S82.153F Displaced fracture of unspecified tibial tuberosity, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Displaced fracture of unspecified tibial tuberosity, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine 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 (types IIIA, IIIB, or IIIC) with routine healing, indicating the fracture has been treated and is progressing normally. Open fractures involve exposure of the bone through the skin, and routine healing suggests no significant 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 severe trauma where the bone pierces the skin or is otherwise exposed.

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, such as motor vehicle accidents

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
• Open wound or exposed bone (in open fractures)
• 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. For open fractures, evaluation of the wound and surrounding tissues is critical to determine the fracture type (IIIA, IIIB, or IIIC).

Treatment Options

Treatment depends on the severity of the fracture and the type of open fracture. Options may include surgical intervention to realign and stabilize the bone, wound care for open fractures, and physical therapy to restore function. Antibiotics or other medications may be used to prevent infection in open fractures.

Prognosis and Follow-Up

With routine healing, the prognosis is generally favorable, though recovery time varies. Follow-up care includes monitoring for infection, assessing healing progress, and guiding rehabilitation. Physical therapy is often recommended to restore strength and mobility.

Complications

• Infection (especially in open fractures)
• Nonunion or malunion of the fracture
• Chronic pain or stiffness
• Nerve or vascular damage
• Reduced knee function or mobility

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports)
• Maintain bone health through proper nutrition and exercise
• Avoid excessive stress on the knee, especially during growth spurts
• Seek prompt treatment for knee injuries to prevent complications

When to Seek Professional Help

Seek immediate medical attention for severe pain, inability to bear weight, visible deformity, or open wounds. Follow up with a healthcare provider if symptoms worsen or do not improve with treatment.

Tips for Medical Coders

This code is for a subsequent encounter of an open fracture (types IIIA, IIIB, or IIIC) with routine healing. Documentation should specify the fracture type, healing status, and that it is a subsequent encounter. Ensure the record supports the open fracture classification and routine healing to justify the code.
