S82.151E Displaced fracture of right tibial tuberosity, subsequent encounter for open fracture type I or II with routine healing

Name of the Condition

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

Summary

A displaced fracture of the right tibial tuberosity involves a break in the bony prominence on the anterior upper tibia where the patellar tendon attaches. This specific ICD code refers to a subsequent encounter for an open fracture type I or II with routine healing, meaning the fracture has progressed to a healing phase after initial treatment. Displacement indicates the bone fragments are misaligned, and the open fracture classification denotes a break in the skin with minimal contamination. Routine healing suggests the fracture is progressing without complications.

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 high-energy trauma that breaches the skin, while subsequent encounters reflect ongoing care during the healing process.

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 that breaches the skin, increasing risk of open fractures

Symptoms

• Persistent pain and swelling over the tibial tuberosity during healing
• Gradual improvement in knee extension and weight-bearing ability
• Minimal or no open wound present (type I or II open fracture)
• Tenderness at the fracture site on palpation
• Possible residual deformity or prominence

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 may be ordered to assess soft tissue damage or healing progress. Documentation must specify the fracture type (open I or II) and routine healing status to support the code.

Treatment Options

Treatment typically includes immobilization with a cast or brace to stabilize the fracture. Physical therapy may be recommended to restore knee function and strength. Routine follow-up appointments monitor healing progress, and pain management strategies are employed as needed. Surgical intervention is less common in subsequent encounters unless complications arise.

Prognosis and Follow-Up

Prognosis is generally favorable with routine healing, though recovery time varies based on fracture severity and patient factors. Follow-up care focuses on monitoring healing, assessing functional recovery, and adjusting treatment plans as needed. Most patients regain full knee function with appropriate care, but residual stiffness or weakness may persist.

Complications

• Delayed union or nonunion of the fracture
• Infection at the open fracture site
• Persistent pain or stiffness
• Malunion or misalignment of bone fragments
• Tendon or ligament damage affecting knee stability

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Use protective gear during sports to reduce injury risk
• Maintain bone health through proper nutrition and exercise
• Follow rehabilitation guidelines to optimize healing
• Gradually return to activity under medical supervision

When to Seek Professional Help

Seek immediate medical attention if symptoms worsen, such as increased pain, swelling, or signs of infection (e.g., fever, redness). Contact a healthcare provider if knee function does not improve or if new deformity or instability develops.

Tips for Medical Coders

Document the fracture type (open I or II) and routine healing status clearly in the medical record. Ensure the encounter is classified as "subsequent" to reflect ongoing care after initial treatment. Code S82.151E requires specificity about the fracture's progression and healing phase to align with clinical documentation.
