Peripheral pterygium, stationary, left eye

This code signifies a non-progressive, benign growth of conjunctival tissue that extends onto the cornea in the left eye. This lesion typically originates from the nasal side and does not show signs of active enlargement or inflammation.

Apply this code when documentation specifies a pterygium in the left eye that is explicitly noted as "stationary" or "non-progressive." This typically occurs during routine eye examinations or follow-up visits for a previously diagnosed pterygium that is not actively growing.

• Ensure the documentation clearly specifies "stationary" or "non-progressive" to differentiate from progressive pterygium (H11.03-).
• Laterality is crucial; confirm the pterygium is in the left eye.
• Do not use this code if the pterygium is inflamed or showing signs of active growth, as this would indicate a different code.
