Crystalline deposits in vitreous body, unspecified eye

This code signifies the presence of crystalline formations within the vitreous humor, the gel-like substance filling the posterior segment of the eye. These deposits can be composed of various substances, such as cholesterol (synchysis scintillans) or calcium-lipid complexes (asteroid hyalosis), and are typically observed during an ophthalmic examination. The "unspecified eye" designation indicates that the laterality of the condition is not documented.

Use this code when documentation confirms crystalline deposits in the vitreous body but does not specify whether the condition affects the right, left, or both eyes. This often occurs when the ophthalmologist notes the presence of the deposits without explicitly stating the affected eye(s) in the assessment or plan.

• Avoid using this code if the documentation specifies laterality (e.g., right eye, left eye, bilateral); instead, use the more specific codes for crystalline deposits in the right (H43.21), left (H43.22), or bilateral (H43.23) eyes.
• This code describes the presence of deposits, not the underlying cause or any associated visual impairment.
• Ensure the physician's notes clearly identify "crystalline deposits" or similar terminology (e.g., "asteroid hyalosis," "synchysis scintillans") within the vitreous.
