Central pterygium of right eye

This code describes a central pterygium affecting the right eye. A pterygium is a triangular growth of conjunctival tissue that extends onto the cornea, and in this specific case, it is located centrally, potentially impacting vision.

Use this code when documentation specifies a pterygium located centrally on the right eye. Supporting documentation should clearly indicate the laterality and the central location of the lesion, often noted during an ophthalmological examination.

• Differentiate from peripheral pterygium; location is key for accurate coding.
• Ensure laterality (right eye) is explicitly documented.
• Do not confuse with pinguecula, which is a yellow patch or bump on the conjunctiva that does not grow onto the cornea.
