Edema of right orbit

This code signifies the accumulation of excess fluid within the soft tissues surrounding the right eyeball, leading to swelling of the right orbital region. This can manifest as periorbital puffiness or proptosis, indicating an underlying inflammatory, infectious, or systemic process affecting the right eye socket.

Apply this code when documentation explicitly states "edema of right orbit" or describes swelling localized to the right eye socket. Supporting clinical notes should detail the laterality and the nature of the swelling, often in the context of conditions like orbital cellulitis, thyroid eye disease, or allergic reactions affecting the right eye.

• Ensure laterality is clearly documented; differentiate from bilateral or unspecified orbital edema.
• Do not confuse with periorbital edema (H05.21-) which is swelling around the orbit, not necessarily within it.
• Always code the underlying cause of the orbital edema first, if known and documented.
