T28.0 Burn of mouth and pharynx

Name of the Condition

• Burn of Mouth and Pharynx
• ICD-10-CM Code: T28.0

Summary

Burn of the mouth and pharynx involves thermal, chemical, or electrical injury to the mucosal lining of the oral cavity and pharynx. This condition may result from direct exposure to heat, caustic substances, or electrical current, affecting the upper airway and swallowing structures.

Causes

Burns of the mouth and pharynx typically occur due to ingestion or inhalation of hot liquids, corrosive chemicals, or electrical contact. Thermal burns are common from scalding beverages, while chemical burns may result from accidental or intentional exposure to acidic or alkaline substances.

Risk Factors

• Ingestion of hot foods or liquids without caution.
• Occupational or household exposure to corrosive chemicals.
• Electrical accidents involving oral or pharyngeal contact.
• Intentional self-harm or accidental exposure in children.

Symptoms

• Pain, swelling, or redness in the mouth or throat.
• Difficulty swallowing (dysphagia) or speaking.
• Drooling, hoarseness, or voice changes.
• Possible blisters or ulceration of the mucosa.

Diagnosis

Diagnosis is based on clinical evaluation of symptoms and history of exposure. Direct visualization of the oral cavity and pharynx may reveal burns, while imaging or endoscopy can assess deeper tissue damage if suspected.

Treatment Options

• Immediate removal of the causative agent (e.g., rinsing with water for chemical burns).
• Pain management with topical or systemic analgesics.
• Monitoring for airway compromise, especially with significant swelling.
• Supportive care, including hydration and nutrition, as needed.

Prognosis and Follow-Up

Prognosis depends on the burn's severity and extent. Mild burns often resolve with conservative care, while severe cases may require ongoing monitoring for complications like scarring or functional impairment. Follow-up ensures healing and addresses any persistent symptoms.

Complications

• Airway obstruction due to swelling.
• Infection of damaged mucosal tissue.
• Chronic pain or dysphagia from scarring.
• Systemic toxicity in chemical burn cases.

Lifestyle & Prevention

• Avoid consuming extremely hot foods or liquids.
• Store chemicals safely and out of reach of children.
• Use protective equipment in high-risk occupational settings.
• Supervise young children during mealtime to prevent accidental burns.

When to Seek Professional Help

Seek immediate medical attention if symptoms include severe pain, difficulty breathing, or signs of airway obstruction. Prompt evaluation is critical for burns involving chemicals or electrical exposure.

Tips for Medical Coders

Document the burn's cause (thermal, chemical, electrical) and extent (e.g., localized vs. widespread) to support code assignment. Include details on initial encounter, subsequent care, or sequela if applicable. Ensure clinical correlation with the patient's presentation and treatment.
