S82.034D Nondisplaced transverse fracture of right patella, subsequent encounter for closed fracture with routine healing

Name of the Condition

• Nondisplaced transverse fracture of right patella, subsequent encounter for closed fracture with routine healing

Summary

This condition involves a horizontal break across the right 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 "subsequent encounter" indicates this is a follow-up visit for the fracture, "closed fracture" means the skin over the fracture site is intact, and "routine healing" confirms the fracture is progressing normally 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 right 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, followed by physical therapy to restore strength and mobility.
• Surgical intervention: Rarely required for nondisplaced fractures, but may be considered if alignment is compromised or if the fracture does not heal properly.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, and patients typically regain full function over several weeks to months. Follow-up visits monitor healing progress, and physical therapy helps prevent stiffness and weakness. Routine healing indicates the fracture is progressing as expected.

Complications

• Delayed healing or nonunion.
• Post-traumatic arthritis.
• Chronic pain or stiffness.
• Infection (rare, especially with surgical intervention).

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by using assistive devices if needed.
• Gradually return to activity as advised by a healthcare provider.

When to Seek Professional Help

Seek immediate care if you experience severe pain, swelling, or inability to bear weight after a knee injury. Contact your provider if symptoms worsen or do not improve with treatment, or if you notice signs of infection (e.g., fever, redness, drainage).

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with routine healing. Ensure clinical notes specify the fracture type (nondisplaced transverse), location (right patella), and healing status (routine) to support accurate coding.
