S62.311K Displaced fracture of base of second metacarpal bone, left hand, subsequent encounter for fracture with nonunion

Name of the Condition

• Displaced fracture of base of second metacarpal bone, left hand, subsequent encounter for fracture with nonunion

Summary

A displaced fracture of the base of the second metacarpal bone in the left hand is a break in the proximal portion of the bone where fragments are misaligned. This encounter indicates a subsequent visit for a fracture that has failed to heal (nonunion) after an initial injury. The condition typically results from trauma to the hand and requires evaluation to determine the extent of nonunion and appropriate management.

Causes

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

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Occupational hazards involving manual labor or repetitive hand movements.
• Poor blood supply to the fracture site.
• Inadequate initial immobilization or treatment.

Symptoms

• Persistent pain and swelling in the left hand.
• Tenderness or bruising around the affected area.
• Difficulty moving the fingers or gripping objects.
• Possible visible deformity or misalignment.
• Lack of healing progress over time.

Diagnosis

Physical examination by a healthcare provider to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, to confirm the fracture and evaluate the extent of nonunion. Assessment of healing progress compared to expected timelines.

Treatment Options

• Surgical intervention to promote healing, such as bone grafting or internal fixation.
• Immobilization with a cast or splint to stabilize the fracture.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and function.

Prognosis and Follow-Up

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

Complications

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

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or manual labor.
• Maintain bone health through proper nutrition and exercise.
• Follow post-treatment instructions to support healing.

When to Seek Professional Help

Seek immediate medical attention if pain worsens, swelling increases, or new symptoms (e.g., numbness, discoloration) develop. Follow up with a healthcare provider if healing does not progress as expected.

Tips for Medical Coders

Document the fracture's status (nonunion) and the encounter type (subsequent) clearly in the medical record. Ensure imaging or clinical notes confirm the nonunion to support coding. Verify that the left-hand involvement and displacement are documented to align with the code.
