S90.129 Contusion of unspecified lesser toe(s) without damage to nail

Name of the Condition

• Contusion of unspecified lesser toe(s) without damage to nail

Summary

A contusion of unspecified lesser toe(s) is a bruise resulting from blunt force trauma that damages underlying soft tissues without breaking the skin or affecting the nail. It typically causes localized pain, swelling, and discoloration in the affected toe(s).

Causes

Direct impact or trauma to the lesser toe(s), such as stubbing it against a hard object or dropping a heavy item on it. Sports injuries or accidents involving the foot may also lead to this condition.

Risk Factors

• Participation in activities with a high risk of toe trauma, such as running or contact sports.
• Wearing open-toed or poorly fitting footwear that exposes the toes to injury.
• Occupations involving physical labor or environments where foot injuries are more likely.

Symptoms

• Pain and tenderness around the affected lesser toe(s).
• Localized swelling and discoloration (bruising) of the skin.
• Possible difficulty walking or applying pressure on the toe(s).

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, and discoloration. A review of the patient’s history to determine the mechanism of injury. Imaging (e.g., X-rays) may be used to rule out fractures or other injuries.

Treatment Options

• Resting the affected toe to avoid further injury.
• Applying ice to reduce pain and swelling.
• Elevating the foot to minimize swelling.
• Over-the-counter pain relievers for discomfort.
• Wearing protective footwear to prevent additional trauma.

Prognosis and Follow-Up

Most contusions resolve within 1–2 weeks with proper care. Follow-up may be recommended if symptoms worsen or persist, to ensure no underlying issues (e.g., fracture) are present.

Complications

• Prolonged pain or swelling if not properly managed.
• Infection if the area is repeatedly irritated.
• Chronic discomfort in rare cases.

Lifestyle & Prevention

• Wear closed-toe, well-fitting shoes during activities with toe injury risk.
• Use protective gear (e.g., toe guards) in sports.
• Maintain awareness of surroundings to avoid accidental impacts.

When to Seek Professional Help

Seek care if pain is severe, swelling worsens, or walking becomes difficult. Also, consult a provider if discoloration spreads or signs of infection (e.g., redness, pus) appear.

Tips for Medical Coders

Document the mechanism of injury, affected toe(s), and absence of nail damage to support code assignment. Ensure clinical notes specify "unspecified" when the exact toe is not identified.
