S62.144A Nondisplaced fracture of body of hamate [unciform] bone, right wrist, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of body of hamate [unciform] bone, right wrist, initial encounter for closed fracture

Summary

This condition refers to a break in the body of the hamate bone, one of the small carpal bones in the right wrist, where the bone fragments remain in their normal alignment. The hamate is located on the ulnar (pinky) side of the wrist and plays a role in wrist stability and grip function. Fractures in this area typically result from trauma and are classified as closed (no open wound) and nondisplaced (no misalignment of fragments). This code is used for the initial encounter of such a fracture.

Causes

Typically caused by direct trauma to the wrist, such as a fall onto an outstretched hand, a blow to 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 ulnar side of the right 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. The diagnosis confirms a nondisplaced, closed fracture of the hamate bone in the right wrist.

Treatment Options

• Immobilization: Using a cast, splint, or brace to stabilize the wrist and allow healing.
• Pain management: Medications to reduce pain and inflammation.
• Physical therapy: Exercises to restore strength and mobility once healing progresses.
• Surgery: Rarely required for nondisplaced fractures, but may be considered if displacement occurs or if conservative treatment fails.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with immobilization and time. Full recovery may take several weeks to months, depending on the severity and adherence to treatment. Follow-up appointments monitor healing and adjust care as needed. Long-term outcomes are generally favorable with proper management.

Complications

• Delayed healing or nonunion of the fracture.
• Chronic pain or stiffness in the wrist.
• Nerve or tendon irritation due to swelling or misalignment.
• Post-traumatic arthritis in the wrist joint.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Maintain bone health through diet and exercise to reduce fracture risk.
• Avoid falls by using proper safety measures (e.g., handrails, non-slip surfaces).

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after a wrist injury. Consult a healthcare provider if symptoms worsen or do not improve with initial care.

Tips for Medical Coders

Use this code for the initial encounter of a nondisplaced, closed fracture of the hamate bone in the right wrist. Document the absence of displacement and the closed nature of the fracture to support code assignment. Ensure the encounter is classified as initial (not subsequent or sequela) and specify the right wrist.
