S66.522 Laceration of intrinsic muscle, fascia and tendon of right middle finger at wrist and hand level

Name of the Condition

• Laceration of intrinsic muscle, fascia and tendon of right middle finger at wrist and hand level
• ICD-10 Code: S66.522

Summary

This condition involves a laceration (cut or tear) of the intrinsic muscles, fascia, or tendons of the right middle finger at the wrist and hand level. Lacerations may disrupt tissue integrity, impair finger movement, and may require clinical evaluation to assess damage and guide management. The injury may affect function, stability, or sensation in the affected finger.

Causes

Lacerations typically result from acute trauma, such as cuts from sharp objects (e.g., knives, glass), falls, or direct blows to the hand. Penetrating injuries, including punctures or tears, can also damage these soft tissues. Repetitive or forceful hand movements may increase the risk of laceration in some cases.

Risk Factors

• Engaging in manual labor or activities with sharp tools.
• Participation in sports or hobbies involving hand contact (e.g., boxing, martial arts).
• Poor protective measures during high-risk tasks.
• Previous injuries to the wrist or hand that weaken tissue.

Symptoms

• Pain, swelling, or tenderness in the right middle finger.
• Visible cut or open wound at the injury site.
• Difficulty moving the finger or reduced grip strength.
• Bruising, numbness, or tingling in the affected area.
• Weakness or loss of finger function.

Diagnosis

Physical examination to assess the wound, range of motion, and sensory function is typically performed. Imaging studies, such as ultrasound or MRI, may be used to evaluate soft tissue damage. Clinical history of the injury and mechanism of trauma are also considered to guide diagnosis.

Treatment Options

Treatment may include wound cleaning, suturing, or surgical repair of damaged tissues. Immobilization with splints or casts may be necessary to promote healing. Physical therapy is often recommended to restore function and strength. Pain management and infection prevention are also key components of care.

Prognosis and Follow-Up

Prognosis depends on the extent of tissue damage and timely treatment. Most patients recover with appropriate care, though some may experience residual stiffness or weakness. Follow-up appointments are important to monitor healing and adjust treatment plans as needed.

Complications

Potential complications include infection, nerve or tendon damage, chronic pain, or reduced finger mobility. Delayed treatment or incomplete healing may increase the risk of long-term functional impairment.

Lifestyle & Prevention

Avoid activities with sharp objects or wear protective gear (e.g., gloves) during high-risk tasks. Maintain hand strength and flexibility through regular exercise. Promptly address minor injuries to prevent worsening.

When to Seek Professional Help

Seek medical attention if there is severe pain, uncontrolled bleeding, visible tissue damage, or inability to move the finger. Signs of infection, such as redness, swelling, or fever, also warrant immediate evaluation.

Tips for Medical Coders

Document the specific finger (right middle), location (wrist and hand level), and nature of the injury (laceration of intrinsic muscle, fascia, and tendon) to ensure accurate coding. Include details about the mechanism of injury and clinical findings to support the diagnosis.
