S92.335G Nondisplaced fracture of third metatarsal bone, left foot, subsequent encounter for fracture with delayed healing

Name of the Condition

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

Summary

A nondisplaced fracture of the third metatarsal bone in the left foot is a break in the long bone connecting the ankle to the toes, where the bone fragments remain in their normal alignment. This code applies to a subsequent encounter when healing is delayed, indicating the fracture has not progressed as expected during the healing process. Medical evaluation is necessary to assess healing status and adjust treatment accordingly.

Causes

Direct trauma to the left foot, such as a fall, sports injury, or dropping a heavy object, is a common cause. 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 and tenderness in the midfoot area of the left foot
• Swelling and bruising around the affected bone
• Difficulty bearing weight or walking on the left foot
• Possible delayed reduction in symptoms compared to typical healing timelines

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 to assess bone union or identify complications.

Treatment Options

• Prolonged 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
• Possible use of bone stimulators or other interventions to promote healing
• Surgical evaluation if conservative measures fail to improve healing

Prognosis and Follow-Up

Most nondisplaced fractures heal with time, but delayed healing may extend recovery. Follow-up appointments are essential to monitor progress, with imaging repeated as needed. Full recovery can take several months, depending on the extent of the delay and treatment response.

Complications

• Nonunion, where the bone fails to heal properly
• Malunion, resulting in misalignment of the bone
• Chronic pain or stiffness in the foot
• Increased risk of future fractures in the affected area

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 high-impact activities until cleared by a healthcare provider
• 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. Prompt evaluation is necessary if symptoms persist beyond expected healing timelines or if new symptoms, such as numbness or discoloration, develop.

Tips for Medical Coders

This code is specific to a subsequent encounter for a nondisplaced fracture of the third metatarsal bone in the left foot with delayed healing. Documentation should clearly indicate the fracture type, location, laterality, and the reason for the subsequent encounter (delayed healing). Ensure the medical record supports the diagnosis and any modifiers applied, as coding accuracy depends on detailed clinical documentation.
