S91.146 Puncture wound with foreign body of unspecified lesser toe(s) without damage to nail

Name of the Condition

• Puncture wound with foreign body of unspecified lesser toe(s) without damage to nail

Summary

This condition describes a puncture wound of one or more lesser toes (toes other than the great toe) where a foreign body is present, and the nail structure remains intact. The injury involves a small, deep break in the skin caused by a pointed object, with the foreign body embedded in the tissue. Management focuses on removing the foreign body, preventing infection, and promoting healing.

Causes

Puncture wounds with foreign bodies of the lesser toes typically result from trauma involving sharp, pointed objects. Common causes include stepping on nails, glass, splinters, or other debris, which can embed in the toe and introduce foreign material.

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 outdoor activities or environments with a high risk of stepping on debris.

Symptoms

• Small, deep puncture in the lesser toe(s).
• Pain, swelling, or tenderness at the injury site.
• Possible bleeding or bruising.
• Sensation of a foreign object embedded in the toe.
• Difficulty wearing shoes or bearing weight on the affected toe.

Diagnosis

Diagnosis is based on a physical examination to assess the wound’s depth, size, and presence of a foreign body. A healthcare professional may also evaluate for signs of infection or tissue damage. Imaging (e.g., X-ray) may be used if a radiopaque foreign body is suspected.

Treatment Options

• Removal of the foreign body, often with local anesthesia.
• Cleaning the wound to reduce infection risk.
• Tetanus prophylaxis if the patient’s immunization is not up to date.
• Antibiotics may be prescribed if infection is present or suspected.
• Wound care instructions, including keeping the area clean and dry.

Prognosis and Follow-Up

Most puncture wounds with foreign bodies heal well with proper care. Follow-up may be recommended to monitor for infection or complications. Healing time depends on the wound’s depth and the patient’s overall health.

Complications

• Infection (e.g., cellulitis or abscess).
• Retained foreign body leading to chronic pain or inflammation.
• Delayed healing due to poor wound care or underlying conditions (e.g., diabetes).

Lifestyle & Prevention

• Wear closed-toe shoes in environments with debris (e.g., construction sites, gardens).
• Inspect feet regularly for injuries, especially after outdoor activities.
• Clean and cover wounds promptly to reduce infection risk.

When to Seek Professional Help

Seek medical attention if:

• The wound is deep, bleeding heavily, or won’t stop bleeding.
• Signs of infection develop (e.g., redness, pus, fever).
• The foreign body is deeply embedded or cannot be easily removed.
• Pain or swelling worsens over time.

Tips for Medical Coders

This code (S91.146) is specific to puncture wounds with foreign bodies in unspecified lesser toes without nail damage. Documentation should clearly indicate the toe(s) involved (unspecified lesser toe(s)), the presence of a foreign body, and the absence of nail damage. Ensure the wound is classified as a puncture (not a laceration or other injury type) and that no additional details (e.g., laterality, specific toe) are documented, as this would require a different code.
