S92.354B Nondisplaced fracture of fifth metatarsal bone, right foot, initial encounter for open fracture

Name of the Condition

• Technical Term: Nondisplaced fracture of fifth metatarsal bone, right foot, initial encounter for open fracture
• ICD-10 Code: S92.354B
• Common Name: Broken fifth metatarsal (right foot, open fracture)

Summary

A nondisplaced fracture of the fifth metatarsal bone in the right foot, with an open fracture, involves a break in the long bone on the outer edge of the foot where the bone fragments remain in their normal alignment but the skin is broken, exposing the fracture site. This injury typically results from trauma and requires prompt medical attention to prevent infection and ensure proper healing.

Causes

Direct trauma to the right foot, such as a fall, twist, or impact, is the primary cause. Open fractures occur when the force of the injury breaks the skin, allowing the fracture site to be exposed to the external environment. Repetitive stress or high-impact activities may also contribute to such injuries 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 and balance
• Previous foot injuries or fractures

Symptoms

• Pain and tenderness on the outer edge of the right foot
• Swelling or bruising in the affected area
• Difficulty bearing weight or walking on the right foot
• Visible skin break or wound near the fracture site
• Possible bleeding or discharge from the open wound

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 alignment. The open wound will also be evaluated for signs of infection or contamination.

Treatment Options

• Immediate wound care to clean and dress the open fracture site
• Immobilization with a cast or splint to stabilize the bone
• Antibiotics to prevent infection
• Pain management with medications
• Surgical intervention if the fracture is unstable or the wound is severe
• Follow-up care to monitor healing and wound closure

Prognosis and Follow-Up

With proper treatment, most nondisplaced open fractures of the fifth metatarsal heal well, though the risk of infection is higher due to the open wound. Follow-up appointments are necessary to assess healing, remove sutures or dressings, and adjust treatment as needed. Full recovery may take several weeks to months, depending on the severity of the injury.

Complications

• Infection at the fracture site
• Delayed healing or nonunion
• Chronic pain or instability
• Nerve or tissue damage from the injury
• Scarring or deformity at the wound site

Lifestyle & Prevention

• Wear supportive, properly fitted footwear during activities
• Use protective gear (e.g., ankle braces) during high-impact sports
• Maintain bone health with a balanced diet and regular exercise
• Avoid activities that increase the risk of foot trauma
• Seek prompt medical care for any foot injuries to prevent complications

When to Seek Professional Help

• Severe pain, swelling, or bleeding that does not improve
• Visible bone or tissue protruding from the wound
• Signs of infection, such as redness, warmth, or pus
• Inability to bear weight on the right foot
• Fever or chills, which may indicate infection

Tips for Medical Coders

Document the location (right foot), fracture type (nondisplaced), and encounter type (initial) clearly. Note the open fracture status, as this impacts coding and treatment considerations. Ensure documentation supports the absence of displacement and the initial nature of the encounter to align with the code S92.354B.
