S86.02 Laceration of Achilles tendon

Name of the Condition

• Laceration of Achilles tendon
• ICD-10 Code: S86.02

Summary

The laceration of the Achilles tendon refers to a cut or tear in the thick tendon connecting the calf muscles to the heel bone. This injury typically results from direct trauma and may involve partial or complete disruption of the tendon, affecting mobility and requiring prompt medical evaluation to determine the extent of damage and guide treatment.

Causes

Direct trauma to the tendon, such as a sharp object or forceful impact. Penetrating injuries or lacerations from accidents or falls. Surgical or procedural complications involving the tendon.

Risk Factors

• Participation in activities with high risk of direct trauma (e.g., contact sports, industrial work)
• Previous Achilles tendon injuries or surgeries
• Poor protective equipment or footwear
• Certain medical conditions affecting tissue integrity (e.g., diabetes, vascular disease)

Symptoms

• Visible cut or tear in the tendon area
• Sudden pain and swelling at the injury site
• Difficulty pointing the foot downward or standing on tiptoe
• Audible "pop" or snap at the time of injury (if traumatic)
• Bruising or bleeding around the heel

Diagnosis

Physical examination to assess the wound, pain, and range of motion. Patient history review focusing on the mechanism of injury. Imaging tests (e.g., MRI, ultrasound) to evaluate tendon integrity and rule out additional damage.

Treatment Options

• Wound cleaning and debridement to prevent infection
• Surgical repair of the tendon in most cases
• Immobilization (e.g., casting or walking boot) to allow healing
• Physical therapy to restore strength and flexibility after recovery

Prognosis and Follow-Up

With timely surgical repair and rehabilitation, most patients regain function within months. Follow-up appointments monitor healing, range of motion, and strength. Complications like infection or re-rupture may require additional intervention.

Complications

• Infection at the wound site
• Tendon re-rupture or weakness
• Chronic pain or stiffness
• Nerve or vascular damage from the injury
• Delayed healing due to poor blood supply

Lifestyle & Prevention

• Wear protective gear during high-risk activities
• Use proper footwear with adequate support
• Avoid sudden, forceful movements that strain the tendon
• Maintain calf muscle strength and flexibility through regular exercise

When to Seek Professional Help

Seek immediate medical attention if a cut or tear is visible, pain is severe, or mobility is significantly impaired. Prompt evaluation reduces the risk of complications and improves outcomes.

Tips for Medical Coders

Document the mechanism of injury (e.g., laceration, penetrating trauma) and any associated complications. Ensure the wound is described as open or closed, and note if surgical repair was performed. Include details on imaging or diagnostic findings to support the diagnosis.
