S62.635P Displaced fracture of distal phalanx of left ring finger, subsequent encounter for fracture with malunion

Name of the Condition

• Displaced fracture of distal phalanx of left ring finger, subsequent encounter for fracture with malunion
• ICD Code: S62.635P

Summary

A displaced fracture of the distal phalanx of the left ring finger with malunion is a bone break at the fingertip where the fragments have shifted out of alignment and healed improperly. This subsequent encounter indicates the fracture has progressed to a stage where healing has occurred but with a malpositioned bone. Symptoms may include persistent pain, deformity, or limited function due to the misaligned bone.

Causes

This condition results from a prior traumatic injury to the left ring finger, such as a crush injury, fall, or direct blow. The initial fracture displaced the bone fragments, and during the healing process, the fragments failed to realign correctly, leading to malunion.

Risk Factors

• Delayed or inadequate initial treatment of the fracture.
• High-impact trauma that causes severe bone displacement.
• Poor blood supply to the fingertip, which can impair proper healing.
• Pre-existing conditions affecting bone healing, such as diabetes or vascular disease.

Symptoms

• Persistent pain or discomfort at the fingertip.
• Visible deformity or misalignment of the finger.
• Reduced range of motion or stiffness.
• Tenderness or swelling at the fracture site.
• Possible functional impairment, such as difficulty gripping objects.

Diagnosis

A healthcare provider will assess the finger’s alignment, mobility, and tenderness. Imaging tests, such as X-rays, are used to confirm malunion by showing the misaligned bone fragments and evaluating the extent of healing. Comparison with prior imaging may help determine the degree of displacement.

Treatment Options

• Monitoring: For mild malunion with minimal symptoms, regular follow-up may be sufficient.
• Physical Therapy: To improve range of motion and strength if stiffness or weakness is present.
• Surgical Intervention: For significant deformity or functional impairment, procedures like osteotomy (realignment of the bone) or bone grafting may be considered.
• Pain Management: Medications or other therapies to address discomfort.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and functional impact. Most patients experience improved symptoms with treatment, though some residual stiffness or deformity may persist. Follow-up visits are important to monitor healing and adjust treatment as needed.

Complications

• Chronic pain or discomfort.
• Persistent deformity affecting appearance or function.
• Reduced grip strength or dexterity.
• Increased risk of arthritis in the affected joint over time.

Lifestyle & Prevention

• Avoid re-injury to the finger during healing.
• Use protective gear during activities with hand injury risks.
• Follow rehabilitation guidelines to optimize recovery.
• Maintain overall bone health through proper nutrition and exercise.

When to Seek Professional Help

Seek care if you experience increasing pain, swelling, or deformity, or if you notice a decline in finger function. Prompt evaluation is important if symptoms worsen or do not improve with initial treatment.

Tips for Medical Coders

This code is used for a subsequent encounter for a displaced fracture of the distal phalanx of the left ring finger with malunion. Documentation should specify the malunion and confirm this is a follow-up visit for the fracture. Ensure the encounter is not an initial treatment or for a different stage of healing (e.g., nonunion).
