S92.355D Nondisplaced fracture of fifth metatarsal bone, left foot, subsequent encounter for fracture with routine healing

Name of the Condition

• Technical Term: Nondisplaced fracture of fifth metatarsal bone, left foot, subsequent encounter for fracture with routine healing
• Common Name: Broken fifth metatarsal (left foot), follow-up for healing

Summary

A nondisplaced fracture of the fifth metatarsal bone in the left foot is a break in the long bone on the outer edge of the foot that remains in its normal alignment. This code specifies a subsequent encounter, indicating the patient is being seen for follow-up during the healing phase, with routine healing expected. Medical evaluation is typically ongoing to monitor progress and guide care.

Causes

Direct trauma to the foot, such as a fall, twist, or impact, is the primary cause. Repetitive stress from activities like running or jumping can also lead to fractures over time. The subsequent encounter phase reflects the ongoing management of the injury as it heals.

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

• Pain and tenderness on the outer edge of the left foot (may be reduced from initial injury)
• Swelling or bruising in the affected area (gradually improving)
• Difficulty bearing weight on the left foot (improving with healing)

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’s alignment and monitor healing progress during follow-up visits.

Treatment Options

• Continued rest and reduced activity to support healing
• Immobilization (e.g., cast or boot) if needed to maintain alignment
• Physical therapy to restore strength and mobility as healing allows
• Pain management with medications or other modalities

Prognosis and Follow-Up

Most nondisplaced fractures of the fifth metatarsal heal well with proper care. Follow-up appointments are important to ensure healing is progressing as expected. Full recovery time varies but often ranges from several weeks to a few months, depending on the individual and injury severity.

Complications

• Delayed healing or nonunion (rare)
• Persistent pain or stiffness
• Re-fracture if activity is resumed too soon
• Chronic instability in the foot

Lifestyle & Prevention

• Wear supportive footwear appropriate for activities
• Gradually increase activity levels to avoid overuse
• Maintain bone health through proper nutrition (e.g., calcium, vitamin D)
• Use proper techniques during sports or exercise to reduce injury risk

When to Seek Professional Help

• Increasing pain, swelling, or bruising
• Inability to bear weight on the foot
• Signs of infection (e.g., redness, warmth, fever)
• New deformity or instability in the foot

Tips for Medical Coders

This code (S92.355D) is used for a subsequent encounter for a nondisplaced fracture of the fifth metatarsal bone in the left foot with routine healing. Documentation should specify the fracture’s alignment, the left foot, and that the encounter is for follow-up during the healing phase. Ensure the record reflects routine healing progress to support this code.
