S91.133 Puncture wound without foreign body of unspecified great toe without damage to nail

Name of the Condition

• Puncture wound without foreign body of unspecified great toe without damage to nail

Summary

This condition describes a puncture wound of the great toe where no 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, exposing underlying tissues, and requires evaluation to determine the extent of damage and appropriate management.

Causes

Puncture wounds of the great toe without foreign bodies or nail damage typically result from trauma, such as stepping on sharp objects (e.g., nails, pins, or glass). Common scenarios include minor accidents, contact with tools, or walking barefoot in environments with debris.

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 outdoor activities with a high risk of toe injury.

Symptoms

• Small, deep break in the skin at the great toe.
• Pain, swelling, or tenderness around the wound.
• 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 depth, size, and presence of debris or foreign bodies. A medical history may be taken to evaluate the mechanism of injury and surrounding tissue for signs of infection or additional injuries.

Treatment Options

Treatment focuses on cleaning the wound to prevent infection, which may involve irrigation and antiseptic application. Tetanus status should be assessed and updated if needed. The wound may be left open to heal or closed with sutures, depending on depth and risk of infection. Pain management and wound care instructions are typically provided.

Prognosis and Follow-Up

With proper care, most puncture wounds of the great toe heal without complications. Follow-up may be recommended to monitor for infection or delayed healing, especially if the wound is deep or dirty. Full recovery usually occurs within 1–2 weeks, though swelling or discomfort may persist longer.

Complications

Potential complications include infection (e.g., cellulitis or abscess), delayed healing, or damage to underlying structures (e.g., tendons or nerves). Rarely, tetanus or other systemic infections may occur if the wound is contaminated.

Lifestyle & Prevention

• Wear closed-toe shoes or protective footwear in environments with sharp debris.
• Inspect feet regularly for injuries, especially after outdoor activities.
• Clean wounds promptly and avoid walking barefoot in high-risk areas.

When to Seek Professional Help

Seek medical attention if the wound is deep, heavily contaminated, or shows signs of infection (e.g., increasing pain, redness, pus, or fever). Also, consult a healthcare provider if tetanus vaccination is uncertain or if there is difficulty bearing weight on the toe.

Tips for Medical Coders

Document the location (unspecified great toe) and absence of foreign body or nail damage clearly. Ensure the mechanism of injury and wound characteristics are recorded to support code assignment. Note any associated complications or treatments, as these may impact coding specificity.
