S82.154F Nondisplaced fracture of right tibial tuberosity, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Nondisplaced fracture of right tibial tuberosity, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

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 injury is classified as an open fracture type IIIA, IIIB, or IIIC, meaning the skin over the fracture site is compromised with significant soft tissue damage. The encounter is subsequent, indicating follow-up care, and healing is proceeding routinely. The tibial tuberosity is critical for knee extension, and even nondisplaced fractures can impact function.

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, often with extensive soft tissue injury.

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
• Conditions that weaken bone or soft tissue

Symptoms

• 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 signs of infection in open fractures

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 used to assess soft tissue damage in open fractures. Documentation must specify the fracture type (IIIA, IIIB, or IIIC) and confirm routine healing during the subsequent encounter.

Treatment Options

Treatment focuses on managing pain, promoting healing, and restoring function. This may include immobilization with a brace or cast, physical therapy to maintain mobility, and monitoring for infection in open fractures. Surgical intervention may be required for severe soft tissue damage or nonunion, though nondisplaced fractures often heal with conservative care.

Prognosis and Follow-Up

Prognosis is generally favorable with routine healing, especially for nondisplaced fractures. Follow-up care ensures proper healing and functional recovery. Regular monitoring for complications, such as infection or delayed union, is essential. Most patients regain full knee function with appropriate treatment and rehabilitation.

Complications

• Infection, particularly in open fractures
• Delayed healing or nonunion
• Chronic pain or stiffness
• Soft tissue damage or scarring
• Reduced knee mobility or strength

Lifestyle & Prevention

• Use protective gear during high-impact activities
• Strengthen quadriceps and surrounding muscles
• Avoid sudden, forceful knee movements
• Maintain bone health through proper nutrition and exercise
• Seek prompt treatment for knee injuries to prevent complications

When to Seek Professional Help

Seek immediate medical attention if experiencing severe pain, inability to bear weight, visible wound at the fracture site, signs of infection (e.g., redness, pus), or worsening symptoms during recovery.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and confirm routine healing during the subsequent encounter. Ensure the code reflects the right tibial tuberosity, nondisplaced status, open fracture classification, and subsequent encounter for healing. Clinical documentation must support the fracture type and healing progress to justify the code.
