Poisn by unsp agents aff the cardiovasc sys, self-harm, init

This code signifies an adverse effect resulting from the deliberate ingestion or exposure to an unknown substance that primarily impacts the heart and circulatory system. The patient intentionally caused this harm to themselves, and this encounter represents the initial treatment for the poisoning.

Use this code when a patient presents with cardiovascular symptoms (e.g., arrhythmias, hypotension, cardiac arrest) due to a self-inflicted poisoning, and the specific toxic agent is not yet identified. This applies to the initial visit for evaluation and management of the acute poisoning event.

• Ensure documentation clearly states "intentional self-harm" and that the substance is "unspecified."
• Do not use if the specific substance is known; instead, code to the specific drug/substance.
• Append additional codes for specific cardiovascular manifestations or other injuries sustained.
