S92.355 Nondisplaced fracture of fifth metatarsal bone, left foot

Name of the Condition

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

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 injury typically results from trauma or repetitive stress and requires medical evaluation to confirm the fracture and guide treatment.

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.

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 on the left foot

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.

Treatment Options

• Rest and reduced activity to promote healing
• Immobilization using a cast or boot to keep the bone aligned
• Physical therapy to restore strength and mobility after initial healing

Prognosis and Follow-Up

Most nondisplaced fractures of the fifth metatarsal heal well with proper treatment. Follow-up care may include monitoring for healing progress and gradual return to activity. Complications are rare but may include delayed healing or nonunion if the fracture does not heal properly.

Complications

• Delayed healing or nonunion
• Chronic pain
• Arthritis in the affected joint

Lifestyle & Prevention

• Wear supportive footwear during physical activities
• Avoid sudden increases in activity intensity
• Maintain bone health through proper nutrition and exercise

When to Seek Professional Help

Seek medical attention if you experience severe pain, swelling, or difficulty bearing weight after an injury to the foot. Prompt evaluation is important to confirm the diagnosis and initiate appropriate treatment.

Tips for Medical Coders

When coding for S92.355, ensure documentation specifies the nondisplaced nature of the fracture and the left foot involvement. Verify that the fracture is not associated with a sequela or other complicating factors to avoid miscoding.
