S82.154M Nondisplaced fracture of right tibial tuberosity, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Nondisplaced fracture of right tibial tuberosity, subsequent encounter for open fracture type I or II with nonunion

Summary

A nondisplaced fracture of the right tibial tuberosity involves a break in the bony prominence on the anterior upper tibia where the patellar tendon attaches, with no misalignment of bone fragments. This is a subsequent encounter for an open fracture type I or II, meaning the skin over the fracture site was compromised but the wound was limited, and the fracture has failed to heal (nonunion). The tibial tuberosity is critical for knee extension, and even nondisplaced fractures can impact function, especially when healing is delayed.

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 injury breaches the skin, exposing the fracture site. Nonunion may result from inadequate stabilization, poor blood supply, infection, or excessive movement during healing.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer)
• Adolescent growth spurts, especially in athletes
• Previous knee injuries or surgeries
• Activities involving sudden stops or jumps
• Poor nutrition or smoking, which can impair bone healing
• Inadequate initial treatment or immobilization

Symptoms

• Persistent localized pain and swelling over the tibial tuberosity
• Difficulty extending the knee or bearing weight
• Visible wound or laceration at the fracture site (for open fractures)
• Bruising or tenderness on palpation
• Possible clicking or grinding sensation with knee movement
• Delayed healing or lack of progress in recovery

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and functional limitations. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate displacement. CT or MRI may be ordered to assess bone healing and rule out nonunion. Clinical history, including the timing of the injury and previous treatments, is critical to determine the encounter type and fracture classification.

Treatment Options

Treatment focuses on promoting bone healing and restoring function. Options may include surgical fixation to stabilize the fracture, bone grafting to stimulate healing, or continued immobilization. Physical therapy is often recommended to restore strength and range of motion. Antibiotics may be necessary for open fractures to prevent infection. Pain management and activity modification are also part of the plan.

Prognosis and Follow-Up

Prognosis depends on the success of healing and the extent of functional recovery. Nonunion may require additional interventions, such as surgery, to achieve union. Regular follow-up with imaging is necessary to monitor healing progress. Most patients can return to normal activities, but recovery may be prolonged, especially with complications like nonunion or infection.

Complications

• Nonunion or delayed healing
• Infection (more common with open fractures)
• Chronic pain or instability
• Limited range of motion
• Muscle weakness or atrophy
• Need for additional surgeries

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Use proper protective gear during sports
• Maintain a healthy diet rich in calcium and vitamin D to support bone health
• Quit smoking, as it impairs healing
• Follow rehabilitation guidelines to restore strength and mobility
• Attend all follow-up appointments to monitor healing

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to bear weight. Contact your healthcare provider if symptoms worsen, or if you notice signs of infection (e.g., redness, warmth, fever). Follow up as scheduled to ensure proper healing and address any concerns about recovery.

Tips for Medical Coders

This code is used for a subsequent encounter of a nondisplaced right tibial tuberosity fracture that is open type I or II with nonunion. Documentation must specify the encounter type (subsequent), fracture type (open I or II), and the presence of nonunion. Ensure the record includes details about the fracture’s status, treatment provided, and any complications to support accurate coding.
