Poisoning by coronary vasodilators, self-harm, init

This code signifies a patient presenting with adverse effects from ingesting or administering coronary vasodilators with the deliberate intent to harm themselves. The poisoning is the result of an overdose or misuse of these medications, leading to a toxic reaction within the body. This specific code indicates the initial treatment for this self-inflicted poisoning event.

Use this code when a patient is admitted to the emergency department or hospital after intentionally taking an excessive amount of medications like nitroglycerin, isosorbide dinitrate, or other drugs primarily used to widen coronary arteries. This applies to the first encounter for treatment of the acute poisoning, such as gastric lavage, administration of antidotes, or supportive care.

• Always assign an additional code for the specific coronary vasodilator involved, if known (e.g., from the T36-T50 range).
• Do not use this code for accidental poisonings or adverse effects from therapeutic use; those require different intent characters.
• Remember to append a subsequent encounter (D) or sequela (S) character for follow-up care related to this poisoning.
