S72.354P Nondisplaced comminuted fracture of shaft of right femur, subsequent encounter for closed fracture with malunion

Name of the Condition

• Nondisplaced comminuted fracture of shaft of right femur, subsequent encounter for closed fracture with malunion (ICD-10 Code: S72.354P)

Summary

This condition describes a fracture of the right femur (thighbone) where the bone is broken into multiple pieces (comminuted) but remains in its normal anatomical position (nondisplaced). The fracture is localized to the shaft (central portion) of the bone. This is a subsequent encounter for a closed fracture (no break in the skin) that has healed with malunion, meaning the bone fragments have united in a non-anatomical position.

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 initial fracture was not properly aligned or stabilized during 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 localized pain in the thigh, even after initial healing.
• Swelling, bruising, or tenderness at the fracture site.
• Altered gait or difficulty bearing weight on the affected leg.
• Possible visible deformity or shortening of the leg due to malunion.
• Reduced range of motion in the hip or knee.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays or CT scans are used to evaluate the fracture site, confirm malunion, and assess bone healing. Comparison with prior imaging may help determine the extent of malalignment.

Treatment Options

Treatment depends on the severity of malunion and functional impact. Options may include physical therapy to improve strength and mobility, pain management, or surgical intervention (e.g., osteotomy) to realign the bone. Bracing or orthotics may be used to support the leg during recovery.

Prognosis and Follow-Up

Prognosis varies based on the degree of malunion and patient factors. Most patients experience improved function with appropriate treatment, though some residual pain or mobility limitations may persist. Regular follow-up with imaging and clinical assessments is important to monitor healing and functional outcomes.

Complications

• Chronic pain or discomfort.
• Reduced mobility or gait abnormalities.
• Increased risk of future fractures due to altered bone structure.
• Potential need for additional surgery if malunion causes significant functional impairment.

Lifestyle & Prevention

• Engage in weight-bearing exercises to maintain bone density (if appropriate).
• Use protective equipment during high-impact activities.
• Ensure proper nutrition, including adequate calcium and vitamin D.
• Follow post-fracture care instructions to optimize healing and reduce malunion risk.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new swelling, or difficulty bearing weight on the affected leg. Prompt evaluation is important if you notice changes in leg alignment or function.

Tips for Medical Coders

This code is used for a subsequent encounter for a closed fracture with malunion. Document the encounter type (subsequent), fracture status (closed), and presence of malunion. Ensure clinical documentation supports the malunion diagnosis and that the encounter is not for initial treatment or active fracture care.
