T63.02 Toxic effect of coral snake venom

Name of the Condition

• Toxic effect of coral snake venom
• ICD-10-CM Code: T63.02

Summary

This condition describes the adverse health effects resulting from exposure to coral snake venom, typically through a bite. The code is used when the toxic effects of coral snake venom are the primary focus of the encounter, regardless of the specific circumstances of exposure.

Causes

The condition is caused by the injection of venom from a coral snake into the body, usually via a bite. 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) may assess systemic effects. Imaging is rarely needed unless complications arise.

Treatment Options

• Immediate wound care and administration of antivenom.
• Supportive care for respiratory distress or neurological symptoms.
• Monitoring for systemic effects and complications.

Prognosis and Follow-Up

Prognosis depends on the amount of venom injected, time to treatment, and patient response to antivenom. Follow-up may include monitoring for delayed neurological effects or complications.

Complications

• Respiratory failure due to neurotoxic effects.
• Prolonged muscle weakness or paralysis.
• Secondary infections at the bite site.

Lifestyle & Prevention

• Avoid handling or provoking coral snakes.
• Wear protective clothing and footwear in snake habitats.
• Seek immediate medical attention after a suspected bite.

When to Seek Professional Help

Seek emergency medical care immediately if a coral snake bite is suspected, even if symptoms are mild initially.

Tips for Medical Coders

Use T63.02 when the toxic effects of coral snake venom are the primary focus of the encounter. Document the exposure source (coral snake) and clinical findings to support code assignment.
