S72.099K Other fracture of head and neck of unspecified femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Other fracture of head and neck of unspecified femur, subsequent encounter for closed fracture with nonunion

Summary

An other fracture of the head and neck of the unspecified femur, subsequent encounter for closed fracture with nonunion, involves a break in the upper portion of the thigh bone affecting the femoral head or neck, where the fracture has failed to heal (nonunion) during a follow-up visit for a closed fracture (no open wound). This condition requires evaluation to assess healing status and guide management, including addressing the nonunion.

Causes

High-impact trauma, such as falls or motor vehicle accidents. Low-impact trauma in individuals with weakened bones (e.g., osteoporosis). Nonunion may result from inadequate immobilization, 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)
• Factors contributing to nonunion, such as smoking, diabetes, or nutritional deficiencies

Symptoms

• Persistent hip or groin pain beyond the typical healing period
• 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 with movement

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to evaluate fracture healing and identify nonunion. Additional tests, such as bone scans or MRI, may be used to assess blood flow or detect infection.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture
• Surgical intervention, such as internal fixation or bone grafting, to promote healing
• Physical therapy to restore strength and mobility
• Pain management with medications or other modalities
• Addressing underlying conditions, such as osteoporosis, to support bone health

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion, overall health, and response to treatment. Regular follow-up with imaging is necessary to monitor healing. Full recovery may take months, and some patients may experience long-term mobility limitations.

Complications

• Chronic pain or arthritis in the hip joint
• Persistent nonunion requiring additional surgery
• Infection (rare, but possible with surgical intervention)
• Nerve or blood vessel damage
• Reduced quality of life due to mobility restrictions

Lifestyle & Prevention

• Maintain a diet rich in calcium and vitamin D to support bone health
• Engage in weight-bearing exercises to strengthen bones
• Avoid high-risk activities that increase fracture risk
• Use assistive devices, such as canes or walkers, to prevent falls
• Quit smoking and limit alcohol consumption, as these can impair healing

When to Seek Professional Help

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

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Include details about the fracture type, healing status, and any interventions performed. Ensure documentation supports the nonunion diagnosis and subsequent encounter context.
