S92.321A Displaced fracture of second metatarsal bone, right foot, initial encounter for closed fracture

Name of the Condition

• Technical Term: Displaced fracture of second metatarsal bone, right foot, initial encounter for closed fracture
• ICD-10 Code: S92.321A
• Common Name: Broken second metatarsal (right foot)

Summary

A displaced fracture of the second metatarsal bone in the right foot is a break in the long bone connecting the ankle to the toes, where the bone fragments are out of alignment. This injury occurs during the initial encounter for a closed fracture, meaning the skin is intact and no surgical intervention has been performed yet. The second metatarsal is a weight-bearing bone, and displacement may affect mobility and healing.

Causes

Direct trauma to the right foot, such as a fall, sports injury, or heavy object impact, is the primary cause. Twisting forces or repetitive stress from activities like running may also lead to this type of fracture. The displacement occurs when the bone breaks and shifts out of its normal position.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer)
• Wearing improper or non-supportive footwear
• Conditions that weaken bones, such as osteoporosis
• Advanced age, which may reduce bone density and balance
• Previous foot injuries or fractures

Symptoms

• Pain and tenderness in the midfoot (right foot)
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the right foot
• Visible deformity or misalignment of the foot
• Possible numbness or tingling if nerves are affected

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, evaluate displacement, and rule out other injuries. The documentation must specify the right foot, second metatarsal, and closed fracture status.

Treatment Options

Treatment depends on the severity of displacement. Non-surgical options include immobilization with a cast or boot, pain management, and rest. Surgical intervention may be required for severe displacement to realign the bone. Physical therapy is often recommended during recovery to restore strength and mobility.

Prognosis and Follow-Up

Most displaced fractures heal with proper treatment, but recovery time varies. Follow-up appointments are necessary to monitor healing, typically with repeat imaging. Full weight-bearing may be delayed until the bone is stable, and physical therapy may be needed to regain function.

Complications

• Delayed healing or nonunion
• Arthritis in the affected joint
• Chronic pain or stiffness
• Nerve damage leading to numbness
• Infection (rare, but possible with surgical intervention)

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities.
• Avoid high-impact sports without proper conditioning.
• Maintain bone health through diet and exercise.
• Use protective gear (e.g., orthotics) if at risk for foot injuries.

When to Seek Professional Help

Seek immediate care if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, fever). Persistent pain or swelling after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the right foot, second metatarsal, displaced status, and initial encounter for a closed fracture. Ensure the encounter type (initial) and fracture type (closed) are clearly specified. Code S92.321A requires confirmation of displacement and no prior treatment.
