Recurrent pterygium of unspecified eye

This code signifies the regrowth of a fleshy, wedge-shaped growth of conjunctival tissue onto the cornea after surgical removal. This recurrence can impair vision and cause irritation, redness, and foreign body sensation.

Use this code when documentation clearly indicates a pterygium has reappeared in an unspecified eye following a previous excision. This diagnosis is appropriate when the laterality of the recurrence is not specified in the medical record.

• Ensure the documentation explicitly states "recurrent" pterygium.
• Avoid using this code if the laterality (right, left, or bilateral) is documented; instead, use the more specific codes for recurrent pterygium.
• Do not confuse with initial pterygium diagnoses (H11.00-H11.05-).
