Vitreous degeneration, left eye

This code signifies a non-inflammatory deterioration of the vitreous humor within the left eye. This degeneration can involve liquefaction (synchysis) or condensation (syneresis) of the vitreous gel, leading to changes in its structure and clarity. It often manifests as floaters or flashes of light.

Apply this code when documentation specifies vitreous degeneration affecting only the left eye. This diagnosis is typically made during an ophthalmological examination, often supported by slit-lamp biomicroscopy findings. Use when the physician explicitly states "vitreous degeneration, left eye" or similar terminology.

• Ensure laterality is clearly documented as "left eye" to support this specific code.
• Do not use this code if the degeneration is secondary to another ocular condition, such as diabetic retinopathy or trauma; code the underlying condition first.
• Distinguish from vitreous hemorrhage (H43.1-) or other vitreous disorders (H43.89) which have distinct clinical presentations and codes.
