S72.425D Nondisplaced fracture of lateral condyle of left femur, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Nondisplaced fracture of lateral condyle of left femur, subsequent encounter for closed fracture with routine healing

Summary

A nondisplaced fracture of the lateral condyle of the left femur is a break in the outer bony prominence of the thigh bone near the knee joint, where the bone fragments remain in their normal anatomical position. This subsequent encounter code applies to a closed fracture (skin intact) with routine healing, indicating the fracture is in the recovery phase following initial treatment.

Causes

This fracture typically results from high-impact trauma, such as falls, motor vehicle accidents, or direct blows to the knee. Sports injuries involving sudden twists or impacts can also cause this type of break. The subsequent encounter phase reflects that the initial injury has been addressed, and the focus is on monitoring healing progress.

Risk Factors

• Participation in high-impact or contact sports.
• Osteoporosis or reduced bone density.
• Advanced age, which may weaken bone structure.
• Previous fractures or bone disorders.
• Activities with a high risk of falls or direct trauma to the knee.

Symptoms

• Mild to moderate pain localized around the knee, decreasing over time.
• Residual swelling or bruising in the affected area.
• Gradual improvement in knee mobility and weight-bearing ability.
• Possible stiffness as healing progresses.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and limb alignment. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture and evaluate its extent. Follow-up imaging may be ordered to monitor healing progress and ensure the fracture remains nondisplaced.

Treatment Options

Treatment typically includes immobilization with a brace or cast to support the knee during healing. Physical therapy may be recommended to restore strength and mobility once initial healing is confirmed. Pain management and activity modification are often part of the recovery plan.

Prognosis and Follow-Up

Prognosis is generally favorable for nondisplaced fractures with routine healing, as joint stability and function are often preserved. Follow-up appointments are scheduled to monitor healing progress, assess mobility, and adjust treatment as needed. Most patients regain full function with proper care.

Complications

• Delayed healing or nonunion, though rare with routine healing.
• Residual stiffness or reduced range of motion.
• Post-traumatic arthritis in the knee joint over time.
• Nerve or vascular injury, though uncommon in nondisplaced fractures.

Lifestyle & Prevention

• Engage in low-impact exercises to maintain joint flexibility.
• Use protective gear during high-risk activities.
• Ensure adequate calcium and vitamin D intake to support bone health.
• Avoid activities that place excessive stress on the knee until fully healed.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility declines significantly. Contact a healthcare provider if numbness, tingling, or signs of infection (e.g., redness, fever) occur.

Tips for Medical Coders

This code is used for a subsequent encounter of a closed, nondisplaced fracture of the left femur's lateral condyle with routine healing. Documentation should specify the fracture's status (closed, nondisplaced) and healing progress. Ensure the encounter is subsequent to the initial injury and that healing is proceeding without complications.
