S62.111K Displaced fracture of triquetrum [cuneiform] bone, right wrist, subsequent encounter for fracture with nonunion

Name of the Condition

• Displaced fracture of triquetrum [cuneiform] bone, right wrist, subsequent encounter for fracture with nonunion

Summary

This condition involves a displaced fracture of the triquetrum bone in the right wrist, where the bone fragments have failed to heal properly (nonunion) during a subsequent encounter for treatment. The triquetrum is a small carpal bone on the ulnar (pinky) side of the wrist, and displacement means the fragments are misaligned. Nonunion indicates the fracture has not healed within the expected timeframe, potentially affecting wrist stability and function. This code is used for encounters after the initial treatment phase when healing has not progressed as intended.

Causes

Typically caused by direct trauma to the right wrist, such as a fall onto an outstretched hand, a high-impact blow, or a twisting injury. Nonunion may result from inadequate immobilization, poor blood supply to the bone, infection, or excessive movement during the healing process.

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.
• Smoking, which impairs bone healing.
• Poor nutrition or underlying medical conditions affecting bone health.

Symptoms

• Persistent pain, swelling, and tenderness in the right 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.
• Visible deformity in severe cases.

Diagnosis

Physical examination to assess pain, swelling, and mobility. Imaging tests, such as X-rays, CT scans, or MRIs, to confirm the fracture, evaluate displacement, and assess for nonunion. Additional tests may be ordered to rule out infection or other complications.

Treatment Options

• Surgical intervention: May include bone grafting, internal fixation, or other procedures to promote healing.
• Immobilization: Using a cast, splint, or brace to stabilize the wrist during recovery.
• Physical therapy: To restore strength and range of motion after healing.
• Pain management: Medications or other therapies to control discomfort.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient health, and treatment adherence. Nonunion may require extended recovery or additional interventions. Regular follow-up appointments are necessary to monitor healing and adjust treatment as needed.

Complications

• Chronic pain or stiffness in the wrist.
• Arthritis or joint damage due to improper healing.
• Nerve or tendon damage near the fracture site.
• Infection, particularly if surgery is required.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or activities with fall risks.
• Maintain bone health through proper nutrition and exercise.
• Follow post-treatment instructions carefully to support healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity, or if symptoms worsen after treatment. Contact your provider if you notice signs of infection, such as redness, warmth, or drainage at the injury site.

Tips for Medical Coders

This code is specific to a subsequent encounter for a displaced triquetrum fracture with nonunion in the right wrist. Documentation must confirm the fracture type, location, and nonunion status. Ensure the encounter is classified as "subsequent" and that nonunion is clearly documented to support code assignment.
