This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
Drooping of the left eyelid caused by weakness or disease of the eyelid muscle itself.
Coding Tips

- •Ensure documentation clearly indicates left eyelid involvement to distinguish from bilateral or right-sided cases
