S82.032D Displaced transverse fracture of left patella, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Displaced transverse fracture of left patella, subsequent encounter for closed fracture with routine healing

Summary

This condition involves a horizontal break across the left kneecap (patella), with the bone fragments displaced from their normal alignment. The fracture is closed, meaning the skin is intact, and this is a subsequent encounter for treatment, indicating the fracture is healing as expected. The patella, a triangular bone protecting the knee joint, is fractured transversely, with the break running perpendicular to its long axis.

Causes

Direct trauma to the knee, such as a fall onto the kneecap, a blow from an object, or a forceful contraction of the quadriceps muscle. High-impact injuries, like those from sports or motor vehicle accidents, are common triggers.

Risk Factors

• Participation in activities with a high risk of knee injury, such as contact sports or skiing.
• Osteoporosis or other bone-weakening conditions.
• Previous knee injuries or surgeries.
• Advanced age, which may reduce bone density.

Symptoms

• Sudden, severe pain in the left knee.
• Swelling and bruising around the kneecap.
• Inability to straighten the knee or bear weight.
• Visible deformity or a gap in the kneecap area.
• A "popping" sensation at the time of injury.

Diagnosis

A physical examination to assess knee movement, swelling, and tenderness. Imaging studies, typically X-rays, to confirm the fracture and evaluate bone alignment. In some cases, a CT scan may be used to assess complex fractures or displacement.

Treatment Options

• Conservative management: Immobilization with a cast or brace, followed by physical therapy to restore strength and mobility.
• Surgical intervention: Internal fixation with screws or wires if the fracture is unstable or fails to heal properly.
• Pain management: Medications to reduce discomfort and inflammation.

Prognosis and Follow-Up

Most fractures heal with proper treatment, and patients often regain full knee function. Follow-up appointments monitor healing progress, typically with imaging studies to confirm bone union. Physical therapy is recommended to restore range of motion and strength.

Complications

• Nonunion or delayed healing of the fracture.
• Arthritis in the knee joint due to misalignment.
• Chronic pain or stiffness.
• Infection (rare, especially if surgery is performed).

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by using assistive devices if needed.
• Strengthen knee muscles to improve stability.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or if there is new numbness or tingling. Contact a healthcare provider if the knee cannot bear weight or if there are signs of infection, such as redness or fever.

Tips for Medical Coders

Document the fracture type (displaced transverse), laterality (left), encounter type (subsequent), and healing status (routine healing). Ensure clinical notes specify closed fracture and confirm the fracture is healing without complications to support the code.
