S72.323P Displaced transverse fracture of shaft of unspecified femur, subsequent encounter for closed fracture with malunion

Name of the Condition

• Displaced Transverse Fracture of Shaft of Unspecified Femur, Subsequent Encounter for Closed Fracture with Malunion (ICD-10 Code: S72.323P)

Summary

A displaced transverse fracture of the femur shaft involves a horizontal break across the long, central portion of the thigh bone, with the bone fragments misaligned. This fracture affects the diaphysis (main structural part) of the femur and may be associated with soft tissue injury or instability. The "subsequent encounter for closed fracture with malunion" indicates this is a follow-up visit for a fracture that has healed improperly (malunion) without penetrating the skin.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct force to the thigh. Rotational or axial loading injuries (e.g., during sports or industrial accidents) can also cause this type of break. Malunion may occur if the fracture was not properly aligned during initial treatment or if healing was incomplete.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Advanced age, due to decreased bone density.
• Prior history of fractures or bone abnormalities.
• Trauma or accidents involving significant force.

Symptoms

• Persistent pain or discomfort at the fracture site.
• Visible deformity or leg length discrepancy.
• Reduced range of motion in the hip or knee.
• Difficulty bearing weight on the affected leg.
• Possible instability or weakness in the thigh.

Diagnosis

Physical examination to assess alignment, pain, and functional limitations. Imaging tests such as X-rays or CT scans to evaluate the fracture site and confirm malunion. Review of prior treatment records to determine the fracture’s healing progress.

Treatment Options

• Orthopedic evaluation to assess the need for corrective surgery (e.g., osteotomy) to realign the bone.
• Physical therapy to improve strength, mobility, and function.
• Pain management with medications or other modalities.
• Monitoring for complications or further healing issues.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and the patient’s overall health. Follow-up care may include regular imaging to track healing and functional assessments. Long-term outcomes can vary, with some patients experiencing residual pain or mobility limitations.

Complications

• Chronic pain or discomfort.
• Reduced mobility or gait abnormalities.
• Increased risk of future fractures due to altered bone structure.
• Potential need for additional surgical intervention.

Lifestyle & Prevention

• Engage in low-impact exercises to maintain bone health and muscle strength.
• Use protective gear during high-risk activities.
• Ensure adequate calcium and vitamin D intake to support bone density.
• Follow post-treatment guidelines to optimize healing.

When to Seek Professional Help

Seek care if you experience worsening pain, new deformity, or difficulty moving the leg. Prompt evaluation is important if you notice signs of infection (e.g., redness, swelling, fever) or if the fracture site feels unstable.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with malunion. Ensure clinical notes specify the fracture type (displaced transverse), location (shaft of unspecified femur), and the presence of malunion. Verify that the encounter is not an initial treatment or for an open fracture to accurately assign the code.
