S82.142H Displaced bicondylar fracture of left tibia, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Displaced bicondylar fracture of left tibia, subsequent encounter for open fracture type I or II with delayed healing

Summary

A displaced bicondylar fracture of the left tibia involves a break in both the lateral and medial condyles of the tibia (shinbone) near the knee joint, with the bone fragments misaligned. This fracture is classified as an open fracture type I or II, meaning the skin is breached but the wound is limited in size or contamination. The injury affects the weight-bearing surface of the tibia and may involve damage to surrounding soft tissues. The "subsequent encounter" and "delayed healing" modifiers indicate this is a follow-up visit for a fracture that is not progressing as expected in the healing process.

Causes

High-energy trauma such as motor vehicle accidents, falls from significant heights, or severe sports injuries that exert force on the knee joint are common causes. Penetrating injuries or direct blows to the knee can also result in this type of 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
• Poor blood supply to the fracture site
• Infection or other complications from the initial injury

Symptoms

• Persistent 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
• Visible deformity or instability of the knee in severe cases
• Open wound or laceration at the fracture site (for open fractures)
• Delayed or incomplete healing observed over time

Diagnosis

Diagnosis is confirmed through a combination of physical examination and imaging studies. A physical exam assesses pain, swelling, and range of motion. Imaging typically includes X-rays to evaluate fracture alignment and healing progress, with CT scans or MRIs used to assess soft tissue damage or complications. Laboratory tests may be ordered to check for infection or nutritional deficiencies affecting healing.

Treatment Options

Treatment focuses on promoting healing and may include immobilization with a cast or brace, surgical intervention to realign and stabilize the fracture (e.g., internal fixation), or bone grafting to stimulate healing. Antibiotics are used for open fractures to prevent infection. Physical therapy is often recommended to restore strength and mobility once healing allows.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, adherence to treatment, and any underlying health conditions. Delayed healing may require extended follow-up, including regular imaging to monitor progress. Most patients eventually regain function, but some may experience long-term stiffness, arthritis, or reduced mobility. Follow-up visits are essential to assess healing and adjust treatment as needed.

Complications

• Nonunion or malunion of the fracture
• Infection at the fracture site or surgical site
• Post-traumatic arthritis of the knee
• Nerve or blood vessel damage
• Chronic pain or stiffness
• Need for additional surgeries

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Maintain a healthy diet rich in calcium and vitamin D to support bone health
• Use protective gear during sports or activities with fall risks
• Manage underlying conditions like osteoporosis to reduce fracture risk
• Follow rehabilitation plans to optimize recovery

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after an injury, or if an open wound is present. Contact your healthcare provider if you notice signs of infection (e.g., redness, pus, fever) or if pain or swelling worsens during recovery.

Tips for Medical Coders

This code is used for a subsequent encounter for an open fracture type I or II of the left tibia with delayed healing. Document the fracture type (open I/II), laterality (left), and the reason for delayed healing (e.g., poor blood supply, infection, or noncompliance with treatment). Ensure the encounter is classified as "subsequent" and that healing status is clearly noted to support the code.
