S92.351G Displaced fracture of fifth metatarsal bone, right foot, subsequent encounter for fracture with delayed healing

Name of the Condition

• Technical Term: Displaced fracture of fifth metatarsal bone, right foot, subsequent encounter for fracture with delayed healing
• Common Name: Broken fifth metatarsal (right foot) with delayed healing

Summary

A displaced fracture of the fifth metatarsal bone in the right foot, with delayed healing, occurs when the bone breaks and fragments shift out of alignment, and healing progresses more slowly than expected. This is a subsequent encounter, meaning the patient is receiving ongoing care for the fracture. The fifth metatarsal is the long bone on the outer edge of the foot, and delayed healing may require adjusted treatment to promote recovery.

Causes

Direct trauma to the foot, such as a fall, twist, or impact, is the primary cause. Repetitive stress from activities like running or jumping can also lead to fractures over time. Delayed healing may result from factors like poor blood supply, inadequate immobilization, or underlying health conditions affecting bone repair.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer)
• Wearing improper or non-supportive footwear
• Conditions that weaken bones, such as osteoporosis or diabetes
• Advanced age, which may reduce bone density and balance
• Previous foot injuries or fractures
• Smoking or poor nutrition, which can impair healing

Symptoms

• Persistent pain and tenderness on the outer edge of the right foot
• Swelling or bruising that does not resolve with time
• Difficulty bearing weight on the right foot
• Possible deformity if the fracture remains displaced
• Limited range of motion in the foot or ankle

Diagnosis

A healthcare provider will perform a physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays or CT scans, are typically used to confirm the fracture, evaluate alignment, and assess healing progress. Additional tests may be ordered to identify underlying causes of delayed healing, such as blood work or bone scans.

Treatment Options

Treatment focuses on promoting healing and may include:

• Extended immobilization with a cast or boot to stabilize the fracture
• Non-weight-bearing or reduced-weight-bearing activities
• Pain management with medications or physical therapy
• Surgical intervention, such as internal fixation, if healing does not progress
• Addressing underlying conditions (e.g., optimizing nutrition or managing diabetes) to support bone repair

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, adherence to treatment, and any underlying health factors. Most fractures with delayed healing eventually heal with appropriate care, but recovery may take longer than typical fractures. Regular follow-up appointments and imaging are essential to monitor progress and adjust treatment as needed.

Complications

• Nonunion (failure of the bone to heal)
• Malunion (healing in an incorrect position)
• Chronic pain or arthritis in the foot
• Nerve or tissue damage from the injury or treatment
• Increased risk of future fractures due to weakened bone

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities
• Gradually increase activity levels to avoid overuse injuries
• Maintain a healthy diet rich in calcium and vitamin D to support bone health
• Avoid smoking, which can impair healing
• Use protective gear during high-impact sports
• Address underlying conditions that may affect bone strength

When to Seek Professional Help

Seek medical attention if you experience:

• Severe or worsening pain, swelling, or bruising
• Inability to bear weight on the foot
• Signs of infection, such as redness, warmth, or drainage
• Persistent symptoms after initial treatment
• New deformity or loss of function in the foot

Tips for Medical Coders

This code (S92.351G) is used for a displaced fracture of the fifth metatarsal bone in the right foot during a subsequent encounter when healing is delayed. Documentation should specify the fracture type (displaced), location (right foot), encounter type (subsequent), and the reason for delayed healing (e.g., clinical or radiographic evidence of slow progress). Ensure alignment with the ICD-10-CM guidelines for fracture coding and encounter sequencing.
