S90.219A Contusion of unspecified great toe with damage to nail, initial encounter

Name of the Condition

• Contusion of unspecified great toe with damage to nail, initial encounter

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. This code is used for the initial encounter of the injury.

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 also typically conducted. Imaging is not usually required unless a fracture or other underlying injury is suspected.

Treatment Options

Treatment may include rest, ice application to reduce swelling, elevation of the foot, and pain management with over-the-counter medications. For significant nail damage, such as a large subungual hematoma, drainage or nail repair may be necessary. Follow-up care ensures proper healing and addresses any complications.

Prognosis and Follow-Up

Most contusions of the great toe with nail damage heal within a few weeks with appropriate care. Follow-up may be recommended to monitor healing, especially if nail bed injury or subungual hematoma is present. Full recovery is expected with no long-term effects in uncomplicated cases.

Complications

Potential complications include infection if the nail bed is injured, persistent pain, or nail deformity. In rare cases, untreated severe nail bed injuries may lead to permanent nail changes.

Lifestyle & Prevention

Wearing properly fitting, closed-toe footwear during activities with a risk of toe injury can help prevent trauma. Being cautious in environments where heavy objects may fall or where stubbing is likely reduces the risk of this injury.

When to Seek Professional Help

Seek medical attention if pain is severe, swelling does not improve, there is signs of infection (e.g., redness, pus), or if walking becomes increasingly difficult. A healthcare provider should evaluate significant nail damage or if a fracture is suspected.

Tips for Medical Coders

Use this code for the initial encounter of a contusion of the unspecified great toe with nail damage. Ensure documentation specifies the injury as initial and notes the absence of more severe trauma (e.g., fracture) to support the code assignment.
