S92.354A Nondisplaced fracture of fifth metatarsal bone, right foot, initial encounter for closed fracture

Name of the Condition

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

Summary

A nondisplaced fracture of the fifth metatarsal bone in the right foot is a break where the bone fragments remain in their normal alignment. This injury typically results from trauma or repetitive stress and is classified as a closed fracture (no open wound) during the initial encounter. The fifth metatarsal is the long bone on the outer edge of the foot, and a nondisplaced fracture often has a better prognosis for healing compared to displaced fractures.

Causes

Direct trauma to the right foot, such as a fall, twist, or impact, is the most common cause. Repetitive stress from activities like running or jumping may also lead to stress fractures over time. The fracture is considered closed, meaning the skin remains intact, and it is documented during the initial encounter (first visit for the injury).

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
• Minimal deformity, as the fracture is nondisplaced

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 it is nondisplaced. The closed nature of the fracture (no open wound) and the initial encounter status are documented during evaluation.

Treatment Options

• Rest and reduced activity to allow healing
• Immobilization with a cast, boot, or brace to stabilize the foot
• Pain management with over-the-counter or prescription medications
• Physical therapy to restore strength and mobility after healing
• Follow-up imaging to ensure proper alignment and healing progress

Prognosis and Follow-Up

Most nondisplaced fractures of the fifth metatarsal heal well with conservative treatment. Recovery typically takes 6–8 weeks, depending on the individual and fracture severity. Follow-up appointments are important to monitor healing and adjust treatment as needed. Return to normal activities is gradual, guided by pain and functional improvement.

Complications

• Delayed healing or nonunion (failure to heal)
• Malalignment if the fracture shifts during recovery
• Chronic pain or stiffness in the foot
• Increased risk of future fractures in the same area

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities
• Gradually increase activity intensity to avoid overuse injuries
• Maintain bone health through a balanced diet and regular exercise
• Use protective gear (e.g., ankle braces) during high-impact sports
• Address underlying conditions like osteoporosis to reduce fracture risk

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Severe pain, swelling, or deformity in the right foot
• Inability to bear weight or walk
• Signs of infection (e.g., redness, warmth, fever) if the fracture was initially closed but later becomes open
• Worsening symptoms despite initial treatment

Tips for Medical Coders

Document the fracture as nondisplaced, right foot, and closed (no open wound) during the initial encounter. Ensure the "initial encounter" status is clearly recorded to distinguish it from subsequent encounters (e.g., follow-up or healing). Verify that imaging confirms the fracture is nondisplaced and that the right foot is specifically noted to match the code.
