S92.346G Nondisplaced fracture of fourth metatarsal bone, unspecified foot, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of fourth metatarsal bone, unspecified foot, subsequent encounter for fracture with delayed healing
• ICD-10 code: S92.346G

Summary

A nondisplaced fracture of the fourth metatarsal bone is a break in the forefoot bone where the fragments remain in their normal alignment. This code applies to a subsequent encounter, indicating the patient is returning for follow-up care, and the fracture is healing more slowly than expected.

Causes

Direct trauma to the foot, such as a fall or impact during physical activity, is a common cause. Stress fractures may also occur from repetitive overuse, particularly in activities involving prolonged weight-bearing or sudden increases in exercise intensity.

Risk Factors

• Participation in high-impact sports (e.g., running, 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

• Persistent pain localized to the outer midfoot area
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the foot
• Possible tenderness to touch

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 alignment. Additional imaging, like MRI or CT, may be ordered if delayed healing is suspected.

Treatment Options

• Extended rest and limited weight-bearing activities to promote healing
• Immobilization with a cast or boot to maintain proper alignment
• Pain management with NSAIDs or acetaminophen
• Possible use of bone stimulators or other interventions to encourage healing

Prognosis and Follow-Up

Prognosis depends on the underlying cause of delayed healing and adherence to treatment. Most fractures eventually heal with appropriate care, but recovery may take longer than usual. Regular follow-up appointments are necessary to monitor progress and adjust treatment as needed.

Complications

• Prolonged pain or discomfort
• Nonunion or malunion of the fracture
• Chronic instability or weakness in the foot
• Increased risk of future fractures

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities
• Gradually increase exercise intensity to avoid overuse injuries
• Maintain bone health through a balanced diet rich in calcium and vitamin D
• Use protective gear during high-impact sports

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or new symptoms develop. Prompt evaluation is important if delayed healing is suspected or if the fracture does not improve with conservative treatment.

Tips for Medical Coders

This code is used for a subsequent encounter for a nondisplaced fracture of the fourth metatarsal bone with delayed healing. Documentation should specify the fracture type, location, and the reason for delayed healing (e.g., poor blood supply, infection, or noncompliance with treatment). Ensure the encounter is coded as subsequent and not initial or routine healing.
