S62.351K Nondisplaced fracture of shaft of second metacarpal bone, left hand, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of shaft of second metacarpal bone, left hand, subsequent encounter for fracture with nonunion

Summary

A nondisplaced fracture of the shaft of the second metacarpal bone in the left hand is a break in the midsection of the bone connecting the index finger to the wrist, where the bone fragments remain aligned. This code applies to a subsequent encounter when the fracture has failed to heal (nonunion) after an initial injury.

Causes

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

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Occupational hazards involving manual labor.
• Poor blood supply to the fracture site.
• Inadequate immobilization during initial 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.
• Lack of healing progress over time.

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 to determine 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 stabilize the fracture or promote healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and treatment effectiveness. Regular follow-up visits are necessary to monitor healing. Long-term outcomes may include persistent pain or reduced hand function if healing is incomplete.

Complications

• Chronic pain or discomfort.
• Reduced range of motion in the hand.
• Potential for arthritis in the affected joint.
• Need for additional surgical intervention.

Lifestyle & Prevention

• Avoid high-impact activities until fully healed.
• Use protective gear during sports or manual labor.
• Maintain bone health through proper nutrition and exercise.
• Follow post-injury care instructions to support healing.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or mobility decreases. Consult a healthcare provider if the fracture does not show signs of healing over time.

Tips for Medical Coders

Document the fracture's status (nondisplaced) and the presence of nonunion. Include details of the encounter type (subsequent) and any treatment provided. Ensure clinical documentation supports the nonunion diagnosis to justify the code.
