S82.152E Displaced fracture of left tibial tuberosity, subsequent encounter for open fracture type I or II with routine healing

Name of the Condition

• Displaced fracture of left tibial tuberosity, subsequent encounter for open fracture type I or II with routine healing

Summary

A displaced fracture of the left tibial tuberosity involves a break in the bony prominence on the anterior upper tibia where the patellar tendon attaches. Displacement means the bone fragments are misaligned, which may affect knee function. This specific code refers to a subsequent encounter for an open fracture (type I or II) with routine healing, indicating the fracture has progressed to a healing phase after initial treatment. Open fractures involve the bone piercing the skin, and routine healing suggests no complications like infection or delayed union.

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 occur when the broken bone penetrates the skin, increasing infection risk. The subsequent encounter phase indicates the fracture is now in a healing stage with expected progress.

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
• High-impact trauma, such as falls or direct blows to the knee

Symptoms

• Mild to moderate pain and swelling over the tibial tuberosity (reduced from initial injury)
• Gradual improvement in knee extension and weight-bearing ability
• Minimal visible deformity as healing progresses
• Possible residual bruising or tenderness in the area

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and functional improvement. Imaging studies, such as X-rays, are used to confirm fracture healing and evaluate alignment. Clinical notes should document the open fracture type (I or II) and routine healing status. The subsequent encounter phase is confirmed by evidence of progressing healing without complications.

Treatment Options

Treatment focuses on monitoring healing and restoring function. This may include continued immobilization, physical therapy to improve range of motion, and pain management. Follow-up imaging ensures proper bone union. Surgical intervention is rarely needed at this stage unless complications arise.

Prognosis and Follow-Up

Prognosis is generally favorable with routine healing, though some residual stiffness or weakness may persist. Follow-up appointments monitor healing progress and functional recovery. Most patients regain full knee function with appropriate rehabilitation, but recovery time varies based on injury severity and individual factors.

Complications

• Delayed union or nonunion of the fracture
• Persistent pain or stiffness
• Infection (rare in routine healing phase)
• Malalignment affecting knee mechanics

Lifestyle & Prevention

• Gradual return to activity as healing allows
• Strengthening exercises for the quadriceps and surrounding muscles
• Use of protective gear during high-impact sports
• Maintaining bone health through nutrition and exercise

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new deformity appears. Signs of infection (e.g., redness, pus, fever) or inability to bear weight require immediate evaluation. Persistent functional limitations after healing should be assessed by a healthcare provider.

Tips for Medical Coders

Document the open fracture type (I or II) and confirm routine healing status to support this code. Clinical notes must specify the subsequent encounter phase and absence of complications. Ensure alignment with the fracture’s healing trajectory and any relevant treatment details.
