S62.245S Nondisplaced fracture of shaft of first metacarpal bone, left hand, sequela

Name of the Condition

• Nondisplaced fracture of shaft of first metacarpal bone, left hand, sequela

Summary

This condition represents a healed or healing nondisplaced fracture of the shaft of the first metacarpal bone (connecting the thumb to the wrist) in the left hand, with residual effects or complications from the prior injury. The fracture fragments remain aligned, but the sequela indicates ongoing or chronic consequences of the original fracture.

Causes

The sequela arises from a prior nondisplaced fracture of the first metacarpal bone shaft, typically caused by direct trauma such as a fall onto an outstretched hand, a blow to the thumb, or a crushing injury. The current condition reflects the long-term effects of that initial event.

Risk Factors

• Prior history of hand or thumb fractures, particularly in the first metacarpal bone.
• Inadequate healing or rehabilitation after the initial fracture.
• Underlying conditions affecting bone or soft tissue recovery (e.g., poor circulation, diabetes).

Symptoms

• Persistent pain, stiffness, or reduced range of motion in the left thumb or hand.
• Mild swelling or deformity at the fracture site.
• Weakness or instability during grip or pinch activities.
• Occasional discomfort with repetitive hand use.

Diagnosis

Clinical evaluation focuses on assessing residual symptoms, functional limitations, and physical findings. Imaging (e.g., X-rays) may be used to confirm healing status or identify sequelae like malunion, though the fracture itself is no longer acute. Documentation should link current findings to the prior fracture event.

Treatment Options

• Rehabilitation: Physical or occupational therapy to improve strength, flexibility, and function.
• Pain Management: NSAIDs or other modalities to address chronic discomfort.
• Assistive Devices: Splints or adaptive tools to support daily activities if needed.
• Surgical Intervention: Rarely required unless significant functional impairment or deformity persists.

Prognosis and Follow-Up

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

Complications

• Chronic pain or stiffness limiting hand use.
• Reduced grip or pinch strength.
• Malunion or nonunion (rare, but possible with inadequate prior treatment).
• Arthritis in the thumb carpometacarpal joint over time.

Lifestyle & Prevention

• Avoid repetitive or high-impact hand activities that exacerbate symptoms.
• Use ergonomic tools or modifications to reduce strain.
• Maintain bone health through proper nutrition and exercise to support overall musculoskeletal integrity.

When to Seek Professional Help

Seek care if symptoms worsen, new pain or deformity develops, or functional limitations interfere with daily tasks. Prompt evaluation is important if signs of infection (e.g., redness, warmth) or nerve compression occur.

Tips for Medical Coders

Document the sequela clearly, linking it to the prior nondisplaced fracture of the first metacarpal bone shaft. Ensure clinical notes specify residual effects (e.g., pain, stiffness, functional impairment) to support the use of this code. Differentiate from acute fractures or other sequelae by confirming the timeline and nature of the ongoing condition.
