S72.063K Displaced articular fracture of head of unspecified femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

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

Summary

A displaced articular fracture of the head of the unspecified femur involves a break in the femoral head, the rounded upper portion of the thigh bone that forms part of the hip joint, with the fracture fragments shifted out of their normal alignment. This injury disrupts joint mechanics and may result from trauma or weakened bone structure. The fracture is classified as closed, meaning the skin remains intact, and nonunion indicates the fracture has not healed properly after an expected time frame. This subsequent encounter code applies when the patient is receiving active treatment for the nonunion.

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.

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)

Symptoms

• Persistent 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

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture and assess for nonunion. Evaluation of healing progress over time to confirm the fracture has not united.

Treatment Options

• Immobilization with casting or bracing to stabilize the fracture
• Surgical intervention, such as internal fixation or bone grafting, to promote healing
• Physical therapy to restore mobility and strength
• Pain management with medications or other modalities
• Monitoring for signs of healing or complications

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient age, and overall health. Nonunion may require extended treatment or additional procedures. Regular follow-up with imaging is necessary to assess healing. Long-term outcomes may include persistent pain, reduced mobility, or the need for joint replacement.

Complications

• Chronic pain
• Avascular necrosis (loss of blood supply to the femoral head)
• Post-traumatic arthritis
• Infection (if surgical intervention is required)
• Persistent nonunion or malunion

Lifestyle & Prevention

• Maintain bone health through adequate calcium and vitamin D intake
• Engage in weight-bearing exercises to strengthen bones
• Use fall prevention strategies, such as removing tripping hazards at home
• Avoid high-risk activities that increase fracture risk
• Follow post-treatment guidelines to support healing

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, or signs of infection (e.g., fever, redness, drainage). Contact a healthcare provider if pain persists or worsens despite treatment, or if mobility does not improve.

Tips for Medical Coders

This code is used for a subsequent encounter for a closed fracture with nonunion of the femoral head. Document the encounter type (subsequent) and confirm the fracture is closed and nonunion is present. Ensure clinical documentation supports the nonunion diagnosis and that the encounter is for active treatment of the condition.
