S82.155S Nondisplaced fracture of left tibial tuberosity, sequela

Name of the Condition

• Nondisplaced fracture of left tibial tuberosity, sequela

Summary

A nondisplaced fracture of the left tibial tuberosity, sequela, refers to the residual effects of a prior fracture of the bony prominence on the anterior upper tibia where the patellar tendon attaches. The bone fragments remained aligned during the initial injury, and this code is used for the long-term consequences of that healed fracture. Sequela may include persistent pain, functional limitations, or other chronic changes resulting from the original injury.

Causes

The sequela arises from a previous nondisplaced fracture of the left tibial tuberosity, which typically resulted from trauma such as direct impact to the knee, falls, or sudden forceful contraction of the quadriceps muscle. The original injury may have occurred during sports, accidents, or other high-stress activities.

Risk Factors

• History of prior knee trauma or fracture
• Participation in activities with repetitive knee stress (e.g., jumping, running)
• Adolescent growth spurts (if the original fracture occurred during this period)
• Inadequate rehabilitation or incomplete healing of the initial fracture

Symptoms

• Chronic localized pain or discomfort over the tibial tuberosity
• Mild swelling or tenderness on palpation
• Reduced knee extension strength or range of motion
• Occasional instability or stiffness during activity

Diagnosis

Diagnosis involves a review of the patient’s medical history to confirm a prior fracture and assessment of current symptoms. Physical examination evaluates pain, swelling, and functional limitations. Imaging studies, such as X-rays, may be used to assess residual bony changes or alignment. Clinical correlation with the history of the original injury is essential.

Treatment Options

Treatment focuses on managing symptoms and improving function. Options may include physical therapy to strengthen surrounding muscles, activity modification, pain management, and orthotic devices. In some cases, surgical intervention may be considered for persistent functional impairment.

Prognosis and Follow-Up

Prognosis depends on the severity of residual effects and adherence to treatment. Most patients experience improvement with conservative management, though some may have long-term mild limitations. Follow-up care involves monitoring symptoms and functional progress, with adjustments to treatment as needed.

Complications

• Chronic pain or discomfort
• Reduced knee mobility or strength
• Increased risk of future knee injuries due to altered biomechanics
• Rarely, persistent swelling or deformity

Lifestyle & Prevention

• Engage in regular low-impact exercise to maintain knee strength and flexibility
• Use proper footwear and technique during physical activities
• Avoid sudden, high-impact movements that stress the knee
• Follow rehabilitation guidelines after any knee injury to minimize long-term effects

When to Seek Professional Help

Seek medical attention if symptoms worsen, new pain or swelling develops, or functional limitations interfere with daily activities. Prompt evaluation is important if there is suspicion of a new injury or infection.

Tips for Medical Coders

This code is used for the sequela (residual effect) of a prior nondisplaced fracture of the left tibial tuberosity. Documentation should clearly indicate the history of the original fracture and the current residual symptoms or functional changes. Ensure the code is applied only when the condition is a direct result of the prior injury and not an acute or new fracture.
