Pseudopterygium of conjunctiva, unspecified eye

This code describes a pseudopterygium, which is a fold of conjunctiva that adheres to the cornea, typically at the limbus, but is not a true pterygium. Unlike a pterygium, a pseudopterygium is usually a sequela of inflammation or trauma and does not have the characteristic triangular shape or progressive growth pattern. This specific code is used when the affected eye is not specified in the clinical documentation.

Use this code when documentation indicates a diagnosis of pseudopterygium of the conjunctiva, and the laterality (right or left eye) is not explicitly stated. This often occurs in cases where the condition is noted without specific detail on the affected eye, or when it's a bilateral condition not separately documented for each eye. Supporting documentation would include an ophthalmologist's or optometrist's notes confirming the presence of a pseudopterygium.

• Avoid using this code if the laterality is documented; instead, choose the specific code for the right (H11.811) or left (H11.812) eye.
• Differentiate carefully between pseudopterygium and true pterygium (H11.0-); pseudopterygium is typically a scar from previous inflammation or injury.
• Ensure the documentation clearly states "pseudopterygium" to avoid confusion with other conjunctival lesions.
