S82.151M Displaced fracture of right tibial tuberosity, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Displaced fracture of right tibial tuberosity, subsequent encounter for open fracture type I or II with nonunion

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 (type I or II) with nonunion, meaning the fracture has failed to heal properly after an initial injury. Displacement indicates the bone fragments are misaligned, and the open nature of the fracture involves a skin breach, while nonunion signifies incomplete healing over time.

Causes

Traumatic injury is the primary cause, such as direct impact to the knee, falls, or sudden forceful contraction of the quadriceps muscle. Sports-related incidents, motor vehicle accidents, or other high-impact events can lead to this fracture. Open fractures may result from trauma that breaches the skin, and nonunion can occur due to inadequate immobilization, poor blood supply, or infection.

Risk Factors

• Participation in activities with rapid knee extension or jumping (e.g., basketball, soccer)
• Adolescent growth spurts, especially in athletes
• Previous knee injuries or surgeries
• Osteoporosis or bone-weakening conditions
• Inadequate initial fracture management or noncompliance with treatment

Symptoms

• Persistent pain and swelling over the tibial tuberosity
• Inability to fully extend the knee or bear weight
• Visible deformity or abnormal positioning of the knee
• Bruising or discoloration in the affected area
• Open wound or exposed bone (if present)
• Delayed healing or persistent instability

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 for nonunion. Additional tests like CT scans or MRI may be ordered to evaluate soft tissue damage or bone healing. Clinical history of prior fracture and treatment is also considered.

Treatment Options

Treatment focuses on promoting healing and restoring function. Options may include surgical intervention to realign and stabilize the fracture, bone grafting to address nonunion, and immobilization with a cast or brace. Physical therapy is often recommended to regain strength and mobility. Antibiotics may be used if infection is present.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, adherence to treatment, and individual healing capacity. Nonunion may require additional interventions, and recovery can be prolonged. Regular follow-up with imaging and clinical assessments is necessary to monitor healing and adjust treatment as needed.

Complications

• Chronic pain or instability
• Infection (especially with open fractures)
• Nonunion or malunion
• Arthritis or joint damage
• Reduced mobility or function
• Nerve or vascular injury

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Use proper protective gear during sports
• Maintain bone health through nutrition and exercise
• Follow post-injury rehabilitation protocols
• Seek prompt treatment for fractures to reduce nonunion risk

When to Seek Professional Help

Seek immediate medical attention if experiencing severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, increased swelling, redness). Follow up with a healthcare provider if symptoms worsen or do not improve with treatment.

Tips for Medical Coders

Document the fracture type (open I or II), nonunion status, and subsequent encounter details. Include clinical notes on healing progress, treatment interventions, and any complications. Ensure alignment with the specific code description to reflect the open fracture and nonunion characteristics accurately.
