S62.345S Nondisplaced fracture of base of fourth metacarpal bone, left hand, sequela

Name of the Condition

• Nondisplaced fracture of base of fourth metacarpal bone, left hand, sequela

Summary

A nondisplaced fracture of the base of the fourth metacarpal bone in the left hand, sequela, refers to a healed or healing fracture at this site with residual effects. The bone fragments remained properly aligned during the initial injury, and the "sequela" designation indicates ongoing consequences of the prior fracture, such as chronic pain, stiffness, or functional limitations.

Causes

The initial fracture typically results from direct trauma, such as a fall onto the hand or a blow to the area. Sports-related injuries, accidents, or repetitive stress may also lead to this type of fracture. The sequela arises as a result of the healing process or incomplete recovery from the original injury.

Risk Factors

• Participation in activities with a risk of hand trauma, such as contact sports or manual labor.
• Reduced bone density, which can increase susceptibility to fractures.
• Inadequate hand protection during high-risk activities.
• Prior history of hand fractures or injuries.

Symptoms

• Chronic pain or discomfort at the base of the fourth metacarpal bone.
• Stiffness or limited range of motion in the ring finger.
• Swelling or tenderness in the affected area.
• Possible functional limitations, such as difficulty gripping or performing fine motor tasks.

Diagnosis

Physical examination by a healthcare provider to assess residual tenderness, swelling, or deformity. Imaging tests, such as X-rays, may be used to evaluate the healing status of the fracture and identify any persistent alignment issues or bone changes. Clinical correlation with the patient’s history of the prior injury is essential.

Treatment Options

• Rehabilitation and physical therapy: To improve strength, flexibility, and function.
• Pain management using over-the-counter or prescription medications.
• Assistive devices, such as splints or braces, to support the hand during activity.
• Surgical evaluation if significant functional impairment or deformity is present.

Prognosis and Follow-Up

Most patients experience gradual improvement with appropriate treatment, though some residual symptoms may persist. Follow-up care focuses on monitoring functional recovery and addressing any ongoing issues. Long-term outcomes depend on the severity of the initial injury and adherence to rehabilitation.

Complications

• Chronic pain or arthritis in the affected joint.
• Persistent stiffness or reduced mobility.
• Nerve or tendon irritation from scar tissue or bone changes.
• Increased risk of reinjury due to weakened bone or altered mechanics.

Lifestyle & Prevention

• Use protective gear during high-risk activities to minimize trauma.
• Engage in exercises to maintain hand strength and flexibility.
• Avoid repetitive stress on the hand and wrist.
• Follow post-injury rehabilitation plans to optimize recovery.

When to Seek Professional Help

Seek medical attention if symptoms worsen, new pain or swelling develops, or functional limitations interfere with daily activities. Prompt evaluation is important if signs of infection, such as redness, warmth, or drainage, are present.

Tips for Medical Coders

This code is used for a nondisplaced fracture of the base of the fourth metacarpal bone in the left hand during the sequela phase, indicating residual effects of a prior injury. Documentation should specify the nature of the sequela (e.g., chronic pain, stiffness) and confirm the prior fracture history. Ensure the code aligns with the patient’s current clinical status and treatment plan.
