ICD-10 Code H43.311 – Vitreous membranes and strands, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H43.311 – Vitreous membranes and strands, right eye
What it is
H43.311 identifies abnormal fibrous strands or membranes within the vitreous of the right eye. These changes are documented as a right-eye vitreous disorder, not a retinal or lens condition.
Clinical signs
Patients may report floaters, blurred vision, or visual disturbance, but clinical features vary; refer to documentation. Ophthalmic examination may note vitreous opacities or strands in the right eye.
When to use this code
Use this code when the provider documents vitreous membranes or strands specifically in the right eye. It fits cases where the finding is the reason for evaluation or is clearly recorded in the assessment.
Choose the laterality-specific code only when the right eye is stated. If the note says bilateral, left eye, or does not specify laterality, check documentation before coding.
Do not use for
Do not use H43.311 for retinal tears, vitreous hemorrhage, or nonspecific floaters unless the record specifically supports vitreous membranes or strands. Do not assume laterality if it is not documented.
Coding tip
Confirm that the ophthalmology note names “membranes” or “strands” and identifies the right eye before assigning H43.311.
