Toxic effect of unsp inorganic substance, undetermined, init

This code signifies a harmful reaction to an unknown inorganic substance where the intent (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is presenting for the initial treatment of this toxic effect.

Apply this code when a patient exhibits symptoms of poisoning from an inorganic substance, but the specific substance is not identified, and the circumstances surrounding the exposure are unclear. This is appropriate for the first visit related to this particular toxic event.

• Ensure the documentation explicitly states "unspecified inorganic substance" and "undetermined intent."
• Only use for the initial encounter for treatment of the poisoning. Subsequent care would use a different encounter character.
• Avoid using this code if a more specific substance or intent can be identified; always strive for the highest level of specificity.
