S82.151F Displaced fracture of right tibial tuberosity, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Displaced fracture of right tibial tuberosity, subsequent encounter for open fracture type IIIA, IIIB, or IIIC 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 (types IIIA, IIIB, or IIIC) with routine healing, indicating the fracture site is healing as expected after initial treatment. Displacement means the bone fragments are misaligned, and the open fracture classification denotes varying degrees of soft tissue damage and bone exposure.

Causes

Traumatic injury is the primary cause, such as direct impact to the knee, falls, or sudden forceful contraction of the quadriceps muscle. High-energy trauma, including motor vehicle accidents or sports-related incidents, can lead to open fractures with significant soft tissue involvement. The open fracture types (IIIA, IIIB, IIIC) reflect increasing severity of soft tissue damage and potential contamination.

Risk Factors

• Participation in high-impact activities or contact sports (e.g., basketball, soccer)
• Adolescent growth spurts, particularly in athletes, which may weaken the growth plate
• Previous knee injuries or surgeries that compromise tissue integrity
• Conditions affecting bone strength or soft tissue healing (e.g., diabetes, vascular disease)
• High-energy trauma exposure, increasing the likelihood of open fractures

Symptoms

• Persistent pain and swelling over the tibial tuberosity, though may be reduced compared to initial injury
• Limited knee extension or difficulty bearing weight on the affected limb
• Visible deformity or abnormal positioning at the fracture site
• Bruising or discoloration in the affected area
• Possible residual soft tissue changes from the open fracture (e.g., scarring, altered sensation)

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity, with attention to healing progress. Imaging studies, such as X-rays, are used to confirm fracture alignment and healing status. Additional tests like MRI or CT may be ordered to evaluate soft tissue healing or residual damage. Documentation should reflect the open fracture type and routine healing trajectory.

Treatment Options

Treatment focuses on maintaining fracture alignment and promoting healing. This may include immobilization (e.g., casting or bracing), physical therapy to restore function, and monitoring for complications. Surgical intervention is less common in subsequent encounters unless malunion or nonunion occurs. Wound care for residual soft tissue changes from the open fracture may be necessary.

Prognosis and Follow-Up

Prognosis is generally favorable with routine healing, though residual stiffness or weakness may persist. Follow-up care involves regular assessments to monitor healing, functional recovery, and address any ongoing symptoms. Physical therapy is often recommended to restore knee mobility and strength. Long-term outcomes depend on the severity of the initial injury and adherence to rehabilitation.

Complications

• Malunion or nonunion of the fracture
• Persistent knee stiffness or reduced range of motion
• Chronic pain or instability
• Infection (rare, but possible with open fracture history)
• Soft tissue scarring or nerve damage from the initial injury

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Engage in low-impact exercises (e.g., swimming, cycling) to maintain fitness during healing
• Use proper protective gear during sports or activities with fall risks
• Strengthen surrounding muscles (e.g., quadriceps, hamstrings) to support knee stability
• Maintain a healthy weight to reduce stress on the knee joint

When to Seek Professional Help

Seek medical attention if you experience increasing pain, swelling, or deformity, or if you notice signs of infection (e.g., redness, warmth, pus) at the fracture site. Contact your provider if you have difficulty bearing weight, reduced knee mobility, or concerns about healing progress.

Tips for Medical Coders

This code is specific to a subsequent encounter for an open fracture (types IIIA, IIIB, or IIIC) with routine healing. Documentation should clearly indicate the fracture type, healing status, and that this is a follow-up visit. Ensure the record specifies "subsequent encounter" and confirms the open fracture classification to support accurate coding. Note that routine healing implies no complications or delayed union.
