S62.364K Nondisplaced fracture of neck of fourth metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of neck of fourth metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Summary

A nondisplaced fracture of the neck of the fourth metacarpal bone in the right hand, with a subsequent encounter for fracture with nonunion, refers to a break in the midsection of the fourth metacarpal bone where the bone fragments remain aligned, but healing has not progressed as expected. This condition occurs after initial treatment and indicates the fracture site has failed to unite properly.

Causes

Direct trauma, such as a fall or blow to the hand. Sports-related injuries or accidents. Repetitive stress or overuse. Inadequate immobilization during initial healing.

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Poor blood supply to the fracture site.
• Smoking or other factors that impair bone healing.

Symptoms

• Persistent pain and swelling in the hand.
• Tenderness or bruising around the affected area.
• Difficulty moving the fingers or hand.
• Possible deformity or misalignment.
• No improvement in symptoms despite prior treatment.

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, or deformity. Imaging tests, such as X-rays, to confirm the fracture and evaluate its extent. Assessment of healing progress over time to determine nonunion.

Treatment Options

• Extended immobilization with a cast or splint to promote healing.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and strength.
• Surgical intervention, such as bone grafting or internal fixation, to stimulate union.
• Use of electrical stimulation or other adjunctive therapies to enhance bone healing.

Prognosis and Follow-Up

Prognosis depends on the success of treatment and the underlying factors contributing to nonunion. Regular follow-up with imaging is necessary to monitor healing. Most patients can expect improved function with appropriate intervention, though recovery may be prolonged.

Complications

• Chronic pain or discomfort.
• Persistent swelling or stiffness.
• Reduced range of motion in the hand or fingers.
• Risk of further injury to the weakened bone.
• Potential need for additional surgery if nonunion persists.

Lifestyle & Prevention

• Avoid high-impact activities until fully healed.
• Use protective gear during sports or manual labor.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Follow post-treatment instructions carefully to optimize healing.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility does not improve with treatment. Contact a healthcare provider if signs of infection, such as redness, warmth, or pus, develop at the fracture site.

Tips for Medical Coders

Document the fracture site, laterality (right hand), and the presence of nonunion. Include details of prior treatments and the reason for the subsequent encounter. Ensure clinical notes support the diagnosis and any interventions performed.
