S92.344B Nondisplaced fracture of fourth metatarsal bone, right foot, initial encounter for open fracture

Name of the Condition

• Nondisplaced fracture of fourth metatarsal bone, right foot, initial encounter for open fracture
• ICD-10 code: S92.344B

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 is classified as an open fracture, meaning the skin is broken, and it is the initial encounter for treatment. Open fractures require prompt evaluation to assess soft tissue damage and prevent infection.

Causes

Direct trauma to the right foot, such as a fall, crush injury, or penetrating wound, is the primary cause. Open fractures may result from high-energy impacts or injuries that break the skin and underlying bone simultaneously. Repetitive stress or minor trauma in individuals with weakened bones can also lead to open fractures in some cases.

Risk Factors

• Participation in activities with a high risk of foot injury (e.g., sports, construction work)
• Wearing inadequate or non-protective footwear
• Conditions that impair bone strength (e.g., osteoporosis, diabetes)
• Advanced age, which may reduce bone density and balance
• Previous foot injuries or surgeries

Symptoms

• Severe pain localized to the right midfoot
• Visible wound or break in the skin over the fracture site
• Swelling, bruising, or bleeding at the injury
• Difficulty bearing weight on the right foot
• Possible exposure of bone fragments through the skin

Diagnosis

A healthcare provider will conduct a physical examination to assess the wound, pain, and range of motion. Imaging tests, such as X-rays, are used to confirm the fracture and verify that it is nondisplaced. Additional evaluations may include assessing soft tissue damage and checking for signs of infection.

Treatment Options

Treatment focuses on cleaning the wound, preventing infection, and stabilizing the fracture. This may involve wound care, antibiotics, and immobilization with a cast or brace. Surgical intervention may be necessary if the fracture is unstable or if there is significant soft tissue damage. Pain management and follow-up care are also essential.

Prognosis and Follow-Up

With proper treatment, most nondisplaced open fractures heal without complications. Follow-up appointments are necessary to monitor healing, remove hardware if used, and assess for infection. Full recovery may take several weeks to months, depending on the severity of the injury and adherence to treatment.

Complications

• Infection at the fracture site or wound
• Delayed healing or nonunion
• Chronic pain or stiffness
• Nerve or blood vessel damage
• Post-traumatic arthritis in the foot

Lifestyle & Prevention

• Wear protective footwear during high-risk activities
• Maintain bone health through a balanced diet and regular exercise
• Avoid repetitive high-impact activities that stress the feet
• Address underlying conditions that weaken bones (e.g., osteoporosis)
• Seek prompt care for foot injuries to prevent complications

When to Seek Professional Help

Seek immediate medical attention if you experience a foot injury with an open wound, severe pain, or inability to bear weight. Signs of infection, such as increasing redness, swelling, or pus, also require urgent evaluation.

Tips for Medical Coders

Document the fracture as nondisplaced, the right foot, and the initial encounter for an open fracture. Include details about the wound (e.g., size, contamination) and any associated injuries. Ensure the code S92.344B is used for the initial encounter; subsequent encounters for healing or complications may require different codes.
