S92.353D Displaced fracture of fifth metatarsal bone, unspecified foot, subsequent encounter for fracture with routine healing

Name of the Condition

• Technical Term: Displaced fracture of fifth metatarsal bone, unspecified foot, subsequent encounter for fracture with routine healing
• ICD-10 Code: S92.353D
• Common Name: Broken fifth metatarsal (unspecified foot, healing)

Summary

A displaced fracture of the fifth metatarsal bone in an unspecified foot, with routine healing, refers to a break where bone fragments have shifted out of alignment, and the fracture is progressing normally during follow-up care. This condition typically follows initial trauma and requires monitoring to ensure proper healing. The fifth metatarsal is the long bone on the outer edge of the foot, and displacement can affect stability and recovery.

Causes

Direct trauma to the foot, such as a fall, twist, or impact, is the primary cause. Sports injuries, missteps, or accidents involving the foot are common triggers. Repetitive stress from activities like running or jumping may also lead to fractures 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 foot
• Swelling or bruising in the affected area
• Difficulty bearing weight on the foot
• Possible deformity if the fracture is severely displaced

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 evaluate healing progress. Follow-up visits may include repeat imaging to monitor alignment and bone union.

Treatment Options

• Immobilization with a cast or boot to stabilize the foot
• Reduced weight-bearing activity to promote healing
• Pain management with medications or therapies
• Physical therapy to restore strength and mobility once healing allows
• Surgical intervention if displacement is severe or healing is delayed

Prognosis and Follow-Up

With proper care, most displaced fifth metatarsal fractures heal within 6–8 weeks. Routine follow-up ensures the fracture is healing as expected, and activity levels can gradually increase. Complications are rare but may include delayed union or malunion if treatment is inadequate.

Complications

• Delayed or improper healing (malunion)
• Chronic pain or instability
• Nerve or soft tissue damage
• Increased risk of future fractures in the same area

Lifestyle & Prevention

• Wear supportive footwear during activities
• Warm up and stretch before exercise
• Avoid sudden, high-impact movements
• Maintain bone health with adequate calcium and vitamin D
• Use protective gear in sports to reduce injury risk

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or weight-bearing becomes impossible. Signs of infection (e.g., redness, fever) or new deformity also require prompt evaluation.

Tips for Medical Coders

Document the encounter type (subsequent) and healing status (routine) to support accurate coding. Include details on fracture alignment, treatment provided, and follow-up imaging results to justify the code. Ensure the unspecified foot designation is appropriate if laterality is not documented.
