S72.324M Nondisplaced transverse fracture of shaft of right femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Nondisplaced Transverse Fracture of Shaft of Right Femur, Subsequent Encounter for Open Fracture Type I or II with Nonunion (ICD-10 Code: S72.324M)

Summary

A nondisplaced transverse fracture of the shaft of the right femur is a break in the long, central portion of the right thigh bone, where the fracture line runs horizontally across the bone and the bone fragments remain aligned. This type of fracture involves the diaphysis (main structural part) of the femur. The subsequent encounter indicates this is a follow-up visit for an open fracture type I or II (minimal soft tissue damage) that has not healed properly, resulting in nonunion.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct blows to the thigh. Rotational or axial loading injuries (e.g., during sports or industrial accidents) can also cause this type of break. The open fracture component suggests the trauma was severe enough to penetrate the skin, though the fracture remains nondisplaced. Nonunion may occur due to inadequate stabilization, poor blood supply, or infection.

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.
• Poor blood supply to the fracture site.
• Infection or inadequate initial treatment.

Symptoms

• Persistent pain at the fracture site, even after initial healing.
• Swelling, bruising, or tenderness around the fracture area.
• Inability to bear weight on the affected leg.
• Possible numbness or tingling if nerve involvement occurs.
• Visible signs of nonunion, such as a gap or abnormal movement at the fracture site.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays, CT scans, or MRIs are used to confirm nonunion and evaluate bone healing. Blood tests may be performed to check for infection or nutritional deficiencies that could affect healing.

Treatment Options

Treatment may include surgical intervention, such as bone grafting or internal fixation, to promote healing. Non-surgical options like external fixation or electrical stimulation may be considered. Physical therapy is often recommended to restore strength and mobility. Antibiotics may be prescribed if infection is present.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. Follow-up visits are necessary to monitor healing progress, often with repeated imaging. Long-term recovery may require ongoing rehabilitation to regain full function.

Complications

• Delayed or failed healing (nonunion).
• Infection at the fracture site.
• Nerve or blood vessel damage.
• Chronic pain or disability.
• Malalignment or deformity of the femur.

Lifestyle & Prevention

• Avoid high-impact activities until fully healed.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Use protective equipment during sports or high-risk activities.
• Follow post-treatment instructions carefully to promote healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or signs of infection (e.g., fever, redness, pus). Contact your healthcare provider if symptoms worsen or do not improve with treatment.

Tips for Medical Coders

Document the fracture type (open I or II), the presence of nonunion, and the subsequent encounter status clearly. Ensure clinical notes specify the fracture’s alignment (nondisplaced) and the right femur involvement. Include details on treatment approaches and any complications to support accurate coding.
