S82.012G Displaced osteochondral fracture of left patella, subsequent encounter for closed fracture with delayed healing

Name of the Condition

• Displaced osteochondral fracture of left patella, subsequent encounter for closed fracture with delayed healing

Summary

This condition involves a displaced fracture of the left patella (kneecap) that includes damage to the adjacent cartilage (osteochondral injury). The fracture is closed, meaning the skin is intact, and it is a subsequent encounter for this specific injury with delayed healing. Displacement indicates that bone fragments are out of their normal alignment, and delayed healing suggests the fracture is not progressing as expected during the recovery phase.

Causes

Direct trauma to the knee, such as a fall onto the kneecap, a forceful blow, or a high-impact injury (e.g., motor vehicle accident or sports injury). The displacement occurs when the force is sufficient to separate the bone-cartilage fragment from the main patella. Delayed healing may result from inadequate immobilization, poor blood supply to the fracture site, or underlying health conditions affecting bone repair.

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.
• Smoking or poor nutrition, which can impair healing.
• Certain medical conditions, such as diabetes or vascular disease.

Symptoms

• Persistent pain in the left knee, especially with movement or weight-bearing.
• Swelling and bruising around the kneecap that may not improve over time.
• Limited range of motion in the left knee, difficulty straightening or bending.
• Possible instability or a feeling of the knee "giving way."
• Tenderness to touch over the patella.

Diagnosis

A physical examination to assess knee movement, swelling, and tenderness. Imaging studies, typically X-rays, to confirm the fracture and evaluate bone alignment. CT or MRI may be used to assess cartilage damage or healing progress. Blood tests or additional imaging may be ordered if an underlying condition affecting healing is suspected.

Treatment Options

• Immobilization with a brace or cast to stabilize the fracture and promote healing.
• Pain management with medications or physical therapy to reduce discomfort and improve mobility.
• Surgical intervention, such as internal fixation, if the fracture remains displaced or healing does not progress.
• Monitoring with regular follow-up imaging to assess healing status.
• Addressing underlying factors, such as nutritional deficiencies or medical conditions, that may delay recovery.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, adherence to treatment, and any underlying health issues. Most fractures with delayed healing eventually heal with proper care, but recovery may take longer than usual. Follow-up appointments are essential to monitor progress and adjust treatment as needed. Physical therapy is often recommended to restore strength and function once healing is underway.

Complications

• Nonunion, where the fracture fails to heal completely.
• Malunion, where the bone heals in an incorrect position.
• Post-traumatic arthritis due to cartilage damage.
• Chronic pain or stiffness in the knee.
• Infection (rare, but possible if surgery is performed).

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or activities with a risk of knee injury.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it can impair healing.
• Follow a physical therapy program to strengthen the knee and prevent future injuries.

When to Seek Professional Help

• If pain worsens or does not improve with treatment.
• If swelling, bruising, or instability increases.
• If you experience fever, redness, or drainage from the knee (signs of infection).
• If you cannot bear weight on the left knee or have difficulty moving it.
• If symptoms return after initial improvement.

Tips for Medical Coders

This code represents a subsequent encounter for a closed displaced osteochondral fracture of the left patella with delayed healing. Documentation should specify the fracture type (closed), the encounter type (subsequent), and the healing status (delayed). Coders should verify that the medical record supports the delayed healing diagnosis, as this is a key component of the code. Ensure alignment with ICD-10-CM guidelines for fracture coding, including the correct laterality (left) and encounter status.
