Serous conjunctivitis, except viral, left eye

This code signifies inflammation of the conjunctiva, characterized by a watery discharge, affecting the left eye. It specifically excludes cases where a viral etiology has been identified or is suspected.

Apply this code when documentation indicates serous conjunctivitis in the left eye, and the provider has ruled out a viral cause or has not identified one. This is appropriate for allergic conjunctivitis, irritant conjunctivitis, or other non-viral causes presenting with serous discharge.

• Ensure documentation clearly specifies "left eye" and "serous" discharge.
• Do not use if the documentation indicates a viral cause; instead, refer to codes in the H10.21- series.
• Consider additional codes for underlying causes, such as allergic rhinitis (J30.-) if applicable.
