ICD-10 Code H43.312 – Vitreous membranes and strands, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H43.312 – Vitreous membranes and strands, left eye
What it is
Use this code for abnormal fibrous strands or membranes within the vitreous of the left eye. It identifies a localized vitreous finding, not a broader retinal or inflammatory disorder.
Clinical signs
Patients may report floaters, blurred vision, or visual distortion, but findings can be subtle. Clinical features vary; refer to documentation and ophthalmic examination results.
When to use this code
Use H43.312 when the provider documents vitreous membranes or strands specifically in the left eye. It fits ophthalmology notes, imaging reports, or exam findings that identify this left-sided vitreous abnormality. Check documentation if the record only mentions nonspecific vitreous changes.
Do not use for
Do not use this code for right eye, bilateral, or unspecified vitreous findings. It is also not the correct choice for retinal detachment, vitreous hemorrhage, or inflammatory eye disease unless separately documented.
Coding tip
Always match laterality exactly; if the left eye is not clearly stated, do not assign H43.312.
