S92.154G Nondisplaced avulsion fracture (chip fracture) of right talus, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced avulsion fracture (chip fracture) of right talus, subsequent encounter for fracture with delayed healing

Summary

A nondisplaced avulsion fracture (chip fracture) of the right talus is a type of fracture where a small piece of bone is pulled away from the talus, typically due to ligament or tendon attachment. This injury involves trauma to the ankle joint and may affect mobility and weight-bearing ability, depending on the size and location of the avulsed fragment. The term "nondisplaced" indicates the bone fragment remains in its original position, which generally preserves joint alignment and stability. The "subsequent encounter for fracture with delayed healing" specifies this is a follow-up visit for a fracture that is not healing at the expected rate.

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 also lead to avulsion fractures, particularly in activities involving sudden stops or changes in direction. The fracture occurs when a ligament or tendon pulls a small bone fragment from the talus.

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 evaluate healing progress. The provider may also review the patient's medical history and prior treatment to determine if healing is delayed.

Treatment Options

Treatment may include immobilization with a cast or brace to stabilize the ankle and promote healing. Pain management with medications or physical therapy may be recommended to restore function. In some cases, surgery may be necessary if the fracture does not heal with conservative measures.

Prognosis and Follow-Up

The prognosis depends on the severity of the fracture and the patient's overall health. Delayed healing may require extended follow-up and adjustments to treatment. Most patients recover with proper care, but recovery time can vary. Regular monitoring by a healthcare provider is important to assess healing progress.

Complications

Potential complications include chronic pain, arthritis, or nonunion (failure of the bone to heal). Infection or nerve damage may occur if surgery is performed. Delayed healing increases the risk of long-term joint problems.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use proper footwear and protective gear during sports or physical activities.
• Maintain bone health through a balanced diet and regular exercise.
• Follow rehabilitation guidelines to restore strength and mobility.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to bear weight. Contact a healthcare provider if symptoms worsen or do not improve with treatment, or if you notice signs of infection (e.g., fever, increased redness).

Tips for Medical Coders

This code is used for a nondisplaced avulsion fracture of the right talus during a subsequent encounter when healing is delayed. Documentation should specify the fracture type, location, and the reason for delayed healing (e.g., inadequate blood supply, patient factors). Ensure the encounter is classified as "subsequent" and not initial or acute.
