S72.043A Displaced fracture of base of neck of unspecified femur, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of base of neck of unspecified femur, initial encounter for closed fracture (S72.043A)

Summary

This condition involves a break in the upper portion of the femur (thigh bone) at the base of the femoral neck, near the hip joint. The term "displaced" indicates that the bone fragments have shifted out of their normal anatomical position. This type of fracture typically affects the structural integrity of the hip joint and may require prompt medical evaluation to determine the extent of injury and guide treatment. The "initial encounter for closed fracture" specifies that this is the first visit for a fracture where the skin remains intact.

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.

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)

Symptoms

• Severe pain in the hip or groin area
• Swelling, bruising, or tenderness around the hip
• Inability to bear weight on the affected leg
• Visible deformity or shortening of the leg
• 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 determine displacement. Documentation should confirm the fracture is closed (skin intact) and specify the anatomical location (base of neck of femur) and displacement status.

Treatment Options

• Non-surgical: Temporary immobilization with a brace or cast, and physical therapy.
• Surgical: Internal fixation or hip replacement, depending on fracture severity and patient factors.

Prognosis and Follow-Up

Recovery depends on fracture severity, treatment type, and patient health. Physical therapy is often required to restore mobility. Follow-up imaging may be needed to monitor healing. Long-term outcomes can include reduced mobility or arthritis risk.

Complications

• Nonunion or malunion of the fracture
• Avascular necrosis (bone tissue death due to reduced blood supply)
• Post-traumatic arthritis
• Infection (rare, especially with surgical intervention)
• Blood clots or pulmonary embolism

Lifestyle & Prevention

• Maintain bone health through calcium and vitamin D intake.
• Engage in weight-bearing exercise to strengthen bones.
• Use fall-prevention strategies, such as home modifications and assistive devices for older adults.
• Avoid high-risk activities that increase fracture likelihood.

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, or visible deformity after trauma. Prompt evaluation is critical to prevent complications and optimize treatment.

Tips for Medical Coders

Document the fracture as displaced at the base of the femoral neck, specify the femur as unspecified, and confirm the encounter is initial for a closed fracture. Ensure clinical notes support the displacement and closed nature of the injury to justify code assignment.
