S72.324K Nondisplaced transverse fracture of shaft of right femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Nondisplaced Transverse Fracture of Shaft of Right Femur, Subsequent Encounter for Closed Fracture with Nonunion (ICD-10 Code: S72.324K)

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 and is classified as closed (no open wound) with nonunion, indicating the fracture has not healed properly after an initial injury. The subsequent encounter denotes follow-up care for this specific, unhealed fracture.

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. Nonunion may develop due to inadequate immobilization, poor blood supply to the fracture site, infection, or underlying health conditions that impair healing.

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.
• Smoking or poor nutrition, which can hinder bone healing.
• Certain medical conditions (e.g., diabetes, vascular disease) that affect healing.

Symptoms

• Persistent or recurrent pain in the right thigh at the fracture site.
• Swelling, bruising, or tenderness that does not resolve over time.
• Inability to bear weight on the affected leg.
• Possible deformity or instability if the fracture shifts.
• Limited range of motion in the hip or knee.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays, CT scans, or MRI may be used to confirm the fracture, evaluate healing progress, and identify nonunion. Bone scans or ultrasound may also help assess blood flow and tissue viability at the fracture site.

Treatment Options

Treatment focuses on promoting healing and may include surgical intervention (e.g., bone grafting, internal fixation) or non-surgical methods (e.g., prolonged immobilization, electrical stimulation). Pain management, physical therapy, and addressing underlying health issues (e.g., optimizing nutrition, managing diabetes) are also key components of care.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion, overall health, and response to treatment. Follow-up care is essential to monitor healing, adjust treatment plans, and prevent complications. Regular imaging and clinical assessments help track progress and guide further interventions if needed.

Complications

• Chronic pain or disability.
• Infection at the fracture site.
• Nerve or vascular damage.
• Malunion (improper healing) or further displacement.
• Long-term mobility issues or arthritis.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking and limit alcohol, as both impair healing.
• Use protective gear during sports or activities with fall risks.
• Address underlying conditions (e.g., osteoporosis) to reduce fracture risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to move the leg, or if symptoms worsen despite treatment. Contact your provider if you notice signs of infection (e.g., redness, fever) or if the fracture site becomes increasingly unstable.

Tips for Medical Coders

Document the fracture type (nondisplaced transverse), location (shaft of right femur), encounter type (subsequent), and status (closed with nonunion) clearly. Ensure the record specifies nonunion and supports the subsequent encounter context. Include details on treatment approaches and any modifiers relevant to the fracture’s healing status.
