Acute toxic conjunctivitis, left eye

This code signifies an acute inflammatory reaction of the conjunctiva in the left eye, specifically caused by exposure to a toxic substance. This condition typically presents with sudden onset of redness, irritation, and discharge due to chemical or irritant exposure.

Apply this code when documentation clearly indicates an acute conjunctivitis affecting the left eye, directly attributed to a toxic agent. This includes chemical splashes, fumes, or other irritant exposures.

• Ensure documentation specifies "acute" and identifies the "left eye."
• Do not use this code for allergic, bacterial, or viral conjunctivitis; those have distinct codes.
• Consider an external cause code (V00-Y99) to identify the toxic substance, if known and documented.
