S62.036S Nondisplaced fracture of proximal third of navicular [scaphoid] bone of unspecified wrist, sequela

Name of the Condition

Nondisplaced fracture of proximal third of navicular [scaphoid] bone of unspecified wrist, sequela

Summary

A nondisplaced fracture of the proximal third of the navicular (scaphoid) bone in the unspecified wrist, sequela, refers to a healed or healing fracture in the upper portion of one of the wrist's small bones where the bone fragments remain in their normal alignment. This condition represents the residual effects of a prior fracture, requiring assessment to monitor for long-term complications or functional limitations.

Causes

This sequela results from a previous nondisplaced fracture of the proximal third of the navicular bone, typically caused by trauma such as a fall onto an outstretched hand or direct wrist impact. The sequela phase indicates the fracture has entered a healing or healed state, with residual effects persisting after the acute injury.

Risk Factors

• Prior wrist trauma or fracture history
• Inadequate initial fracture management or healing
• Underlying bone conditions affecting healing (e.g., osteoporosis)
• High-impact activities or occupations increasing wrist injury risk

Symptoms

• Chronic wrist pain, particularly at the thumb base
• Reduced wrist mobility or stiffness
• Occasional swelling or discomfort with activity
• Possible grip weakness or functional limitations

Diagnosis

Clinical evaluation focusing on residual symptoms and functional impact. Imaging (X-ray, CT, or MRI) may be used to assess bone healing and identify any persistent displacement or complications. History of the original fracture and prior treatment is critical for diagnosis.

Treatment Options

• Symptomatic management (pain relief, activity modification)
• Physical therapy to improve mobility and strength
• Orthotic support for stability during daily activities
• Surgical evaluation if functional impairment persists

Prognosis and Follow-Up

Most nondisplaced fractures heal well, but residual symptoms may persist. Prognosis depends on initial injury severity, healing quality, and adherence to rehabilitation. Regular follow-up ensures monitoring for delayed complications like arthritis or instability.

Complications

• Post-traumatic arthritis in the wrist
• Chronic pain or stiffness
• Reduced grip strength or functional limitations
• Rarely, avascular necrosis of the navicular bone

Lifestyle & Prevention

• Avoid repetitive wrist stress or high-impact activities
• Use protective gear during sports or manual labor
• Maintain bone health through proper nutrition and exercise
• Follow-up with a healthcare provider for persistent symptoms

When to Seek Professional Help

Seek care if experiencing increasing pain, swelling, or new functional limitations. Immediate evaluation is needed for sudden severe pain, numbness, or signs of infection (e.g., redness, fever), which may indicate complications.

Tips for Medical Coders

Use this code for a nondisplaced fracture of the proximal third of the navicular bone in the unspecified wrist during the sequela phase. Document the history of the original fracture, healing status, and residual symptoms to support coding. Ensure the sequela designation aligns with the timing and nature of the residual effects.
