S72.332F Displaced oblique fracture of shaft of left femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Displaced Oblique Fracture of Shaft of Left Femur, Subsequent Encounter for Open Fracture Type IIIA, IIIB, or IIIC with Routine Healing

Summary

A displaced oblique fracture of the shaft of the left femur is a break in the long, central portion of the thigh bone where the fracture line runs at an angle, and the bone fragments are misaligned. This condition is classified as a subsequent encounter for an open fracture (type IIIA, IIIB, or IIIC) with routine healing, indicating the fracture is being managed during a follow-up visit after initial treatment, and the healing process is progressing normally. The fracture involves the diaphysis (main structural part) of the femur and may have been associated with significant soft tissue injury during the initial trauma.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct force to the thigh. Rotational or axial loading injuries, common in sports or industrial settings, can also cause this type of break. Open fractures occur when the trauma is severe enough to penetrate the skin, exposing the fracture site, and the subsequent encounter reflects ongoing care for the healing process.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Advanced age, due to decreased bone density.
• Prior history of fractures or bone abnormalities.
• Trauma or accidents involving significant force.

Symptoms

• Sharp, localized pain in the thigh (may be reduced during healing).
• Swelling, bruising, or tenderness around the fracture site (diminishing over time).
• Possible residual instability or deformity if alignment was not fully restored.
• Limited range of motion in the hip or knee.
• Skin changes at the prior open fracture site (e.g., scarring).

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to visualize the fracture site and confirm healing progress. Clinical evaluation of the prior open fracture site for signs of infection or delayed union. Review of prior treatment records to determine the fracture type and healing status.

Treatment Options

• Monitoring of healing through regular imaging and clinical assessments.
• Pain management with analgesics or anti-inflammatory medications.
• Physical therapy to restore strength, mobility, and function.
• Follow-up care to address any residual symptoms or complications.
• Surgical intervention (if needed) for malunion or nonunion, though routine healing reduces this likelihood.

Prognosis and Follow-Up

Most displaced oblique fractures of the femur shaft with routine healing progress well, with full recovery expected over several months. Follow-up care focuses on ensuring proper alignment, monitoring for complications, and restoring function. Regular appointments with an orthopedic specialist are typical to assess healing and adjust treatment as needed.

Complications

• Delayed union or nonunion of the fracture.
• Residual pain or functional impairment.
• Infection at the prior open fracture site.
• Malalignment or deformity if initial reduction was incomplete.
• Post-traumatic arthritis in the hip or knee.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Engage in low-impact exercises (e.g., swimming, cycling) to maintain mobility.
• Ensure adequate calcium and vitamin D intake to support bone health.
• Use protective equipment during sports or high-risk activities.
• Follow weight-bearing restrictions as advised by a provider.

When to Seek Professional Help

• Increasing pain, swelling, or redness at the fracture site.
• Fever or signs of infection (e.g., pus, warmth).
• Sudden loss of function or inability to bear weight.
• New deformity or instability in the leg.
• Persistent numbness or tingling in the leg or foot.

Tips for Medical Coders

This code (S72.332F) is used for a subsequent encounter for an open fracture of the left femur shaft (type IIIA, IIIB, or IIIC) with routine healing. Documentation should specify the fracture type, limb (left), and that healing is progressing without complications. Ensure the encounter is classified as "subsequent" and that the fracture is confirmed to be healing routinely, with no evidence of delayed union, nonunion, or infection.
