Toxic effect of mercury and its compounds, assault, init

This code signifies a patient presenting with the initial adverse health effects resulting from mercury poisoning, specifically when the exposure was intentionally inflicted by another person. The toxic effects can range from neurological symptoms like tremors and cognitive impairment to kidney damage and gastrointestinal distress, depending on the form and dose of mercury.

Use this code for the initial encounter of a patient who has been deliberately poisoned with mercury or its compounds. This includes situations like attempted murder or intentional harm where mercury was the agent. It should be assigned when the patient is actively receiving treatment for the acute toxic effects.

• Always sequence this code first when it represents the primary reason for the encounter.
• Requires an additional code to specify the specific type of mercury compound, if known (e.g., T56.11- for organic mercury compounds).
• Do not use for accidental or unintentional mercury exposure; refer to codes for unintentional or undetermined intent.
