Poisoning by oth antidysrhythmic drugs, assault, subs encntr

This code signifies a poisoning event resulting from the intentional administration of an antidysrhythmic medication by another person with the intent to harm. The patient is presenting for follow-up care or treatment of lingering effects after the initial acute phase of the poisoning.

This code is appropriate when a patient is seen for ongoing management of complications or sequelae from an assault involving an antidysrhythmic drug. Examples include follow-up for cardiac arrhythmias, electrolyte imbalances, or organ damage that occurred due to the poisoning. It should be used after the initial encounter for the acute poisoning has been coded.

• Always assign an additional code for the specific antidysrhythmic drug if known.
• Ensure the documentation clearly states the poisoning was an assault and that this is a subsequent encounter.
• Do not use for accidental overdose or self-harm; those scenarios require different intent codes.
