S90.02 Contusion of left ankle

Name of the Condition

• Contusion of left ankle

Summary

A contusion of the left ankle is a bruise resulting from blunt force trauma that damages underlying soft tissues without breaking the skin. It involves localized injury to the left ankle region, typically causing pain, swelling, and discoloration.

Causes

Direct impact or trauma to the left ankle, such as a fall or collision. Sudden twisting or bending of the left ankle during physical activity. Blunt force from objects striking the left ankle area.

Risk Factors

• Participation in sports or activities with high ankle injury risk (e.g., running, jumping).
• Wearing improper footwear or inadequate support.
• Pre-existing ankle instability or previous injuries.

Symptoms

• Pain and tenderness around the left ankle.
• Swelling and bruising (discoloration) of the skin.
• Limited range of motion or difficulty bearing weight.

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.

Prognosis and Follow-Up

Most contusions heal within 1–2 weeks with proper care. Follow-up may be recommended if symptoms persist or worsen to ensure no underlying issues are present.

Complications

• Prolonged pain or swelling beyond the typical healing period.
• Development of chronic instability or recurrent injuries.
• Infection if the skin is compromised (rare for contusions).

Lifestyle & Prevention

• Wear supportive footwear appropriate for activities.
• Use protective gear during high-risk sports.
• Maintain ankle strength and flexibility through exercises.
• Avoid uneven surfaces that increase fall risk.

When to Seek Professional Help

Seek care if pain is severe, swelling does not improve, or weight-bearing is impossible. Also, consult a provider if discoloration worsens or signs of infection (e.g., redness, pus) appear.

Tips for Medical Coders

Document the specific location (left ankle) and mechanism of injury clearly. Ensure the diagnosis aligns with clinical findings and patient history. Use this code for initial encounters of uncomplicated contusions; specify laterality and encounter type as applicable.
