S62.133A Displaced fracture of capitate [os magnum] bone, unspecified wrist, initial encounter for closed fracture

Name of the Condition

• Displaced fracture of capitate [os magnum] bone, unspecified wrist, initial encounter for closed fracture

Summary

This condition involves a break in the capitate bone, one of the central carpal bones in the wrist, with displacement of the bone fragments. The capitate is the largest carpal bone and plays a key role in wrist stability and movement. Fractures in this area typically result from trauma and may vary in severity, with displaced fragments requiring specific management to restore alignment and function. This code applies to the initial encounter for a closed fracture (no open wound) of the capitate bone in an unspecified wrist.

Causes

Usually caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to the wrist, or a high-impact injury. Crushing or twisting forces 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 central wrist area.
• 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 the extent of displacement and alignment.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the area and promote healing.
• Closed reduction: Manual realignment of displaced bone fragments without surgery.
• Surgical intervention: Internal fixation (e.g., pins, screws) if fragments are severely displaced or unstable.
• Pain management: Medications to reduce discomfort during healing.
• Rehabilitation: Physical therapy to restore strength and range of motion after immobilization.

Prognosis and Follow-Up

Prognosis depends on the severity of displacement, treatment effectiveness, and adherence to rehabilitation. Most fractures heal within 6–8 weeks with proper care. Follow-up appointments monitor healing progress, and imaging may be repeated to assess bone alignment. Full recovery of wrist function is common, but some residual stiffness or weakness may persist.

Complications

• Nonunion or delayed healing of the fracture.
• Arthritis in the wrist due to joint damage.
• Nerve or tendon injury from displaced bone fragments.
• Chronic pain or reduced mobility.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports, falls).
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive wrist stress or overuse.
• Practice safe falling techniques to minimize injury risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe wrist pain, swelling, deformity, or inability to move the hand after trauma. Persistent pain, numbness, or tingling after initial treatment also warrants evaluation.

Tips for Medical Coders

This code (S62.133A) is specific to a displaced capitate fracture in an unspecified wrist, with "initial encounter" indicating the first visit for a closed fracture. Document the fracture type (displaced), wrist laterality (unspecified), encounter stage (initial), and fracture status (closed) to ensure accurate coding. Avoid using this code for open fractures, subsequent encounters, or non-displaced fractures.
