Crystalline deposits in vitreous body, bilateral

This code signifies the presence of crystalline deposits within the vitreous humor of both eyes. These deposits, often appearing as sparkling or shimmering particles, are typically cholesterol crystals (synchysis scintillans) or calcium-lipid complexes (asteroid hyalosis). While often asymptomatic, they can sometimes cause visual disturbances.

Use this code when documentation explicitly states the presence of crystalline deposits in the vitreous body of both eyes. This diagnosis is typically made during an ophthalmological examination, such as a slit-lamp examination or fundoscopy. Documentation should clearly specify the bilateral involvement.

• Ensure the documentation specifies bilateral involvement; separate codes exist for unilateral involvement.
• Do not confuse with vitreous opacities that are not crystalline in nature (e.g., vitreous hemorrhage, inflammatory cells).
• Code any underlying systemic conditions contributing to the deposits (e.g., diabetes, hyperlipidemia) as additional diagnoses.
