S92.325A Nondisplaced fracture of second metatarsal bone, left foot, initial encounter for closed fracture

Name of the Condition

• Technical Term: Nondisplaced fracture of second metatarsal bone, left foot, initial encounter for closed fracture
• ICD-10 Code: S92.325A
• Common Name: Broken second metatarsal (left foot)

Summary

A nondisplaced fracture of the second metatarsal bone in the left foot is a break in the long bone connecting the ankle to the toes, where the bone fragments remain aligned. This injury typically results from trauma, such as a direct impact or twisting force, and is classified as closed (no skin penetration) during the initial encounter. The second metatarsal is a weight-bearing bone, making it susceptible to injury during activities that stress the foot. Treatment focuses on immobilization and pain management, with healing dependent on the fracture's stability and adherence to care plans.

Causes

Direct trauma to the left foot, such as a fall, sports injury, or dropping a heavy object, is the most common cause. Repetitive stress from activities like running or jumping can also lead to stress fractures over time. Twisting the foot or sudden impact may result in a fracture, particularly in high-impact scenarios.

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 area of the left foot
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the injured foot
• Possible deformity if the fracture is severe (though nondisplaced fractures typically maintain alignment)

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and mobility. Imaging, such as X-rays, confirms the fracture and verifies that it is nondisplaced and closed. Additional tests may be ordered if soft tissue damage or other injuries are suspected.

Treatment Options

Treatment typically includes immobilization with a cast or boot to stabilize the bone, pain management with medications, and activity modification to avoid weight-bearing. Follow-up imaging may be used to monitor healing. Severe cases may require surgical intervention, though nondisplaced fractures often heal with conservative care.

Prognosis and Follow-Up

Prognosis is generally favorable for nondisplaced fractures, with most patients recovering fully within 6–8 weeks. Follow-up appointments ensure proper healing and may involve gradual weight-bearing exercises. Complications are rare but can include delayed union or nonunion if the fracture does not heal as expected.

Complications

• Delayed or incomplete healing (nonunion)
• Chronic pain or stiffness
• Post-traumatic arthritis in the midfoot
• Nerve or soft tissue damage (rare)

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities.
• Gradually increase physical activity to avoid overuse injuries.
• Maintain bone health through adequate calcium and vitamin D intake.
• Use protective gear during high-impact sports.

When to Seek Professional Help

Seek immediate care if pain worsens, swelling increases, or mobility is severely limited. Contact a healthcare provider if symptoms persist beyond expected healing timelines or if new symptoms (e.g., numbness, discoloration) develop.

Tips for Medical Coders

Document the fracture as nondisplaced and closed, with specification of the left foot and initial encounter. Include details on trauma mechanism, imaging results, and treatment plans to support code accuracy. Ensure alignment with clinical notes to reflect the absence of displacement and skin penetration.
