S82.045S Nondisplaced comminuted fracture of left patella, sequela

Name of the Condition

• Nondisplaced comminuted fracture of left patella, sequela

Summary

This condition represents the residual effects of a previously treated nondisplaced comminuted fracture of the left patella (kneecap). The fracture involved multiple bone fragments without significant displacement, and the "sequela" designation indicates ongoing consequences or complications following the initial injury and treatment. The severity and impact depend on the original fracture pattern, healing, and any resulting functional limitations.

Causes

The underlying cause is a prior nondisplaced comminuted fracture of the left patella, typically resulting from direct trauma (e.g., falls, high-impact injuries) or muscle contractions. The sequela arises from incomplete healing, residual bone fragments, or persistent functional impairment after the acute injury has resolved.

Risk Factors

• Pre-existing osteoporosis or bone-weakening conditions.
• Advanced age, which may impair bone healing.
• Inadequate initial treatment or rehabilitation.
• High-impact activities or sports that stress the knee.
• Previous knee injuries or surgeries affecting the patella.

Symptoms

• Chronic left knee pain or discomfort, especially with activity.
• Reduced range of motion or stiffness in the left knee.
• Mild swelling or tenderness around the patella.
• Difficulty bearing weight or performing daily tasks.
• Possible visible or palpable irregularities in the patella area.

Diagnosis

Diagnosis involves a clinical evaluation of the left knee, focusing on pain, range of motion, and functional limitations. Imaging (e.g., X-rays, CT scans) may be used to assess residual bone fragments, alignment, or signs of malunion. Documentation should confirm the history of the original fracture and its sequelae.

Treatment Options

• Physical therapy to improve strength, flexibility, and function.
• Pain management with medications or modalities (e.g., ice, heat).
• Orthotic devices (e.g., knee braces) for support during activity.
• Surgical intervention (e.g., fragment removal or realignment) if severe functional impairment persists.

Prognosis and Follow-Up

Prognosis varies based on the extent of residual damage and adherence to rehabilitation. Most patients experience improved function with therapy, though some may have long-term limitations. Regular follow-up with a healthcare provider is recommended to monitor healing and adjust treatment as needed.

Complications

• Chronic pain or arthritis in the left knee.
• Persistent stiffness or reduced mobility.
• Risk of re-injury due to weakened bone or altered mechanics.
• Need for additional surgery if complications (e.g., nonunion) develop.

Lifestyle & Prevention

• Avoid high-impact activities that stress the knee.
• Maintain a healthy weight to reduce joint load.
• Use proper footwear and protective gear during sports.
• Follow a gradual, supervised rehabilitation program post-injury.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling occurs, or functional limitations interfere with daily life. Prompt evaluation is necessary for sudden changes in knee function or signs of infection.

Tips for Medical Coders

This code (S82.045S) is used for the sequela of a nondisplaced comminuted left patella fracture. Documentation must specify the residual effects (e.g., chronic pain, limited mobility) and link them to the original injury. Ensure the "sequela" designation is supported by clinical evidence of ongoing consequences, not just the history of the fracture.
