S82.155E Nondisplaced fracture of left tibial tuberosity, subsequent encounter for open fracture type I or II with routine healing

Name of the Condition

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

Summary

A nondisplaced fracture of the left tibial tuberosity involves a break in the bony prominence on the anterior upper tibia where the patellar tendon attaches, with the bone fragments remaining aligned. This encounter is for an open fracture type I or II (skin breach but limited wound) that is healing routinely. Open fractures require monitoring to ensure no infection or complications, while routine healing indicates progress without major issues. The tibial tuberosity is critical for knee extension, and even nondisplaced fractures can affect function temporarily.

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. The open nature of the fracture indicates the skin was penetrated, often by the fractured bone or external force, and this encounter reflects follow-up after initial treatment.

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
• Open wounds near the tibial tuberosity (increasing infection risk during healing)

Symptoms

• Localized pain and swelling over the tibial tuberosity
• Difficulty extending the knee or bearing weight
• Bruising or tenderness on palpation
• Minimal deformity due to nondisplacement
• Possible residual wound care needs if the open fracture is still healing

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 alignment. CT or MRI may be ordered for complex cases. Documentation should note the open fracture type (I or II) and evidence of routine healing, such as reduced swelling, stable alignment, and no signs of infection.

Treatment Options

• Immobilization (e.g., brace or cast) to support healing
• Pain management with medications or physical therapy
• Wound care for the open fracture site if still healing
• Gradual weight-bearing and range-of-motion exercises as healing progresses
• Follow-up imaging to confirm continued alignment and healing

Prognosis and Follow-Up

Prognosis is generally favorable with routine healing, as nondisplaced fractures often recover well with proper care. Follow-up appointments monitor for complications like infection or delayed healing. Most patients regain full knee function, but recovery time varies based on individual factors and adherence to treatment.

Complications

• Infection at the open fracture site
• Delayed healing or nonunion
• Persistent pain or stiffness
• Limited knee mobility
• Rarely, progression to a more severe fracture type

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Use proper protective gear during sports
• Strengthen quadriceps and surrounding muscles to support the knee
• Maintain a healthy weight to reduce stress on the knee joint
• Follow post-injury rehabilitation guidelines to restore function

When to Seek Professional Help

Seek care if experiencing increased pain, swelling, or redness at the fracture site; signs of infection (e.g., fever, pus); or difficulty bearing weight. Worsening symptoms or new deformity also warrant immediate evaluation.

Tips for Medical Coders

Document the fracture type (open I or II), subsequent encounter status, and evidence of routine healing (e.g., stable alignment, no infection). Ensure clinical notes specify the left tibial tuberosity and confirm the fracture remains nondisplaced. Code S82.155E applies to this scenario, with documentation supporting the open fracture classification and healing progress.
