S62.363K Nondisplaced fracture of neck of third metacarpal bone, left hand, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

A nondisplaced fracture of the neck of the third metacarpal bone in the left hand, with nonunion, refers to a break in the midsection of the third metacarpal bone where the bone fragments remain aligned but have failed to heal properly. This condition occurs during a subsequent encounter for care, indicating ongoing management of the fracture. Nonunion means the bone has not fused within the expected timeframe, often requiring additional intervention.

Causes

Direct trauma, such as a fall or blow to the hand. Sports-related injuries or accidents. Repetitive stress or overuse. Inadequate initial treatment or immobilization. Poor blood supply to the fracture site.

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Occupational hazards involving manual labor.
• Smoking or poor nutrition, which can impair healing.
• Certain medical conditions, such as diabetes or infections.

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 healing progress. Assessment for signs of nonunion, such as a visible gap or lack of bone fusion. Additional tests, like CT scans, may be used to assess bone density or blood flow.

Treatment Options

• Immobilization with a cast or splint to promote healing, if not already attempted.
• 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 healing.
• Electrical stimulation or other advanced therapies to encourage bone growth.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. With proper intervention, many fractures can eventually heal, but recovery may be prolonged. Regular follow-up appointments and imaging are necessary to monitor progress. Long-term mobility and function are generally good if healing occurs, but some residual stiffness or weakness may persist.

Complications

• Chronic pain or discomfort.
• Limited range of motion in the hand or fingers.
• Increased risk of future fractures due to weakened bone.
• Infection, particularly if surgery is required.
• Nerve or tendon damage in severe cases.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it impairs healing.
• Use protective gear during sports or manual labor.
• Follow post-treatment instructions carefully to optimize healing.

When to Seek Professional Help

Seek immediate care if pain worsens, swelling increases, or new symptoms like numbness or discoloration develop. Contact a healthcare provider if symptoms do not improve after initial treatment or if there are signs of infection, such as fever or pus.

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture care with nonunion. Include details about the fracture's status, treatment provided, and any imaging results confirming nonunion. Ensure the left-hand specificity and metacarpal bone location are clearly noted. Use this code only when the fracture has failed to heal and requires ongoing management.
