S72.26XC Nondisplaced subtrochanteric fracture of unspecified femur, initial encounter for open fracture type IIIA, IIIB, or IIIC

Name of the Condition

• Nondisplaced subtrochanteric fracture of unspecified femur, initial encounter for open fracture type IIIA, IIIB, or IIIC

Summary

A nondisplaced subtrochanteric fracture is a break in the femur (thigh bone) just below the lesser trochanter, where the bone remains in its original position without shifting. This condition is classified as an open fracture (type IIIA, IIIB, or IIIC), meaning the skin is breached, exposing the fracture site. The femur is unspecified, and this is the initial encounter for treatment.

Causes

High-impact trauma, such as falls, motor vehicle accidents, or direct force to the hip/thigh. Underlying bone conditions like osteoporosis may increase susceptibility to fracture.

Risk Factors

• Advanced age, particularly over 65
• Osteoporosis or reduced bone density
• History of falls or prior fractures
• Participation in high-impact activities or contact sports

Symptoms

• Severe pain in the hip, groin, or thigh
• Inability to bear weight on the affected leg
• Swelling, bruising, or visible deformity at the fracture site
• Open wound exposing the fracture (for open fracture types)

Diagnosis

Physical examination to evaluate pain, swelling, and limb alignment. Imaging studies, such as X-rays or CT scans, to confirm the fracture location and assess displacement. Assessment for associated injuries or open wound characteristics.

Treatment Options

• Surgical intervention to clean the wound and stabilize the fracture (e.g., internal fixation with plates, screws, or intramedullary nails)
• Antibiotics to prevent infection due to the open wound
• Pain management with medications
• Physical therapy post-stabilization to restore mobility and strength

Prognosis and Follow-Up

Recovery depends on fracture severity, treatment, and patient health. Follow-up includes monitoring for infection, healing progress, and functional restoration. Long-term mobility may be affected, requiring ongoing rehabilitation.

Complications

• Infection at the open fracture site
• Nonunion or delayed healing
• Malunion (improper healing)
• Nerve or vascular damage
• Chronic pain or reduced mobility

Lifestyle & Prevention

• Maintain bone health with calcium and vitamin D
• Engage in weight-bearing exercise to strengthen bones
• Use fall-prevention strategies (e.g., home modifications, assistive devices)
• Avoid high-risk activities without proper protection

When to Seek Professional Help

Seek immediate care for severe hip/thigh pain, inability to bear weight, or visible open wounds. Prompt evaluation is critical for open fractures to reduce infection risk.

Tips for Medical Coders

Document the fracture type (nondisplaced), location (subtrochanteric, unspecified femur), and open fracture classification (IIIA, IIIB, or IIIC). Note the initial encounter and any associated injuries or treatments. Ensure documentation supports the open fracture designation and absence of displacement.
