S92.351A Displaced fracture of fifth metatarsal bone, right foot, initial encounter for closed fracture

Name of the Condition

• Technical Term: Displaced fracture of fifth metatarsal bone, right foot, initial encounter for closed fracture
• Common Name: Broken fifth metatarsal (right foot)

Summary

A displaced fracture of the fifth metatarsal bone in the right foot is a break where the bone fragments are not aligned. This is an initial encounter for a closed fracture, meaning the skin is intact and the injury is being addressed for the first time. The fifth metatarsal is the long bone on the outer edge of the foot, and displacement can affect stability and healing.

Causes

Direct trauma to the foot, such as a fall, twist, or impact, is the primary cause. Sports injuries, missteps, or accidents involving the foot are common triggers. Repetitive stress from activities like running or jumping may also lead to fractures over time.

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 right foot
• Swelling or bruising in the affected area
• Difficulty bearing weight on the foot
• 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, assess displacement, and rule out other injuries.

Treatment Options

• Immobilization using a cast, boot, or splint to keep the bone aligned
• Rest and reduced activity to promote healing
• Pain management with medications or ice
• Physical therapy to restore strength and mobility after initial healing
• Surgical intervention if the fracture is severely displaced or unstable

Prognosis and Follow-Up

Most displaced fractures heal with proper treatment, but recovery time varies. Follow-up appointments are necessary to monitor healing, often with repeat imaging. Complications like nonunion or malunion may require additional intervention.

Complications

• Nonunion (failure to heal)
• Malunion (healing in an incorrect position)
• Chronic pain or arthritis
• Nerve or tissue damage from the injury or treatment

Lifestyle & Prevention

• Wear supportive footwear appropriate for activities
• Gradually increase activity intensity to avoid overuse
• Maintain bone health with proper nutrition (e.g., calcium, vitamin D)
• Use protective gear during high-risk activities

When to Seek Professional Help

Seek immediate care if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, fever). Persistent pain or swelling after initial treatment also warrants evaluation.

Tips for Medical Coders

Document the laterality (right foot), displacement status, and encounter type (initial for closed fracture) to support the code S92.351A. Ensure clinical notes specify the fracture as displaced and the encounter as initial for a closed fracture to meet coding guidelines.
