S92.324A Nondisplaced fracture of second metatarsal bone, right foot, initial encounter for closed fracture

Name of the Condition

• Technical Term: Nondisplaced fracture of second metatarsal bone, right foot, initial encounter for closed fracture
• ICD-10 Code: S92.324A
• Common Name: Broken second metatarsal (right foot), closed, initial encounter

Summary

A nondisplaced fracture of the second metatarsal bone in the right foot is a break in the long bone of the midfoot where the bone fragments remain aligned. This injury typically results from trauma, such as a direct impact or twisting force, and is classified as closed (no skin penetration) during the initial encounter. The second metatarsal is a weight-bearing bone, making it susceptible to injury during activities that stress the foot. Treatment and recovery depend on the stability of the fracture and the absence of displacement.

Causes

Direct trauma to the right foot, such as a fall, sports injury, or dropping a heavy object, is the most common cause. Repetitive stress from activities like running or jumping can also lead to stress fractures over time. Twisting the foot or sudden impact may result in a nondisplaced fracture, particularly in high-impact scenarios.

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 in the midfoot area of the right foot
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the injured foot
• Possible mild deformity if the fracture is severe

Diagnosis

Diagnosis typically involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays, are used to confirm the fracture and verify that it is nondisplaced and closed. Additional tests, like CT scans or MRIs, may be ordered if soft tissue damage or other injuries are suspected.

Treatment Options

Treatment focuses on immobilization to allow healing, often with a cast, boot, or brace. Pain management may include over-the-counter or prescription medications. Weight-bearing restrictions are common initially, with gradual return to activity as healing progresses. Physical therapy may be recommended to restore strength and mobility.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Follow-up appointments are typically scheduled to monitor healing, often with repeat imaging. Full recovery may take 6–8 weeks, depending on the individual and the severity of the injury. Long-term outcomes are generally favorable with adherence to treatment plans.

Complications

• Delayed healing or nonunion if the fracture is not properly immobilized
• Chronic pain or stiffness in the foot
• Post-traumatic arthritis in the affected joint
• Increased risk of future fractures due to weakened bone

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
• Avoid sudden, forceful movements that strain the foot

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, pus, fever). Persistent pain or swelling after initial treatment may also warrant a follow-up with a healthcare provider.

Tips for Medical Coders

Document the encounter as "initial" for a new fracture and specify "closed" to indicate no skin penetration. Include details about the right foot and the nondisplaced nature of the fracture to ensure accurate coding. Verify that the fracture is of the second metatarsal bone and not another toe or foot bone.
