S92.334B Nondisplaced fracture of third metatarsal bone, right foot, initial encounter for open fracture

Name of the Condition

• Nondisplaced fracture of third metatarsal bone, right foot, initial encounter for open fracture.

Summary

A nondisplaced fracture of the third metatarsal bone in the right foot is a break in the long bone connecting the ankle to the toes, 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 medical attention to reduce infection risk and promote healing.

Causes

Direct trauma to the right foot, such as a crush injury, fall, or penetrating wound, is the primary cause. High-energy impacts or accidents that break the skin and fracture the bone are common scenarios. Repetitive stress or minor trauma may also lead to open fractures if the skin is compromised.

Risk Factors

• Participation in activities with high foot trauma risk (e.g., contact sports, construction work)
• Wearing inadequate or non-protective footwear
• Conditions that weaken bones (e.g., osteoporosis, diabetes)
• Advanced age, which may reduce bone density and skin integrity
• Previous foot injuries or surgeries

Symptoms

• Severe pain, swelling, and tenderness in the midfoot
• Visible wound or break in the skin over the fracture site
• Difficulty bearing weight or walking
• Possible bleeding or drainage from the open wound
• Bruising or discoloration around the affected area

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 it is nondisplaced. The open nature of the fracture is documented, and additional tests (e.g., CT scans) may be ordered to evaluate soft tissue damage.

Treatment Options

• Immediate wound care to clean and dress the open fracture
• Antibiotics to prevent infection
• Immobilization with a cast, splint, or external fixator
• Pain management with medications
• Surgical intervention if the fracture is unstable or requires debridement
• Follow-up care to monitor healing and wound closure

Prognosis and Follow-Up

With proper treatment, most nondisplaced open fractures heal within 6–8 weeks. Follow-up appointments are essential to assess healing, remove hardware if used, and monitor for infection. Physical therapy may be recommended to restore strength and mobility.

Complications

• Infection at the fracture site or wound
• Delayed healing or nonunion
• Nerve or blood vessel damage
• Chronic pain or arthritis
• Skin necrosis or tissue loss

Lifestyle & Prevention

• Wear protective footwear during high-risk activities
• Maintain bone health with a balanced diet and exercise
• Avoid repetitive high-impact stress on the feet
• Promptly treat minor foot injuries to prevent worsening
• Practice good foot hygiene to reduce infection 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 (e.g., redness, pus, fever) also require urgent care.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the right foot and open nature. Include details of the initial encounter, such as wound characteristics and treatment provided. Ensure the open fracture is clearly differentiated from closed fractures for accurate coding.
