S92.332A Displaced fracture of third metatarsal bone, left foot, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of third metatarsal bone, left foot, initial encounter for closed fracture.

Summary

This condition involves a break in the third metatarsal bone of the left foot where the bone fragments have shifted out of their normal alignment. It is classified as a closed fracture, meaning the skin over the fracture site remains intact. The term "initial encounter" indicates this is the first time the patient is receiving treatment for this specific injury.

Causes

The fracture is typically caused by direct trauma to the foot, such as a heavy object falling on it or a forceful impact during an accident. Twisting injuries or sudden, forceful movements can also result in a displaced metatarsal fracture. High-impact activities, like sports or falls, are common triggers.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer) or activities with sudden stops and turns.
• Wearing ill-fitting or non-supportive footwear that fails to absorb shock.
• Conditions that weaken bone density, such as osteoporosis or vitamin D deficiency.
• Advanced age, which may reduce bone strength and increase fall risk.
• Previous foot injuries that compromise bone integrity.

Symptoms

• Sharp pain in the midfoot, particularly over the third metatarsal area.
• Swelling, bruising, or discoloration around the affected bone.
• Difficulty bearing weight or walking on the left foot.
• Possible deformity if the fracture is severely displaced.

Diagnosis

A healthcare provider will perform a physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, are typically used to confirm the fracture and determine the extent of displacement. The closed nature of the fracture is confirmed by the absence of an open wound at the site.

Treatment Options

• Immobilization with a cast or walking boot to allow the bone to heal.
• Pain management using over-the-counter or prescription medications.
• Rest and elevation to reduce swelling.
• Physical therapy to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

Most displaced metatarsal fractures heal well with proper treatment, though recovery time may vary. Follow-up appointments are necessary to monitor healing and adjust treatment as needed. Return to normal activities is typically gradual, with weight-bearing restrictions initially.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized.
• Chronic pain or arthritis in the affected joint.
• Nerve damage or infection (rare, especially with closed fractures).
• Malunion, where the bone heals in a misaligned position.

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities.
• Gradually increase activity intensity to avoid overuse injuries.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Use protective gear during high-impact sports.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, pus, fever) after an injury to the left foot.

Tips for Medical Coders

Document the specific location (left foot), displacement status, and encounter type (initial for closed fracture) to ensure accurate coding. Include details about the fracture's alignment and whether the skin is intact to support the closed fracture classification.
