T63.023 Toxic effect of coral snake venom, assault

Name of the Condition

• Toxic effect of coral snake venom, assault
• ICD-10-CM Code: T63.023

Summary

This condition describes adverse health effects resulting from exposure to coral snake venom due to an assault, typically through a bite. The code is used when the toxic effects of coral snake venom are the primary focus of the encounter, with the exposure being intentional and non-self-inflicted.

Causes

The condition is caused by the injection of venom from a coral snake into the body, usually via a bite, as a result of an assault. Coral snake venom contains neurotoxins that can affect the nervous system, leading to systemic or localized reactions.

Risk Factors

• Exposure to coral snakes in natural or controlled environments.
• Activities in coral snake habitats (e.g., hiking, farming, or handling snakes).
• Lack of protective measures (e.g., wearing appropriate footwear or clothing).

Symptoms

• Localized pain, swelling, and discoloration at the bite site.
• Systemic effects such as nausea, vomiting, dizziness, or muscle weakness.
• Neurological symptoms (e.g., blurred vision, difficulty breathing, or paralysis) in severe cases.
• Neurotoxic effects (e.g., respiratory distress or muscle paralysis).

Diagnosis

Diagnosis is based on clinical evaluation, including patient history of coral snake exposure and physical examination of bite site characteristics. Laboratory tests (e.g., coagulation studies, renal function tests) may be performed to assess systemic effects.

Treatment Options

• Antivenom administration to neutralize venom effects.
• Supportive care (e.g., airway management, respiratory support).
• Pain management and monitoring for complications.
• Wound care and tetanus prophylaxis as needed.

Prognosis and Follow-Up

Prognosis depends on the amount of venom injected, time to treatment, and patient factors. Early antivenom administration improves outcomes. Follow-up may include monitoring for delayed neurological effects or organ damage.

Complications

• Respiratory failure due to neurotoxic effects.
• Permanent neurological damage.
• Secondary infections at the bite site.
• Organ dysfunction (e.g., renal or cardiac).

Lifestyle & Prevention

• Avoid areas with known coral snake populations.
• Wear protective clothing and footwear in snake habitats.
• Seek immediate medical attention if bitten.

When to Seek Professional Help

Seek emergency care immediately if bitten by a coral snake, especially if symptoms like difficulty breathing, paralysis, or severe pain occur.

Tips for Medical Coders

Use T63.023 when the toxic effect of coral snake venom is documented as resulting from an assault. Ensure the medical record clearly indicates the assault context to support code assignment.
