S82.146D Nondisplaced bicondylar fracture of unspecified tibia, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Nondisplaced bicondylar fracture of unspecified tibia, subsequent encounter for closed fracture with routine healing

Summary

A nondisplaced bicondylar fracture of the tibia involves a break in both the lateral and medial condyles of the tibia (shinbone) near the knee joint, where the bone fragments remain in their normal alignment. This type of fracture affects the weight-bearing surface of the tibia and is classified as closed, meaning the skin is intact. The subsequent encounter indicates this is a follow-up visit for an injury that is healing as expected without complications.

Causes

High-energy trauma such as motor vehicle accidents, falls from significant heights, or severe sports injuries that exert force on the knee joint. Direct blows to the knee or penetrating injuries may also result in this fracture.

Risk Factors

• Participation in high-impact sports or activities with a risk of falls
• Osteoporosis or other conditions that weaken bone density
• Advanced age, which may reduce bone strength
• Previous knee injuries or surgeries that compromise joint stability

Symptoms

• Intense pain localized to the knee, particularly with weight-bearing
• Swelling, bruising, or tenderness around the knee joint
• Inability to bear weight on the affected leg
• Limited range of motion or stiffness
• Possible audible "pop" or crack at the time of injury

Diagnosis

Diagnosis is confirmed through a combination of physical examination and imaging studies. A physical exam assesses pain, swelling, and deformity. Imaging, typically X-rays, evaluates the fracture pattern and confirms the absence of displacement. Follow-up imaging may be used to monitor healing progress during subsequent encounters.

Treatment Options

Treatment focuses on immobilization with a cast or brace to support the fracture during healing. Weight-bearing restrictions are often recommended initially, with gradual resumption as healing progresses. Physical therapy may be prescribed to restore strength and range of motion once the fracture shows signs of routine healing.

Prognosis and Follow-Up

With proper immobilization and adherence to weight-bearing guidelines, nondisplaced fractures typically heal well without long-term complications. Follow-up visits are scheduled to monitor healing and adjust treatment plans as needed. Most patients regain full function, though recovery time varies based on individual factors.

Complications

While routine healing is expected, potential complications include delayed union, nonunion, or malunion of the fracture. Infection risk is low for closed fractures but may increase with open injuries. Long-term joint stiffness or arthritis may occur in some cases.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Strengthening exercises for the knee and surrounding muscles may help prevent future injuries. Wearing protective gear during sports and using proper fall techniques can reduce fracture risk.

When to Seek Professional Help

Seek immediate care if pain worsens, swelling increases, or new symptoms such as numbness, tingling, or discoloration develop. Follow-up with a provider if the fracture does not show signs of healing or if mobility does not improve as expected.

Tips for Medical Coders

This code is used for a subsequent encounter of a closed, nondisplaced bicondylar tibial fracture with routine healing. Documentation should specify the fracture type, encounter stage, and healing status. Ensure the record confirms the fracture is closed and healing without complications to support accurate coding.
