Poisoning by other agents primarily affecting skin and mucous membrane

This code signifies an adverse reaction to a substance that primarily manifests with dermatological or mucosal symptoms, such as rashes, burns, or irritation, due to accidental or intentional exposure. It covers systemic effects where the skin and mucous membranes are the dominant sites of injury.

Apply this code when documentation clearly indicates poisoning by a substance where the primary clinical presentation involves the integumentary system or mucous membranes. Examples include contact dermatitis from a chemical, chemical burns, or allergic reactions to substances affecting the skin and mouth. Documentation should specify the substance and the primary affected body systems.

• Always code the specific substance responsible for the poisoning using an E-code (E850-E869, E870-E879, E950-E952, E962.0-E962.1, E980-E982) in addition to this code.
• Distinguish from allergic reactions primarily affecting other systems (e.g., respiratory, cardiovascular) which would fall under different poisoning categories.
• Ensure the documentation supports "poisoning" rather than a simple adverse effect or side effect, which may require a different code from the 995 series.
