Recurrent pterygium of left eye

This code signifies the regrowth of a fleshy, wedge-shaped growth of conjunctival tissue onto the cornea of the left eye, following a previous surgical removal or natural regression. This recurrence can lead to vision impairment, irritation, and astigmatism.

Apply this code when documentation clearly indicates a pterygium has reappeared in the left eye after prior treatment. This is typically used for patients presenting with symptoms such as redness, foreign body sensation, or visual disturbance, and a physical exam confirms the recurrent growth.

• Ensure documentation specifies "recurrent" and clearly identifies the left eye.
• Distinguish from initial pterygium (H11.00-H11.05) or other conjunctival degenerations.
• Code any associated complications, such as corneal involvement, separately.
