S90.212 Contusion of left great toe with damage to nail

Name of the Condition

• Contusion of left great toe with damage to nail

Summary

A contusion of the left great toe with damage to the nail is a bruise resulting from blunt force trauma that affects the soft tissues of the toe and causes injury to the nail structure. This condition typically causes localized pain, swelling, and discoloration, with visible damage to the nail, such as subungual hematoma or nail bed injury. The injury may involve the nail plate, nail bed, or surrounding tissues without breaking the skin.

Causes

Direct impact or trauma to the left great toe, such as stubbing it against a hard object, dropping a heavy item on it, or injuries during physical activities. Sports-related accidents or accidental impacts with objects may also lead to this condition.

Risk Factors

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

Symptoms

• Pain and tenderness around the affected great toe.
• Localized swelling and discoloration (bruising) of the skin.
• Visible damage to the nail, such as subungual hematoma, nail bed injury, or nail plate disruption.
• Possible difficulty walking or applying pressure on the toe.

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, discoloration, and nail integrity. A review of the patient’s history of trauma to the left great toe is typically sufficient for diagnosis. Imaging is rarely needed unless a fracture or severe tissue damage is suspected.

Treatment Options

Treatment focuses on reducing pain and swelling, such as rest, ice application, elevation, and over-the-counter pain relievers. For significant nail damage, a healthcare provider may drain a subungual hematoma or repair the nail bed. Severe cases may require protective dressings or follow-up care.

Prognosis and Follow-Up

Most contusions of the left great toe with nail damage heal within 1–2 weeks with proper care. Follow-up may be recommended if pain persists, swelling worsens, or signs of infection (e.g., redness, pus) develop. Nail regrowth may take several months if the nail bed is injured.

Complications

Potential complications include infection, persistent pain, or nail deformity if the nail bed is severely damaged. Rarely, untreated subungual hematomas can lead to increased pressure and tissue damage.

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 where foot trauma is common.
• Maintain awareness of surroundings to avoid accidental impacts to the left great toe.

When to Seek Professional Help

Seek medical attention if pain is severe, swelling does not improve after 48 hours, there is excessive bleeding, signs of infection (e.g., redness, warmth, pus), or if walking becomes impossible. A healthcare provider should evaluate any suspected fracture or severe nail bed injury.

Tips for Medical Coders

Use code S90.212 for a contusion of the left great toe with damage to the nail. Document the location (left great toe), the presence of nail damage (e.g., subungual hematoma, nail bed injury), and the mechanism of injury (blunt force trauma) to support coding accuracy. Ensure the injury is not associated with an open wound, as this would require a different code.
