S92.344A Nondisplaced fracture of fourth metatarsal bone, right foot, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of fourth metatarsal bone, right foot, initial encounter for closed fracture
• ICD-10 code: S92.344A

Summary

A nondisplaced fracture of the fourth metatarsal bone in the right foot is a break in the long bone of the forefoot where the bone fragments remain in their normal alignment. This injury typically results from trauma or repetitive stress and is classified as closed (no skin penetration) during the initial encounter. Management focuses on stabilizing the fracture and promoting healing.

Causes

Direct trauma to the foot, such as a fall, impact during sports, or a heavy object dropped on the foot, is a common cause. Stress fractures may also occur from overuse, particularly in activities involving repetitive weight-bearing or sudden increases in physical activity.

Risk Factors

• Participation in high-impact sports (e.g., running, 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 localized to the outer midfoot area of the right foot
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the right foot
• Possible mild tenderness without 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 verify that the bone fragments are nondisplaced. Additional imaging may be considered if a stress fracture is suspected but not visible on initial X-rays.

Treatment Options

Treatment often includes rest, ice, compression, and elevation (RICE) to reduce swelling. Immobilization with a cast, boot, or stiff-soled shoe may be recommended to protect the fracture during healing. Pain management with over-the-counter medications or prescribed analgesics may be used as needed. Weight-bearing restrictions are common initially, with gradual return to activity as healing progresses.

Prognosis and Follow-Up

Most nondisplaced metatarsal fractures heal well with conservative management, typically within 6–8 weeks. Follow-up appointments are important to monitor healing and adjust treatment plans. Physical therapy may be recommended to restore strength and mobility once the fracture is stable.

Complications

While uncommon, potential complications include delayed healing, nonunion (failure to heal), or progression to a displaced fracture if not properly immobilized. Infection is rare but possible if the fracture were open (not applicable here). Chronic pain or arthritis may occur in severe cases.

Lifestyle & Prevention

Wearing supportive, properly fitting footwear during activities can reduce stress on the metatarsals. Gradually increasing physical activity intensity and incorporating strength training for the feet and ankles may help prevent overuse injuries. Maintaining bone health through adequate nutrition (e.g., calcium, vitamin D) is also beneficial.

When to Seek Professional Help

Seek medical attention if pain is severe, worsens, or does not improve with rest; if swelling or bruising is extensive; or if weight-bearing becomes impossible. Prompt evaluation is important to confirm the fracture and rule out other injuries.

Tips for Medical Coders

Document the fracture as nondisplaced and specify the right foot. Note the initial encounter for a closed fracture, as these details are required for accurate coding. Ensure clinical documentation supports the absence of displacement and confirms the fracture is closed (no skin penetration) to align with the code S92.344A.
