S62.161A Displaced fracture of pisiform, right wrist, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of pisiform, right wrist, initial encounter for closed fracture

Summary

This condition involves a break in the pisiform bone, a small, pea-shaped carpal bone on the palmar (palm) side of the right wrist, with displacement of bone fragments. The fracture is closed (skin intact) and is the initial encounter for this injury. The pisiform is embedded in the flexor carpi ulnaris tendon and contributes to wrist stability. Displacement may affect alignment and require specific management to ensure proper healing.

Causes

Typically caused by direct trauma to the right wrist, such as a fall onto an outstretched hand, a blow to the palmar side of the wrist, or a crushing injury. High-impact activities or accidents may also lead to this type of fracture.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or weakened bone structure, especially in older adults.
• Previous wrist injuries or fractures.

Symptoms

• Pain, swelling, and tenderness in the palmar side of the right wrist.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the hand or fingers.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture, evaluate displacement, and rule out associated injuries.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the area and promote healing.
• Pain management: Medications like NSAIDs to reduce pain and inflammation.
• Physical therapy: To restore strength and range of motion after immobilization.
• Surgical intervention: May be required for severe displacement or unstable fractures.

Prognosis and Follow-Up

Most fractures heal with proper immobilization and care, but recovery time depends on fracture severity and treatment. Follow-up appointments monitor healing progress, and physical therapy may be recommended to regain full function. Long-term outcomes are generally good with appropriate management.

Complications

• Nonunion or malunion of the fracture.
• Chronic pain or stiffness in the wrist.
• Nerve or tendon damage from the injury or treatment.
• Reduced grip strength or range of motion.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through diet and exercise to reduce fracture risk.
• Avoid falls by using assistive devices if balance is impaired.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, inability to move the wrist, or signs of infection (e.g., redness, fever). Follow up with a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the side (right wrist), fracture type (displaced), encounter type (initial), and whether the fracture is closed. Ensure clinical notes specify the pisiform bone and confirm no open wound or associated injuries to support the code.
