S82.035A Nondisplaced transverse fracture of left patella, initial encounter for closed fracture

Name of the Condition

• Nondisplaced transverse fracture of left patella, initial encounter for closed fracture

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 without displacement. The term "initial encounter" indicates this is the first time the patient is receiving treatment for the fracture, and "closed fracture" means the skin over the fracture site is intact.

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 to allow healing. Physical therapy to restore strength and mobility once the fracture stabilizes.
• Surgical intervention: Rarely required for nondisplaced fractures, but may be considered if the fracture is unstable or fails to heal with conservative treatment.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, and patients can expect a full recovery with proper rehabilitation. Follow-up appointments are necessary to monitor healing and adjust treatment plans as needed.

Complications

• Delayed healing or nonunion of the fracture.
• Post-traumatic arthritis due to joint damage.
• Chronic pain or stiffness in the knee.
• Infection (rare, especially with surgical intervention).

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through a balanced diet and regular exercise.
• Avoid falls by using assistive devices if needed, especially in older adults.

When to Seek Professional Help

Seek immediate medical attention if you experience severe knee pain, swelling, or an inability to bear weight after an injury. Prompt evaluation is important to rule out other injuries and ensure proper treatment.

Tips for Medical Coders

This code is specific to a nondisplaced transverse fracture of the left patella, with the encounter classified as initial and the fracture as closed. Documentation should clearly indicate the fracture type, location, displacement status, and encounter stage to support accurate coding. Ensure the left side and closed nature of the fracture are explicitly documented.
