S82.002K Unspecified fracture of left patella, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Unspecified fracture of left patella, subsequent encounter for closed fracture with nonunion

Summary

This condition refers to a fracture of the left kneecap (patella) that has not healed properly (nonunion) and is being managed in a subsequent encounter. The term "closed fracture" indicates the skin over the fracture remains intact, and "unspecified" means specific details about the fracture type or displacement are not documented.

Causes

Direct trauma to the knee, such as a fall, blow, or high-impact injury, is the typical cause. Nonunion may result from inadequate immobilization, poor blood supply to the bone, or other factors that impede healing.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Previous knee injuries or surgeries.
• Advanced age, which may reduce bone density.
• Smoking or poor nutrition, which can affect bone healing.

Symptoms

• Persistent pain in the knee, especially with movement.
• Swelling and bruising around the kneecap.
• Difficulty straightening or bending the knee.
• Tenderness to touch the patella area.
• Possible instability or clicking in the knee.

Diagnosis

Diagnosis involves a physical examination to assess knee function and tenderness, followed by imaging studies like X-rays to confirm the fracture and assess for nonunion. Additional tests, such as CT scans or MRI, may be used if further detail is needed.

Treatment Options

• Immobilization with a brace or cast to support healing.
• Pain management with medications or ice.
• Physical therapy to restore mobility and strength.
• Surgical intervention, such as bone grafting or internal fixation, if nonunion persists.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Regular follow-up with imaging is typically required to monitor healing. Long-term outcomes may include persistent pain or reduced knee function if healing is incomplete.

Complications

• Chronic pain or instability in the knee.
• Increased risk of arthritis in the knee joint.
• Potential need for additional surgery if nonunion does not resolve.
• Reduced mobility or activity limitations.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Use protective gear during sports or activities that risk knee injury.
• Follow post-treatment guidelines to promote proper healing.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility declines. Immediate attention is needed for signs of infection, such as fever, redness, or drainage from the knee.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Ensure the medical record specifies the fracture is closed and that nonunion is present. Include details about treatment provided and any imaging results to support the diagnosis.
