Poisoning by coronary vasodilators, self-harm, subs

This code signifies a patient presenting for follow-up care or complications stemming from a deliberate overdose of medications intended to widen coronary arteries. This could involve drugs like nitrates or calcium channel blockers, taken with the intent to cause self-harm. The patient is no longer in the acute phase of poisoning but is being seen for ongoing management related to the initial event.

Apply this code for subsequent encounters when a patient is being treated for sequelae or ongoing management following an intentional self-poisoning with coronary vasodilators. This includes appointments for monitoring organ damage, psychiatric evaluation, or management of chronic effects resulting from the initial overdose. Do not use for the initial acute poisoning event.

• Always sequence this code after the primary diagnosis for the specific condition being treated during the subsequent encounter.
• Ensure documentation clearly states "intentional self-harm" and that the encounter is not the initial acute treatment.
• Verify the specific substance involved was a coronary vasodilator to differentiate from other drug classes.
