S82.144E Nondisplaced bicondylar fracture of right tibia, subsequent encounter for open fracture type I or II with routine healing

Name of the Condition

• Nondisplaced bicondylar fracture of right tibia, subsequent encounter for open fracture type I or II with routine healing

Summary

A nondisplaced bicondylar fracture of the right 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 fracture is classified as an open fracture type I or II, meaning the skin was breached but the wound was small with minimal contamination. The term "subsequent encounter" indicates this is a follow-up visit for the injury, and "routine healing" confirms the fracture is progressing without complications. The injury affects the weight-bearing surface of the tibia and may involve the knee joint, requiring ongoing monitoring to ensure proper recovery.

Causes

High-energy trauma such as motor vehicle accidents, falls from significant heights, or severe sports injuries that exert force on the knee joint. Penetrating injuries or direct blows to the knee may also result in this fracture. Open fractures occur when the trauma disrupts both the bone and the overlying skin.

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 range of motion. Imaging typically includes X-rays to visualize the fracture and confirm displacement, with additional studies like CT scans if detailed joint assessment is needed. The open fracture classification (type I or II) is determined by the size and contamination of the skin wound.

Treatment Options

Treatment focuses on promoting healing and preventing infection. For open fractures, wound care and antibiotics may be necessary. Nondisplaced fractures often require immobilization with a cast or brace to stabilize the bone. Weight-bearing restrictions and physical therapy are common to support recovery. Surgical intervention is rare for nondisplaced fractures but may be considered if alignment is compromised.

Prognosis and Follow-Up

With routine healing, the prognosis is generally favorable. Most patients recover full function with appropriate treatment and rehabilitation. Follow-up visits monitor healing progress, adjust immobilization, and guide gradual return to activity. Routine healing indicates no signs of infection, delayed union, or nonunion.

Complications

• Infection, particularly with open fractures
• Delayed healing or nonunion
• Arthritis in the knee joint
• Stiffness or reduced range of motion
• Nerve or blood vessel damage (rare)

Lifestyle & Prevention

• Use protective gear during high-impact activities
• Maintain bone health through diet and exercise
• Avoid falls by modifying home environments (e.g., removing tripping hazards)
• Follow post-injury guidelines for weight-bearing and activity

When to Seek Professional Help

Seek care if you experience increased pain, swelling, or redness, signs of infection (e.g., fever, pus), or inability to bear weight. New or worsening numbness, tingling, or changes in skin color also warrant immediate evaluation.

Tips for Medical Coders

Document the fracture type (open I or II), laterality (right tibia), and healing status (routine) to support code assignment. Include details on wound size, contamination, and any interventions (e.g., wound care, antibiotics) to confirm the open fracture classification. Note that "subsequent encounter" applies to follow-up care after the initial treatment phase.
