Hordeolum externum right lower eyelid

This code represents an external hordeolum, commonly known as a stye, located on the lower eyelid of the right eye. An external hordeolum is an acute bacterial infection of the glands of Zeis or Moll, presenting as a painful, red, and swollen lesion near the eyelid margin.

Apply this code when documentation clearly indicates a diagnosis of an external hordeolum affecting the right lower eyelid. This typically occurs after a physical examination confirming the characteristic localized inflammation and tenderness. Use this code for initial encounters and subsequent visits related to the management of this specific condition.

• Ensure laterality (right) and eyelid specificity (lower) are clearly documented to support this precise code.
• Differentiate from internal hordeolum (chalazion) or other eyelid inflammations; these have distinct codes.
• Do not use for unspecified hordeolum or hordeolum of other sites; specific codes exist for those presentations.
