S72.065K Nondisplaced articular fracture of head of left femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Nondisplaced articular fracture of head of left femur, subsequent encounter for closed fracture with nonunion

Summary

A nondisplaced articular fracture of the head of the left femur involves a break in the femoral head, the rounded upper portion of the thigh bone that forms part of the hip joint, where the fracture fragments remain in their normal alignment. This type of fracture affects the joint surface and is classified as a subsequent encounter for a closed fracture with nonunion, indicating the fracture has not healed properly after prior treatment. Prompt evaluation is essential to assess the nonunion 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). Direct force to the hip region. Inadequate healing following initial fracture management.

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)
• Poor blood supply to the femoral head
• Smoking or other factors that impair bone healing

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 sensation in the hip

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. Assessment of healing progress compared to prior imaging. Evaluation of blood flow to the femoral head if avascular necrosis is suspected.

Treatment Options

• Immobilization with a brace or cast to stabilize the fracture
• Pain management with medications or physical therapy
• Surgical intervention, such as internal fixation or bone grafting, to promote healing
• Joint replacement (e.g., hip arthroplasty) in severe cases
• Rehabilitation to restore mobility and strength

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Regular follow-up with imaging is necessary to monitor healing. Long-term outcomes may include persistent pain or reduced mobility if healing is incomplete. Early intervention improves the likelihood of successful recovery.

Complications

• Avascular necrosis (loss of blood supply to the femoral head)
• Chronic pain or arthritis in the hip joint
• Reduced mobility or disability
• Need for additional surgery
• Infection (rare, but possible with surgical intervention)

Lifestyle & Prevention

• Maintain bone health with calcium and vitamin D intake
• Engage in weight-bearing exercise to strengthen bones
• Avoid high-risk activities that may lead to falls or trauma
• Use assistive devices (e.g., canes, walkers) to prevent falls in older adults
• Quit smoking to improve bone 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). Follow up with your healthcare provider if pain persists or worsens after initial treatment.

Tips for Medical Coders

Document the subsequent encounter for closed fracture with nonunion clearly, including details of the fracture's location (left femur), articular involvement, and nonunion status. Ensure documentation supports the use of this code by confirming the fracture is closed and has not healed after prior treatment. Note any surgical interventions or imaging results that confirm nonunion.
