T22.24 Burn of second degree of axilla

Name of the Condition

• Burn of second degree of axilla

Summary

This condition involves a second-degree burn affecting the axilla (armpit). Second-degree burns penetrate the epidermis and extend into the dermis, resulting in partial-thickness skin damage. Documentation should specify the anatomical location (axilla) and confirm the burn is classified as second-degree, which typically presents with blistering, pain, and potential tissue injury beneath the epidermis.

Causes

Second-degree burns in the axilla commonly result from exposure to heat (e.g., flames, hot liquids, or prolonged contact with hot surfaces) or chemical agents. The injury involves deeper tissue involvement than first-degree burns, often leading to blistering and increased pain due to damage to both the epidermis and dermis.

Risk Factors

• Proximity to open flames, hot liquids, or corrosive chemicals.
• Lack of protective gear during high-risk activities (e.g., cooking, industrial work).
• Engaging in activities with increased thermal or chemical exposure (e.g., welding, handling chemicals).
• Prolonged sun exposure without protection (e.g., sunburn).

Symptoms

• Pain, redness, and blistering at the injury site.
• Swelling or discoloration of the affected axilla.
• Possible oozing or weeping from blisters.
• Reduced mobility or function of the arm due to axillary involvement.

Diagnosis

Diagnosis is based on clinical evaluation of the burn site, including assessment of skin damage depth, blister presence, and pain levels. Healthcare providers may examine the axilla for signs of partial-thickness injury, such as moist, weeping skin or intact blisters. Documentation should confirm the burn’s degree and anatomical location.

Treatment Options

Treatment focuses on pain management, wound care, and preventing infection. This may include cleaning the burn, applying topical antibiotics, and using dressings to protect the area. For larger or more severe burns, medical intervention (e.g., debridement or specialized dressings) may be necessary. Pain relief and monitoring for complications are also key components of care.

Prognosis and Follow-Up

Most second-degree burns of the axilla heal within 2–3 weeks with proper care, though scarring or changes in skin pigmentation may occur. Follow-up appointments may be scheduled to assess healing progress and address any functional limitations. Severe cases or those with delayed healing may require additional monitoring.

Complications

Potential complications include infection, scarring, or reduced range of motion in the arm. In rare cases, deeper tissue damage or nerve involvement may lead to chronic pain or mobility issues. Prompt treatment and adherence to follow-up care can help minimize these risks.

Lifestyle & Prevention

Prevent burns by avoiding direct contact with heat sources or chemicals. Use protective gear (e.g., gloves, aprons) during high-risk activities, and apply sunscreen to prevent sunburn. Keep flammable materials away from open flames, and ensure proper handling of hot liquids or surfaces.

When to Seek Professional Help

Seek medical attention if the burn is large, shows signs of infection (e.g., increased redness, pus, or fever), or causes severe pain. Additionally, consult a healthcare provider if mobility in the arm is significantly impaired or if blisters are extensive.

Tips for Medical Coders

Document the anatomical location (axilla) and confirm the burn is classified as second-degree. Ensure clinical notes specify the burn’s depth and any associated symptoms (e.g., blistering, pain) to support accurate coding. Avoid using this code for burns of other degrees or locations.
