Peripheral pterygium, stationary, right eye

This code describes a non-progressive, benign growth of conjunctival tissue that extends onto the cornea in the right eye. This fleshy, wedge-shaped lesion typically originates from the nasal side of the conjunctiva. "Stationary" indicates that the pterygium is not actively growing or encroaching further onto the cornea.

Use this code for patients diagnosed with a pterygium in their right eye that is documented as stable and not showing signs of progression. This diagnosis is often made during routine ophthalmic examinations or when a patient presents with mild irritation or cosmetic concerns related to the lesion. Documentation should clearly specify "right eye" and "stationary" or "non-progressive."

• Ensure documentation explicitly states "right eye" and "stationary" or "non-progressive" to support this specific code.
• Do not use this code if the pterygium is documented as progressive, recurrent, or inflamed; separate codes exist for those conditions.
• Be mindful of laterality; codes for the left eye (H11.042) and bilateral (H11.043) are distinct.
