Conjunctival edema, right eye

This code signifies swelling or fluid accumulation in the conjunctiva, the clear membrane lining the inside of the eyelids and covering the white part of the eye, specifically affecting the right eye. It indicates an inflammatory or allergic response causing the conjunctiva to appear puffy or watery.

Apply this code when documentation clearly indicates edema of the conjunctiva in the right eye. This can be observed in cases of allergic conjunctivitis, chemical irritation, or post-surgical swelling. Supporting documentation should include physician notes detailing the presence and location of conjunctival edema.

• Ensure laterality is clearly documented (right eye). If both eyes are affected, a bilateral code or separate codes for each eye would be appropriate.
• Do not confuse with codes for conjunctival hyperemia (redness) without edema.
• Consider coding any underlying cause or associated conditions, such as allergic conjunctivitis (H10.1xx) or chemical burns (T26.x), as primary or secondary diagnoses.
