S92.336 Nondisplaced fracture of third metatarsal bone, unspecified foot

Name of the Condition

• Nondisplaced fracture of third metatarsal bone, unspecified foot.

Summary

This condition involves a break in the third metatarsal bone of the foot where the bone fragments remain in their normal alignment. It is classified as a nondisplaced fracture, meaning the bone has not shifted out of place. The term "unspecified foot" indicates the documentation does not specify whether the injury is in the left or right foot.

Causes

The fracture is typically caused by direct trauma to the foot, such as a heavy object falling or a twisting injury. 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, swelling, or tenderness in the midfoot region
• Difficulty bearing weight or walking on the affected foot
• Bruising or discoloration around the area

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 extent.

Treatment Options

• Rest and immobilization, often using a cast or walking boot, to allow healing
• Over-the-counter pain relievers such as acetaminophen or ibuprofen to manage pain
• Physical therapy might be recommended after the bone has healed to restore strength and mobility

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper treatment and rest. 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's health and activity level.

Complications

• Delayed healing or nonunion if the fracture does not heal properly
• Chronic pain or stiffness in the foot
• Post-traumatic arthritis in the affected joint
• Nerve or tissue damage in severe cases

Lifestyle & Prevention

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

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) around the injury.

Tips for Medical Coders

When coding for S92.336, ensure the documentation specifies a nondisplaced fracture of the third metatarsal bone without indicating displacement or a specific foot (left/right). Verify that the fracture is not associated with an open wound or other complicating factors, as these would require different coding. Document the encounter type (e.g., initial, subsequent) if applicable for accurate reporting.
