S72.061K Displaced articular fracture of head of right femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Displaced articular fracture of head of right femur, subsequent encounter for closed fracture with nonunion

Summary

A displaced articular fracture of the head of the right femur involves a break in the femoral head (the ball portion of the hip joint) with displacement of the bone fragments. This injury affects the articular surface, which is critical for smooth joint movement. The fracture is classified as closed (no open wound) and is documented as a subsequent encounter, indicating ongoing care for a fracture that has failed to heal (nonunion). Prompt evaluation is necessary to assess the extent of displacement and guide appropriate management.

Causes

High-impact trauma, such as falls or motor vehicle accidents. Low-impact trauma in individuals with weakened bones (e.g., osteoporosis). Direct force to the hip region. Nonunion may result from inadequate immobilization, poor blood supply, or infection.

Risk Factors

• Advanced age, particularly in those over 65
• Osteoporosis or other bone density disorders
• Female gender, due to higher osteoporosis prevalence
• History of prior fractures or bone diseases
• Participation in high-risk activities (e.g., contact sports)
• Factors contributing to nonunion, such as smoking, diabetes, or inadequate initial treatment.

Symptoms

• Persistent hip or groin pain, often worsening with movement
• Inability to bear weight on the affected leg
• Swelling, bruising, or tenderness around the hip
• Leg shortening or external rotation of the affected limb
• Limited range of motion in the hip joint
• Possible clicking or grinding sensations during movement.

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture and displacement. MRI may be used to evaluate soft tissue damage or blood supply. Bone scans or CT angiography can help assess for nonunion or avascular necrosis.

Treatment Options

• Non-surgical management: Pain control, activity modification, and physical therapy to improve mobility.
• Surgical intervention: Internal fixation to stabilize the fracture, bone grafting to promote healing, or hip replacement (arthroplasty) for severe cases.
• Monitoring for complications, such as avascular necrosis or arthritis.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient age, and response to treatment. Nonunion may require additional interventions. Regular follow-up with imaging to assess healing progress is essential. Long-term outcomes may include chronic pain, reduced mobility, or the need for joint replacement.

Complications

• Nonunion or delayed union of the fracture
• Avascular necrosis (loss of blood supply to the femoral head)
• Post-traumatic arthritis of the hip joint
• Infection (if surgical intervention is required)
• Chronic pain or disability
• Leg length discrepancy.

Lifestyle & Prevention

• Maintain bone health through calcium and vitamin D intake, and weight-bearing exercise.
• Avoid high-risk activities that may lead to falls or trauma.
• Use assistive devices (e.g., canes, walkers) to reduce fall risk, especially in older adults.
• Quit smoking, as it impairs bone healing.
• Follow post-treatment guidelines to optimize recovery and prevent complications.

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, or visible deformity. Contact a healthcare provider if pain persists, worsens, or is accompanied by swelling, fever, or signs of infection. Follow up with an orthopedic specialist for ongoing management of nonunion or complications.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Ensure the code S72.061K is used when the fracture is closed, displaced, and has failed to heal after prior treatment. Include details about the fracture type, laterality (right femur), and the presence of nonunion to support accurate coding. Verify that the encounter is not an initial or acute phase of care.
