S90.1 Contusion of toe without damage to nail

Name of the Condition

• Contusion of toe without damage to nail

Summary

A contusion of the 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.

Causes

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

Symptoms

• Pain and tenderness around the affected 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.
• Pain relief medications if needed.

Prognosis and Follow-Up

Most contusions heal within 1–2 weeks with proper care. Follow-up may be recommended if symptoms worsen or persist, or if there is concern for underlying injury.

Complications

• Infection if the skin is broken (though this code specifies no nail damage, secondary injury could occur).
• Chronic pain or stiffness if the injury is severe or improperly managed.
• Delayed healing in individuals with poor circulation or other health conditions.

Lifestyle & Prevention

• Wear protective footwear during activities with a high risk of toe injury.
• Ensure shoes fit properly to reduce the risk of stubbing or impact.
• Use caution in environments where heavy objects may fall or where foot trauma is likely.

When to Seek Professional Help

Seek medical attention if there is severe pain, inability to bear weight, signs of infection (e.g., redness, pus), or if the toe appears deformed, as these may indicate a more serious injury.

Tips for Medical Coders

This code (S90.1) is specific to a contusion of the toe without nail damage. Documentation should clearly indicate the absence of nail injury and the anatomical location of the contusion. Ensure the medical record supports the diagnosis and aligns with the code’s criteria to avoid miscoding.
