S92.115A Nondisplaced fracture of neck of left talus, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of neck of left talus, initial encounter for closed fracture

Summary

A nondisplaced fracture of the neck of the left talus is a break in the narrow portion of the talus bone on the left side, where the bone fragments remain in their normal alignment. The talus is a critical bone in the ankle joint, connecting the foot to the lower leg and supporting weight-bearing and movement. This type of fracture is considered closed, meaning the skin is intact, and it is the initial encounter for treatment. Nondisplaced fractures typically involve less disruption to joint surfaces compared to displaced fractures.

Causes

Direct trauma to the ankle, such as falls, sports injuries, or motor vehicle accidents, is the most common cause. High-impact forces or twisting motions can lead to this type of fracture, particularly in activities involving sudden stops or changes in direction. The injury may result from a single event or repetitive stress over time.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer) or activities with a risk of ankle injury.
• Osteoporosis or other conditions that weaken bone density.
• Previous ankle or talus injuries.
• Improper footwear or inadequate protective gear during physical activities.

Symptoms

• Sudden, severe pain in the ankle or foot.
• Swelling and bruising around the injury site.
• Difficulty bearing weight or walking.
• Limited range of motion in the ankle joint.
• Possible deformity or abnormal positioning of the foot.

Diagnosis

A healthcare provider will perform a physical examination to assess pain, swelling, and mobility. Imaging studies, such as X-rays or CT scans, are typically used to confirm the fracture and determine if it is nondisplaced. The provider will evaluate the alignment of the bone fragments and check for associated injuries to the surrounding tissues.

Treatment Options

Treatment for a nondisplaced fracture of the neck of the left talus often includes immobilization with a cast or brace to allow the bone to heal. Non-weight-bearing status may be recommended for a period to reduce stress on the injury. Pain management and physical therapy may be prescribed to restore function and strength once healing progresses. In some cases, surgical intervention may be necessary if the fracture does not heal properly or if there are complications.

Prognosis and Follow-Up

The prognosis for a nondisplaced fracture of the neck of the left talus is generally favorable, especially with proper treatment and adherence to weight-bearing restrictions. Most patients recover fully, but healing time can vary depending on the severity of the injury. Follow-up appointments are important to monitor healing and adjust treatment as needed. Long-term outcomes may include restored mobility and reduced risk of future complications, though some patients may experience residual stiffness or pain.

Complications

Potential complications include delayed healing, nonunion (failure of the bone to heal), or avascular necrosis (loss of blood supply to the talus). Infection or nerve damage may occur, though these are less common with closed fractures. Chronic pain or arthritis in the ankle joint is also a possible long-term risk.

Lifestyle & Prevention

To reduce the risk of talus fractures, wear appropriate footwear and protective gear during high-impact activities. Maintain bone health through a balanced diet rich in calcium and vitamin D, and engage in regular weight-bearing exercise to strengthen bones. Avoid activities that increase the risk of falls or ankle injuries, and seek prompt medical attention for any ankle trauma.

When to Seek Professional Help

Seek immediate medical care if you experience severe pain, swelling, or inability to bear weight after an ankle injury. Contact a healthcare provider if symptoms worsen or do not improve with initial treatment, or if you notice signs of infection, such as redness, warmth, or drainage from the injury site.

Tips for Medical Coders

When coding for a nondisplaced fracture of the neck of the left talus, use the ICD-10-CM code S92.115A. Ensure documentation specifies the fracture is nondisplaced, located on the left talus, and is the initial encounter for a closed fracture. Verify that the encounter type (initial) and fracture status (closed) are clearly documented to support accurate coding.
