S92.335A Nondisplaced fracture of third metatarsal bone, left foot, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of third metatarsal bone, left foot, initial encounter for closed fracture.

Summary

A nondisplaced fracture of the third metatarsal bone in the left foot is a break in the long bone connecting the ankle to the toes, where the bone fragments remain in their normal alignment. This injury typically results from trauma or stress and is classified as closed (skin intact) during the initial encounter. Medical evaluation is necessary to confirm the fracture and guide treatment.

Causes

Direct trauma to the left foot, such as a fall, sports injury, or dropping a heavy object, is a common cause. Repetitive stress from activities like running or jumping can 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
• Previous foot injuries or fractures

Symptoms

• Pain and tenderness in the midfoot area of the left foot
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the left foot
• Possible mild deformity if the fracture is displaced (though nondisplaced fractures typically lack visible deformity)

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 if it is nondisplaced. Additional imaging may be ordered if a stress fracture is suspected.

Treatment Options

• Rest and immobilization, often using a cast or walking boot, to allow healing
• Over-the-counter pain relievers to manage discomfort
• Physical therapy to restore strength and mobility once healing progresses
• Follow-up imaging to ensure proper alignment during recovery

Prognosis and Follow-Up

Most nondisplaced fractures of the third metatarsal bone heal well with conservative treatment. Full recovery typically occurs within 6–8 weeks, though activity restrictions may be necessary during this period. Follow-up appointments are important to monitor healing and adjust treatment as needed.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized
• Chronic pain or stiffness in the foot
• Risk of future fractures due to weakened bone
• Rarely, infection if the fracture becomes open (though this code specifies a closed fracture)

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during daily activities and sports
• 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 to reduce trauma risk

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, inability to bear weight, or visible deformity in the left foot. Also, consult a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

This code (S92.335A) is specific to a nondisplaced fracture of the third metatarsal bone in the left foot during the initial encounter for a closed fracture. Documentation should clearly indicate the bone involved, laterality (left foot), displacement status (nondisplaced), and encounter type (initial for closed fracture) to support accurate coding. Ensure alignment with clinical notes and imaging reports.
