Crystalline deposits in vitreous body, right eye

This code describes the presence of crystalline deposits within the vitreous humor of the right eye. These deposits, often cholesterol crystals (synchysis scintillans) or calcium-lipid complexes (asteroid hyalosis), are typically benign and do not significantly impair vision.

Use this code when documentation explicitly states crystalline deposits are observed in the vitreous of the right eye. This is often an incidental finding during a dilated fundus examination or slit lamp biomicroscopy. The physician's note should specify the laterality.

• Ensure the documentation specifies "right eye" for accurate laterality coding.
• Do not confuse with vitreous opacities not explicitly described as crystalline.
• If bilateral, a separate code for the left eye (H43.22) and an unspecified code (H43.23) may also be applicable depending on documentation.
