S92.034A Nondisplaced avulsion fracture of tuberosity of right calcaneus, initial encounter for closed fracture

Name of the Condition

• Nondisplaced avulsion fracture of tuberosity of right calcaneus, initial encounter for closed fracture

Summary

This condition involves a fracture where a small piece of bone is pulled away from the tuberosity of the right calcaneus (heel bone) due to tendon or ligament tension. The fracture is nondisplaced, meaning the bone fragment remains in its original position. It typically results from trauma and can affect mobility and weight-bearing ability, with severity depending on the size of the avulsed fragment.

Causes

High-impact trauma, such as falls or direct force to the heel. Sudden, forceful muscle contractions (e.g., during sports or physical activity) that pull on the attached tendon or ligament.

Risk Factors

• Engaging in high-impact activities or sports.
• Osteoporosis or other bone-weakening conditions.
• Improper footwear or uneven surfaces that increase fall risk.

Symptoms

• Sudden, localized pain at the heel or back of the foot.
• Swelling, bruising, or tenderness around the affected area.
• Difficulty or inability to bear weight on the foot.
• Possible visible lump or deformity if the fragment is displaced.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays or CT scans, to confirm the fracture and evaluate the size and displacement of the avulsed fragment.

Treatment Options

• Rest and immobilization with a cast or splint to allow healing.
• Pain management with medications or ice therapy.
• Surgical intervention may be required if the fragment is large or unstable.

Prognosis and Follow-Up

Most nondisplaced avulsion fractures heal with conservative treatment. Follow-up imaging may be used to monitor healing progress. Physical therapy is often recommended to restore strength and mobility.

Complications

• Delayed healing or nonunion.
• Chronic pain or instability.
• Infection (rare, especially with surgical intervention).

Lifestyle & Prevention

• Wear supportive footwear during physical activity.
• Avoid uneven surfaces to reduce fall risk.
• Strengthen lower leg muscles to improve stability.

When to Seek Professional Help

Seek immediate care for severe pain, inability to bear weight, or visible deformity. Persistent pain or swelling after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the right calcaneus. Note the initial encounter for a closed fracture. Include details on trauma mechanism, imaging results, and treatment plan to support code accuracy.
