Poisoning by coronary vasodilators, assault, sequela

This code indicates a long-term health problem or complication resulting from an intentional overdose or toxic exposure to a coronary vasodilator, such as nitroglycerin or isosorbide. The original poisoning event was an assault, meaning it was inflicted by another person with intent to harm. The sequela could manifest as chronic organ damage, neurological deficits, or other lasting effects.

Apply this code when documenting a patient presenting with a persistent condition directly attributable to a past assault involving poisoning by a coronary vasodilator. This is used for follow-up care or treatment of the chronic effects, not for the initial acute poisoning episode. Examples include chronic hypotension, persistent headaches, or organ dysfunction that developed after the initial assault.

• Always sequence this sequela code after the code for the specific manifestation of the sequela (e.g., chronic kidney failure).
• Ensure documentation clearly links the current condition to the past assault and the specific substance.
• Do not use this code for acute poisoning; refer to the appropriate acute poisoning codes for the initial event.
