S82.121D Displaced fracture of lateral condyle of right tibia, subsequent encounter for closed fracture with routine healing

Name of the Condition

Displaced fracture of lateral condyle of right tibia, subsequent encounter for closed fracture with routine healing

Summary

This condition involves a displaced fracture of the lateral condyle of the right tibia, a bony prominence on the outer side of the tibia that forms part of the knee joint. The fracture is closed (skin intact) and is being managed during a subsequent encounter, with routine healing progressing as expected.

Causes

This type of fracture typically results from high-impact trauma to the knee, such as a fall, sports injury, or motor vehicle accident. Direct force to the lateral side of the knee can cause the condyle to break and shift out of position.

Risk Factors

• Participation in high-impact sports or activities with a risk of knee injury.
• Osteoporosis or other bone-weakening conditions.
• Previous knee injuries or surgeries.
• Advanced age, which may reduce bone density.

Symptoms

• Pain, swelling, and tenderness around the knee.
• Visible deformity or misalignment of the knee.
• Difficulty bearing weight on the affected leg.
• Bruising or discoloration in the area.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity. Imaging studies, such as X-rays or CT scans, are used to evaluate the fracture type, displacement, and involvement of the knee joint.

Treatment Options

• Immobilization with a cast or brace to allow healing.
• Pain management with medications like NSAIDs.
• Physical therapy to regain strength and mobility.
• Surgical intervention (if needed) to realign and stabilize the fracture with plates, screws, or pins.

Prognosis and Follow-Up

With proper treatment, most fractures of the lateral condyle heal well, and patients can return to normal activities. Follow-up care includes monitoring healing progress through imaging and clinical assessments to ensure alignment and function are restored.

Complications

• Nonunion or delayed healing of the fracture.
• Arthritis in the knee joint due to damage.
• Nerve or blood vessel injury near the fracture site.
• Infection (if the fracture was open, though this code specifies a closed fracture).

Lifestyle & Prevention

• Use protective gear during high-impact activities.
• Maintain bone health through diet and exercise.
• Avoid falls by modifying home environments (e.g., removing tripping hazards).
• Strengthen knee muscles to improve stability.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, redness, drainage) at the injury site.

Tips for Medical Coders

This code (S82.121D) is used for a subsequent encounter for a closed fracture of the lateral condyle of the right tibia with routine healing. Documentation should confirm the fracture is closed, the encounter is subsequent (not initial or acute), and healing is progressing without complications. Ensure the laterality (right tibia) and fracture type (displaced) are clearly documented.
