S62.362K Nondisplaced fracture of neck of third metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

A nondisplaced fracture of the neck of the third metacarpal bone in the right hand, subsequent encounter for fracture with nonunion, refers to a break in the midsection of the third metacarpal bone where the bone fragments remain aligned, but healing has not occurred as expected. This condition indicates a follow-up visit for a fracture that has failed to unite, requiring ongoing management.

Causes

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

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Smoking or poor nutrition affecting bone healing.
• Delayed or inadequate initial treatment.

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 over time 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 and identification of nonunion.

Treatment Options

• 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.
• Surgery may be required to stimulate bone healing or stabilize the fracture.
• Bone grafting or other interventions to address nonunion.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Follow-up visits are necessary to monitor healing and adjust management. Long-term recovery may involve ongoing therapy or surgical intervention.

Complications

• Chronic pain or stiffness.
• Reduced hand function or mobility.
• Infection (if surgery is performed).
• Need for additional interventions to achieve union.

Lifestyle & Prevention

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

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or symptoms do not improve with treatment. Immediate attention is needed for signs of infection, such as redness, warmth, or fever.

Tips for Medical Coders

Document the fracture's status (nondisplaced) and the presence of nonunion. Include details of the encounter (subsequent) and any interventions performed. Ensure documentation supports the need for ongoing management of the nonunion.
