S62.343S Nondisplaced fracture of base of third metacarpal bone, left hand, sequela

Name of the Condition

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

Summary

A nondisplaced fracture of the base of the third metacarpal bone in the left hand, sequela, refers to a healed or healing fracture at the base of the bone connecting to the middle finger, where the bone fragments remain properly aligned. This condition represents the residual effects of a prior fracture, such as persistent pain, stiffness, or functional limitations, following the acute injury phase.

Causes

The sequela arises from a previous nondisplaced fracture of the base of the third metacarpal bone in the left hand, typically caused by trauma or direct impact to the hand. The residual effects may persist due to incomplete healing, scar tissue formation, or chronic stress on the affected area.

Risk Factors

• Prior history of hand trauma or fracture.
• Inadequate rehabilitation or immobilization during initial healing.
• Activities that place repetitive stress on the hand, such as manual labor or sports.
• Underlying conditions affecting bone healing, such as poor circulation or nutritional deficiencies.

Symptoms

• Chronic pain or discomfort at the base of the third metacarpal bone.
• Stiffness or reduced range of motion in the middle finger or wrist.
• Mild swelling or tenderness in the affected area.
• Occasional weakness or difficulty with grip strength.

Diagnosis

A healthcare provider evaluates the patient’s history of prior hand injury and performs a physical examination to assess residual symptoms, such as tenderness, stiffness, or functional limitations. Imaging tests, such as X-rays or MRI, may be used to confirm the healed fracture and identify any persistent structural changes.

Treatment Options

• Physical therapy: To improve range of motion, strength, and function.
• Pain management: Using over-the-counter or prescribed medications to alleviate discomfort.
• Activity modification: Avoiding repetitive or high-impact hand activities.
• Assistive devices: Splints or braces to support the hand during daily tasks.

Prognosis and Follow-Up

Most patients experience gradual improvement in symptoms with appropriate treatment, though some residual limitations may persist. Regular follow-up with a healthcare provider ensures monitoring of healing progress and adjustment of treatment plans as needed.

Complications

• Chronic pain or stiffness that does not resolve with treatment.
• Reduced hand function or grip strength.
• Rarely, progression to arthritis in the affected joint over time.

Lifestyle & Prevention

• Engage in regular hand exercises to maintain flexibility and strength.
• Use protective gear during activities with a risk of hand injury.
• Avoid overuse of the affected hand to prevent exacerbation of symptoms.
• Maintain a healthy diet and lifestyle to support overall bone health.

When to Seek Professional Help

Seek medical attention if symptoms worsen, new pain or swelling develops, or functional limitations significantly impact daily activities. Prompt evaluation can help address complications and optimize recovery.

Tips for Medical Coders

Document the sequela status clearly, indicating the prior fracture and its residual effects. Ensure the left-hand specification and nondisplaced nature of the fracture are accurately reflected. Code S62.343S is used for the sequela of a nondisplaced fracture of the base of the third metacarpal bone in the left hand, requiring confirmation of the healed or healing state.
