Acute toxic conjunctivitis, bilateral

This code signifies an acute inflammatory response of the conjunctiva in both eyes, caused by exposure to a toxic substance. This condition typically presents with sudden onset of redness, irritation, tearing, and discharge, affecting both ocular surfaces simultaneously due to the irritant.

Apply this code when documentation clearly indicates bilateral conjunctivitis resulting from chemical or irritant exposure, such as fumes, splashes, or environmental toxins. Ensure the physician's notes specify the acute nature of the condition and its toxic etiology affecting both eyes.

• Differentiate from allergic conjunctivitis (H10.1-) or other infectious conjunctivitis (H10.0-, H10.3-) which have different etiologies.
• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral or unspecified eye code.
• If the specific toxic agent is known, consider an additional external cause code (e.g., T51-T65) to fully describe the circumstances.
