S92.336G Nondisplaced fracture of third metatarsal bone, unspecified foot, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of third metatarsal bone, unspecified foot, subsequent encounter for fracture with delayed healing.

Summary

This condition describes a break in the third metatarsal bone of the foot where the bone fragments remain in their normal alignment, and healing is progressing more slowly than expected. The term "subsequent encounter" indicates this is a follow-up visit for the fracture, and "delayed healing" specifies that the fracture has not healed within the typical timeframe.

Causes

The fracture is typically caused by direct trauma to the foot, such as a heavy object falling or a twisting injury. Repetitive stress from activities like running or jumping can also lead to stress fractures over time. Delayed healing may occur due to factors like poor blood supply, inadequate immobilization, or underlying health conditions.

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
• Previous foot injuries or fractures
• Smoking or poor nutrition, which can impair healing

Symptoms

• Persistent pain, swelling, or tenderness in the midfoot region
• Difficulty bearing weight or walking on the affected foot
• Bruising or discoloration around the area
• Possible limited range of motion in the foot

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. Additional tests, like CT scans or MRIs, may be ordered if delayed healing is suspected.

Treatment Options

• Extended immobilization, such as a cast or walking boot, to support healing
• Pain management with over-the-counter or prescription medications
• Physical therapy to restore strength and mobility once healing allows
• In some cases, surgical intervention may be considered to stabilize the fracture

Prognosis and Follow-Up

Most nondisplaced fractures with delayed healing eventually heal with proper care, though recovery may take longer than usual. Follow-up appointments are important to monitor progress and adjust treatment as needed. Full recovery can take several months, depending on the severity and individual factors.

Complications

• Nonunion, where the bone fails to heal properly
• Malunion, where the bone heals in an incorrect position
• Chronic pain or stiffness in the foot
• Increased risk of future fractures due to weakened bone

Lifestyle & Prevention

• Wear supportive, properly fitting footwear to reduce stress on the foot
• Avoid high-impact activities until cleared by a healthcare provider
• Maintain a healthy diet rich in calcium and vitamin D to support bone health
• Gradually resume activity as healing progresses to prevent re-injury

When to Seek Professional Help

Seek medical attention if you experience severe pain, swelling that worsens, inability to bear weight, or signs of infection (e.g., redness, warmth, or drainage) around the fracture site.

Tips for Medical Coders

Document the encounter as a subsequent visit for a fracture with delayed healing. Ensure clinical notes specify the fracture is nondisplaced and involve the third metatarsal bone of an unspecified foot. Include details about healing progress and any interventions provided to support accurate coding.
