Recurrent pterygium of eye, bilateral

This code signifies the presence of a pterygium that has regrown after previous removal, affecting both eyes. A pterygium is a benign, wedge-shaped growth of conjunctival tissue that extends onto the cornea. Its recurrence can lead to vision impairment, irritation, and cosmetic concerns.

Use this code when documentation clearly indicates a pterygium has reappeared in both eyes following prior surgical excision. The medical record should specify "recurrent" and "bilateral" to support its application. This code is appropriate for ongoing management or surgical intervention for recurrent bilateral pterygia.

• Ensure documentation explicitly states "recurrent" and "bilateral" to differentiate from primary or unilateral pterygium.
• Do not confuse with codes for primary pterygium (H11.00-H11.05) or pseudopterygium.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity being addressed.
