S62.657K Nondisplaced fracture of middle phalanx of left little finger, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of middle phalanx of left little finger, subsequent encounter for fracture with nonunion (ICD-10 Code: S62.657K)

Summary

A nondisplaced fracture of the middle phalanx of the left little finger, subsequent encounter for fracture with nonunion, refers to a break in the middle bone segment of the left little finger where the bone fragments remain in their normal anatomical alignment, but the fracture has failed to heal properly (nonunion) during a follow-up visit. This condition indicates that the bone has not united after an initial injury, requiring ongoing management. The fracture is classified as subsequent because it is being addressed after prior treatment, and the nonunion signifies a delay or absence of healing.

Causes

Direct trauma or impact to the left little finger, such as from falls, sports injuries, or accidents, is the primary cause. Crushing injuries or severe bending forces applied to the finger can also result in this fracture. Factors contributing to nonunion may include inadequate immobilization, poor blood supply to the bone, infection, or underlying conditions that impair healing.

Risk Factors

• Participation in contact sports or activities with a high risk of hand injuries.
• Occupations involving manual labor or repetitive hand use.
• Prior history of hand or finger fractures, especially those with delayed healing.
• Conditions that weaken bone density, such as osteoporosis or diabetes.
• Smoking or other lifestyle factors that impair bone healing.

Symptoms

• Persistent pain, swelling, or tenderness at the fracture site.
• Limited range of motion or difficulty moving the finger.
• Visible or palpable gap at the fracture site (in some cases).
• No improvement in symptoms despite prior treatment.

Diagnosis

Diagnosis involves a physical examination to assess pain, swelling, and range of motion. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture and evaluate for nonunion. The provider will review the patient’s medical history, including prior treatments and the timeline of healing, to determine if the fracture has failed to unite. Additional tests may be ordered to rule out infection or assess bone health.

Treatment Options

Treatment focuses on promoting bone healing and may include immobilization with a splint or cast to stabilize the finger. Surgical intervention, such as bone grafting or internal fixation, may be necessary if nonunion persists. Physical therapy is often recommended to restore function and strength. Pain management and monitoring for complications are also part of the care plan.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and the effectiveness of treatment. With appropriate management, many patients achieve healing and improved function, but recovery may be prolonged. Regular follow-up appointments are essential to monitor healing progress, adjust treatment, and address any complications. Long-term outcomes vary based on individual factors, including age and overall health.

Complications

• Chronic pain or discomfort.
• Persistent limited range of motion.
• Infection, particularly if surgical intervention is required.
• Need for additional surgeries if nonunion does not resolve.
• Long-term functional impairment of the finger.

Lifestyle & Prevention

• Avoid activities that risk finger injury, such as contact sports or heavy lifting, until healed.
• Use protective gear (e.g., gloves) during high-risk tasks.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Follow post-treatment instructions carefully to promote healing.
• Quit smoking, as it can impair bone healing.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, swelling, or difficulty moving the finger, or if symptoms do not improve with initial treatment. Prompt evaluation is important if you notice a gap at the fracture site or signs of infection, such as redness, warmth, or drainage.

Tips for Medical Coders

Document the subsequent encounter for fracture with nonunion clearly, including details about the fracture’s location (middle phalanx of left little finger) and the failure to heal. Ensure the record specifies the nonunion and confirms this is a follow-up visit. Code S62.657K is appropriate when the fracture is nondisplaced, involves the left little finger, and is being addressed during a subsequent encounter with evidence of nonunion.
