S62.66 Nondisplaced fracture of distal phalanx of finger

Name of the Condition

• Nondisplaced fracture of distal phalanx of finger (ICD-10 Code: S62.66)

Summary

A nondisplaced fracture of the distal phalanx of a finger is a break in the tip bone of the finger where the bone fragments remain in their normal anatomical alignment. This type of fracture typically involves minimal displacement, meaning the bone does not shift out of place. It is a common injury affecting the distal phalanx, the most distal bone segment of the finger.

Causes

Direct trauma or impact to the fingertip, such as from crushing injuries, falls, or accidents. Severe bending forces applied to the finger, often seen in sports or manual labor, can also cause this fracture. Repetitive stress or overuse is less common but may contribute in some cases.

Risk Factors

• Participation in contact sports or activities with a high risk of hand injuries.
• Occupations involving manual labor or handling heavy equipment.
• Prior history of hand or finger fractures.
• Osteoporosis or other conditions that weaken bone density.

Symptoms

• Pain, swelling, and tenderness at the fingertip.
• Bruising around the injury site.
• Possible deformity or misalignment, though less pronounced than in displaced fractures.
• Limited range of motion or difficulty moving the fingertip.
• Numbness or tingling if nerves are involved.

Diagnosis

Physical examination by a healthcare professional to assess pain, swelling, and mobility. Imaging tests, such as X-rays, to confirm the fracture and rule out other injuries. Clinical evaluation focuses on determining the extent of the fracture and whether displacement is present.

Treatment Options

• Immobilization with a splint or buddy taping to adjacent fingers to maintain alignment during healing.
• Pain management with over-the-counter or prescription medications.
• Closed reduction (realignment of bone fragments) if minimal displacement is present.
• Surgery is rarely required for nondisplaced fractures but may be considered if instability is noted.

Prognosis and Follow-Up

Most nondisplaced fractures of the distal phalanx heal well with conservative treatment. Recovery typically takes 4–6 weeks, depending on the severity. Follow-up appointments may be scheduled to monitor healing and assess range of motion. Physical therapy may be recommended to restore function if stiffness occurs.

Complications

• Stiffness or reduced range of motion in the finger.
• Chronic pain or sensitivity at the injury site.
• Infection, particularly if the fracture is open (exposed to the skin).
• Delayed union or nonunion of the bone, though rare in nondisplaced cases.

Lifestyle & Prevention

• Use protective gear, such as gloves, during activities with a high risk of hand injuries.
• Avoid repetitive or forceful finger movements that may increase injury risk.
• Maintain bone health through a balanced diet and regular exercise to support healing.
• Practice proper hand ergonomics in work or daily tasks to reduce strain.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, visible deformity, or an open wound. Contact a healthcare provider if symptoms worsen, or if there is numbness, tingling, or difficulty moving the finger after an injury.

Tips for Medical Coders

Document the specific location (distal phalanx) and confirm that the fracture is nondisplaced to support accurate coding. Ensure clinical documentation aligns with the ICD-10-CM code S62.66, as this code is specific to the distal phalanx and requires clear evidence of nondisplacement. Verify that no other finger or phalanx is involved unless separately documented.
