S90.219 Contusion of unspecified great toe with damage to nail

Name of the Condition

• Contusion of unspecified great toe with damage to nail

Summary

A contusion of the unspecified 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 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 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, and elevation of the foot. Over-the-counter pain relievers may be recommended. For significant nail damage, a healthcare provider may drain a subungual hematoma or repair the nail bed. Severe cases may require protective dressings or referral to a specialist.

Prognosis and Follow-Up

Most contusions of the great toe with nail damage heal within a few weeks with proper care. Follow-up may be advised if pain persists, infection signs (e.g., redness, pus) develop, or nail regrowth is abnormal. Complications like nail deformity or chronic pain are uncommon but possible.

Complications

Potential complications include infection, especially if the nail bed is injured, or permanent nail deformity. Rarely, untreated severe trauma may lead to chronic pain or difficulty with footwear.

Lifestyle & Prevention

Wearing properly fitting, closed-toe shoes during activities with a risk of toe injury can help prevent trauma. Being cautious in environments with heavy objects or uneven surfaces may reduce the likelihood of stubbing or dropping items on the toe.

When to Seek Professional Help

Seek medical attention if pain is severe, swelling worsens, signs of infection appear, or there is significant nail loss or deformity. A healthcare provider should evaluate if walking becomes difficult or if the toe remains painful after a few days of home care.

Tips for Medical Coders

Document the location (unspecified great toe) and nail damage clearly. Ensure the mechanism of injury (blunt force trauma) and clinical findings (e.g., subungual hematoma, nail bed injury) are recorded to support the code. Verify that no other injuries (e.g., fractures) are present, as these may require additional coding.
