S72.059K Unspecified fracture of head of unspecified femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

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

Summary

An unspecified fracture of the head of the femur, with a subsequent encounter for a closed fracture that has failed to heal (nonunion), involves a break in the upper portion of the thigh bone affecting the femoral head (the ball-shaped top of the femur). This type of fracture occurs near the hip joint and is classified as closed (no skin penetration) but has not united during the healing process. Prompt evaluation is essential to assess the nonunion, determine the cause of delayed healing, 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). Factors contributing to nonunion may include inadequate immobilization, poor blood supply to the fracture site, infection, or underlying medical conditions that impair healing.

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)
• Conditions that impair bone healing (e.g., diabetes, smoking, or nutritional deficiencies)
• Inadequate initial fracture management or immobilization

Symptoms

• Persistent hip or groin pain, often worsening with activity
• 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 site and confirm nonunion (e.g., persistent fracture line with no bridging bone). Additional tests, such as bone scans or MRI, may be used to evaluate blood supply or detect infection.

Treatment Options

• Immobilization with braces or casts to stabilize the fracture
• Surgical intervention, such as internal fixation (plates, screws) or bone grafting, to promote healing
• Physical therapy to restore strength and mobility
• Pain management with medications or other modalities
• Addressing underlying conditions (e.g., osteoporosis treatment) to support healing

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion, overall health, and response to treatment. Follow-up imaging and clinical assessments are typically required to monitor healing progress. Long-term management may involve ongoing physical therapy and regular monitoring to prevent complications.

Complications

• Chronic pain or disability
• Avascular necrosis (loss of blood supply to the femoral head)
• Post-traumatic arthritis of the hip joint
• Infection (if surgical intervention is performed)
• Need for additional surgeries or prolonged rehabilitation

Lifestyle & Prevention

• Maintain bone health through adequate calcium and vitamin D intake
• Engage in weight-bearing exercises to strengthen bones
• Avoid high-risk activities that increase fracture risk
• Use assistive devices (e.g., canes, walkers) to prevent falls, especially in older adults
• Quit smoking and limit alcohol consumption, as these can impair bone healing

When to Seek Professional Help

Seek immediate medical attention if you experience sudden, severe hip pain, inability to bear weight, or visible deformity. Contact your healthcare provider if pain persists, worsens, or if you notice signs of infection (e.g., fever, redness, or drainage) after treatment.

Tips for Medical Coders

This code (S72.059K) is used for a subsequent encounter for a closed fracture of the femoral head with nonunion. Documentation should specify the fracture type (closed), the encounter type (subsequent), and the presence of nonunion. Ensure the record includes details about the fracture's location (unspecified femur head) and the reason for the encounter (nonunion).
