S62.146G Nondisplaced fracture of body of hamate [unciform] bone, unspecified wrist, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of body of hamate [unciform] bone, unspecified wrist, subsequent encounter for fracture with delayed healing

Summary

This condition refers to a break in the body of the hamate bone, one of the small carpal bones in the wrist, where the bone fragments remain in their normal alignment (nondisplaced). The hamate is located on the ulnar (pinky) side of the wrist and contributes to wrist stability and grip function. This is a subsequent encounter for a fracture with delayed healing, indicating the fracture has not healed as expected during the normal recovery period.

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

• Persistent pain, swelling, and tenderness in the ulnar 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.

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 assessments may be performed to determine the cause of delayed healing, such as blood tests or bone scans.

Treatment Options

• Immobilization: Continued use of a cast, splint, or brace to stabilize the wrist and promote healing.
• Medications: Pain relievers or anti-inflammatory drugs to manage symptoms.
• Physical Therapy: Exercises to restore range of motion and strength once healing progresses.
• Surgical Intervention: May be considered if conservative treatments fail to promote healing.

Prognosis and Follow-Up

Prognosis depends on the underlying cause of delayed healing and the effectiveness of treatment. Regular follow-up appointments with imaging studies are typically required to monitor healing progress. Most fractures eventually heal with appropriate management, though recovery may take longer than usual.

Complications

• Nonunion or malunion of the fracture.
• Chronic pain or stiffness in the wrist.
• Nerve or tendon damage in the affected area.
• Reduced grip strength or functional impairment.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or activities with a risk of wrist injury.
• Maintain bone health through a balanced diet and regular exercise.
• Follow post-injury care instructions to support healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity, or if symptoms worsen despite treatment. Contact your healthcare provider if you notice signs of infection, such as redness, warmth, or fever, or if healing does not progress as expected.

Tips for Medical Coders

This code is used for a subsequent encounter for a nondisplaced fracture of the hamate bone with delayed healing. Documentation should specify the fracture type, location, and the reason for delayed healing (e.g., poor blood supply, infection, or noncompliance with treatment). Ensure the encounter is classified as "subsequent" and that the fracture is confirmed as nondisplaced.
