which can cloud vision and obscure the retina.
Clinical signs
Typical findings include sudden floaters, blurred vision, or a reddish haze in the affected eye. Clinical features vary; refer to documentation, especially if the exam notes reduced fundus view or vitreous blood.
When to use this code
Use H43.12 when the provider documents vitreous hemorrhage specifically in the left eye. It is appropriate for outpatient, emergency, or ophthalmology visits when laterality is stated and the hemorrhage is the reported diagnosis.
Code it when the record distinguishes the left eye from the right or bilateral eye. If the note only says “vitreous hemorrhage” without laterality, check documentation before assigning a laterality-specific code.
Do not use for
Do not use this code for hemorrhage in the retina, anterior chamber, or other eye structures. Avoid it when the documentation does not confirm vitreous involvement or left-eye laterality.
Coding tip
Always verify both the anatomic location and laterality in the ophthalmology note before coding H43.12.
