S62.166G Nondisplaced fracture of pisiform, unspecified wrist, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of pisiform, unspecified wrist, subsequent encounter for fracture with delayed healing

Summary

This condition refers to a break in the pisiform bone of the wrist where the bone fragments remain in their normal anatomical position, and the fracture is classified as having delayed healing during a subsequent encounter. 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. Nondisplaced fractures typically result from trauma and may involve minimal disruption to surrounding structures, preserving wrist stability and function. Delayed healing indicates that the fracture has not progressed as expected during the healing process.

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.
• Poor blood supply to the pisiform bone, which can impede healing.

Symptoms

• Persistent 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 (rare with nondisplaced fractures).
• Prolonged healing time compared to typical fracture recovery.

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. Additional imaging may be used to assess healing progress and identify signs of delayed union.

Treatment Options

• Immobilization: Continued use of a cast or splint to stabilize the wrist and promote healing.
• Medications: Pain relievers or anti-inflammatory drugs to manage discomfort.
• Physical Therapy: Exercises to restore range of motion and strength once healing allows.
• Surgical Intervention: Rarely required for nondisplaced fractures but may be considered if healing does not progress.

Prognosis and Follow-Up

Most nondisplaced fractures of the pisiform heal with proper immobilization and care, though delayed healing may extend recovery time. Regular follow-up appointments are necessary to monitor healing progress. Full recovery of wrist function is typically expected, but the timeline may be longer than for fractures with normal healing.

Complications

• Prolonged pain or discomfort.
• Reduced wrist mobility or strength.
• Nonunion (failure of the fracture to heal) in severe cases.
• Arthritis or chronic wrist pain if the fracture affects joint alignment.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or activities with a fall risk.
• Maintain bone health through a balanced diet and regular exercise.
• Seek prompt treatment for wrist injuries to support proper healing.

When to Seek Professional Help

• Persistent or worsening pain, swelling, or bruising.
• Inability to move the wrist or fingers.
• Signs of infection, such as redness, warmth, or fever.
• Delayed healing concerns based on follow-up imaging.

Tips for Medical Coders

This code is used for a subsequent encounter of a nondisplaced pisiform fracture with delayed healing. Documentation should specify the fracture type (nondisplaced), the affected wrist (unspecified), and the reason for the encounter (delayed healing). Ensure the medical record supports the diagnosis and the need for ongoing care related to the healing process.
