S82.151J Displaced fracture of right tibial tuberosity, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing

Name of the Condition

• Displaced fracture of right tibial tuberosity, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing

Summary

A displaced fracture of the right tibial tuberosity involves a break in the bony prominence on the anterior upper tibia where the patellar tendon attaches. This specific ICD code refers to a subsequent encounter for an open fracture (types IIIA, IIIB, or IIIC) with delayed healing. Displacement means the bone fragments are misaligned, and the open fracture indicates the bone has pierced the skin or is exposed. Delayed healing suggests the fracture is not progressing as expected during the healing process.

Causes

Traumatic injury is the primary cause, such as direct impact to the knee, falls, or sudden forceful contraction of the quadriceps muscle. High-energy trauma, like motor vehicle accidents or sports-related incidents, can lead to open fractures. Factors contributing to delayed healing may include infection, poor blood supply, or inadequate immobilization.

Risk Factors

• Participation in high-impact activities or contact sports (e.g., basketball, soccer)
• Adolescent growth spurts, which can weaken the growth plate
• Previous knee injuries or surgeries affecting bone or soft tissue
• Open fractures, which increase infection risk and healing challenges
• Conditions that impair circulation or bone health (e.g., diabetes, smoking)

Symptoms

• Persistent pain and swelling over the tibial tuberosity
• Inability to fully extend the knee or bear weight on the affected limb
• Visible deformity or abnormal positioning of the knee
• Open wound or exposed bone fragments (in open fractures)
• Delayed healing signs, such as lack of progress on imaging studies

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity. Imaging studies, such as X-rays, are used to confirm the fracture, evaluate displacement, and assess healing progress. Additional tests like MRI or CT scans may be ordered to evaluate soft tissue damage or infection. Clinical judgment is used to determine if healing is delayed based on time since injury and radiographic findings.

Treatment Options

Treatment focuses on stabilizing the fracture, managing infection (if present), and promoting healing. Options may include surgical intervention to realign and fix the bone, antibiotics for open fractures, and immobilization with a cast or brace. Physical therapy is often recommended to restore function once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, infection control, and adherence to treatment. Delayed healing may require extended follow-up and additional interventions. Regular monitoring with imaging and clinical assessments is necessary to track progress and adjust treatment as needed.

Complications

• Infection (more common with open fractures)
• Nonunion or malunion of the fracture
• Chronic pain or stiffness in the knee
• Tendon or ligament damage affecting knee function
• Nerve or vascular injury in severe cases

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Follow prescribed immobilization and weight-bearing restrictions
• Maintain good nutrition to support bone healing
• Quit smoking, as it impairs circulation and healing
• Use protective gear during sports to reduce injury risk

When to Seek Professional Help

Seek immediate care if there is increased pain, swelling, or drainage from the wound, or if the knee cannot bear weight. Contact a healthcare provider if healing does not progress as expected or if new symptoms (e.g., fever, redness) develop.

Tips for Medical Coders

This code is for a subsequent encounter of a displaced right tibial tuberosity fracture with an open type IIIA, IIIB, or IIIC classification and delayed healing. Document the fracture type, encounter stage, and evidence of delayed healing (e.g., imaging or clinical notes) to support coding. Ensure alignment with the specific open fracture type and healing status described.
