Vitreous membranes and strands, left eye

This code describes the presence of abnormal fibrous structures or strands within the vitreous humor of the left eye. These membranes or strands can be congenital, age-related, or result from inflammation, trauma, or previous ocular surgery, potentially affecting vision.

Use this code when documentation specifies vitreous membranes or strands are present in the left eye. This diagnosis is typically made during an ophthalmologic examination, often with slit-lamp biomicroscopy or B-scan ultrasonography, identifying the specific eye affected.

• Ensure the documentation clearly specifies "left eye" to support this laterality.
• Distinguish from vitreous opacities (H43.39-) or vitreous hemorrhage (H43.1-) if the documentation describes a different condition.
• Code any underlying cause or associated conditions, such as diabetic retinopathy or posterior vitreous detachment, if documented.
