Granular corneal dystrophy, right eye

This code signifies a specific form of corneal dystrophy affecting the right eye, characterized by the accumulation of granular deposits within the corneal stroma. These deposits can lead to corneal opacities, visual impairment, and recurrent erosions. It is a progressive, inherited disorder.

Use this code when documentation clearly indicates a diagnosis of granular corneal dystrophy specifically affecting the patient's right eye. This diagnosis is typically made based on slit-lamp examination findings and often confirmed by genetic testing. Supporting documentation should detail the presence of characteristic granular deposits.

• Ensure laterality is precisely documented; this code is specific to the right eye.
• Distinguish from other corneal dystrophies (e.g., lattice, macular) which have different ICD-10-CM codes.
• Consider co-reporting with codes for associated symptoms like visual impairment (H53.-) or corneal erosion (H16.2-) if documented.
