S92.351B Displaced fracture of fifth metatarsal bone, right foot, initial encounter for open fracture

Name of the Condition

• Technical Term: Displaced fracture of fifth metatarsal bone, right foot, initial encounter for open fracture
• ICD-10 Code: S92.351B
• Common Name: Broken fifth metatarsal (right foot, open fracture)

Summary

A displaced fracture of the fifth metatarsal bone in the right foot is a break where the bone fragments are out of alignment, and the fracture is open (exposing the bone to the external environment). This injury typically results from trauma and requires prompt medical attention due to the risk of infection and further complications.

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 broken bone pierces the skin, often due to significant force or a sharp object.

Risk Factors

• Participation in high-impact sports or activities with foot trauma risk
• Wearing inadequate or non-protective footwear
• Conditions that weaken bones (e.g., osteoporosis)
• Advanced age, which may reduce bone density and balance
• Previous foot injuries or fractures

Symptoms

• Severe pain and tenderness on the outer edge of the right foot
• Visible wound or open skin near the fracture site
• Swelling, bruising, or bleeding at the affected area
• Difficulty bearing weight or walking
• Possible deformity due to bone displacement

Diagnosis

A healthcare provider will conduct a physical examination to assess pain, swelling, and wound characteristics. Imaging tests, such as X-rays, are used to confirm the fracture, displacement, and open nature. Additional evaluations may include assessing for infection or nerve damage.

Treatment Options

• Immediate wound care and cleaning to reduce infection risk
• Surgical intervention to realign and stabilize the bone (e.g., internal fixation)
• Antibiotics to prevent or treat infection
• Immobilization with a cast or splint to support healing
• Follow-up care to monitor for complications

Prognosis and Follow-Up

Recovery depends on fracture severity, treatment, and adherence to care plans. Most patients heal with proper management, but open fractures carry a higher risk of infection or delayed healing. Regular follow-up appointments are necessary to assess progress and adjust treatment.

Complications

• Infection at the wound site
• Delayed or nonunion of the fracture
• Nerve or blood vessel damage
• Chronic pain or arthritis in the foot
• Difficulty returning to normal activities

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities
• Use protective gear (e.g., shin guards) in high-risk sports
• Maintain bone health through diet and exercise
• Avoid activities that increase foot trauma risk
• Seek prompt care for foot injuries to prevent complications

When to Seek Professional Help

• Severe pain, swelling, or bleeding after a foot injury
• Visible bone or open wound
• Inability to bear weight on the foot
• Signs of infection (e.g., redness, pus, fever)
• Persistent pain or deformity after initial treatment

Tips for Medical Coders

Document the fracture as displaced, specify the right foot, and note the open nature and initial encounter. Include details on wound characteristics, treatment provided, and any associated complications to ensure accurate coding.
