S92.333B Displaced fracture of third metatarsal bone, unspecified foot, initial encounter for open fracture

Name of the Condition

• Displaced fracture of third metatarsal bone, unspecified foot, initial encounter for open fracture.

Summary

A displaced fracture of the third metatarsal bone in the unspecified foot is a break in the long bone connecting the ankle to the toes, where the bone fragments have shifted out of their normal alignment. This injury is classified as an open fracture, meaning the bone has pierced the skin, and it is the initial encounter for treatment. Open fractures require prompt medical attention to reduce infection risk and stabilize the bone.

Causes

Direct trauma to the foot, such as a fall, crush injury, or high-impact event, is the primary cause. Open fractures occur when the force of the injury is severe enough to break the skin, exposing the bone. Repetitive stress or underlying bone weakness may also contribute to fracture risk.

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

• Severe pain, swelling, or tenderness in the midfoot area
• Visible bone protrusion or open wound at the fracture site
• Difficulty bearing weight or walking on the affected foot
• Bruising, discoloration, or bleeding around the injury
• 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. Additional tests may be ordered to evaluate for infection or soft tissue damage due to the open nature of the injury.

Treatment Options

• Immediate wound care to clean and dress the open fracture to prevent infection
• Surgical intervention to realign and stabilize the bone, often using pins, screws, or plates
• Antibiotics to reduce infection risk
• Immobilization with a cast or external fixator to allow healing
• Pain management with medications as needed

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of treatment, and the absence of complications. Most patients recover fully with proper care, though recovery may take several weeks to months. Follow-up appointments are necessary to monitor healing and adjust treatment as needed.

Complications

• Infection at the fracture site
• Delayed healing or nonunion of the bone
• Nerve or blood vessel damage
• Chronic pain or arthritis in the foot
• Long-term mobility issues

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities
• Use protective gear in high-impact sports
• Maintain bone health through a balanced diet and regular exercise
• Avoid activities that increase fall or injury risk

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 increased redness, pus, or fever, also require prompt evaluation.

Tips for Medical Coders

Document the specific foot (unspecified), the displaced nature of the fracture, and the open wound status. Ensure the initial encounter for treatment is clearly noted, as this impacts code assignment. Verify that all clinical details align with the code’s definition to support accurate reporting.
