S92.326G Nondisplaced fracture of second metatarsal bone, unspecified foot, subsequent encounter for fracture with delayed healing

Name of the Condition

• Technical Term: Nondisplaced fracture of second metatarsal bone, unspecified foot, subsequent encounter for fracture with delayed healing
• ICD-10 Code: S92.326G
• Common Name: Broken second metatarsal (unspecified foot), delayed healing, follow-up

Summary

A nondisplaced fracture of the second metatarsal bone in the unspecified foot is a break where the bone fragments remain aligned, but healing has not progressed as expected during a subsequent encounter. This condition occurs when the fracture site shows delayed union, requiring ongoing monitoring and potential intervention. The second metatarsal, a weight-bearing bone in the midfoot, is prone to injury from trauma or repetitive stress. Treatment focuses on addressing healing delays, which may involve immobilization, physical therapy, or additional imaging to assess progress.

Causes

Direct trauma to the foot, such as a fall, sports injury, or heavy impact, is the primary cause. Repetitive stress from activities like running or jumping can lead to stress fractures over time. Twisting the foot or sudden force may also result in a fracture, particularly in high-impact scenarios. Delayed healing may stem from inadequate immobilization, poor blood supply to the bone, or underlying 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 healing capacity
• Smoking or poor nutrition, which impairs bone repair
• Previous foot injuries or fractures

Symptoms

• Persistent pain at the fracture site, often worsening with activity
• Swelling or bruising that does not resolve over time
• Difficulty bearing weight or walking on the injured foot
• Limited range of motion in the midfoot
• Possible clicking or grinding sensations during movement

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and mobility. Imaging, typically X-rays, is used to confirm the fracture and evaluate healing progress. If delayed healing is suspected, additional tests like CT scans or MRIs may be ordered to assess bone union and rule out complications. The clinician will review the patient’s history, including prior treatment and activity levels, to determine the cause of the delay.

Treatment Options

Treatment focuses on promoting healing and may include extended immobilization with a cast or boot to reduce stress on the bone. Physical therapy can help restore strength and mobility once healing progresses. In some cases, bone stimulation devices or surgical intervention may be considered to encourage union. Pain management and activity modification are also key components of care.

Prognosis and Follow-Up

Prognosis depends on the underlying cause of delayed healing and the patient’s overall health. Most fractures eventually heal with appropriate management, but recovery may take longer than usual. Regular follow-up appointments, including imaging, are necessary to monitor progress. Patients should avoid high-impact activities until cleared by a healthcare provider to prevent further injury.

Complications

• Nonunion, where the bone fails to heal completely
• Malunion, resulting in misalignment of the bone fragments
• Chronic pain or arthritis in the affected foot
• Increased risk of future fractures due to weakened bone
• Nerve or tissue damage from prolonged immobilization

Lifestyle & Prevention

• Wear supportive, properly fitting footwear to reduce stress on the feet
• Gradually increase activity levels to avoid overuse injuries
• Maintain a balanced diet rich in calcium and vitamin D to support bone health
• Avoid smoking and limit alcohol, which can impair healing
• Use protective gear during sports or high-risk activities

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility declines. Contact a healthcare provider if you experience numbness, tingling, or signs of infection (e.g., redness, fever). Prompt evaluation is important if healing does not progress as expected or if symptoms return after initial improvement.

Tips for Medical Coders

This code (S92.326G) is used for a subsequent encounter where healing is delayed. Documentation should specify the fracture type (nondisplaced), location (second metatarsal, unspecified foot), and the reason for delayed healing (e.g., inadequate immobilization, poor blood supply). Ensure the encounter is classified as "subsequent" and that the delay in healing is clearly noted to support code assignment.
