S72.045F Nondisplaced fracture of base of neck of left femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Nondisplaced fracture of base of neck of left femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing (S72.045F)

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. The "subsequent encounter" designation signifies follow-up care after the initial injury, and "open fracture type IIIA, IIIB, or IIIC" refers to a fracture where the skin is breached with significant soft tissue damage. "Routine healing" indicates the fracture is progressing normally without complications. This type of injury requires ongoing evaluation to monitor healing and guide management.

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

• 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 healing status. Evaluation of soft tissue damage for open fractures. Assessment of wound healing and infection risk.

Treatment Options

• Pain management with analgesics or anti-inflammatory medications
• Immobilization with a brace, cast, or assistive device to limit weight-bearing
• Surgical intervention if needed to stabilize the fracture or address soft tissue damage
• Physical therapy to restore strength and mobility as healing progresses
• Monitoring for signs of infection or delayed healing

Prognosis and Follow-Up

With routine healing, most nondisplaced fractures of the femoral neck heal without long-term complications. Follow-up care typically includes regular imaging to confirm healing and functional assessments. Recovery time varies but may take several months. Adherence to weight-bearing restrictions and rehabilitation is crucial for optimal outcomes.

Complications

• Delayed or nonunion of the fracture
• Avascular necrosis (loss of blood supply to the femoral head)
• Infection, particularly with open fractures
• Post-traumatic arthritis of the hip joint
• Persistent pain or mobility limitations

Lifestyle & Prevention

• Maintain bone health through adequate calcium and vitamin D intake
• Engage in weight-bearing exercises to strengthen bones
• Use assistive devices (e.g., canes, walkers) to prevent falls in high-risk individuals
• Modify home environments to reduce fall risks (e.g., remove tripping hazards)
• Avoid high-impact activities that increase fracture risk

When to Seek Professional Help

• Severe or worsening pain that is not relieved by prescribed medications
• Signs of infection, such as fever, increased swelling, or pus at the wound site
• New or worsening deformity of the hip or leg
• Inability to bear weight on the affected leg
• Numbness, tingling, or loss of circulation in the affected limb

Tips for Medical Coders

This code (S72.045F) is used for a subsequent encounter for an open fracture of the left femoral neck with routine healing. Documentation should specify the fracture type (IIIA, IIIB, or IIIC) and confirm that healing is progressing without complications. Ensure the encounter is classified as "subsequent" and that the fracture is nondisplaced. Code assignment requires clear documentation of the fracture location, laterality, and healing status.
