S72.453H Displaced supracondylar fracture without intracondylar extension of lower end of unspecified femur, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Displaced supracondylar fracture without intracondylar extension of lower end of unspecified femur, subsequent encounter for open fracture type I or II with delayed healing

Summary

This condition involves a displaced fracture at the distal (lower) end of the femur, specifically in the supracondylar region (above the condyles). The fracture does not extend into the intracondylar area (the space between the condyles), distinguishing it from more complex knee joint fractures. Displacement means the bone fragments are out of their normal alignment, potentially affecting knee stability and function. The fracture is open (type I or II), indicating a break in the skin with minimal or moderate soft tissue damage, and this is a subsequent encounter for treatment due to delayed healing.

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.
• Persistent pain or lack of healing progress, indicating delayed healing.

Diagnosis

Physical examination to assess pain, swelling, and deformity. Imaging studies, such as X-rays or CT scans, to confirm the fracture type, displacement, and healing status. Evaluation of the open wound (type I or II) and soft tissue damage. Assessment of healing progress to determine if healing is delayed.

Treatment Options

Immobilization with a cast or brace to stabilize the fracture. Surgical intervention, such as internal fixation, if alignment is poor or healing is not progressing. Wound care for open fractures to prevent infection. Pain management and physical therapy to restore function. Monitoring for signs of delayed healing or complications.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, treatment effectiveness, and individual healing capacity. Delayed healing may require extended follow-up and additional interventions. Regular monitoring with imaging and clinical assessments to track progress. Physical therapy is often necessary to regain strength and mobility.

Complications

Delayed healing or nonunion of the fracture. Infection, particularly with open fractures. Nerve or blood vessel damage. Post-traumatic arthritis or stiffness in the knee joint. Chronic pain or functional limitations.

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 a balanced diet and regular exercise. Follow post-treatment instructions to support healing.

When to Seek Professional Help

Severe or worsening pain, swelling, or deformity. Signs of infection, such as fever, redness, or pus. Numbness, tingling, or loss of circulation in the leg or foot. Inability to bear weight or move the knee. Persistent lack of healing progress.

Tips for Medical Coders

Document the fracture type (open, type I or II), displacement, and lack of intracondylar extension. Note the subsequent encounter and evidence of delayed healing, such as imaging or clinical assessment findings. Ensure documentation supports the open fracture classification and healing status to justify the code.
