S62.348S Nondisplaced fracture of base of other metacarpal bone, sequela

Name of the Condition

• Nondisplaced fracture of base of other metacarpal bone, sequela

Summary

A nondisplaced fracture of the base of another metacarpal bone (excluding the thumb) with sequela refers to a residual condition following a prior fracture. The bone fragments remain in their normal alignment, but the sequela indicates ongoing effects or complications from the original injury. This may include persistent pain, limited mobility, or other long-term consequences of the healed fracture.

Causes

The sequela arises from a previous nondisplaced fracture of the base of a metacarpal bone, typically caused by trauma such as a fall, blow to the hand, or sports-related injury. The original fracture heals, but residual effects persist.

Risk Factors

• Prior history of metacarpal fracture.
• Inadequate rehabilitation or immobilization during initial healing.
• Underlying conditions affecting bone healing (e.g., poor circulation, diabetes).

Symptoms

• Chronic pain or discomfort at the fracture site.
• Reduced range of motion in the affected finger.
• Stiffness or weakness in the hand.
• Possible deformity or altered function of the metacarpal bone.

Diagnosis

Physical examination to assess residual tenderness, swelling, or functional limitations. Imaging (e.g., X-rays) may be used to evaluate bone healing and identify any persistent abnormalities. The diagnosis confirms the sequela status of a previously fractured metacarpal base.

Treatment Options

• Rehabilitation and physical therapy: To improve mobility, strength, and function.
• Pain management with medications or modalities (e.g., heat, cold).
• Orthotic devices or splints to support the hand during daily activities.
• Surgical intervention (rare) for severe residual deformity or functional impairment.

Prognosis and Follow-Up

Prognosis depends on the severity of the sequela and adherence to rehabilitation. Most patients experience gradual improvement with therapy, though some may have permanent limitations. Regular follow-up with a healthcare provider is recommended to monitor progress and adjust treatment as needed.

Complications

• Chronic pain or arthritis at the fracture site.
• Persistent stiffness or reduced dexterity.
• Nerve or tendon irritation from scar tissue.
• Increased risk of re-injury due to weakened bone or altered mechanics.

Lifestyle & Prevention

• Avoid repetitive or high-impact hand activities that may exacerbate symptoms.
• Use ergonomic tools or protective gear during work or sports.
• Perform regular hand exercises to maintain flexibility and strength.
• Maintain overall bone health through proper nutrition and exercise.

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 important if signs of infection (e.g., redness, discharge) or nerve compression (e.g., numbness, tingling) occur.

Tips for Medical Coders

Document the sequela status clearly, noting the prior fracture and its residual effects. Ensure the code S62.348S is used only when the condition represents a late effect of a healed fracture, not an acute injury. Include details about functional limitations or chronic symptoms to support the sequela designation.
