Edema of left orbit

This code signifies the presence of swelling or fluid accumulation within the soft tissues of the left eye socket. This edema can be a symptom of various underlying conditions affecting the orbital structures.

Apply this code when documentation explicitly states "edema of left orbit" or "orbital edema, left eye." This is appropriate for conditions such as orbital cellulitis, thyroid eye disease, or inflammatory pseudotumor affecting the left orbit.

• Ensure laterality is clearly documented (left, right, or bilateral) as distinct codes exist for each.
• Always code the underlying cause of the orbital edema if known and documented.
• Do not confuse with periorbital edema, which refers to swelling around the eye, not within the orbit itself.
