Edema of right upper eyelid

This code signifies the presence of swelling or fluid accumulation specifically in the upper eyelid of the right eye. It indicates a localized inflammatory or fluid imbalance process affecting this particular anatomical structure.

Use this code when documentation clearly specifies edema affecting the right upper eyelid. This often occurs in cases of allergic reactions, localized inflammation, infection (e.g., preseptal cellulitis), or trauma. The physician's notes should explicitly mention "edema" and "right upper eyelid."

• Ensure the documentation specifies "upper" eyelid; do not use for generalized eyelid edema or lower eyelid involvement.
• Always code the underlying cause of the edema if known and documented (e.g., allergic conjunctivitis, cellulitis).
• Distinguish from blepharitis (inflammation of the eyelid margins) or chalazion/hordeolum, which have distinct codes.
