Poisoning by peripheral vasodilators, self-harm, sequela

This code signifies a long-term health problem or condition resulting from a deliberate overdose or misuse of medications intended to widen blood vessels, such as nitrates or calcium channel blockers. The initial act of self-harm has already occurred, and the patient is now presenting with a residual effect directly attributable to that poisoning.

Apply this code when documenting a patient presenting with chronic organ damage, neurological deficits, or other lasting health issues that are a direct consequence of a past intentional self-poisoning with peripheral vasodilators. This would be used after the acute phase of the poisoning has resolved, and the patient is being treated for the sequelae.

• Always sequence this code after the code for the specific sequela (e.g., chronic kidney disease, neuropathy).
• Ensure documentation clearly links the current condition to a past intentional self-harm event involving peripheral vasodilators.
• Do not use this code for acute poisoning events; use the appropriate acute poisoning code with the 7th character "A" (initial encounter) or "D" (subsequent encounter).
