S62.313S Displaced fracture of base of third metacarpal bone, left hand, sequela

Name of the Condition

• Displaced fracture of base of third metacarpal bone, left hand, sequela

Summary

A displaced fracture of the base of the third metacarpal bone in the left hand, sequela, refers to the residual effects or complications following the healing of a previous fracture. This condition involves misalignment of the bone fragments at the proximal (base) portion of the third metacarpal, which may result in persistent pain, functional limitations, or deformity. Sequela indicates that the fracture has transitioned from an acute injury to a chronic state with lasting consequences.

Causes

The sequela arises from a prior displaced fracture of the base of the third metacarpal bone in the left hand. The original injury typically resulted from trauma, such as a fall, direct impact, or high-force event affecting the hand. Inadequate healing, malunion, or nonunion of the fracture can lead to long-term structural changes and functional impairment.

Risk Factors

• Incomplete or improper initial treatment of the fracture.
• Delayed or inadequate rehabilitation.
• Underlying conditions affecting bone healing, such as diabetes or vascular disease.
• High-impact activities or occupations that stress the hand.

Symptoms

• Chronic pain or discomfort in the left hand, particularly at the base of the third metacarpal.
• Reduced range of motion or stiffness in the fingers.
• Persistent swelling or deformity.
• Difficulty gripping objects or performing fine motor tasks.
• Possible weakness or instability in the hand.

Diagnosis

A healthcare provider evaluates the patient’s history of the original fracture and assesses current symptoms, including pain, deformity, or functional limitations. Imaging studies, such as X-rays or CT scans, may be used to visualize the healed fracture and identify residual misalignment, malunion, or other structural changes. Functional assessments help determine the impact on daily activities.

Treatment Options

• Orthotic devices or splints to support the hand and improve function.
• Pain management through medications or physical therapy.
• Surgical intervention, if necessary, to correct severe malunion or restore alignment.
• Occupational therapy to adapt activities and improve hand use.

Prognosis and Follow-Up

The prognosis depends on the severity of the residual misalignment and the patient’s response to treatment. Chronic pain or functional limitations may persist, but most patients experience improvement with appropriate management. Regular follow-up appointments monitor healing, functional recovery, and address any new symptoms.

Complications

• Chronic pain or arthritis in the affected joint.
• Persistent deformity or instability.
• Reduced grip strength or dexterity.
• Nerve compression or irritation due to structural changes.

Lifestyle & Prevention

• Avoid activities that strain the hand or risk re-injury.
• Use ergonomic tools or adaptive devices to reduce stress on the hand.
• Engage in regular, gentle hand exercises to maintain mobility.
• Protect the hand during high-risk activities with padding or support.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or swelling develops, or functional limitations interfere with daily tasks. Prompt evaluation is necessary if signs of infection, such as redness or drainage, appear at the site.

Tips for Medical Coders

This code is used for the sequela (residual effect) of a displaced fracture of the base of the third metacarpal bone in the left hand. Document the original fracture and its timeline, as well as the current symptoms and functional impact, to support coding. Ensure the code aligns with the patient’s history and clinical findings, and verify that no acute fracture or active treatment is present.
