Edema of left lower eyelid

This code signifies the presence of swelling or fluid retention specifically affecting the lower eyelid of the left eye. It indicates a localized accumulation of interstitial fluid, leading to visible puffiness or distension of the left lower eyelid tissue.

Use this code when documentation clearly specifies edema of the left lower eyelid. This may be observed in conditions such as allergic reactions, inflammatory processes, trauma, or systemic conditions manifesting with localized periorbital swelling. The medical record should explicitly state "edema" and "left lower eyelid."

• Ensure laterality is precisely documented (left vs. right).
• Distinguish from generalized periorbital edema, which would use a different code.
• Code any underlying cause of the edema if known and documented.
