Hordeolum internum right upper eyelid

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A painful infection or swelling of the inner eyelid structures on the right upper eyelid, typically involving the meibomian glands.

Coding Tips

  • •Hordeolum internum affects internal eyelid structures (meibomian glands); this is more serious than external hordeolum
  • •Ensure both laterality (right eye) and eyelid location (upper) are clearly documented in the medical record
