S82.153H Displaced fracture of unspecified tibial tuberosity, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

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

Summary

A displaced fracture of the tibial tuberosity involves a break in the bony prominence on the anterior tibia where the patellar tendon attaches, with misalignment of bone fragments. This code specifies a subsequent encounter for an open fracture (type I or II) that is healing more slowly than expected. Open fractures involve a break in the skin or exposure of the bone, and delayed healing indicates the fracture has not progressed as anticipated during the healing 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 may result from the bone piercing the skin during the initial injury, and delayed healing can occur due to factors like infection, poor blood supply, 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
• Poor wound care or infection following the initial open fracture

Symptoms

• Persistent pain and swelling over the tibial tuberosity
• Inability to fully extend the knee or bear weight
• Visible deformity or abnormal positioning of the knee
• Open wound or scar from the initial fracture, possibly with signs of infection
• Delayed healing, such as lack of progress on follow-up imaging

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity, along with evaluation of the open wound or scar. Imaging studies, such as X-rays, are used to confirm the fracture, evaluate displacement, and assess healing progress. Additional tests like MRI or CT scans may be ordered to evaluate soft tissue damage or infection. Clinical judgment is used to determine if healing is delayed based on the timeline and radiographic findings.

Treatment Options

Treatment focuses on promoting healing and managing the open fracture. This may include wound care to prevent infection, immobilization with a cast or brace, and possibly surgical intervention to realign the bone or address soft tissue issues. Antibiotics may be prescribed if infection is present. Physical therapy is often recommended to restore function once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of treatment, and any complications. Delayed healing may extend recovery time, but most fractures eventually heal with appropriate care. Follow-up appointments are necessary to monitor healing through imaging and clinical assessment. Adjustments to treatment may be made based on progress.

Complications

• Infection at the site of the open fracture
• Nonunion or malunion of the fracture
• Chronic pain or stiffness in the knee
• Nerve or blood vessel damage
• Reduced range of motion or functional impairment

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Follow prescribed immobilization and weight-bearing instructions
• Maintain good nutrition to support bone healing
• Practice proper wound care if an open fracture is present
• Use protective gear during sports to reduce injury risk

When to Seek Professional Help

Seek medical attention if there is increased pain, swelling, or redness, especially if accompanied by fever (signs of infection). Contact a provider if the knee cannot bear weight, there is new deformity, or healing does not progress as expected. Immediate care is needed for signs of nerve or vascular compromise, such as numbness, coldness, or discoloration.

Tips for Medical Coders

This code is used for a subsequent encounter of a displaced tibial tuberosity fracture that is open (type I or II) with delayed healing. Document the fracture type, encounter stage, and evidence of delayed healing (e.g., clinical assessment, imaging) to support coding. Ensure the open fracture classification (type I or II) and subsequent encounter status are clearly documented.
