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

Name of the Condition

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

Summary

A nondisplaced avulsion fracture (chip fracture) of the right talus, subsequent encounter for fracture with routine healing, refers to a fracture where a small bone fragment is pulled away from the talus but remains in its original position. This code is used for follow-up care when the fracture is healing as expected without complications. The injury typically results from trauma and may affect ankle mobility, though the nondisplaced nature preserves joint stability. Routine healing indicates the fracture is progressing normally during subsequent medical encounters.

Causes

Direct trauma to the ankle, such as falls, sports injuries, or accidents, is the primary cause. High-impact forces or sudden twisting motions can lead to avulsion fractures, particularly in activities involving abrupt stops or changes in direction. The fracture occurs when a ligament or tendon pulls a small piece of bone away from the talus.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer) or activities with ankle injury risk.
• Osteoporosis or conditions weakening 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, confirm the fracture and evaluate healing progress. The diagnosis focuses on verifying the fracture’s nondisplaced status and routine healing during follow-up visits.

Treatment Options

Treatment typically includes immobilization with a cast or brace to support healing. Pain management with medications may be recommended. Physical therapy helps restore strength and mobility once the fracture shows signs of routine healing. Follow-up imaging monitors progress and ensures no complications arise.

Prognosis and Follow-Up

With proper care, nondisplaced avulsion fractures of the talus generally heal well. Routine healing indicates a favorable prognosis, but follow-up appointments are necessary to assess recovery. Most patients regain full function, though recovery time varies based on injury severity and adherence to treatment.

Complications

While rare, complications can include delayed healing, infection, or persistent pain. If the fracture does not heal as expected, further intervention may be required. Nerve or blood vessel damage is uncommon but possible with severe trauma.

Lifestyle & Prevention

Avoid high-impact activities until cleared by a healthcare provider. Wear supportive footwear and use protective gear during sports. Strengthening exercises for the ankle may reduce future injury risk. Maintain bone health through proper nutrition and exercise.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility declines. Contact a provider if signs of infection (e.g., redness, fever) appear or if the injury does not improve with treatment.

Tips for Medical Coders

Use this code for a nondisplaced avulsion fracture of the right talus during a subsequent encounter when the fracture is healing routinely. Document the fracture’s status (nondisplaced) and confirm routine healing to support code assignment. Ensure the encounter is for follow-up care, not initial treatment.
