S72.061N Displaced articular fracture of head of right femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

• Displaced articular fracture of head of right femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC 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 an open fracture (type IIIA, IIIB, or IIIC), meaning the skin is breached, exposing the fracture site, and is documented as a subsequent encounter, indicating ongoing care for a nonunion (failure of the fracture to heal). Prompt evaluation is necessary to assess the extent of displacement, soft tissue damage, and nonunion status to 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). Open fractures may result from direct trauma to the hip, where the bone pierces the skin. Nonunion can occur due to inadequate initial treatment, poor blood supply, infection, or excessive movement at the fracture site.

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 fractures may be more likely in cases of severe trauma or poor soft tissue coverage.
• Factors contributing to nonunion include smoking, diabetes, or inadequate immobilization.

Symptoms

• Sudden, severe 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
• Limited range of motion in the hip joint
• Visible wound or open fracture site (for open fractures)
• Persistent pain or instability indicating nonunion

Diagnosis

Physical examination to assess pain, mobility, limb alignment, and wound status. Imaging studies, including X-rays or CT scans, to visualize the fracture, displacement, and nonunion. MRI may be used to evaluate soft tissue damage or blood supply. Assessment of the open fracture type (IIIA, IIIB, or IIIC) based on wound size, contamination, and soft tissue loss. Evaluation of healing progress to confirm nonunion.

Treatment Options

• Surgical intervention, such as internal fixation or arthroplasty, to stabilize the fracture and address nonunion.
• Debridement and wound care for open fractures to prevent infection.
• Bone grafting or bone stimulation techniques to promote healing in nonunion cases.
• Antibiotics for open fractures to treat or prevent infection.
• Physical therapy to restore mobility and strength after stabilization.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, soft tissue damage, and success of treatment. Open fractures with nonunion may have a longer recovery and higher risk of complications. Regular follow-up with imaging to monitor healing and functional recovery is essential. Long-term management may include activity modifications or assistive devices.

Complications

• Infection, particularly with open fractures.
• Avascular necrosis (loss of blood supply to the femoral head).
• Post-traumatic arthritis due to joint damage.
• Chronic pain or instability from nonunion.
• Nerve or vascular injury from the initial trauma or surgery.
• Deep vein thrombosis or pulmonary embolism.

Lifestyle & Prevention

• Maintain bone health through calcium and vitamin D intake, and weight-bearing exercise.
• Use protective gear during high-risk activities.
• Fall prevention strategies, such as home modifications, for older adults.
• Avoid smoking and manage chronic conditions (e.g., diabetes) to support healing.
• Follow post-treatment guidelines to reduce nonunion risk.

When to Seek Professional Help

Seek immediate care for severe hip pain, inability to bear weight, or visible wounds. Contact a healthcare provider if pain persists, swelling increases, or there are signs of infection (e.g., fever, redness, drainage). Follow up as scheduled for ongoing nonunion management.

Tips for Medical Coders

Document the fracture type (displaced articular), laterality (right femur), encounter type (subsequent), open fracture classification (IIIA, IIIB, or IIIC), and nonunion status. Ensure clinical documentation supports the open fracture type and nonunion to justify the code. Verify that the encounter is subsequent (not initial) and that nonunion is explicitly noted.
