S72.042E Displaced fracture of base of neck of left femur, subsequent encounter for open fracture type I or II with routine healing

Name of the Condition

• Displaced fracture of base of neck of left femur, subsequent encounter for open fracture type I or II with routine healing (S72.042E)

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 fracture is classified as open (type I or II), meaning there is a wound or break in the skin at the fracture site. This is a subsequent encounter, indicating the patient is receiving follow-up care after the initial injury, and healing is progressing as expected without complications. Routine healing suggests the fracture is responding to treatment without signs of infection or delayed union.

Causes

High-impact trauma, such as falls or motor vehicle accidents, is a common cause. In older adults 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. Open fractures may occur when the trauma causes the bone to pierce the skin or when an external object penetrates the skin and fractures the bone.

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)
• Trauma involving significant force to the hip or thigh

Symptoms

• Persistent but improving hip or groin pain
• Mild swelling or bruising around the hip
• Gradual return of weight-bearing ability on the affected leg
• Reduced range of motion in the hip joint, though improving
• Minimal to no visible deformity as healing progresses

Diagnosis

Diagnosis is based on clinical evaluation and imaging studies, such as X-rays or CT scans, to confirm the fracture type and assess healing progress. The provider will review the patient’s history, including the initial injury and treatment, to determine if healing is proceeding routinely. Physical examination may assess weight-bearing status, range of motion, and signs of infection or complications.

Treatment Options

Treatment typically involves continued monitoring and supportive care, such as pain management and physical therapy to restore function. If the fracture was surgically repaired, follow-up may include checking hardware stability. Non-surgical management may focus on gradual weight-bearing and activity modification. Routine healing indicates no additional interventions are currently needed.

Prognosis and Follow-Up

Prognosis is generally favorable with routine healing, as the fracture is progressing without complications. Follow-up care focuses on ensuring continued healing, restoring mobility, and preventing future fractures. Regular appointments may be scheduled to monitor progress, adjust therapy, and address any new symptoms.

Complications

While routine healing suggests low risk, potential complications include infection (if the open wound was not fully resolved), delayed union, or nonunion of the fracture. Rarely, avascular necrosis of the femoral head or post-traumatic arthritis may occur, though these are less likely with routine healing.

Lifestyle & Prevention

• Engage in weight-bearing exercises to strengthen bones and improve balance
• Ensure adequate calcium and vitamin D intake to support bone health
• Use assistive devices (e.g., canes, walkers) if recommended to reduce fall risk
• Avoid high-impact activities until cleared by a healthcare provider
• Maintain a healthy weight to minimize stress on the hip joint

When to Seek Professional Help

Seek care if symptoms worsen (e.g., increased pain, swelling, or redness), if weight-bearing becomes difficult again, or if signs of infection (e.g., fever, pus, or foul odor from the wound) develop. New or worsening deformity or inability to move the leg should also prompt immediate evaluation.

Tips for Medical Coders

Document the encounter as a subsequent visit for an open fracture type I or II with routine healing. Include details on the fracture’s anatomical location (base of neck of left femur), displacement status, and confirmation of routine healing (e.g., imaging reports or clinical notes indicating expected progress). Ensure the open fracture type (I or II) and subsequent encounter context are clearly documented to support code assignment.
