Poisoning by peripheral vasodilators, self-harm, init

This code signifies a patient presenting with adverse effects resulting from the deliberate overdose or misuse of peripheral vasodilators, with the explicit intent of self-harm. The patient is in the initial phase of treatment for this poisoning event. Peripheral vasodilators are medications that widen blood vessels, often used to treat conditions like peripheral artery disease or Raynaud's phenomenon.

Apply this code when documentation clearly indicates a patient intentionally ingested or administered an excessive amount of a peripheral vasodilator, leading to toxic effects. This is appropriate for the initial hospital visit or encounter where the poisoning is first evaluated and treated. Examples include emergency department admissions for overdose or initial inpatient stays for stabilization.

• Ensure documentation explicitly states "intentional self-harm" and identifies the substance as a peripheral vasodilator.
• Verify this is the initial encounter for the poisoning; subsequent encounters would use a different seventh character.
• Always code any associated manifestations of the poisoning (e.g., hypotension, tachycardia) in addition to this code.
