S72.124P Nondisplaced fracture of lesser trochanter of right femur, subsequent encounter for closed fracture with malunion

Name of the Condition

• Nondisplaced fracture of lesser trochanter of right femur, subsequent encounter for closed fracture with malunion

Summary

This condition involves a break in the lesser trochanter, a bony prominence on the right femur (thigh bone), where the bone fragments remain in their normal anatomical alignment but have healed with malunion (abnormal alignment). The lesser trochanter serves as an attachment point for muscles and ligaments. This is a subsequent encounter, indicating follow-up care after the initial fracture, and the fracture is classified as closed (no open wound).

Causes

Nondisplaced fractures of the lesser trochanter typically result from trauma, such as falls or direct impact injuries. Malunion may occur if the fracture heals in an abnormal position, often due to inadequate immobilization or poor alignment during initial treatment. Underlying bone conditions like osteoporosis can increase susceptibility to fractures and malunion.

Risk Factors

• Advanced age, particularly in postmenopausal women at risk of osteoporosis.
• Conditions that weaken bones, such as osteoporosis, osteopenia, or metastatic bone disease.
• Inadequate initial fracture management or immobilization.
• History of previous fractures or falls.

Symptoms

• Persistent pain in the hip or groin area, often worsened by movement.
• Swelling and bruising around the hip.
• Difficulty in weight-bearing or limping on the affected side.
• Possible functional limitations due to malunion.

Diagnosis

Physical examination includes assessing range of motion, tenderness, and alignment. Imaging studies, such as X-rays or CT scans, confirm the fracture and evaluate for malunion. The diagnosis is based on clinical findings and radiographic evidence of a healed fracture with abnormal alignment.

Treatment Options

Treatment focuses on managing symptoms and addressing functional limitations. Options may include physical therapy to improve strength and mobility, pain management, and in some cases, surgical intervention to correct malunion. The approach depends on the severity of symptoms and functional impact.

Prognosis and Follow-Up

Prognosis varies based on the degree of malunion and functional impairment. Most patients experience improvement with conservative management, but some may have persistent discomfort. Follow-up care involves monitoring for complications and adjusting treatment as needed to optimize recovery.

Complications

• Chronic pain or discomfort due to malunion.
• Reduced mobility or functional limitations.
• Increased risk of future fractures in the affected area.
• Potential need for surgical correction if symptoms are severe.

Lifestyle & Prevention

• Engage in weight-bearing exercises to maintain bone density.
• Use assistive devices (e.g., canes, walkers) to reduce fall risk.
• Ensure proper nutrition, including adequate calcium and vitamin D.
• Follow post-fracture care guidelines to minimize malunion risk.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new swelling, difficulty bearing weight, or signs of infection (e.g., fever, redness). Prompt evaluation is important if functional limitations persist or worsen.

Tips for Medical Coders

Document the presence of malunion and confirm the fracture is closed. Ensure the encounter is coded as subsequent (not initial) and that all relevant clinical details (e.g., imaging findings, treatment provided) support the diagnosis. Verify that the code aligns with the patient's current clinical status and follow-up care.
