BillableHordeolum externum right upper eyelid
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
A hordeolum externum is a painful, pus-filled bump on the outer edge of the upper eyelid, usually caused by a bacterial infection of the hair follicle or sweat gland. This code specifically identifies the infection occurring on the right upper eyelid.
Coding Tips
- •Verify laterality (right vs. left) and eyelid location (upper vs. lower) in the documentation before assigning the code, as these are essential specificity requirements
- •Distinguish between hordeolum externum (external stye affecting eyelash follicles) and hordeolum internum (internal stye affecting meibomian glands) as they have different code assignments
