S82.123G Displaced fracture of lateral condyle of unspecified tibia, subsequent encounter for closed fracture with delayed healing

Name of the Condition

Displaced fracture of lateral condyle of unspecified tibia, subsequent encounter for closed fracture with delayed healing

Summary

This condition involves a displaced fracture of the lateral condyle of the tibia, a bony prominence on the outer side of the upper tibia that contributes to knee joint stability. The fracture is displaced, meaning the bone fragments are out of their normal alignment, and it is classified as a closed fracture (no open wound) during a subsequent encounter. The "delayed healing" modifier indicates the fracture has not progressed as expected in the healing process.

Causes

Traumatic injury to the knee, such as falls, sports-related impacts, or motor vehicle accidents, is the primary cause. Direct force to the lateral knee or twisting injuries can lead to this fracture. Delayed healing may result from factors like inadequate immobilization, poor blood supply to the fracture site, or underlying health conditions affecting bone repair.

Risk Factors

• Participation in high-impact or contact sports.
• 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 (e.g., diabetes) that affect tissue repair.

Symptoms

• Persistent pain, swelling, and tenderness localized to the lateral knee.
• Difficulty bearing weight on the affected leg.
• Possible visible deformity or misalignment.
• Bruising or discoloration around the injury site.
• Limited range of motion in the knee joint.

Diagnosis

Physical examination to assess pain, swelling, and joint stability. Imaging tests, such as X-rays or CT scans, to evaluate fracture type, displacement, and signs of delayed healing (e.g., lack of callus formation). Additional tests (e.g., blood work) may be used to identify underlying causes of delayed healing.

Treatment Options

• Prolonged immobilization with a cast or brace to support healing.
• Surgical intervention to realign and stabilize the fracture if displacement persists.
• Bone grafting or other procedures to promote healing in severe cases.
• Physical therapy to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture and the underlying cause of delayed healing. Most fractures eventually heal with appropriate treatment, but recovery may take longer than usual. Regular follow-up appointments and imaging are necessary to monitor progress. Full return to normal activities may be delayed.

Complications

• Nonunion (failure of the fracture to heal).
• Malunion (healing in an incorrect position).
• Chronic pain or arthritis in the knee joint.
• Reduced mobility or stiffness.
• Infection (if surgical intervention is required).

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it impairs healing.
• Use protective gear during sports or activities with fall risks.
• Follow rehabilitation guidelines to restore strength and function.

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Severe or worsening pain.
• Increased swelling, redness, or drainage from the injury site.
• Inability to bear weight on the affected leg.
• Signs of infection (e.g., fever, chills).
• Sudden changes in the appearance of the knee (e.g., new deformity).

Tips for Medical Coders

This code (S82.123G) is used for a subsequent encounter of a displaced lateral condyle tibia fracture that is closed and has delayed healing. Documentation should specify the fracture type, encounter stage (subsequent), and the presence of delayed healing. Ensure the record includes details about the fracture’s status and any contributing factors to support the delayed healing modifier.
