S72.454A Nondisplaced supracondylar fracture without intracondylar extension of lower end of right femur, initial encounter for closed fracture

Name of the Condition

• Nondisplaced supracondylar fracture without intracondylar extension of lower end of right femur, initial encounter for closed fracture

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 an initial encounter for a closed fracture, meaning the skin is intact and there is no open wound. The injury may affect knee stability and function depending on the severity of the trauma.

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.

Diagnosis

Physical examination to assess pain, swelling, and limb alignment. Imaging studies, such as X-rays or CT scans, to confirm the fracture and rule out other injuries. Documentation of the fracture as nondisplaced and without intracondylar extension is critical for accurate coding.

Treatment Options

Immobilization with a cast or brace to allow healing. Pain management with medications or ice. Physical therapy to restore mobility and strength once healing progresses. Surgical intervention is typically not required for nondisplaced fractures but may be considered if alignment changes.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment. Follow-up appointments to monitor healing through imaging and assess functional recovery. Return to normal activities is gradual, with physical therapy often recommended to prevent stiffness.

Complications

Delayed healing or nonunion if the fracture does not stabilize properly. Post-traumatic arthritis in the knee joint over time. Nerve or vascular damage, though rare with nondisplaced fractures. Infection risk if the fracture were open (not applicable here).

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. Practice fall prevention strategies, especially for older adults.

When to Seek Professional Help

Severe pain that worsens or does not improve with rest. Signs of infection, such as fever, redness, or drainage (unlikely with a closed fracture but requires evaluation). Sudden increase in swelling or inability to move the leg. Numbness, tingling, or changes in skin color, which may indicate nerve or vascular involvement.

Tips for Medical Coders

Use code S72.454A for the initial encounter of a closed, nondisplaced supracondylar fracture without intracondylar extension of the right femur. Document the fracture type (nondisplaced, no intracondylar extension), laterality (right), and encounter type (initial, closed) to ensure accurate coding. Differentiate from displaced fractures or those with intracondylar involvement, as these require separate codes.
