S62.166A Nondisplaced fracture of pisiform, unspecified wrist, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of pisiform, unspecified wrist, initial encounter for closed fracture

Summary

This condition refers to a break in the pisiform bone of the wrist where the bone fragments remain in their normal position (nondisplaced) and the fracture is closed (skin intact). The pisiform is a small, pea-shaped carpal bone located on the palmar (palm) side of the wrist, embedded within the flexor carpi ulnaris tendon. Fractures in this area typically result from trauma and may vary in severity, with nondisplacement indicating a less severe injury. This code is used for the initial encounter of a closed fracture.

Causes

Typically caused by direct trauma to the 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 fractures in this specific bone.

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 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 and evaluate its extent and alignment.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the wrist and allow healing.
• Pain management: Over-the-counter or prescription medications to reduce pain and inflammation.
• Physical therapy: Exercises to restore strength and range of motion once healing progresses.
• Surgery: Rarely required for nondisplaced fractures, but may be considered if displacement occurs or if other complications arise.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and rest. Follow-up appointments are typically scheduled to monitor healing and adjust treatment as needed. Full recovery may take several weeks to months, depending on the individual and the severity of the injury.

Complications

• Delayed healing or nonunion of the fracture.
• Chronic pain or stiffness in the wrist.
• Nerve or tendon damage in severe cases.
• Post-traumatic arthritis if the fracture affects joint alignment.

Lifestyle & Prevention

• Wear protective gear during high-risk activities (e.g., sports, manual labor).
• Maintain bone health through a balanced diet and regular exercise.
• Avoid falls by using assistive devices if needed, especially in older adults.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after a wrist injury, or if symptoms worsen despite home care.

Tips for Medical Coders

Use this code for the initial encounter of a closed, nondisplaced fracture of the pisiform bone in the unspecified wrist. Document the fracture type (nondisplaced), encounter stage (initial), and whether the fracture is open or closed (closed) to support accurate coding. Ensure the wrist side (unspecified) is documented if not specified in the record.
