Poisoning by other antidysrhythmic drugs, assault, sequela

This code indicates a patient is experiencing the long-term effects of being intentionally poisoned by an antidysrhythmic medication. The poisoning was a result of an assault, meaning it was inflicted by another person with malicious intent. The patient is no longer in the acute phase of the poisoning but is dealing with residual health issues.

Use this code when documenting a patient presenting with chronic or residual health problems directly attributable to a past assault involving an antidysrhythmic drug. This applies to follow-up visits where the sequelae of the poisoning are being managed, rather than the initial acute poisoning event. The intent of the poisoning must be clearly documented as an assault.

• Ensure documentation clearly states the poisoning was an assault and that the patient is being treated for sequelae, not the acute event.
• Always code the specific manifestation(s) of the sequela first, then this code as a secondary diagnosis.
• Verify the substance involved is an "other antidysrhythmic drug" and not a more specific type.
