S90.211A Contusion of right great toe with damage to nail, initial encounter

Name of the Condition

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

Summary

A contusion of the right great toe with damage to the nail is a bruise resulting from blunt force trauma that affects both the soft tissues of the toe and the nail structure. This injury typically causes localized pain, swelling, and discoloration, with potential nail bed injury or subungual hematoma (blood under the nail). The condition involves damage to the nail, which may present as discoloration, lifting, or partial/complete nail loss.

Causes

Direct impact or trauma to the right great toe, such as stubbing it against a hard object, dropping a heavy item on it, or injuries during sports or physical activities. The force applied to the toe can damage both the underlying soft tissues and the nail, leading to the combined injury.

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 toes to injury.
• Occupations involving physical labor or environments where foot injuries are more likely.
• Pre-existing conditions like reduced sensation or circulation in the feet, which may increase susceptibility to injury.

Symptoms

• Pain and tenderness around the affected toe.
• Localized swelling and discoloration (bruising) of the skin.
• Nail damage, including discoloration, lifting, or partial/complete nail loss.
• Possible subungual hematoma (blood under the nail).

Diagnosis

Physical examination to assess tenderness, swelling, and discoloration. 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

• Rest and elevation to reduce swelling.
• Ice application to alleviate pain and inflammation.
• Compression with bandages or braces for support.
• Pain relief medications if needed.
• Nail care (e.g., drainage of subungual hematoma) if indicated.

Prognosis and Follow-Up

Most contusions heal within 1–2 weeks with proper care. Follow-up may be recommended if symptoms persist or worsen, or if there is concern for underlying fracture or infection.

Complications

• Infection, particularly if the nail bed is damaged.
• Chronic pain or discomfort.
• Nail deformity or loss.
• Delayed healing due to poor circulation or other underlying conditions.

Lifestyle & Prevention

• Wear protective footwear during high-risk activities.
• Ensure proper fitting shoes to reduce toe exposure.
• Use caution in environments with potential toe trauma (e.g., construction sites).
• Maintain foot health to support healing and prevent future injuries.

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 (removed).

Tips for Medical Coders

Document the specific toe (right great toe), presence of nail damage, and encounter type (initial) to support accurate coding. Ensure clinical documentation aligns with the injury details and mechanism of trauma.
