S82.035D Nondisplaced transverse fracture of left patella, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Nondisplaced 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), a triangular bone that protects the knee joint. The fracture line runs perpendicular to the bone’s long axis, and the bone fragments remain aligned in their normal position. The term "subsequent encounter" indicates this is a follow-up visit for the fracture, and "closed fracture with routine healing" means the skin over the fracture site is intact and the fracture is healing as expected without complications.

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 (initial injury).
• Swelling and bruising around the kneecap.
• Inability to straighten the knee or bear weight (initial injury).
• Visible deformity or a gap in the kneecap area (initial injury).
• A "popping" sensation at the time of injury (initial 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, pain management, and physical therapy to restore strength and mobility.
• Surgical intervention: Rarely required for nondisplaced fractures, but may be considered if alignment is compromised or if there are associated injuries.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment. Follow-up visits monitor healing progress, and physical therapy helps restore function. Full recovery typically takes several weeks to months, depending on the individual’s health and adherence to treatment.

Complications

• Delayed healing or nonunion.
• Arthritis in the knee joint.
• Chronic pain or stiffness.
• Infection (rare, especially with closed fractures).

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by improving balance and home safety.
• Gradually return to activity as advised by a healthcare provider.

When to Seek Professional Help

• Persistent or worsening pain.
• Increased swelling, redness, or warmth around the knee.
• Inability to bear weight or move the knee.
• Signs of infection, such as fever or pus.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with routine healing. Ensure the fracture is confirmed as nondisplaced and transverse, and note the left patella involvement. Include details about healing progress and any follow-up care provided.
