S90.112A Contusion of left great toe without damage to nail, initial encounter

Name of the Condition

• Contusion of left great toe without damage to nail, initial encounter

Summary

A contusion of the left great toe 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. This code is used for the initial encounter, meaning it is the first time a healthcare professional is addressing this injury.

Causes

Direct impact or trauma to the left great toe, 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 toe to injury.
• Occupations involving physical labor or environments where foot injuries are more likely.

Symptoms

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

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 (e.g., acetaminophen or ibuprofen) for discomfort.
• Wearing protective footwear to prevent additional trauma.

Prognosis and Follow-Up

Most contusions heal within 1–2 weeks with proper care. Follow-up may be recommended if symptoms worsen or persist beyond this timeframe to rule out complications. Gradual return to normal activities is advised as pain and swelling subside.

Complications

• Persistent pain or swelling beyond the expected healing period.
• Development of infection if the skin is compromised (though uncommon in uncomplicated contusions).
• Underlying fractures or soft tissue damage if trauma was severe.

Lifestyle & Prevention

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

When to Seek Professional Help

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

Tips for Medical Coders

Use this code for the initial encounter of a left great toe contusion without nail damage. Document the mechanism of injury, absence of nail involvement, and that this is the first encounter. Ensure laterality (left) and encounter type (initial) are clearly recorded.
