S72.454Q Nondisplaced supracondylar fracture without intracondylar extension of lower end of right femur, subsequent encounter for open fracture type I or II with malunion

Name of the Condition

• Nondisplaced supracondylar fracture without intracondylar extension of lower end of right femur, subsequent encounter for open fracture type I or II with malunion

Summary

This condition involves a fracture at the distal (lower) end of the right femur, specifically in the supracondylar region (above the condyles). The fracture does not extend into the intracondylar area (the space between the condyles), and the bone fragments remain in their normal alignment (nondisplaced). This is a subsequent encounter for an open fracture type I or II, meaning the fracture initially involved a break in the skin with minimal contamination or a larger wound without extensive soft tissue damage. The term "malunion" indicates the fracture has healed in a non-anatomic position, which may affect knee stability and function.

Causes

High-impact trauma, such as falls, motor vehicle accidents, or direct blows to the thigh. Sports injuries or physical altercations. Stress fractures from repetitive overuse or strenuous activity.

Risk Factors

• Advanced age, which may lead to decreased bone density.
• Osteoporosis or other bone-weakening conditions.
• Participation in high-risk activities or contact sports.
• Prior history of femur fractures or bone disorders.

Symptoms

• Severe pain in the knee or thigh region.
• Swelling, bruising, or visible deformity of the affected leg.
• Inability to bear weight or move the leg normally.
• Possible numbness or tingling if nerves are involved.
• Altered limb alignment due to malunion.

Diagnosis

Physical examination to assess pain, swelling, and limb alignment. Imaging studies, such as X-rays or CT scans, to confirm the fracture, evaluate healing, and assess for malunion. Review of prior treatment and fracture history to determine the nature of the subsequent encounter.

Treatment Options

• Immobilization with a cast or brace to support healing.
• Physical therapy to restore strength and mobility.
• Surgical intervention may be considered for significant malunion affecting function.
• Pain management and monitoring for complications.

Prognosis and Follow-Up

Prognosis depends on the degree of malunion and functional impact. Regular follow-up appointments are necessary to monitor healing, assess mobility, and adjust treatment. Long-term outcomes may include persistent pain or reduced range of motion if malunion is severe.

Complications

• Chronic pain or stiffness in the knee.
• Reduced mobility or gait abnormalities.
• Increased risk of future fractures due to altered bone structure.
• Nerve or vascular damage from the initial injury or malunion.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective equipment during sports or high-risk activities.
• Maintain bone health through diet and exercise to reduce fracture risk.
• Follow rehabilitation guidelines to optimize recovery.

When to Seek Professional Help

Seek immediate medical attention for severe pain, swelling, or inability to move the leg. Contact a healthcare provider if symptoms worsen, or if there are signs of infection (e.g., fever, increased redness) at the fracture site.

Tips for Medical Coders

Document the subsequent encounter status, open fracture type (I or II), and presence of malunion clearly. Ensure the record specifies the right femur and confirms the fracture is nondisplaced without intracondylar extension. Code S72.454Q is appropriate for this scenario.
