S92.355G Nondisplaced fracture of fifth metatarsal bone, left foot, subsequent encounter for fracture with delayed healing

Name of the Condition

• Technical Term: Nondisplaced fracture of fifth metatarsal bone, left foot, subsequent encounter for fracture with delayed healing
• Common Name: Delayed healing of a broken fifth metatarsal (left foot)

Summary

A nondisplaced fracture of the fifth metatarsal bone in the left foot with delayed healing is a break in the outer foot bone where the fragments remain aligned, but the normal healing process has not progressed as expected. This is a subsequent encounter, indicating ongoing care for the fracture, and the delay in healing requires monitoring and potential intervention to promote recovery.

Causes

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

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 can impair bone repair

Symptoms

• Persistent pain and tenderness on the outer edge of the left foot
• Swelling or bruising that does not improve over time
• Difficulty bearing weight on the left foot
• Possible visible or palpable bump at the fracture site

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 used to confirm the fracture and evaluate healing progress. Additional tests may be ordered to identify underlying causes of delayed healing.

Treatment Options

• Extended immobilization with a cast or boot to stabilize the bone
• Weight-bearing restrictions to reduce stress on the fracture
• Physical therapy to maintain mobility and strengthen surrounding muscles
• Medications to manage pain or address underlying conditions (e.g., osteoporosis)
• Surgical intervention, such as bone grafting or fixation, if healing does not improve

Prognosis and Follow-Up

Most fractures with delayed healing eventually heal with proper treatment, but recovery may take longer than typical. Regular follow-up appointments and imaging are necessary to monitor progress. Full weight-bearing and return to activity are gradual and depend on healing status.

Complications

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

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during daily activities and sports
• 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 high-impact sports to reduce injury risk

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or you cannot bear weight on the left foot. Contact a healthcare provider if symptoms persist beyond expected healing timelines or if you notice new deformities or numbness.

Tips for Medical Coders

Document the fracture's alignment (nondisplaced), location (left foot, fifth metatarsal), and the reason for the encounter (subsequent with delayed healing). Include details on imaging results, treatment plans, and any underlying conditions contributing to delayed healing. Ensure documentation supports the "delayed healing" modifier and aligns with the clinical scenario.
