S72.042G Displaced fracture of base of neck of left femur, subsequent encounter for closed fracture with delayed healing

Name of the Condition

• Displaced fracture of base of neck of left femur, subsequent encounter for closed fracture with delayed healing (S72.042G)

Summary

This condition involves a break in the upper portion of the left femur (thigh bone) at the base of the femoral neck, near the hip joint, with the bone fragments shifted out of their normal anatomical position. The term "subsequent encounter" indicates this is a follow-up visit for a previously treated fracture, and "closed fracture with delayed healing" specifies that the skin remains intact (no open wound) and the fracture is not progressing as expected in the healing process. This type of fracture typically affects the structural integrity of the hip joint and requires ongoing evaluation to guide treatment adjustments.

Causes

High-impact trauma, such as falls or motor vehicle accidents, is a common cause. In older adults, particularly those with weakened bone density (e.g., osteoporosis), fractures may occur from minor trauma or low-impact events. Direct force to the hip or thigh region can also result in this injury. Delayed healing may be due to factors like poor blood supply, inadequate immobilization, or underlying health conditions affecting bone repair.

Risk Factors

• Advanced age, especially in individuals over 65
• Osteoporosis or other bone-weakening conditions
• 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 healing (e.g., diabetes, smoking)

Symptoms

• Persistent or worsening hip pain
• Swelling, bruising, or tenderness around the hip
• Inability to bear weight on the affected leg
• Limited range of motion in the hip joint
• Visible deformity or shortening of the leg (if displacement persists)

Diagnosis

Physical examination to assess pain, swelling, and range of motion, followed by imaging studies (e.g., X-rays, CT scans) to evaluate fracture alignment and healing progress. Additional tests (e.g., blood work) may be used to identify underlying conditions affecting healing. Documentation should confirm the fracture type, healing status, and any contributing factors.

Treatment Options

Treatment focuses on promoting healing and may include: immobilization (e.g., braces, casts), physical therapy to restore mobility, pain management, and addressing underlying conditions (e.g., osteoporosis treatment). Surgical intervention (e.g., internal fixation) may be considered if healing does not progress or if displacement recurs.

Prognosis and Follow-Up

Prognosis depends on fracture severity, patient health, and adherence to treatment. Delayed healing may extend recovery time, but most fractures eventually heal with appropriate care. Regular follow-up visits (e.g., imaging, clinical assessments) are essential to monitor progress and adjust treatment as needed.

Complications

• Nonunion (failure to heal)
• Avascular necrosis (bone death due to poor blood supply)
• Chronic pain or arthritis
• Reduced mobility or disability
• Infection (rare, but possible with surgical intervention)

Lifestyle & Prevention

• Maintain bone health through calcium and vitamin D intake
• Engage in weight-bearing exercise to strengthen bones
• Use fall prevention strategies (e.g., home modifications, assistive devices)
• Avoid high-risk activities that increase fracture risk
• Manage underlying conditions (e.g., osteoporosis) with medical guidance

When to Seek Professional Help

Seek care if symptoms worsen (e.g., increased pain, swelling), if weight-bearing becomes impossible, or if new deformities appear. Prompt evaluation is necessary if infection signs (e.g., fever, redness) develop after treatment.

Tips for Medical Coders

Document the fracture type (displaced), location (base of neck of left femur), encounter type (subsequent), and healing status (delayed healing) to support accurate coding. Include details on treatment provided, imaging results, and any factors contributing to delayed healing (e.g., osteoporosis, smoking) to ensure comprehensive coding.
