ICD-10 Code H43.393 – Other vitreous opacities, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H43.393 – Other vitreous opacities, bilateral
What it is
H43.393 identifies abnormal opacities in the vitreous of both eyes. These are commonly described as floaters or visible spots in the visual field.
Clinical signs
Patients may report moving specks, cobwebs, or shadows that shift with eye movement. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents bilateral vitreous opacities or bilateral floaters without a more specific vitreous disorder. It fits routine ophthalmology findings when both eyes are affected. Check documentation if the note also mentions retinal tear, hemorrhage, or detachment.
Do not use for
Do not use this code for unilateral vitreous opacities or when a different vitreous condition is documented. Do not assign it if the finding is better explained by retinal disease or vitreous hemorrhage.
Coding tip
Confirm that the documentation clearly states bilateral involvement before selecting H43.393.
