S62.329G Displaced fracture of shaft of unspecified metacarpal bone, subsequent encounter for fracture with delayed healing

Name of the Condition

• Displaced fracture of shaft of unspecified metacarpal bone, subsequent encounter for fracture with delayed healing

Summary

A displaced fracture of the shaft of an unspecified metacarpal bone involves a break in the middle portion of one of the hand bones (excluding the thumb), where the bone fragments are misaligned. This code is used for a subsequent encounter when the fracture is healing more slowly than expected, requiring ongoing monitoring or intervention. The condition typically results from trauma or impact to the hand, and delayed healing may necessitate additional treatment or adjustments to the care plan.

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 bone.
• Smoking or other factors that impair healing.

Symptoms

• Persistent pain or discomfort at the fracture site.
• Swelling or bruising that does not resolve.
• Limited mobility or stiffness in the hand or fingers.
• Possible deformity or misalignment that remains uncorrected.

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, or deformity. Imaging tests, such as X-rays, to evaluate healing progress and confirm delayed union. Additional tests may be ordered to identify underlying causes of delayed healing, such as blood work or advanced imaging.

Treatment Options

• Continued immobilization with a cast or splint to support healing.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and strength as healing allows.
• Surgical intervention, such as bone grafting or fixation, if healing does not progress.
• Addressing underlying risk factors, such as optimizing nutrition or discontinuing smoking.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient health, and adherence to treatment. Most fractures with delayed healing eventually heal with appropriate care, but recovery may take longer than usual. Follow-up appointments are essential to monitor progress, adjust treatment, and ensure proper alignment. Regular imaging may be used to track healing.

Complications

• Nonunion, where the bone fails to heal.
• Malunion, resulting in improper alignment.
• Chronic pain or stiffness.
• Infection, if surgical intervention is required.
• Reduced hand function or mobility.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking or avoid tobacco products, as they impair healing.
• Use protective gear during sports or manual labor to reduce injury risk.
• Engage in gentle hand exercises as recommended to maintain mobility.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new symptoms (such as numbness or discoloration) develop. Contact a healthcare provider if the fracture site shows signs of infection, such as redness, warmth, or drainage. Prompt evaluation is important if mobility does not improve or if healing delays persist.

Tips for Medical Coders

Use this code for a subsequent encounter when a displaced fracture of the shaft of an unspecified metacarpal bone is documented as having delayed healing. Ensure the encounter is classified as "subsequent" and that the fracture’s delayed healing is clearly noted in the medical record. Verify that the fracture was initially displaced and that the metacarpal bone shaft (not the base, head, or phalangeal joint) is involved. Documentation should support the diagnosis of delayed healing, such as imaging findings or clinical assessment.
