S62.355A Nondisplaced fracture of shaft of fourth metacarpal bone, left hand, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of shaft of fourth metacarpal bone, left hand, initial encounter for closed fracture

Summary

A nondisplaced fracture of the shaft of the fourth metacarpal bone in the left hand refers to a break in the midsection of the bone that connects the ring finger to the wrist, where the bone fragments remain aligned. This injury typically results from trauma or impact to the hand and does not involve significant displacement of the bone fragments. The term "initial encounter for closed fracture" indicates this is the first episode of care for a fracture that does not penetrate the skin.

Causes

Direct trauma, such as a fall or blow to the hand. Sports-related injuries or accidents. Repetitive stress or overuse.

Risk Factors

• Participation in contact sports or high-impact activities.
• Reduced bone density or osteoporosis.
• Occupational hazards involving manual labor.

Symptoms

• Pain and swelling in the hand.
• Tenderness or bruising around the affected area.
• Difficulty moving the fingers or hand.
• Possible deformity or misalignment (less common with nondisplaced fractures).

Diagnosis

Physical examination by a healthcare provider to assess tenderness, swelling, or deformity. Imaging tests, such as X-rays, to confirm the fracture and evaluate its extent.

Treatment Options

• Immobilization with a cast or splint to promote healing.
• Pain management using over-the-counter or prescription medications.
• Physical therapy to restore mobility and strength.
• Surgery may be required for severe or displaced fractures to realign the bone.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment. Follow-up care typically includes monitoring for proper healing and assessing functional recovery. Physical therapy may be recommended to restore strength and range of motion. Healing time varies but generally ranges from 4 to 6 weeks.

Complications

• Delayed healing or nonunion.
• Malunion (healing in an abnormal position).
• Chronic pain or stiffness.
• Nerve or tendon injury (rare).

Lifestyle & Prevention

• Use protective gear during sports or high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid repetitive hand stress or overuse.
• Practice proper ergonomics during manual labor.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, swelling, or deformity, or if the hand cannot be moved. Also, consult a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the specific metacarpal bone (fourth), hand (left), and encounter type (initial for closed fracture) to ensure accurate coding. Include details about the fracture's alignment and whether the skin was intact to support the "closed" classification. Note any associated injuries or comorbidities that may affect coding specificity.
