ICD-10 Code H43.313 – Vitreous membranes and strands, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H43.313 – Vitreous membranes and strands, bilateral
What it is
This code identifies abnormal membranous strands or sheets in the vitreous humor of both eyes. It is used when the finding is documented as bilateral and not better explained by another vitreous disorder.
Clinical signs
Patients may report floaters, blurred vision, or visual disturbance, but clinical features vary; refer to documentation. Ophthalmic examination or imaging may note vitreous strands or membranes in both eyes.
When to use this code
Use H43.313 when the provider documents vitreous membranes or strands affecting both eyes. Choose it for a bilateral vitreous finding recorded on exam, imaging, or specialist assessment. If the note names a different vitreous condition, code that diagnosis instead.
Do not use for
Do not use this code for unilateral vitreous strands, floaters alone, or retinal disorders. If the record is unclear about laterality or the exact vitreous diagnosis, check documentation.
Coding tip
Confirm both the vitreous finding and bilateral laterality in the ophthalmology note before assigning H43.313.
