Lattice corneal dystrophy, right eye

This code describes a rare, inherited eye disorder affecting the cornea, specifically the right eye. Lattice corneal dystrophy is characterized by the accumulation of abnormal protein fibers (amyloid) within the corneal stroma, leading to a lattice-like pattern visible upon examination. This can cause recurrent corneal erosions, pain, and progressive vision impairment.

Use this code when documentation confirms a diagnosis of lattice corneal dystrophy affecting the patient's right eye. This diagnosis is typically made by an ophthalmologist based on slit-lamp examination findings. Supporting documentation should clearly specify the type of corneal dystrophy and the affected eye.

• Ensure laterality is accurately documented and coded; differentiate between right, left, and bilateral involvement.
• Do not confuse with other types of corneal dystrophies (e.g., granular, macular) which have distinct ICD-10-CM codes.
• Consider additional codes for associated symptoms or complications, such as corneal erosion (e.g., H16.00-).
