S82.014R Nondisplaced osteochondral fracture of right patella, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion

Name of the Condition

• Nondisplaced osteochondral fracture of right patella, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with malunion

Summary

This condition involves a fracture of the right patella (kneecap) where the bone and overlying cartilage are damaged but remain in their original position (nondisplaced). The fracture is classified as open (type IIIA, IIIB, or IIIC), indicating significant soft tissue damage, and is a subsequent encounter for the injury with malunion (healing in a non-anatomical position). The injury affects both bony and cartilaginous structures, requiring attention to the fracture, open wound, and malunion.

Causes

Direct trauma to the right 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 open nature of the fracture occurs when the force is sufficient to break the skin while causing the osteochondral injury. Malunion may result from inadequate initial treatment, poor healing, or excessive movement during recovery.

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.
• Delayed or inadequate initial fracture management.

Symptoms

• Persistent pain in the right knee, often localized to the kneecap.
• Swelling and bruising around the kneecap.
• Difficulty straightening or bearing weight on the right knee.
• Visible deformity or abnormal contour of the kneecap due to malunion.
• Open wound over the kneecap (if still present or recently healed).
• A "popping" sensation at the time of injury (may be reported in history).

Diagnosis

A physical examination to assess knee movement, swelling, tenderness, and deformity. Imaging studies, typically X-rays, to evaluate the fracture alignment, malunion, and bone healing. CT or MRI may be used to assess cartilage damage or soft tissue involvement. Documentation of the open fracture type (IIIA, IIIB, or IIIC) and malunion is critical for accurate coding.

Treatment Options

• Immobilization with a brace or cast to stabilize the knee and promote healing.
• Pain management with medications or physical therapy.
• Surgical intervention (e.g., osteotomy, bone grafting) may be considered for significant malunion or functional impairment.
• Wound care for open fractures, including debridement or closure as needed.
• Rehabilitation to restore knee strength and range of motion.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion, functional impact, and response to treatment. Follow-up visits are necessary to monitor healing, assess knee function, and adjust treatment. Long-term outcomes may include persistent pain, reduced mobility, or the need for additional surgery if malunion causes significant disability.

Complications

• Chronic pain or stiffness in the knee.
• Arthritis due to cartilage damage or malunion.
• Infection (if open fracture is present).
• Reduced range of motion or functional limitations.
• Need for additional surgery to correct malunion.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or activities with knee injury risk.
• Maintain bone health through diet and exercise (e.g., calcium, vitamin D).
• Follow post-injury rehabilitation protocols to optimize healing.

When to Seek Professional Help

Seek immediate medical attention for severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., fever, increased redness, drainage). Follow up with a healthcare provider if symptoms worsen or do not improve with treatment.

Tips for Medical Coders

Document the subsequent encounter status, open fracture type (IIIA, IIIB, or IIIC), and malunion clearly. Ensure the code S82.014R is used only when the encounter is for treatment of the malunion following an open fracture. Verify that the fracture remains nondisplaced and that the open fracture type is accurately specified in the medical record.
