S62.366K Nondisplaced fracture of neck of fifth metacarpal bone, right hand, subsequent encounter for fracture with nonunion

Name of the Condition

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

Summary

A nondisplaced fracture of the neck of the fifth metacarpal bone in the right hand, with nonunion, is a break in the midsection of the fifth metacarpal bone where the bone fragments remain aligned but have failed to heal properly. The term "subsequent encounter" indicates this is a follow-up visit for the fracture, and "nonunion" refers to the lack of bone healing after an expected timeframe.

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 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 to determine nonunion. Additional tests, like CT scans, may be used to evaluate bone union.

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.
• Surgery may be required to stimulate bone healing, such as bone grafting or internal fixation.
• Electrical stimulation or other advanced techniques to encourage union.

Prognosis and Follow-Up

Prognosis depends on the success of treatment to achieve bone union. Follow-up visits are necessary to monitor healing progress. Long-term outcomes may include persistent pain or reduced hand function if nonunion persists. Regular imaging and clinical assessments guide ongoing care.

Complications

• Chronic pain or discomfort.
• Reduced range of motion in the hand or fingers.
• Increased risk of arthritis in the affected joint.
• Need for additional surgeries if nonunion does not resolve.
• Potential for permanent disability if untreated.

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-treatment instructions carefully to support healing.
• Seek early treatment for fractures to reduce nonunion risk.

When to Seek Professional Help

• Persistent pain or swelling after initial treatment.
• Inability to move the hand or fingers normally.
• Signs of infection, such as redness, warmth, or pus.
• No improvement in symptoms over several weeks.
• New or worsening deformity in the hand.

Tips for Medical Coders

Document the fracture type (nondisplaced), location (neck of fifth metacarpal, right hand), and encounter type (subsequent) clearly. Specify "nonunion" to indicate failed healing. Include details on prior treatments, imaging results, and clinical assessments to support the diagnosis. Ensure documentation aligns with the code’s definition for accurate coding.
