S62.349S Nondisplaced fracture of base of unspecified metacarpal bone, sequela

Name of the Condition

• Nondisplaced fracture of base of unspecified metacarpal bone, sequela

Summary

A nondisplaced fracture of the base of an unspecified metacarpal bone, sequela, refers to the residual effects or complications that persist after the initial healing phase of a fracture in the base of one of the hand bones (excluding the thumb). The bone fragments remain in their normal alignment, but ongoing symptoms or functional limitations may occur due to the prior injury.

Causes

This condition arises as a consequence of a previous nondisplaced fracture of the base of an unspecified metacarpal bone. The sequela develops during the healing process or as a result of incomplete recovery.

Risk Factors

• Prior history of metacarpal fracture.
• Inadequate initial treatment or rehabilitation.
• Underlying conditions affecting bone healing, such as poor circulation or nutritional deficiencies.

Symptoms

• Persistent pain or discomfort at the fracture site.
• Reduced range of motion or stiffness in the affected finger.
• Mild swelling or deformity that does not resolve.
• Weakness or difficulty with grip strength.

Diagnosis

Physical examination to assess residual tenderness, swelling, or functional limitations. Imaging tests, such as X-rays, to evaluate bone healing and identify any persistent abnormalities. Review of prior injury and treatment history to confirm the sequela.

Treatment Options

• Rehabilitation and physical therapy: To improve mobility, strength, and function.
• Pain management with medications or modalities like heat/cold therapy.
• Orthotic devices or splints to support the hand during daily activities.
• Surgical intervention may be considered for severe functional impairment or unresolved symptoms.

Prognosis and Follow-Up

Most patients experience gradual improvement with appropriate rehabilitation, though some residual symptoms may persist. Regular follow-up appointments monitor progress and adjust treatment plans as needed. Full recovery depends on the severity of the initial injury and adherence to therapy.

Complications

• Chronic pain or stiffness.
• Reduced hand function or grip strength.
• Post-traumatic arthritis in the affected joint.
• Nerve or tendon irritation from scar tissue.

Lifestyle & Prevention

• Engage in gentle hand exercises to maintain flexibility.
• Use ergonomic tools or adaptive devices to reduce strain.
• Protect the hand during activities to prevent re-injury.
• 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, warmth) or nerve damage (e.g., numbness, tingling) occur.

Tips for Medical Coders

Document the history of the prior fracture and the nature of the sequela (e.g., persistent pain, functional impairment) to support coding. Ensure the encounter is coded as a sequela (S62.349S) only when the condition is a direct result of the initial fracture and not an active, acute injury.
