S72.455D Nondisplaced supracondylar fracture without intracondylar extension of lower end of left femur, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Nondisplaced supracondylar fracture without intracondylar extension of lower end of left femur, subsequent encounter for closed fracture with routine healing

Summary

This condition involves a fracture at the distal (lower) end of the left 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). It is classified as a closed fracture, meaning the skin is intact, and this is a subsequent encounter for treatment with routine healing. This type of fracture typically affects knee stability and function less severely than displaced fractures, depending on the extent of the injury.

Causes

High-impact trauma, such as falls, motor vehicle accidents, or direct blows to the thigh. Sports injuries or physical altercations involving force to the knee or thigh. Stress fractures from repetitive overuse or strenuous activity, though less common for this specific type.

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 area.
• Swelling, bruising, or visible deformity around the knee.
• Inability to bear weight or move the knee joint properly.
• Possible numbness or tingling if nerves are involved.

Diagnosis

Physical examination to assess pain, swelling, and limb alignment. Imaging studies, such as X-rays or CT scans, to confirm the fracture type and healing status. Evaluation of the fracture's alignment and any associated soft tissue damage.

Treatment Options

• Immobilization with a cast or brace to support healing.
• Pain management with medications or physical therapy.
• Monitoring for proper bone healing and alignment.
• Surgical intervention if displacement or instability occurs, though less common for nondisplaced fractures.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative management. Follow-up appointments are necessary to assess healing progress, typically with repeat imaging. Full recovery may take several weeks to months, depending on the patient's age and overall health.

Complications

• Delayed healing or nonunion of the fracture.
• Malalignment or displacement of the bone fragments.
• Nerve or blood vessel damage in the affected area.
• Post-traumatic arthritis or stiffness in the knee joint.

Lifestyle & Prevention

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

When to Seek Professional Help

Seek immediate care if severe pain, swelling, or deformity worsens, or if there is numbness, tingling, or loss of circulation in the leg. Contact a provider if healing does not progress as expected or if new symptoms develop.

Tips for Medical Coders

Document the fracture's location (left femur), type (nondisplaced, supracondylar, no intracondylar extension), encounter type (subsequent), and healing status (routine healing). Include details on whether the fracture is closed and any associated treatments or complications to support accurate coding.
