S82.151A Displaced fracture of right tibial tuberosity, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of right tibial tuberosity, initial encounter for closed fracture
• Medical term: Displaced fracture of tibial tuberosity

Summary

A displaced fracture of the right tibial tuberosity involves a break in the bony prominence on the upper tibia where the patellar tendon attaches. This specific ICD code refers to an initial encounter for a closed fracture, meaning the bone fragments do not pierce the skin. The displacement indicates the bone fragments are misaligned, which may affect knee function.

Causes

Direct trauma to the knee, such as a fall or sports injury, is the primary cause. Sudden or excessive stress on the knee, particularly in young athletes, can also lead to this fracture. High-impact incidents, including motor vehicle accidents or direct blows to the knee, may result in this type of injury.

Risk Factors

• Engaging in contact sports (e.g., football, basketball) or activities with rapid knee movements.
• Participation in activities with a high risk of falls or twists to the knee.
• Adolescent growth spurts, especially in active children, which can weaken the growth plate.

Symptoms

• Severe pain and swelling around the knee, localized to the tibial tuberosity.
• Inability to fully extend the leg or bear weight on the affected limb.
• Visible deformity or abnormal positioning of the knee due to bone displacement.
• Bruising or discoloration in the knee area.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity. Imaging tests, such as X-rays, are used to confirm the fracture and evaluate displacement. The closed nature of the fracture is determined by the absence of an open wound or exposed bone.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture and allow healing.
• Pain management through medications or ice therapy to reduce swelling.
• Surgical intervention may be required if the fracture is severely displaced or unstable.
• Physical therapy to restore knee function and strength after healing.

Prognosis and Follow-Up

Most displaced fractures of the tibial tuberosity heal with proper immobilization and rest. Follow-up appointments are necessary to monitor healing and adjust treatment. Long-term prognosis is generally good, but some patients may experience residual knee stiffness or weakness.

Complications

• Nonunion or delayed healing of the fracture.
• Malunion, where the bone heals in a misaligned position.
• Chronic pain or instability in the knee.
• Infection (rare, but possible if surgical intervention is required).

Lifestyle & Prevention

• Use protective gear during high-impact sports to reduce injury risk.
• Strengthen knee muscles through targeted exercises to improve stability.
• Avoid sudden, forceful movements that strain the knee, especially during growth spurts.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.

When to Seek Professional Help

Seek immediate medical attention if you experience severe knee pain, inability to bear weight, or visible deformity after an injury. Prompt evaluation is necessary to assess the fracture and prevent complications.

Tips for Medical Coders

This code (S82.151A) is specific to a displaced fracture of the right tibial tuberosity with an initial encounter for a closed fracture. Documentation should clearly indicate the side (right), displacement, and that the fracture is closed. Ensure the encounter is classified as "initial" and that no open wound or exposure is documented.
