S82.153A Displaced fracture of unspecified tibial tuberosity, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of unspecified tibial tuberosity, initial encounter for closed fracture
• Medical term: Displaced fracture of tibial tuberosity

Summary

A displaced fracture of the tibial tuberosity involves a break in the bony prominence on the anterior tibia where the patellar tendon attaches. Displacement means the bone fragments are misaligned. This code specifies an initial encounter for a closed fracture, where the skin remains intact and the fracture is not exposed.

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.

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

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

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.

Treatment Options

• Immobilization with a brace or cast to stabilize the fracture
• Pain management with analgesics or anti-inflammatory medications
• Physical therapy to restore range of motion and strength
• Surgical intervention if the fracture is severely displaced or unstable

Prognosis and Follow-Up

Most displaced fractures of the tibial tuberosity heal with proper treatment, but recovery time varies. Follow-up care includes monitoring for healing progress and gradual return to activity. Long-term outcomes depend on the severity of the fracture and adherence to rehabilitation.

Complications

• Nonunion or delayed healing of the fracture
• Chronic pain or stiffness in the knee
• Damage to surrounding nerves or blood vessels
• Post-traumatic arthritis in severe cases

Lifestyle & Prevention

• Use proper protective gear during sports or high-risk activities
• Strengthen knee muscles through targeted exercises
• Avoid sudden, forceful movements that strain the knee
• Maintain bone health with adequate nutrition and exercise

When to Seek Professional Help

Seek immediate medical attention if you experience severe knee pain, swelling, or inability to bear weight after an injury. Prompt evaluation is important to prevent complications and ensure proper treatment.

Tips for Medical Coders

This code (S82.153A) is for a displaced fracture of the unspecified tibial tuberosity, initial encounter for a closed fracture. Document the fracture type (displaced), location (unspecified tibial tuberosity), and encounter type (initial for closed fracture) to support accurate coding. Ensure clinical documentation aligns with the code’s specificity.
