S72.032M Displaced midcervical fracture of left femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Displaced midcervical fracture of left femur, subsequent encounter for open fracture type I or II with nonunion

Summary

A displaced midcervical fracture of the left femur involves a break in the middle portion of the femoral neck (the region connecting the femoral head to the shaft) on the left side, with the bone fragments shifted out of their normal alignment. This injury is classified as an open fracture type I or II, meaning the fracture penetrates the skin but with minimal soft tissue damage (type I) or moderate soft tissue injury without extensive contamination (type II). The term "nonunion" indicates the fracture has failed to heal properly after an expected period. This is a subsequent encounter, meaning the patient is receiving active treatment for the fracture's nonunion during the healing phase. The condition typically results from trauma and requires ongoing evaluation to assess healing progress, wound status, and guide management.

Causes

High-impact trauma, such as falls or motor vehicle accidents. Low-impact trauma in individuals with weakened bones (e.g., osteoporosis). Repetitive stress or overuse injuries in rare cases.

Risk Factors

• Advanced age, particularly in those over 65
• Osteoporosis or other bone density disorders
• Female gender, due to higher osteoporosis prevalence
• History of prior fractures or bone diseases
• Participation in high-risk activities (e.g., contact sports)
• Poor blood supply to the fracture site
• Inadequate initial treatment or immobilization

Symptoms

• Persistent hip or groin pain at the fracture site
• Inability to bear weight on the affected leg
• Swelling, bruising, or tenderness around the hip
• Leg shortening or external rotation of the affected limb
• Limited range of motion in the hip joint
• Possible visible wound or scar from the open fracture
• Delayed or absent healing signs (e.g., no callus formation on imaging)

Diagnosis

Physical examination to assess pain, mobility, limb alignment, and wound status. Imaging studies, including X-rays or CT scans, to evaluate fracture healing and detect nonunion. Assessment of the open fracture site for signs of infection or soft tissue complications. Review of prior treatment history and imaging to confirm nonunion.

Treatment Options

• Surgical intervention, such as internal fixation or bone grafting, to promote healing.
• Antibiotics or wound care for open fracture management.
• Pain management and physical therapy to restore function.
• Monitoring for complications like infection or further displacement.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion, patient health, and treatment response. Follow-up imaging and clinical evaluations are necessary to assess healing progress. Long-term management may include continued therapy or additional procedures if healing does not occur.

Complications

• Infection at the fracture or wound site
• Persistent nonunion or malunion
• Avascular necrosis of the femoral head
• Chronic pain or reduced mobility
• Need for additional surgeries

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow weight-bearing restrictions as advised.
• Maintain bone health through diet and exercise (if appropriate).
• Use protective measures to prevent falls, especially in older adults.

When to Seek Professional Help

Seek immediate care for worsening pain, signs of infection (e.g., redness, pus), or new swelling. Contact a provider if mobility does not improve or if symptoms persist beyond expected healing timelines.

Tips for Medical Coders

Document the fracture's location (midcervical, left femur), displacement status, open fracture type (I or II), and nonunion. Specify that this is a subsequent encounter for active treatment of the nonunion. Ensure documentation supports the open fracture classification and confirms the fracture has not healed.
