S72.031M Displaced midcervical fracture of right femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Displaced midcervical fracture of right femur, subsequent encounter for open fracture type I or II with nonunion

Summary

A displaced midcervical fracture of the right femur involves a break in the middle portion of the femoral neck (the region connecting the femoral head to the shaft) on the right side, with bone fragments shifted out of alignment. This is a subsequent encounter for an open fracture (type I or II) that has progressed to nonunion, meaning the fracture has not healed properly. The condition requires ongoing evaluation and management to address the fracture and associated soft tissue damage.

Causes

High-impact trauma, such as falls or motor vehicle accidents. Low-impact trauma in individuals with weakened bones (e.g., osteoporosis). Open fractures may result from the bone piercing the skin or from external forces causing both bone and soft tissue injury. Nonunion can develop due to inadequate stabilization, 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)
• Open fracture risk increased by trauma severity and soft tissue involvement
• Factors contributing to nonunion, such as smoking, diabetes, or poor nutrition

Symptoms

• Persistent or recurrent hip or groin pain
• Inability to bear weight on the affected leg
• Swelling, bruising, or tenderness around the hip
• Leg shortening or external rotation of the affected limb
• Visible wound or soft tissue damage (for open fracture)
• Delayed healing or persistent instability

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture and confirm nonunion. Evaluation of soft tissue damage for open fractures. Assessment of healing progress through serial imaging.

Treatment Options

Surgical intervention to stabilize the fracture, such as internal fixation or bone grafting. Antibiotics for open fractures to prevent infection. Pain management and physical therapy to restore function. Monitoring for complications and adjusting treatment as needed.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, soft tissue damage, and response to treatment. Follow-up imaging is typically required to assess healing. Long-term management may involve ongoing rehabilitation and monitoring for arthritis or other complications.

Complications

Nonunion or delayed union of the fracture. Infection, particularly with open fractures. Avascular necrosis (loss of blood supply to the femoral head). Arthritis or joint stiffness. Chronic pain or functional impairment.

Lifestyle & Prevention

Avoid high-risk activities that may lead to trauma. Maintain bone health through adequate calcium and vitamin D intake. Engage in weight-bearing exercises to strengthen bones. Use protective gear during sports or activities with fall risk. Follow post-treatment guidelines to support healing.

When to Seek Professional Help

Persistent or worsening pain, swelling, or bruising. Inability to bear weight on the affected leg. Visible wound or signs of infection (e.g., redness, drainage). Delayed healing or new symptoms indicating complications.

Tips for Medical Coders

Document the fracture type (open I or II), laterality (right femur), and encounter type (subsequent) clearly. Specify nonunion as a key characteristic. Ensure documentation supports the open fracture classification and subsequent encounter status. Note any associated complications or treatment details that may impact coding.
