S92.342D Displaced fracture of fourth metatarsal bone, left foot, subsequent encounter for fracture with routine healing

Name of the Condition

• Displaced fracture of fourth metatarsal bone, left foot, subsequent encounter for fracture with routine healing
• ICD-10 code: S92.342D

Summary

A displaced fracture of the fourth metatarsal bone in the left 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. The term "subsequent encounter for fracture with routine healing" indicates this is a follow-up visit during the healing phase, where the fracture is progressing normally without complications.

Causes

Direct trauma to the left foot, such as a fall, impact during sports, or a heavy object dropped on the foot, is the primary cause. Repetitive stress from activities like running or jumping can also lead to fractures over time.

Risk Factors

• Participation in high-impact sports (e.g., soccer, basketball)
• 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 and tenderness localized to the outer midfoot
• Swelling and bruising around the affected area
• Difficulty bearing weight or walking on the left foot
• Possible visible 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 evaluate alignment. During a subsequent encounter, imaging may show signs of routine healing, such as callus formation or reduced displacement.

Treatment Options

Treatment depends on the severity of the fracture. Conservative management includes rest, ice, compression, and elevation (RICE), along with immobilization using a cast or walking boot. Pain relief may involve over-the-counter or prescription medications. Physical therapy can help restore strength and mobility once healing progresses.

Prognosis and Follow-Up

With proper treatment and routine healing, most displaced metatarsal fractures heal within 6–8 weeks. Follow-up visits are important to monitor progress and adjust care as needed. Full recovery may take several months, depending on the extent of the injury and adherence to treatment.

Complications

Potential complications include nonunion (failure to heal), malunion (improper healing), chronic pain, or arthritis in the affected joint. Infection may occur if the fracture was open, though this is less common in subsequent encounters with routine healing.

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities.
• Gradually increase physical activity to avoid overuse injuries.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Use protective gear during high-impact sports.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or new symptoms (e.g., numbness, discoloration) develop. These may indicate complications or improper healing.

Tips for Medical Coders

Use S92.342D for a displaced fracture of the fourth metatarsal bone in the left foot during a subsequent encounter when the fracture is healing routinely. Document the encounter type (subsequent) and confirm routine healing through clinical notes or imaging. Ensure the laterality (left foot) and displacement are clearly documented to support code assignment.
