Amyloid pterygium of right eye

This code describes a specific type of pterygium affecting the right eye, characterized by the deposition of amyloid protein. Pterygium is a benign, wedge-shaped growth of the conjunctiva that extends onto the cornea, and in this case, it has an amyloid component. This condition can cause irritation, foreign body sensation, and potentially impair vision if it encroaches on the visual axis.

Use this code when documentation explicitly states "amyloid pterygium" affecting the right eye. This diagnosis is typically made based on clinical examination and may be confirmed by biopsy if there's suspicion of amyloid deposition. Ensure the laterality (right eye) is clearly documented.

• Distinguish from other types of pterygium (e.g., recurrent, unspecified) which have different codes.
• Confirm the laterality; separate codes exist for the left eye and bilateral involvement.
• Look for documentation of biopsy results or specific ophthalmological findings confirming amyloidosis.
