S92.031B Displaced avulsion fracture of tuberosity of right calcaneus, initial encounter for open fracture

Name of the Condition

• Displaced avulsion fracture of tuberosity of right calcaneus, initial encounter for open fracture

Summary

This condition involves a fracture where a fragment of bone is pulled away from the tuberosity of the right calcaneus (heel bone) due to tendon or ligament tension, with the fracture site open to the external environment. It typically results from trauma and can affect mobility and weight-bearing ability, with severity depending on the size of the avulsed fragment and the extent of soft tissue damage.

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, leading to an open fracture.

Risk Factors

• Engaging in high-impact activities or sports.
• Osteoporosis or other bone-weakening conditions.
• Improper footwear or uneven surfaces that increase fall risk.
• Open wounds or lacerations near the heel that expose the fracture site.

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.
• Visible open wound or laceration at the fracture site.
• Possible deformity if the fragment is displaced.

Diagnosis

Physical examination to assess pain, swelling, and range of motion, with attention to open wounds. Imaging tests, such as X-rays or CT scans, to confirm the fracture, evaluate the size and displacement of the avulsed fragment, and assess soft tissue damage. Documentation of the open fracture is critical for coding.

Treatment Options

• Immediate wound care to clean and dress the open fracture site.
• Antibiotics to prevent infection.
• Rest and immobilization with a cast or splint to allow healing.
• Pain management with medications or ice therapy.
• Surgical intervention for severe or displaced fractures to realign the bone and repair soft tissue.

Prognosis and Follow-Up

Healing time varies, typically 6–12 weeks, depending on fracture severity and infection risk. Follow-up appointments monitor for infection, proper healing, and functional recovery. Physical therapy may be recommended to restore mobility and strength.

Complications

• Infection at the open fracture site.
• Delayed healing or nonunion.
• Chronic pain or arthritis.
• Nerve or blood vessel damage.
• Long-term mobility issues or deformity.

Lifestyle & Prevention

• Wear appropriate footwear with good support during high-impact activities.
• Avoid uneven surfaces or hazardous environments that increase fall risk.
• Strengthen foot and ankle muscles through targeted exercises.
• Seek prompt medical care for open wounds near the heel to reduce infection risk.

When to Seek Professional Help

• Sudden, severe pain in the heel or foot after trauma.
• Visible open wound or laceration at the heel.
• Inability to bear weight or significant swelling/bruising.
• Signs of infection, such as redness, warmth, or pus at the wound site.

Tips for Medical Coders

Document the specific location (right calcaneus), the nature of the fracture (displaced avulsion), and the encounter type (initial for open fracture). Ensure the open fracture is clearly described to support the code. Note any associated soft tissue damage or wound characteristics for accurate coding.
