S72.135K Nondisplaced apophyseal fracture of left femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Nondisplaced apophyseal fracture of left femur, subsequent encounter for closed fracture with nonunion

Summary

A nondisplaced apophyseal fracture of the left femur is a break in the apophysis, a bony growth area on the femur where tendons or ligaments attach, with the bone fragments remaining in their normal anatomical position. This subsequent encounter code applies to a closed fracture (no open wound) that has developed nonunion, meaning the fracture has failed to heal properly after an initial period of treatment. The condition typically results from trauma or repetitive stress and requires ongoing management to address the nonunion.

Causes

Apophyseal fractures commonly result from direct trauma, such as falls or high-impact injuries, particularly in adolescents during growth spurts. They can also occur from repetitive stress, such as in athletes engaged in activities like running or jumping. Nonunion may develop due to inadequate immobilization, poor blood supply to the fracture site, or underlying factors that impair healing.

Risk Factors

• Adolescence, especially during periods of rapid growth.
• Participation in high-impact sports or activities.
• History of previous injuries to the hip or thigh.
• Underlying bone conditions that weaken the apophysis.
• Factors that impair healing, such as smoking, diabetes, or nutritional deficiencies.

Symptoms

• Persistent localized pain at the hip or thigh, often worsened by movement or pressure.
• Swelling, tenderness, or bruising around the affected area.
• Difficulty bearing weight on the leg.
• Possible limping or altered gait.
• Lack of improvement in symptoms despite prior treatment.

Diagnosis

Physical examination to assess pain, swelling, and tenderness. Imaging studies, including X-rays or MRI, to confirm the fracture and evaluate for nonunion. Additional tests may be performed to assess bone healing and rule out other conditions.

Treatment Options

Treatment focuses on promoting fracture healing and may include immobilization with a cast or brace, physical therapy to restore function, and in some cases, surgical intervention to stabilize the fracture or stimulate healing. Pain management and activity modification are also important components of care.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. Regular follow-up with imaging studies is typically required to monitor healing progress. Most patients can expect improvement with appropriate management, though recovery may be prolonged.

Complications

• Chronic pain or discomfort.
• Persistent difficulty with mobility or weight-bearing.
• Increased risk of future fractures.
• Potential need for surgical intervention if nonunion persists.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Use proper protective equipment during sports or activities.
• Follow post-treatment guidelines to optimize healing.

When to Seek Professional Help

Seek medical attention if symptoms worsen, new symptoms develop, or there is no improvement in pain or mobility despite treatment. Immediate care is needed for severe pain, inability to bear weight, or signs of infection.

Tips for Medical Coders

This code is used for a subsequent encounter for a closed fracture with nonunion. Documentation should specify the fracture type (nondisplaced), location (left femur), encounter type (subsequent), and the presence of nonunion. Ensure all elements of the code are supported by clinical notes to accurately reflect the patient's condition.
