S72.045A Nondisplaced fracture of base of neck of left femur, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of base of neck of left femur, initial encounter for closed fracture (S72.045A)

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. The term "nondisplaced" indicates that the bone fragments remain in their normal anatomical position. This type of fracture typically results from trauma or weakened bone structure and requires evaluation to determine the extent of injury and appropriate management.

Causes

High-impact trauma, such as falls or motor vehicle accidents. Low-impact trauma in individuals with weakened bones (e.g., osteoporosis). Repetitive stress or overuse injuries in rare cases.

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)

Symptoms

• Sudden, severe hip or groin pain
• 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

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture and confirm nondisplacement. Documentation of the fracture type and whether the skin is intact (closed fracture) is essential.

Treatment Options

• Non-surgical: Temporary immobilization with a brace or cast, and physical therapy.
• Surgical: Internal fixation (e.g., screws or pins) if the fracture is unstable or at high risk of displacement.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with appropriate treatment. Follow-up imaging may be required to monitor healing. Physical therapy is often recommended to restore strength and mobility. Long-term outcomes depend on fracture severity, patient age, and adherence to rehabilitation.

Complications

• Delayed healing or nonunion
• Avascular necrosis (loss of blood supply to the femoral head)
• Post-traumatic arthritis
• Infection (rare, especially with surgical intervention)
• Deep vein thrombosis (DVT) or pulmonary embolism (PE)

Lifestyle & Prevention

• Maintain bone health through calcium and vitamin D intake.
• Engage in weight-bearing exercises to strengthen bones.
• Use assistive devices (e.g., canes, walkers) to prevent falls, especially in older adults.
• Avoid high-risk activities that increase fracture likelihood.

When to Seek Professional Help

Seek immediate medical attention if you experience severe hip pain, inability to bear weight, or visible deformity after a fall or trauma. Prompt evaluation is critical to prevent complications and ensure proper treatment.

Tips for Medical Coders

Document the fracture location (left femur), type (nondisplaced), and encounter details (initial, closed) to support accurate coding. Ensure clinical documentation specifies the fracture’s anatomical position and whether the skin is intact. Verify that the code aligns with the injury’s characteristics and treatment context.
