Name of the Condition

• Nondisplaced fracture of the third metatarsal bone, unspecified foot. Also referred to as a closed fracture of the third metatarsal.

Summary

• This condition refers to a fracture of the third metatarsal bone in the foot that hasn't shifted out of place. It is classified as a closed fracture, meaning the skin around the fracture is not broken.

Causes

• The fracture is often caused by direct trauma to the foot, such as dropping a heavy object, or from stress over time due to repetitive activity like running or dancing.

Risk Factors

• Activities with high impact on feet, such as sports or dance.
• Osteoporosis or other bone-weakening conditions.
• Wearing inappropriate or unsupportive footwear.
• Advanced age can contribute due to decreased bone density.

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

• Physical examination by a healthcare professional.
• Imaging tests like X-rays to determine the exact nature and extent of the fracture.

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 function and strength.

Prognosis and Follow-Up

• With proper treatment, most nondisplaced fractures heal well within a few weeks to months.
• Regular follow-up with a healthcare provider to ensure proper healing and prevent complications.

Complications

• If untreated, the fracture could become displaced, which might require surgical intervention.
• Possible delayed healing or development of chronic pain.

Lifestyle & Prevention

• Wearing protective footwear during activities.
• Strengthening exercises for feet and legs.
• Adequate calcium and vitamin D intake for bone health.

When to Seek Professional Help

• Persistent or severe pain that inhibits daily activities.
• Swelling or bruising doesn't improve within a few days.
• Inability to bear weight or move the foot.

Tips for Medical Coders

• Ensure the fracture is coded as nondisplaced and closed to avoid errors.
• Use S92.336A for initial encounters specifically; check if a different code is needed for follow-up visits.
