S72.23XK Displaced subtrochanteric fracture of unspecified femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Displaced subtrochanteric fracture of unspecified femur, subsequent encounter for closed fracture with nonunion

Summary

A displaced subtrochanteric fracture of the femur is a break in the thigh bone just below the lesser trochanter, where the bone fragments shift out of their normal alignment. This injury disrupts the structural integrity of the femur and requires ongoing medical attention to address healing complications. The fracture is classified as closed, meaning the skin remains intact, and this is a subsequent encounter for treatment of a nonunion, where the fracture has failed to heal properly after an initial period of time.

Causes

High-impact trauma, such as falls from a height or motor vehicle accidents. Direct force to the hip or thigh region. Underlying bone conditions, including osteoporosis or osteopenia, which reduce bone density and strength. Inadequate initial treatment or poor blood supply to the fracture site may contribute to nonunion.

Risk Factors

• Advanced age, particularly in individuals over 65.
• Chronic conditions affecting bone health, such as osteoporosis or cancer.
• History of prior fractures or bone disorders.
• Participation in high-risk activities or sports with potential for falls or collisions.
• Smoking or other factors that impair bone healing.

Symptoms

• Persistent pain in the hip, groin, or thigh area.
• Inability to bear weight on the affected leg.
• Swelling, bruising, or visible deformity at the fracture site.
• Shortening or rotation of the injured leg.
• Lack of improvement in pain or mobility over time, indicating delayed healing.

Diagnosis

Imaging studies, such as X-rays or CT scans, to confirm the fracture and assess for nonunion. Clinical evaluation of symptoms and healing progress. Comparison with prior imaging to determine if the fracture has failed to unite. Assessment of blood flow and bone health to identify contributing factors.

Treatment Options

Surgical intervention, such as internal fixation with plates, screws, or nails, to stabilize the fracture and promote healing. Bone grafting may be used to stimulate bone growth. Physical therapy to restore strength and mobility. Pain management and monitoring for complications. Adjustments to treatment based on the extent of nonunion and patient health.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion, overall health, and response to treatment. Follow-up imaging and clinical assessments are necessary to monitor healing. Long-term rehabilitation may be required to regain function. Complications, such as infection or persistent pain, can affect recovery.

Complications

Delayed or failed healing (nonunion). Infection, particularly if surgical intervention is needed. Nerve or blood vessel damage. Chronic pain or arthritis in the hip joint. Reduced mobility or disability.

Lifestyle & Prevention

Maintain bone health through a diet rich in calcium and vitamin D. Engage in weight-bearing exercises to strengthen bones. Use fall prevention strategies, such as removing tripping hazards and wearing appropriate footwear. Avoid high-risk activities that increase fracture risk. Manage chronic conditions like osteoporosis with medical guidance.

When to Seek Professional Help

Persistent or worsening pain in the hip or thigh. Inability to bear weight on the affected leg. Signs of infection, such as fever, redness, or drainage. Lack of improvement in symptoms after initial treatment. New or worsening deformity or swelling.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Include details on the fracture's location (subtrochanteric, unspecified femur), displacement, and healing status. Note any surgical interventions or therapies provided. Ensure documentation supports the nonunion diagnosis and closed fracture classification.
