Double pterygium of right eye

This code signifies the presence of two distinct pterygia affecting the right eye. A pterygium is a triangular growth of conjunctival tissue that extends onto the cornea, often associated with sun exposure. The "double" aspect indicates two separate growths on the same eye.

Apply this code when documentation clearly specifies the presence of two pterygia on the patient's right eye. This typically occurs in patients presenting with symptoms such as irritation, redness, or visual disturbance due to the corneal encroachment of these growths. The physician's notes should explicitly state "double pterygium" or describe two separate pterygial lesions on the right eye.

• Ensure documentation specifies "double" and the laterality (right eye) to support this specific code.
• Do not use this code for a single pterygium or for pterygia affecting the left or both eyes.
• Consider additional codes for any associated symptoms or complications, such as astigmatism (H52.2x) or corneal scarring (H17.x).
