S90.122D Contusion of left lesser toe(s) without damage to nail, subsequent encounter

Name of the Condition

• Contusion of left lesser toe(s) without damage to nail, subsequent encounter

Summary

A contusion of the left 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). This code is used for subsequent encounters, indicating the patient is receiving follow-up care after the initial injury.

Causes

Direct impact or trauma to the left 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 left 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 (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 involve monitoring for improvement in pain, swelling, or discoloration. If symptoms persist or worsen, further evaluation may be needed to rule out complications.

Complications

• Persistent pain or swelling beyond the expected healing time.
• Development of an infection if the skin is compromised (though rare in uncomplicated contusions).
• Chronic discomfort or limited mobility if the injury is severe or improperly managed.

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 work environments.
• Maintain awareness of surroundings to avoid tripping or stubbing toes.
• Address underlying foot conditions (e.g., bunions) that may increase injury risk.

When to Seek Professional Help

Seek medical attention if:

• Pain is severe or unrelenting.
• Swelling or discoloration worsens or spreads.
• There is difficulty bearing weight on the foot.
• Signs of infection (e.g., redness, warmth, pus) develop.
• The toe appears deformed or mobility is significantly impaired.

Tips for Medical Coders

Use this code for subsequent encounters (D) when the patient is receiving follow-up care for a contusion of the left lesser toe(s) without nail damage. Document the encounter type (subsequent) and confirm no nail injury or fracture is present. Ensure the left toe(s) and absence of nail damage are clearly noted in the medical record.
