S72.355P Nondisplaced comminuted fracture of shaft of left femur, subsequent encounter for closed fracture with malunion

Name of the Condition

• Nondisplaced comminuted fracture of shaft of left femur, subsequent encounter for closed fracture with malunion (ICD-10 Code: S72.355P)

Summary

This condition involves a fracture of the left femur (thighbone) where the bone is broken into multiple pieces, but the fragments remain in their normal anatomical position (nondisplaced). The fracture is localized to the shaft (central portion) of the left femur. This is a subsequent encounter, meaning the patient is receiving active treatment for the fracture, and it is classified as a closed fracture with malunion, indicating the bone has healed in an abnormal position without proper alignment.

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 can also cause this type of break. Malunion may occur if the fracture fragments heal in a misaligned position, often due to inadequate initial treatment or poor bone healing.

Risk Factors

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

Symptoms

• Persistent pain at the fracture site, even after initial healing.
• Swelling, bruising, or tenderness in the thigh.
• Difficulty bearing weight on the affected leg.
• Possible visible deformity or leg length discrepancy due to malunion.
• Reduced range of motion in the hip or knee.
• Numbness or tingling if nerve involvement occurs.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays or CT scans are used to evaluate the fracture healing and confirm malunion. The diagnosis confirms the fracture is closed (no break in the skin) and that malunion is present, with the encounter classified as subsequent (active treatment ongoing).

Treatment Options

Treatment focuses on managing symptoms and addressing malunion. Options may include physical therapy to improve strength and mobility, pain management with medications, or surgical intervention (e.g., osteotomy) to realign the bone if functional impairment is significant. Bracing or casting may be used to support the leg during healing.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and the patient’s overall health. Most patients recover with conservative management, but malunion may lead to long-term functional limitations. Regular follow-up with imaging and clinical assessments is necessary to monitor healing and adjust treatment as needed.

Complications

• Chronic pain or discomfort.
• Reduced mobility or gait abnormalities.
• Increased risk of future fractures due to altered bone structure.
• Nerve or vascular damage from malaligned bone.
• Post-traumatic arthritis in the hip or knee.

Lifestyle & Prevention

• Engage in weight-bearing exercises to strengthen bones (if appropriate).
• Use protective gear during high-impact activities.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Avoid activities that increase fall risk, especially in older adults.
• Follow post-fracture care instructions to promote proper healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to move the leg, or if you notice worsening deformity. Contact your healthcare provider if symptoms persist or worsen after initial treatment, or if you develop new numbness, tingling, or circulation issues.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with malunion. Ensure clinical notes specify the fracture is nondisplaced, comminuted, and involves the left femur shaft, with confirmation of malunion and active treatment. Code S72.355P is appropriate when the patient is receiving ongoing care for this specific condition.
