H11.013

What This Code Means

A pterygium is a growth of tissue on the eye's surface, and in this case, the growth is made of amyloid protein deposits and affects both eyes. This is a rare condition where abnormal protein accumulates in the wing-shaped tissue that grows across the cornea.

Coding Tips

• •Verify that the pterygium is confirmed to be amyloid type through pathology or clinical documentation before coding H11.013, as this is a specific histological diagnosis
• •Ensure bilateral involvement is documented in the medical record; if only one eye is affected, use H11.011 (right eye) or H11.012 (left eye) instead
