ICD-10: T46.3X3

The ICD-10-CM code T46.3X3 specifically refers to "Poisoning by coronary vasodilators, assault." This code is part of the broader category of T46, which encompasses various types of poisoning, adverse effects, and underdosing related to drugs affecting the cardiovascular system. Below is a detailed clinical description and relevant information regarding this code.

Clinical Description

Definition

The term "coronary vasodilators" refers to a class of medications that are used to widen blood vessels in the heart, thereby improving blood flow and reducing the workload on the heart. These medications are often prescribed for conditions such as angina pectoris, hypertension, and heart failure. However, when ingested inappropriately or in excessive amounts, they can lead to poisoning, which may result in serious health complications.

Mechanism of Action

Coronary vasodilators work by relaxing the smooth muscles of the blood vessels, leading to dilation. This process decreases vascular resistance and lowers blood pressure, which can be beneficial in treating cardiovascular conditions. Common examples of coronary vasodilators include nitrates (like nitroglycerin), calcium channel blockers, and certain antihypertensive agents.

Clinical Presentation

Patients who experience poisoning from coronary vasodilators may present with a variety of symptoms, including:
- Hypotension (low blood pressure)
- Tachycardia (rapid heart rate)
- Dizziness or lightheadedness
- Headaches
- Flushing or warmth of the skin
- Nausea or vomiting

In severe cases, poisoning can lead to syncope (loss of consciousness), shock, or even cardiac arrest, necessitating immediate medical intervention.

Assault Context

The addition of "assault" in the code T46.3X3 indicates that the poisoning was inflicted intentionally by another person. This classification is crucial for legal and medical documentation, as it highlights the need for a thorough investigation into the circumstances surrounding the poisoning.

Implications for Treatment

In cases of poisoning due to assault, the treatment approach may involve:
- Immediate stabilization of the patient, including airway management and intravenous fluids.
- Administration of activated charcoal if the ingestion was recent and the patient is alert.
- Monitoring and supportive care in a hospital setting, particularly for cardiovascular stability.
- Psychological evaluation and support, especially if the patient is a victim of violence.

Coding and Documentation

When documenting cases involving T46.3X3, it is essential to provide comprehensive details regarding:
