S92.353S Displaced fracture of fifth metatarsal bone, unspecified foot, sequela

Name of the Condition

• Technical Term: Displaced fracture of fifth metatarsal bone, unspecified foot, sequela
• ICD-10 Code: S92.353S
• Common Name: Broken fifth metatarsal (unspecified foot, sequela)

Summary

A displaced fracture of the fifth metatarsal bone in the unspecified foot, sequela, refers to the residual effects of a previously treated fracture. This condition occurs after the initial injury has healed, and the sequela may include persistent pain, deformity, or functional limitations. The fifth metatarsal is the long bone on the outer edge of the foot, and displacement during the original fracture can lead to long-term consequences that require ongoing management.

Causes

The sequela arises from a prior displaced fracture of the fifth metatarsal bone. The original injury may have resulted from trauma, repetitive stress, or other factors that caused the bone to break and shift out of alignment. The residual effects are a direct consequence of the initial fracture and its healing process.

Risk Factors

• Inadequate initial treatment or nonunion of the original fracture
• Poor bone healing due to underlying conditions (e.g., osteoporosis, diabetes)
• High-impact activities or sports that stress the foot
• Previous foot injuries or fractures
• Advanced age, which may affect bone density and recovery

Symptoms

• Chronic pain or discomfort in the outer edge of the foot
• Swelling or tenderness in the affected area
• Difficulty bearing weight or walking
• Possible deformity or altered foot mechanics
• Reduced range of motion in the foot or ankle

Diagnosis

Diagnosis involves a clinical evaluation of the foot, including a review of the patient’s medical history and prior fracture. Imaging studies, such as X-rays or MRI, may be used to assess the current state of the bone and identify residual displacement or healing issues. The provider will also evaluate functional limitations and any ongoing symptoms.

Treatment Options

Treatment focuses on managing symptoms and improving function. Options may include physical therapy to strengthen surrounding muscles, orthotic devices or supportive footwear, pain management, or, in severe cases, surgical intervention to correct residual deformity. The approach depends on the extent of the sequela and the patient’s activity level.

Prognosis and Follow-Up

Prognosis varies based on the severity of the sequela and the effectiveness of treatment. Many patients experience improved function with appropriate care, though some may have persistent limitations. Regular follow-up appointments are important to monitor healing, adjust treatment, and address any new symptoms.

Complications

• Chronic pain or discomfort
• Persistent deformity affecting gait or balance
• Increased risk of future foot injuries
• Limited mobility or activity restrictions
• Potential need for additional interventions if symptoms worsen

Lifestyle & Prevention

• Wear supportive footwear to reduce stress on the foot
• Avoid high-impact activities that may exacerbate symptoms
• Engage in low-impact exercises to maintain strength and flexibility
• Maintain a healthy weight to reduce foot strain
• Follow up with a healthcare provider for ongoing management

When to Seek Professional Help

Seek medical attention if you experience worsening pain, new swelling, difficulty walking, or signs of infection (e.g., redness, warmth). Prompt evaluation is important to address complications and adjust treatment as needed.

Tips for Medical Coders

This code is used for the sequela of a displaced fifth metatarsal fracture. Document the relationship to the original injury, including the time elapsed since the fracture and any residual effects. Ensure the code is reported only when the sequela is the focus of the encounter, and verify that no other codes for the initial fracture or acute phase are used concurrently.
