S62.165B Nondisplaced fracture of pisiform, left wrist, initial encounter for open fracture

Name of the Condition

• Nondisplaced fracture of pisiform, left wrist, initial encounter for open fracture

Summary

This condition describes a break in the pisiform bone of the left wrist where the bone fragments remain in their normal position (nondisplaced) and the fracture is open (exposing the bone to the external environment). The pisiform is a small, pea-shaped carpal bone on the palmar (palm) side of the wrist, embedded within the flexor carpi ulnaris tendon. Open fractures require prompt medical attention due to the risk of infection and typically result from trauma.

Causes

Typically caused by direct trauma to the left wrist, such as a fall onto an outstretched hand, a blow to the palmar side, or a crushing injury. High-impact events or accidents may lead to this specific 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 left wrist.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the hand or fingers.
• Visible wound or open area at the fracture site (for open fractures).

Diagnosis

Physical examination to assess pain, swelling, and wrist mobility. Imaging tests, such as X-rays, to confirm the fracture and evaluate its extent and alignment. The open nature of the fracture is determined by clinical assessment of the wound.

Treatment Options

• Wound care: Cleaning and dressing the open fracture to prevent infection.
• Immobilization: Using a cast or splint to stabilize the wrist.
• Antibiotics: Administered to reduce infection risk in open fractures.
• Surgical intervention: May be required for severe cases or if the fracture does not heal properly.

Prognosis and Follow-Up

With proper treatment, most nondisplaced fractures heal well. Follow-up appointments monitor healing progress, and physical therapy may be recommended to restore function. Open fractures require closer monitoring for infection.

Complications

• Infection at the fracture site.
• Delayed healing or nonunion.
• Limited wrist mobility or stiffness.
• Nerve or tendon damage (rare).

Lifestyle & Prevention

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

When to Seek Professional Help

Seek immediate care if there is severe pain, visible bone exposure, or signs of infection (e.g., redness, pus, fever).

Tips for Medical Coders

Document the fracture as nondisplaced, left-sided, and open, with an initial encounter. Include details about the wound (e.g., size, contamination) and any associated injuries. Ensure the code reflects the open nature of the fracture and the initial phase of treatment.
