S72.355G Nondisplaced comminuted fracture of shaft of left femur, subsequent encounter for closed fracture with delayed healing

Name of the Condition

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

Summary

This condition describes 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 for a closed fracture (no break in the skin) with delayed healing, indicating the fracture has not progressed as expected during the healing process.

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. Delayed healing may occur due to factors like poor blood supply, infection, or inadequate immobilization.

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

Symptoms

• Persistent or worsening pain at the fracture site.
• Swelling, bruising, or tenderness that does not improve over time.
• Inability to bear weight on the affected leg.
• Possible limited range of motion in the hip or knee.
• Delayed or absent signs of healing on imaging.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays or CT scans to evaluate fracture healing and detect signs of delayed union. Additional tests may include blood work to rule out infection or nutritional deficiencies.

Treatment Options

Treatment focuses on promoting healing and may include prolonged immobilization with a cast or brace, physical therapy to maintain mobility, and pain management. In some cases, surgical intervention (e.g., bone grafting or internal fixation) may be necessary to stimulate healing.

Prognosis and Follow-Up

Prognosis depends on the underlying cause of delayed healing and the effectiveness of treatment. Regular follow-up with imaging is typically required to monitor progress. Most fractures eventually heal with appropriate care, though recovery may be prolonged.

Complications

• Nonunion (failure of the bone to heal).
• Infection (if surgical intervention is performed).
• Chronic pain or stiffness.
• Muscle atrophy or weakness from prolonged immobilization.
• Nerve or vascular damage (rare).

Lifestyle & Prevention

• Ensure adequate nutrition, including calcium and vitamin D, to support bone health.
• Avoid smoking and excessive alcohol, which can impair healing.
• Follow prescribed weight-bearing restrictions and rehabilitation guidelines.
• Use protective equipment during high-risk activities to prevent trauma.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity, or if symptoms worsen despite treatment. Contact your healthcare provider if you notice signs of infection (e.g., fever, redness, or drainage) or if healing does not progress as expected.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with delayed healing. Include details about the fracture's location (left femur shaft), comminution, and nondisplacement. Note any interventions or imaging results that confirm delayed healing. Ensure documentation supports the use of the S72.355G code by specifying the fracture type, laterality, and healing status.
