S72.134K Nondisplaced apophyseal fracture of right femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

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

Summary

A nondisplaced apophyseal fracture of the right femur is a break in the apophysis, a growth plate 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 skin breakage) that has developed nonunion, meaning the fracture has failed to heal properly after an initial period of treatment.

Causes

Apophyseal fractures commonly result from direct trauma, such as falls or high-impact injuries, particularly in adolescents during growth spurts. Nonunion may occur due to inadequate immobilization, poor blood supply to the fracture site, infection, or excessive movement during 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 unchanged or worsened over time.
• Swelling, tenderness, or bruising around the affected area.
• Difficulty bearing weight on the leg.
• Possible limping or altered gait.
• No signs of new displacement or open wound.

Diagnosis

Physical examination to assess pain, swelling, and tenderness. Imaging studies, including X-rays or MRI, to confirm the fracture and evaluate nonunion (lack of bone healing over time). Assessment of prior treatment history and healing progress.

Treatment Options

• Immobilization with casting or bracing to stabilize the fracture.
• Surgical intervention, such as bone grafting or internal fixation, if nonunion persists.
• Physical therapy to restore strength and mobility.
• Pain management with medications or other modalities.
• Monitoring for signs of healing or complications.

Prognosis and Follow-Up

Prognosis depends on the severity of nonunion and response to treatment. Follow-up imaging and clinical evaluations are typically required to assess healing progress. Long-term outcomes may include persistent pain or functional limitations if nonunion is not resolved.

Complications

• Chronic pain or discomfort.
• Limited mobility or functional impairment.
• Increased risk of future fractures.
• Potential need for additional surgical interventions.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow prescribed immobilization and rehabilitation protocols.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Use protective equipment during sports or activities to reduce injury risk.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or new symptoms (such as fever or open wounds) develop. Prompt evaluation is important if nonunion is suspected or if healing does not progress as expected.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Include details on prior treatment, imaging findings confirming nonunion, and any interventions performed. Ensure the code aligns with the clinical status of the fracture and the encounter type.
