ICD-10: T43.213

The ICD-10 code T43.213 specifically refers to "Poisoning by selective serotonin and norepinephrine reuptake inhibitors (SNRIs), assault." This code is part of the broader classification for poisoning and adverse effects related to various substances, particularly focusing on the intentional harm caused by the ingestion of SNRIs.

Clinical Description

Definition of SNRIs

Selective serotonin and norepinephrine reuptake inhibitors are a class of medications primarily used to treat major depressive disorder, anxiety disorders, and certain chronic pain conditions. Common examples include venlafaxine, duloxetine, and desvenlafaxine. These medications work by increasing the levels of serotonin and norepinephrine in the brain, which can help improve mood and alleviate pain.

Poisoning Mechanism

Poisoning by SNRIs can occur through intentional overdose, often in the context of an assault. The effects of such poisoning can be severe and may include:

• Neurological Symptoms: Dizziness, confusion, agitation, seizures, or even coma.
• Cardiovascular Effects: Increased heart rate (tachycardia), hypertension, or arrhythmias.
• Gastrointestinal Distress: Nausea, vomiting, or abdominal pain.
• Serotonin Syndrome: A potentially life-threatening condition characterized by symptoms such as hyperreflexia, tremors, and altered mental status, which can occur when SNRIs are taken in excessive amounts or in combination with other serotonergic drugs.

Clinical Management

Management of SNRI poisoning typically involves:

• Immediate Medical Attention: Patients should be evaluated in an emergency setting.
• Supportive Care: This may include monitoring vital signs, intravenous fluids, and medications to manage symptoms.
• Activated Charcoal: If the patient presents shortly after ingestion, activated charcoal may be administered to limit further absorption of the drug.
• Antidotes: There are no specific antidotes for SNRI poisoning; treatment is primarily symptomatic.

Coding and Documentation

When documenting cases of poisoning by SNRIs, it is crucial to specify the intent (in this case, assault) as it can affect treatment protocols and legal considerations. The T43.213 code is used to indicate that the poisoning was a result of an assault, which may have implications for both clinical management and reporting.
