T23.75 Corrosion of third degree of palm

Name of the Condition

• Corrosion of Third Degree of Palm
• ICD-10 Code: T23.75

Summary

This condition involves full-thickness tissue damage to the palm due to corrosive chemical exposure. Third-degree corrosions affect all layers of the skin and may extend to underlying structures like tendons, nerves, or bones. The injury results in tissue necrosis and requires prompt medical evaluation to assess depth and guide treatment.

Causes

Corrosions typically occur from direct contact with caustic substances such as acids, alkalis, or other corrosive chemicals. Common sources include industrial chemicals, household cleaners, or accidental spills. The severity depends on the chemical's concentration, duration of exposure, and the affected area.

Risk Factors

• Occupational exposure to chemicals without protective gear increases risk. Handling hazardous materials, laboratory work, or manufacturing processes involving corrosive agents may elevate likelihood. Accidental exposure during household tasks (e.g., cleaning) or intentional self-harm can also occur.

Symptoms

• Severe pain initially, followed by numbness due to nerve damage. Skin appears white, blackened, or leathery. Tissue may be firm or waxy, with possible eschar formation. Swelling, blistering, or open wounds may develop. Limited mobility or function of the palm is common.

Diagnosis

Diagnosis is based on clinical evaluation of the injury, including assessment of tissue depth, extent of damage, and exposure history. Physical examination may reveal full-thickness skin loss, eschar formation, or involvement of deeper structures. Documentation should specify the affected area (palm) and degree of corrosion.

Treatment Options

Treatment focuses on wound care, pain management, and preventing infection. Debridement of necrotic tissue, topical or systemic antibiotics, and dressings may be used. Surgical intervention, such as skin grafting, may be necessary for extensive damage. Rehabilitation may be required to restore function.

Prognosis and Follow-Up

Prognosis depends on the extent of tissue damage and promptness of treatment. Full recovery is possible with appropriate care, but scarring or functional impairment may occur. Follow-up appointments monitor healing, manage complications, and assess the need for further intervention.

Complications

Potential complications include infection, scarring, contractures, nerve damage, or loss of function. Deep tissue involvement may lead to long-term mobility issues or chronic pain. Systemic toxicity is rare but possible with severe exposure.

Lifestyle & Prevention

Preventive measures include using protective gear (gloves, goggles) when handling corrosive substances. Proper storage and labeling of chemicals, adherence to safety protocols, and immediate washing of exposed skin reduce risk. Avoiding contact with unknown substances is advised.

When to Seek Professional Help

Seek medical attention immediately if corrosive exposure occurs, especially with severe pain, numbness, or visible tissue damage. Prompt evaluation is critical to minimize complications and guide treatment.

Tips for Medical Coders

Document the specific site (palm) and degree of corrosion (third degree) clearly. Ensure clinical notes specify the affected area and depth of tissue involvement. Verify that the code T23.75 is used when the palm is the documented site of third-degree corrosive injury.
