S92.355A Nondisplaced fracture of fifth metatarsal bone, left foot, initial encounter for closed fracture

Name of the Condition

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

Summary

A nondisplaced fracture of the fifth metatarsal bone in the left foot is a break where the bone fragments remain in their normal alignment. 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 condition typically results from trauma or overuse and requires evaluation to confirm the fracture and guide treatment.

Causes

Direct trauma to the foot, such as a fall, twist, or impact, is the most common cause. Repetitive stress from activities like running or jumping may also lead to stress 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 left foot
• Swelling or bruising in the affected area
• Difficulty bearing weight or walking
• Possible mild deformity if the fracture is displaced (though nondisplaced fractures typically maintain alignment)

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 determine its alignment. Additional imaging may be ordered if a more complex injury is suspected.

Treatment Options

• Rest and reduced activity to promote healing
• Immobilization using a cast or boot to keep the bone aligned
• Pain management with over-the-counter or prescription medications
• Physical therapy to restore strength and mobility after initial healing

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper treatment. Follow-up appointments are typically scheduled to monitor healing progress, often with repeat imaging to confirm bone alignment. Full recovery may take several weeks to months, depending on the individual and activity level.

Complications

• Delayed healing or nonunion if the fracture does not heal properly
• Malunion, where the bone heals in an abnormal position
• Chronic pain or stiffness in the foot
• Increased risk of future fractures in the same area

Lifestyle & Prevention

• Wear supportive footwear appropriate for activities
• Gradually increase activity intensity to avoid overuse injuries
• Maintain bone health through a balanced diet rich in calcium and vitamin D
• Use proper techniques and protective gear during sports or high-impact activities

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, visible deformity, or signs of infection (e.g., redness, warmth, or pus) at the injury site.

Tips for Medical Coders

Document the location (left foot), fracture type (nondisplaced), encounter type (initial), and whether the fracture is open or closed (closed in this case). Ensure the record includes details supporting the diagnosis, such as imaging results or clinical findings, to justify the code assignment.
