Acid chemical burn of cornea and conjunctival sac

This code signifies an ocular injury resulting from exposure to an acidic chemical substance, affecting both the transparent outer layer of the eye (cornea) and the membrane lining the eyelids and covering the white part of the eye (conjunctival sac). The burn can range in severity, leading to pain, vision impairment, and potential long-term damage.

Apply this code when documentation clearly indicates a chemical burn to the eye caused by an acidic agent, specifically impacting the cornea and conjunctiva. This is typically supported by physician notes detailing the mechanism of injury, the chemical involved (if known to be acidic), and the affected ocular structures.

• Differentiate from alkaline chemical burns, which have a separate code and different clinical implications.
• Ensure the documentation specifies "acid" as the chemical agent; otherwise, an unspecified chemical burn code may be more appropriate.
• Consider sequencing this code with an external cause code (E-code) to identify the circumstances of the injury.
