Pseudopterygium of conjunctiva, bilateral

This code signifies the presence of a pseudopterygium affecting both eyes. A pseudopterygium is a fold of conjunctiva that adheres to the cornea, typically at the limbus, but is not a true pterygium as it lacks the characteristic fibrovascular growth and is often a sequela of inflammation or trauma.

Apply this code when documentation explicitly states a diagnosis of pseudopterygium affecting both the right and left eyes. This is commonly seen following ocular injury, chemical burns, or chronic inflammatory conditions. Ensure the physician's notes clearly differentiate it from a true pterygium.

• Confirm laterality is explicitly documented as bilateral; otherwise, use unilateral codes.
• Distinguish carefully from true pterygium (H11.0-) as the underlying pathology and treatment may differ.
• Look for associated conditions or causes, such as chemical burns (T26.-) or other conjunctival disorders (H11.-), which may require additional coding.
