S72.325P Nondisplaced transverse fracture of shaft of left femur, subsequent encounter for closed fracture with malunion

Name of the Condition

• Nondisplaced Transverse Fracture of Shaft of Left Femur, Subsequent Encounter for Closed Fracture with Malunion (ICD-10 Code: S72.325P)

Summary

A nondisplaced transverse fracture of the shaft of the left femur is a break in the long, central portion of the left 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, meaning the overlying skin is intact. The "subsequent encounter" designation indicates this is a follow-up visit for the fracture, and "malunion" refers to the healing of the fracture in a non-anatomical position, which may affect function or alignment.

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. Malunion may occur if the fracture does not heal properly, often due to inadequate immobilization, poor blood supply, or excessive movement during 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.
• Inadequate immobilization or premature weight-bearing during healing.

Symptoms

• Persistent or recurrent pain in the left thigh, especially with activity.
• Swelling, bruising, or tenderness around the fracture site.
• Visible deformity or limb shortening if malunion is significant.
• Difficulty bearing weight on the affected leg.
• Possible stiffness or reduced range of motion in the hip or knee.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests, such as X-rays or CT scans, are used to confirm the fracture type, assess healing, and identify malunion. The diagnosis is based on clinical findings and radiographic evidence of the fracture and its healing status.

Treatment Options

Treatment focuses on managing symptoms and addressing malunion. Options may include pain management, physical therapy to improve strength and mobility, and orthopedic evaluation for possible intervention (e.g., bracing, surgery) if malunion causes functional impairment. Follow-up imaging is often used to monitor healing.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and the patient’s overall health. Most patients recover with conservative management, but malunion may lead to long-term discomfort or functional limitations. Regular follow-up appointments are necessary to assess healing and adjust treatment as needed.

Complications

• Chronic pain or discomfort.
• Reduced mobility or functional impairment.
• Increased risk of future fractures due to altered bone structure.
• Potential need for surgical correction if malunion is severe.

Lifestyle & Prevention

• Avoid high-impact activities that may stress the healing bone.
• Follow prescribed weight-bearing restrictions and immobilization guidelines.
• Engage in physical therapy to maintain strength and flexibility.
• Maintain bone health through adequate nutrition (e.g., calcium, vitamin D) and exercise.

When to Seek Professional Help

Seek medical attention if you experience increasing pain, swelling, or deformity, or if you notice new numbness or tingling in the leg. Prompt evaluation is important if malunion is suspected or if symptoms worsen.

Tips for Medical Coders

This code is used for a subsequent encounter for a closed fracture with malunion. Document the encounter type (subsequent), fracture status (closed), and the presence of malunion. Ensure clinical documentation supports the diagnosis and the reason for the follow-up visit, including any functional impact of the malunion.
