S62.664B Nondisplaced fracture of distal phalanx of right ring finger, initial encounter for open fracture

Name of the Condition

• Nondisplaced fracture of distal phalanx of right ring finger, initial encounter for open fracture (ICD-10 Code: S62.664B)

Summary

A nondisplaced fracture of the distal phalanx of the right ring finger, initial encounter for open fracture, is a break in the tip bone of the finger where the bone fragments remain in their normal anatomical alignment, and the fracture communicates with the external environment. This type of fracture typically involves minimal displacement, meaning the bone fragments are not shifted out of position. The distal phalanx is the most distal segment of the finger, and this injury often results from direct trauma or impact to the fingertip.

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.
• Open wound or laceration at the fracture site.

Diagnosis

Physical examination to assess pain, swelling, and deformity. Imaging studies, such as X-rays, to confirm the fracture and evaluate displacement. Assessment of the open wound for contamination or infection risk. Evaluation of nerve and tendon function to rule out associated injuries.

Treatment Options

• Wound cleaning and debridement to reduce infection risk.
• Immobilization with a splint or buddy taping to stabilize the finger.
• Pain management with analgesics or anti-inflammatory medications.
• Antibiotics may be prescribed for open fractures to prevent infection.
• Follow-up imaging to ensure proper healing and alignment.

Prognosis and Follow-Up

Most nondisplaced open fractures of the distal phalanx heal well with proper treatment. Follow-up appointments are necessary to monitor healing, remove sutures if used, and assess range of motion. Physical therapy may be recommended to restore function and strength.

Complications

• Infection at the open wound site.
• Delayed healing or nonunion.
• Stiffness or limited range of motion.
• Nerve damage leading to numbness or weakness.
• Chronic pain.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Practice proper hand safety in manual labor or sports.
• Maintain bone health through adequate nutrition and exercise.
• Avoid repetitive stress on the fingers when possible.

When to Seek Professional Help

Seek immediate medical attention for severe pain, visible deformity, open wounds, or signs of infection (e.g., redness, pus, fever). Consult a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the specific finger (right ring finger), fracture type (nondisplaced), and encounter type (initial for open fracture) to ensure accurate coding. Include details about the open wound, such as size or contamination, if available, to support the open fracture designation. Verify that the fracture is confirmed by imaging and that the initial encounter is clearly documented.
