S62.165D Nondisplaced fracture of pisiform, left wrist, subsequent encounter for fracture with routine healing

Name of the Condition

• Nondisplaced fracture of pisiform, left wrist, subsequent encounter for fracture with routine healing

Summary

This condition describes a break in the pisiform bone of the left wrist where the bone fragments remain in their normal anatomical position, and the fracture is in the healing phase with expected progress. The pisiform is a small, pea-shaped carpal bone on the palmar (palm) side of the wrist, embedded within the flexor carpi ulnaris tendon. Nondisplaced fractures typically result from trauma and are characterized by the absence of bone fragment displacement, which helps preserve wrist stability and function during healing.

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 left 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. Documentation should indicate the fracture is healing as expected without complications.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the wrist and promote healing.
• Pain management: Over-the-counter or prescription medications to reduce discomfort.
• Physical therapy: Exercises to restore strength and range of motion once healing progresses.
• Monitoring: Regular follow-up to assess healing and adjust treatment as needed.

Prognosis and Follow-Up

With proper treatment, most nondisplaced fractures of the pisiform heal well, and patients can expect a full recovery of wrist function. Follow-up appointments are important to monitor healing progress and ensure no complications arise. Recovery time varies but typically ranges from several weeks to a few months, depending on the individual and injury severity.

Complications

• Delayed healing or nonunion if the fracture does not heal properly.
• Arthritis in the wrist joint over time.
• Nerve or tendon irritation due to swelling or scar tissue.
• Reduced wrist mobility or strength if rehabilitation is incomplete.

Lifestyle & Prevention

• Avoid high-risk activities or use protective gear during sports.
• Maintain bone health through a balanced diet and regular exercise.
• Use proper techniques to prevent falls, such as wearing appropriate footwear.
• Strengthen wrist muscles through targeted exercises to improve stability.

When to Seek Professional Help

Seek medical attention if you experience severe pain, swelling, or deformity after a wrist injury. Contact a healthcare provider if symptoms worsen, or if you notice numbness, tingling, or difficulty moving the hand or fingers, as these may indicate complications.

Tips for Medical Coders

This code is used for a nondisplaced fracture of the pisiform in the left wrist during a subsequent encounter for fracture with routine healing. Documentation should specify the fracture type (nondisplaced), location (left wrist), and healing status (routine). Ensure the encounter note confirms the fracture is healing as expected without complications to support accurate coding.
