S62.653P Nondisplaced fracture of middle phalanx of left middle finger, subsequent encounter for fracture with malunion

Name of the Condition

• Nondisplaced fracture of middle phalanx of left middle finger, subsequent encounter for fracture with malunion (ICD-10 Code: S62.653P)

Summary

A nondisplaced fracture of the middle phalanx of the left middle finger, subsequent encounter for fracture with malunion, refers to a break in the middle bone segment of the left middle finger where the bone fragments remain in their normal anatomical alignment, but healing has occurred with abnormal bone alignment. This condition is classified as a subsequent encounter, indicating the fracture has been previously treated, and malunion denotes incomplete or improper healing that affects the bone’s structure or function.

Causes

Direct trauma or impact to the finger, such as from falls, sports injuries, or accidents, can lead to this fracture. Malunion may develop if the initial fracture was not properly aligned during healing, or if the bone did not heal in its original position due to inadequate immobilization or other factors.

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.
• Inadequate immobilization or non-compliance with treatment during initial fracture healing.

Symptoms

• Pain, swelling, and tenderness in the affected finger.
• Bruising around the injury site.
• Limited range of motion or difficulty moving the finger.
• Visible or palpable deformity due to malunion.
• Stiffness or discomfort with movement.

Diagnosis

Diagnosis involves a physical examination to assess range of motion, swelling, and deformity. Imaging studies, such as X-rays, are used to confirm the fracture and evaluate bone alignment. The provider will review the patient’s history, including prior treatment and healing progress, to determine if malunion is present. Additional imaging, like CT scans, may be used to assess the extent of malunion.

Treatment Options

Treatment focuses on managing symptoms and addressing functional impairment. Options may include physical therapy to improve range of motion and strength, orthotic devices or splints for support, and pain management. In severe cases, surgical intervention to realign the bone (osteotomy) may be considered to correct malunion and restore function.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and the patient’s response to treatment. Most patients experience improved function with conservative management, though some may have persistent stiffness or discomfort. Regular follow-up appointments are necessary to monitor healing, assess range of motion, and adjust treatment plans as needed.

Complications

• Chronic pain or discomfort.
• Persistent limited range of motion.
• Increased risk of future fractures due to altered bone structure.
• Nerve or tendon irritation from malaligned bone.
• Aesthetic concerns related to deformity.

Lifestyle & Prevention

• Use protective gear during high-risk activities (e.g., sports).
• Practice proper ergonomics and technique in manual labor to reduce injury risk.
• Ensure prompt and appropriate treatment for initial fractures to minimize malunion risk.
• Engage in regular hand exercises to maintain flexibility and strength.

When to Seek Professional Help

Seek medical attention if you experience worsening pain, swelling, or deformity, or if you notice a decrease in finger function. Prompt evaluation is important if symptoms do not improve with conservative measures or if you suspect malunion.

Tips for Medical Coders

This code is used for a subsequent encounter for a nondisplaced fracture of the middle phalanx of the left middle finger with malunion. Documentation should specify the fracture type (nondisplaced), location (left middle finger, middle phalanx), encounter type (subsequent), and the presence of malunion. Ensure the record includes details about prior treatment and healing status to support the malunion diagnosis.
