S82.222K Displaced transverse fracture of shaft of left tibia, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Displaced transverse fracture of shaft of left tibia, subsequent encounter for closed fracture with nonunion

Summary

A displaced transverse fracture of the shaft of the left tibia is a break across the main portion of the tibia (shinbone) in the left leg, where the bone fragments are separated and misaligned. This is a subsequent encounter for a closed fracture with nonunion, meaning the fracture site has failed to heal properly after an initial injury, and the skin remains intact without open wounds. Nonunion occurs when the bone fragments do not fuse together within the expected healing timeframe, often requiring additional intervention to promote healing.

Causes

Displaced transverse fractures of the tibial shaft commonly result from direct trauma, such as falls, motor vehicle accidents, or sports injuries. High-energy impacts, like those from contact sports or industrial accidents, can also cause these injuries. Nonunion may develop due to inadequate immobilization, poor blood supply to the fracture site, infection, or underlying conditions that impair bone healing, such as diabetes or smoking.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Previous lower leg injuries or surgeries.
• Age-related bone density loss, particularly in older adults.
• Lack of protective gear during physical activities.
• Chronic conditions like diabetes or smoking that affect bone healing.

Symptoms

• Persistent pain at the fracture site, often lasting beyond the typical healing period.
• Swelling, bruising, or tenderness along the shin that does not resolve.
• Difficulty bearing weight or walking, even with support.
• Visible deformity or misalignment in severe cases.
• Numbness or tingling in the foot (possible nerve involvement).

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and deformity, followed by imaging studies. X-rays are typically used to confirm the fracture and evaluate for nonunion, which is diagnosed when a fracture line remains visible and there is no bridging bone formation after an extended period. Additional tests, such as CT scans or bone scans, may be ordered to assess bone healing and rule out infection.

Treatment Options

Treatment for nonunion may include surgical intervention, such as internal or external fixation to stabilize the fracture, bone grafting to promote healing, or electrical stimulation to encourage bone growth. Non-surgical options, like bracing or casting, may be considered for less severe cases. Physical therapy is often recommended to restore function and strength once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. With proper intervention, many patients achieve successful healing, but recovery may take longer than with uncomplicated fractures. Regular follow-up appointments and imaging are necessary to monitor progress and adjust treatment as needed.

Complications

• Chronic pain or discomfort.
• Persistent instability or deformity.
• Infection, particularly if surgery is required.
• Nerve or vascular damage.
• Limited mobility or functional impairment.

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 and limit alcohol, as these can impair healing.
• Use protective gear during sports or activities to reduce injury risk.
• Follow post-treatment guidelines, including weight-bearing restrictions and physical therapy.

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Sudden, severe pain at the fracture site.
• Increased swelling, redness, or drainage.
• Numbness, tingling, or changes in skin color in the foot or ankle.
• Inability to bear weight or walk, even with support.

Tips for Medical Coders

This code is used for a subsequent encounter for a closed fracture with nonunion of the left tibial shaft. Document the fracture type (displaced transverse), location (left tibia), encounter type (subsequent), and the presence of nonunion. Ensure clinical documentation supports the nonunion diagnosis, as this is a key factor in code assignment.
