S62.651A Nondisplaced fracture of middle phalanx of left index finger, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of middle phalanx of left index finger, initial encounter for closed fracture (ICD-10 Code: S62.651A)

Summary

A nondisplaced fracture of the middle phalanx of the left index finger is a break in the middle bone segment of the index finger where the bone fragments remain in their normal anatomical alignment. This is an initial encounter for a closed fracture, meaning the skin is intact and the fracture has not pierced through the skin. The condition involves the middle phalanx, which is the central bone of the finger, and is specific to the left index finger.

Causes

Direct trauma or impact to the finger, such as from falls, sports injuries, or accidents. Crushing injuries or severe bending forces applied to the finger can also cause this type of fracture. The injury typically results from a sudden force that breaks the bone without displacing the fragments.

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 in the affected finger.
• Bruising around the injury site.
• Limited range of motion or inability to move the finger normally.
• Possible 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.

Treatment Options

• Immobilization with a splint or cast to stabilize the finger and promote healing.
• Pain management with over-the-counter or prescription medications.
• Physical therapy to restore range of motion and strength after healing.
• Surgical intervention is rarely needed for nondisplaced fractures unless instability is present.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with proper immobilization and care. Follow-up appointments are typically scheduled to monitor healing progress, often with repeat imaging to confirm bone alignment. Full recovery may take several weeks, with gradual return to normal activities as tolerated.

Complications

• Delayed healing or nonunion if the fracture does not heal properly.
• Stiffness or reduced range of motion in the finger.
• Chronic pain or discomfort.
• Nerve or tendon damage, though rare in nondisplaced fractures.

Lifestyle & Prevention

• Use protective gear during sports or activities with hand injury risks.
• Avoid repetitive or forceful finger movements that may increase injury risk.
• Maintain bone health through adequate calcium and vitamin D intake.
• Practice proper ergonomics in manual labor or repetitive tasks.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, inability to move the finger, visible deformity, or signs of infection (e.g., redness, pus, fever). Follow up with a healthcare provider if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

Document the specific finger (left index), fracture type (nondisplaced), and encounter details (initial, closed) to ensure accurate coding. Include clinical notes confirming the fracture's alignment and skin integrity to support the diagnosis.
