S72.023N Displaced fracture of epiphysis (separation) (upper) of unspecified femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

• Displaced fracture of epiphysis (separation) (upper) of unspecified femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Summary

This condition involves a displaced fracture or separation of the epiphysis (growth plate) in the upper portion of the femur, classified as an open fracture type IIIA, IIIB, or IIIC, with nonunion. It represents a subsequent encounter for a fracture that has failed to heal properly, requiring ongoing evaluation and management. The open fracture indicates a break in the skin, increasing infection risk, while nonunion signifies incomplete bone healing.

Causes

High-impact trauma, such as falls, sports injuries, or motor vehicle accidents. Direct force to the hip or thigh region that causes the epiphysis to separate, the overlying skin to tear, and disrupts normal bone healing.

Risk Factors

• Adolescence, as growth plates are more vulnerable during development
• Participation in high-impact activities or contact sports
• Underlying bone conditions that weaken structural integrity
• Prior trauma or inadequate initial treatment
• Poor blood supply to the fracture site

Symptoms

• Persistent pain and swelling in the hip or thigh area
• Visible wound or break in the skin at the injury site
• Difficulty bearing weight on the affected leg
• Bruising or tenderness at the injury site
• Limited range of motion in the hip joint
• Possible signs of infection, such as redness or drainage

Diagnosis

Physical examination to assess pain, swelling, and limb alignment. Imaging studies, such as X-rays or CT scans, to visualize the fracture, evaluate nonunion, and assess soft tissue damage. Laboratory tests may be used to check for infection.

Treatment Options

• Surgical intervention to address nonunion and stabilize the fracture
• Wound care to manage the open fracture and prevent infection
• Antibiotics if infection is present
• Physical therapy to restore strength and mobility after healing
• Possible bone grafting to promote union

Prognosis and Follow-Up

Recovery depends on the severity of the fracture, the success of treatment, and the presence of complications. Regular follow-up with imaging is necessary to monitor healing. Long-term outcomes may include persistent pain or functional limitations if nonunion persists.

Complications

• Infection at the fracture site
• Delayed or failed healing (nonunion)
• Malunion or misalignment of the bone
• Chronic pain or arthritis
• Nerve or vascular damage
• Reduced mobility or disability

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Follow prescribed rehabilitation to strengthen the affected area
• Use protective equipment during sports or high-risk activities
• Maintain a healthy diet rich in calcium and vitamin D to support bone health

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible wound, inability to bear weight, signs of infection (e.g., fever, redness, drainage), or worsening symptoms.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC), the presence of nonunion, and the subsequent encounter status. Ensure clinical notes specify the open fracture classification and confirm nonunion to support accurate coding.
