What This Code Means
A pterygium is a growth of tissue on the white part of the eye that extends toward the cornea (the clear front part of the eye). This code specifically refers to a pterygium located in the central area of the right eye.
Coding Tips
- •Verify laterality is documented as right eye; if bilateral pterygia are present, code both H11.021 (right) and H11.022 (left) separately
- •Confirm whether the pterygium is affecting vision or causing symptoms, as this may influence treatment decisions and documentation specificity
