Hordeolum externum left eye, unspecified eyelid

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

What This Code Means

A painful bump or infection on the outer edge of the left eyelid, typically caused by a blocked oil gland or hair follicle.

Coding Tips

  • •Hordeolum externum affects the external structures (lash follicles or glands of Zeis/Moll); ensure laterality (left eye) is documented
  • •When eyelid location is unspecified, use the 'unspecified eyelid' code rather than guessing upper or lower
