Poisoning by antithyroid drugs, assault, initial encounter

This code signifies a patient presenting with adverse effects resulting from the intentional administration of antithyroid medications by another person with the intent to harm. The poisoning is due to the pharmacological action of the drug, not an allergic reaction or side effect from appropriate therapeutic use.

Apply this code when documentation clearly indicates a patient has been poisoned by antithyroid drugs in the context of an assault. This includes situations where the drug was forcibly administered or given without the patient's knowledge or consent with malicious intent. This specific code is for the initial encounter for this poisoning event.

• Ensure documentation explicitly states "assault" or similar language indicating intentional harm by another party.
• Verify the substance involved is an antithyroid drug; do not use for other drug classes.
• Confirm this is the initial encounter for the poisoning; subsequent care would use a different seventh character.
