S90.212A Contusion of left great toe with damage to nail, initial encounter

Name of the Condition

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

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

• Rest and elevation of the affected toe to reduce swelling.
• Ice application to minimize pain and inflammation.
• Pain relief with over-the-counter analgesics if needed.
• Nail care, such as draining a subungual hematoma or protecting the nail bed, if indicated.
• Follow-up if symptoms worsen or do not improve within a few days.

Prognosis and Follow-Up

Most contusions of the great toe with nail damage heal within 1–2 weeks with proper care. Follow-up may be recommended if there is severe nail injury, persistent pain, or signs of infection. Full recovery is expected with no long-term complications in uncomplicated cases.

Complications

• Infection if the nail bed is exposed or damaged.
• Persistent pain or discomfort if the injury is severe.
• Nail deformity or loss if the nail matrix is injured.
• Delayed healing in individuals with poor circulation or other underlying conditions.

Lifestyle & Prevention

• Wear protective footwear during activities with a risk of toe injury.
• Ensure shoes fit properly to avoid pressure on the great toe.
• Use caution in environments where foot trauma is likely, such as construction sites or sports fields.
• Maintain good foot hygiene to reduce infection risk if the nail is damaged.

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 nail is completely avulsed or severely damaged. Prompt evaluation is important if symptoms worsen or do not improve after initial care.

Tips for Medical Coders

Document the specific location (left great toe), the presence of nail damage, and the encounter type (initial) to support accurate coding. Ensure clinical notes reflect the mechanism of injury, examination findings, and treatment provided to justify the code assignment.
