S62.115G Nondisplaced fracture of triquetrum [cuneiform] bone, left wrist, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of triquetrum [cuneiform] bone, left wrist, subsequent encounter for fracture with delayed healing

Summary

This condition involves a break in the triquetrum bone of the left wrist without displacement of bone fragments, with delayed healing noted during a subsequent encounter. The triquetrum is a small carpal bone on the ulnar (pinky) side of the wrist, contributing to stability and movement. Nondisplaced fractures typically result from trauma, and delayed healing indicates the fracture has not progressed as expected during the healing process.

Causes

Usually caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to the wrist, or a twisting 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 triquetrum bone, which can impede healing.

Symptoms

• Persistent pain, swelling, and tenderness in the ulnar side of the left wrist.
• Bruising or discoloration around the injury site.
• Limited range of motion or difficulty moving the hand or fingers.
• Possible clicking or grinding sensations during wrist movement.

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, alignment, and healing progress. Additional assessments may include checking for signs of delayed union or nonunion.

Treatment Options

• Immobilization: Continued use of a cast, splint, or brace to stabilize the wrist and support 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: Considered if delayed healing persists or if there are complications, such as nonunion.

Prognosis and Follow-Up

Most nondisplaced fractures with delayed healing eventually heal with appropriate management, though recovery may take longer than usual. Regular follow-up appointments are necessary to monitor healing progress through imaging and clinical assessments. Full function may return, but some residual stiffness or weakness could persist.

Complications

• Prolonged pain or discomfort.
• Chronic stiffness or reduced range of motion.
• Nonunion (failure of the bone to heal).
• Arthritis in the wrist joint over time.

Lifestyle & Prevention

• Avoid high-risk activities until fully healed.
• Use protective gear during sports or activities with fall risks.
• Maintain bone health through a balanced diet and regular exercise.
• Follow medical advice for immobilization and activity restrictions.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new symptoms (e.g., numbness, tingling) develop. Contact a healthcare provider if the wrist does not improve with treatment or if there are signs of infection (e.g., redness, fever).

Tips for Medical Coders

Document the subsequent encounter for fracture with delayed healing, including clinical notes supporting the delayed healing status. Ensure the left wrist and nondisplaced nature of the fracture are clearly recorded. Code S62.115G is appropriate for this scenario when the fracture is being treated during a subsequent encounter with evidence of delayed healing.
