S62.318D Displaced fracture of base of other metacarpal bone, subsequent encounter for fracture with routine healing

Name of the Condition

• Displaced fracture of base of other metacarpal bone, subsequent encounter for fracture with routine healing

Summary

A displaced fracture of the base of another metacarpal bone, subsequent encounter for fracture with routine healing, refers to a break in the proximal (base) portion of one of the hand bones (excluding the thumb) where the bone fragments are misaligned. This code applies during a follow-up visit when the fracture is healing as expected without complications. The injury typically results from trauma or impact to the hand and is classified as routine healing, indicating normal progress toward recovery.

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.

Symptoms

• Pain and swelling in the hand, though typically reduced from initial injury.
• Tenderness or mild bruising around the affected area.
• Gradual improvement in hand mobility and function.
• Possible residual stiffness or discomfort during movement.

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 and alignment.

Treatment Options

• Continued immobilization with a cast or splint if needed to support healing.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility, strength, and function.
• Monitoring of healing progress through follow-up visits and imaging.

Prognosis and Follow-Up

With routine healing, most fractures of this type heal within the expected timeframe, typically 6–8 weeks, depending on the severity. Follow-up care focuses on assessing progress, adjusting treatment as needed, and ensuring full functional recovery. Regular check-ins with a healthcare provider are important to confirm proper healing and address any concerns.

Complications

• Delayed union or nonunion of the fracture.
• Persistent pain or stiffness.
• Reduced range of motion in the hand or fingers.
• Rarely, malunion or deformity if alignment is not fully restored.

Lifestyle & Prevention

• Use protective gear during high-risk activities, such as sports or manual labor.
• Maintain bone health through a balanced diet rich in calcium and vitamin D.
• Avoid repetitive stress on the hand by taking breaks during prolonged activities.
• Practice proper hand positioning and ergonomics to reduce injury risk.

When to Seek Professional Help

• Increased pain, swelling, or bruising that worsens over time.
• Difficulty moving the hand or fingers despite treatment.
• Signs of infection, such as redness, warmth, or pus at the injury site.
• New or worsening deformity in the hand or fingers.

Tips for Medical Coders

This code is used for a subsequent encounter when the fracture is healing routinely. Documentation should specify the fracture type (displaced), location (base of other metacarpal bone), and healing status (routine). Ensure the encounter is classified as subsequent and that there is no indication of delayed healing, nonunion, or complications. Code S62.318D is specific to the base of other metacarpal bones (excluding the thumb) and requires clear documentation of the healing phase.
