Recurrent erosion of cornea, right eye

This code describes the repeated breakdown and loss of the outermost layer of the cornea (epithelium) in the right eye. This condition typically results in sudden, severe eye pain, foreign body sensation, and photophobia, often upon awakening. It is characterized by the failure of the corneal epithelium to adhere properly to the underlying Bowman's layer.

Use this code when documentation clearly indicates a history of recurrent corneal erosions affecting the patient's right eye. This diagnosis is supported by ophthalmological examination findings such as epithelial defects, loose epithelium, or a history of previous erosive episodes in the specified eye. It is appropriate for both initial diagnosis and subsequent encounters for management of this chronic condition.

• Ensure laterality is accurately documented and coded; differentiate between right, left, and bilateral involvement.
• Distinguish from acute corneal abrasion (T26.01XA) or other non-recurrent corneal defects.
• Consider coding any underlying causes, such as corneal dystrophy (e.g., H18.5x), if documented.
