Poisn by oth agents aff the cardiovasc sys, self-harm, subs

This code signifies a poisoning event involving substances that primarily impact the heart and blood vessels, where the patient intentionally caused the harm to themselves. It is used when the patient is receiving active treatment for the sequelae of the poisoning, or for complications arising from it, after the initial encounter. The focus is on the cardiovascular system's involvement due to the toxic agent.

Use this code for follow-up encounters when a patient is being treated for cardiovascular complications (e.g., arrhythmias, heart failure, hypotension) resulting from an intentional self-poisoning. This applies to situations where the patient is no longer in the acute phase of the poisoning but is still under care for its effects. Examples include ongoing management of drug-induced cardiomyopathy or persistent dysrhythmias following an overdose.

• Ensure the documentation clearly states intentional self-harm and that the primary system affected is cardiovascular.
• This "D" seventh character indicates a subsequent encounter, meaning the patient is receiving ongoing care for the poisoning's effects.
• Always code the specific substance(s) involved in the poisoning using the appropriate T-code for toxic effect, if known.
