S92.344 Nondisplaced fracture of fourth metatarsal bone, right foot

Name of the Condition

• Nondisplaced fracture of fourth metatarsal bone, right foot
• ICD-10 code: S92.344

Summary

A nondisplaced fracture of the fourth metatarsal bone in the right foot is a break in the long bone of the forefoot where the bone fragments remain in their normal alignment. This injury typically results from trauma or repetitive stress and may vary in severity, depending on the force of impact and the integrity of the surrounding tissues.

Causes

Direct trauma to the foot, such as a fall, impact during sports, or a heavy object dropped on the foot, is a common cause. Stress fractures may also occur from overuse, particularly in activities involving repetitive weight-bearing or sudden increases in physical activity.

Risk Factors

• Participation in high-impact sports (e.g., running, 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 localized to the outer midfoot area of the right foot
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the right foot
• Possible mild tenderness without visible deformity

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 evaluate alignment. Additional imaging may be considered if clinical suspicion is high despite initial negative results.

Treatment Options

Treatment may include rest, ice, compression, and elevation (RICE) to reduce swelling. Immobilization with a cast, boot, or stiff-soled shoe is often recommended to protect the bone during healing. Pain management with over-the-counter medications may be advised. Physical therapy may be prescribed to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

Most nondisplaced fractures of the fourth metatarsal bone heal well with conservative management. Recovery typically takes 4–6 weeks, depending on the individual and the extent of the injury. Follow-up appointments are important to monitor healing and adjust treatment as needed. Return to normal activities is usually gradual, guided by pain tolerance and functional improvement.

Complications

While uncommon, potential complications include delayed healing, nonunion, or malunion if the fracture is not properly managed. Infection may occur if there is an open wound. Chronic pain or stiffness in the foot may persist in some cases, particularly with inadequate rehabilitation.

Lifestyle & Prevention

Wearing supportive, properly fitting footwear during activities can reduce the risk of injury. Gradually increasing the intensity of physical activity and incorporating strength and balance training may help prevent overuse injuries. Avoiding repetitive high-impact movements on hard surfaces and maintaining bone health through adequate nutrition (e.g., calcium, vitamin D) are also beneficial.

When to Seek Professional Help

Seek medical attention if pain is severe, worsens, or does not improve with rest. Immediate care is needed if there is an open wound, visible deformity, or inability to bear weight on the right foot. Persistent swelling, bruising, or signs of infection (e.g., redness, warmth, fever) should also prompt evaluation.

Tips for Medical Coders

Document the specific location (right foot) and fracture type (nondisplaced) to ensure accurate coding. Include details about the mechanism of injury, clinical findings, and any imaging results that confirm the diagnosis. Ensure the documentation supports the use of S92.344 and aligns with the clinical presentation of a nondisplaced fracture of the fourth metatarsal bone in the right foot.
