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

Name of the Condition

• Displaced fracture of left tibial tuberosity, subsequent encounter for open fracture type I or II with delayed 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 code specifies a subsequent encounter for an open fracture (type I or II) with delayed healing, indicating the fracture has not progressed as expected during treatment. Open fractures involve the bone piercing the skin, increasing infection risk, while delayed healing refers to a prolonged recovery process.

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, and delayed healing may result from factors like poor blood supply, infection, or inadequate immobilization.

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
• Poor wound care or infection during initial treatment

Symptoms

• Severe pain and swelling over the tibial tuberosity
• Inability to fully extend the knee or bear weight
• Visible deformity or abnormal positioning of the knee
• Bruising or discoloration in the affected area
• Persistent wound drainage or signs of infection (e.g., redness, warmth)
• Prolonged healing time despite treatment

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate displacement. Additional tests like MRI or CT scans may be ordered to assess soft tissue damage or healing progress. Clinical evaluation of the open wound and signs of infection is also critical.

Treatment Options

Treatment focuses on stabilizing the fracture, managing the open wound, and promoting healing. This may include surgical intervention to realign and fix the bone, followed by immobilization with a cast or brace. Antibiotics are often prescribed to prevent or treat infection. Physical therapy may be recommended to restore knee function once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, infection risk, and adherence to treatment. Delayed healing may extend recovery time, requiring closer monitoring. Follow-up appointments are necessary to assess healing through imaging and adjust treatment plans. Physical therapy is typically initiated once the fracture shows signs of progress.

Complications

• Infection at the fracture site or open wound
• Nonunion or malunion of the fracture
• Chronic pain or knee instability
• Limited range of motion
• Nerve or blood vessel damage
• Prolonged disability or inability to return to prior activities

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Follow prescribed immobilization and weight-bearing restrictions
• Maintain good wound care to prevent infection
• Engage in low-impact exercises (e.g., swimming) to preserve mobility
• Ensure adequate nutrition to support bone healing (e.g., calcium, vitamin D)

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Increased pain, swelling, or redness around the fracture site
• Fever or signs of infection (e.g., pus, warmth)
• Sudden inability to move the knee or bear weight
• New or worsening deformity
• Persistent wound drainage or failure to heal

Tips for Medical Coders

This code is used for a subsequent encounter of a displaced left tibial tuberosity fracture that is open (type I or II) with delayed healing. Document the fracture type, laterality, encounter stage, and healing status clearly. Ensure the open fracture classification (type I or II) and evidence of delayed healing (e.g., prolonged healing time, lack of radiographic progress) are well-documented to support coding accuracy.
