S91.106 Unspecified open wound of unspecified lesser toe(s) without damage to nail

Name of the Condition

• Unspecified open wound of unspecified lesser toe(s) without damage to nail

Summary

This condition describes an open wound of one or more lesser toes (toes other than the great toe) where the nail is not damaged. The wound involves a break in the skin or mucous membrane, exposing underlying tissues, and requires evaluation to determine the extent of injury and appropriate management.

Causes

Open wounds of the lesser toes without nail damage typically result from trauma, such as cuts, abrasions, or blunt force injuries. Common causes include stepping on sharp objects, stubbing the toe, or minor accidents involving the toe.

Risk Factors

• Engaging in activities without protective footwear (e.g., walking barefoot or in open-toed shoes).
• Occupations involving manual labor or exposure to sharp materials.
• Participation in sports or activities with a high risk of toe injury.

Symptoms

• Visible break in the skin at the toe.
• Pain, swelling, or tenderness at the injury site.
• Possible bleeding or bruising.
• Difficulty wearing shoes or bearing weight on the affected toe.

Diagnosis

Diagnosis is based on a physical examination to assess the wound’s size, depth, and contamination. A healthcare professional may evaluate the surrounding tissue for signs of infection or additional injuries, such as fractures.

Treatment Options

• Cleaning the wound to remove debris and reduce infection risk.
• Applying dressings to protect the wound and promote healing.
• Administering tetanus prophylaxis if indicated.
• Prescribing antibiotics for contaminated or infected wounds.
• Monitoring for signs of infection or complications.

Prognosis and Follow-Up

Most uncomplicated open wounds of the lesser toes heal within 1–2 weeks with proper care. Follow-up may be recommended to assess healing progress, especially if the wound is deep, contaminated, or slow to heal. Signs of infection or delayed healing should prompt further evaluation.

Complications

• Infection (e.g., cellulitis, abscess).
• Delayed healing due to poor circulation or underlying conditions.
• Scarring or tissue damage.
• Rarely, deeper tissue injury or nerve damage.

Lifestyle & Prevention

• Wear closed-toe shoes or protective footwear in environments with sharp objects.
• Avoid walking barefoot, especially in hazardous areas.
• Use caution when handling tools or machinery to prevent toe injuries.
• Maintain good foot hygiene to reduce infection risk.

When to Seek Professional Help

Seek medical attention if the wound is deep, heavily contaminated, or shows signs of infection (e.g., increased pain, redness, pus, or fever). Also, consult a healthcare provider if bleeding is severe, the wound does not heal, or there is difficulty bearing weight.

Tips for Medical Coders

This code (S91.106) is specific to an open wound of an unspecified lesser toe(s) without nail damage. Documentation should clearly indicate the toe(s) involved (lesser toe(s), not great toe), the absence of nail damage, and the wound’s characteristics (e.g., depth, contamination). Ensure the mechanism of injury and any associated factors (e.g., infection) are noted to support accurate coding.
