S72.352K Displaced comminuted fracture of shaft of left femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Displaced comminuted fracture of shaft of left femur, subsequent encounter for closed fracture with nonunion (ICD-10 Code: S72.352K)

Summary

This condition involves a fracture of the left femur (thighbone) where the bone is broken into multiple pieces and the fragments are misaligned. The fracture is localized to the shaft (central portion) of the left femur. It is categorized as a closed fracture (skin remains intact) and is a subsequent encounter for treatment, indicating ongoing care for a fracture that has failed to heal (nonunion).

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 forces or axial loading (e.g., during sports or industrial injuries) can also cause this type of break. Nonunion may occur due to inadequate immobilization, poor blood supply, infection, or excessive movement at the fracture site.

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.
• Smoking or poor nutrition, which can impair healing.

Symptoms

• Persistent pain in the left thigh, often worsening with activity.
• Swelling, bruising, or tenderness at the fracture site.
• Inability to bear weight on the affected leg.
• Visible deformity or shortening of the leg.
• Possible numbness or tingling if nerve involvement occurs.
• Lack of healing progress over time (e.g., no improvement in pain or function).

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to visualize the fracture and assess displacement. Additional scans (e.g., CT or MRI) may be used to evaluate bone healing and rule out nonunion. Blood tests may be performed to check for infection or nutritional deficiencies.

Treatment Options

Treatment focuses on promoting bone healing and may include surgical intervention (e.g., internal fixation, bone grafting) or non-surgical methods (e.g., prolonged immobilization, electrical stimulation). Pain management and physical therapy are often part of the care plan to restore function.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient health, and treatment adherence. Nonunion may require extended follow-up and additional interventions. Regular imaging and clinical assessments are necessary to monitor healing progress.

Complications

• Chronic pain or disability.
• Infection at the fracture site.
• Nerve or vascular damage.
• Malunion (improper healing).
• Long-term mobility issues.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it impairs healing.
• Use protective gear during sports or high-risk activities.
• Follow post-treatment instructions carefully to optimize healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after an injury. Contact your provider if pain persists, worsens, or if you notice signs of infection (e.g., fever, redness, drainage).

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Ensure clinical notes specify the fracture type (displaced, comminuted), location (shaft of left femur), and the presence of nonunion. Include details on treatment provided and any imaging results to support the diagnosis.
