S86.091 Other specified injury of right Achilles tendon

Name of the Condition

• Other specified injury of right Achilles tendon
• ICD-10 Code: S86.091

Summary

The other specified injury of the right Achilles tendon refers to damage to the tendon connecting the calf muscles to the heel bone, with the injury type specified but not classified under more detailed categories. This condition typically results from trauma or overuse and requires evaluation to determine the extent of damage and guide management.

Causes

Sudden forceful movements, such as jumping or sprinting. Direct trauma to the tendon. Repetitive stress from activities like running or dancing. Aging-related tendon degeneration.

Risk Factors

• Participation in high-impact sports (e.g., basketball, soccer)
• Poor calf muscle flexibility or strength
• Inadequate warm-up before exercise
• Previous Achilles tendon injuries
• Certain medications (e.g., fluoroquinolones)

Symptoms

• Sharp pain in the back of the right ankle or heel
• Swelling, bruising, or tenderness along the tendon
• Difficulty pointing the foot downward or standing on tiptoe
• Audible "pop" or snap at the time of injury (in severe cases)

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Patient history review focusing on activity and injury details. Imaging tests (e.g., MRI, ultrasound) to visualize tendon integrity.

Treatment Options

• Rest and immobilization (e.g., casting or walking boot)
• Ice application to reduce swelling
• Physical therapy to restore strength and flexibility
• Surgical repair in severe cases

Prognosis and Follow-Up

With proper treatment, most tendon injuries heal within weeks or months. Regular follow-up to monitor healing and adjust therapy as needed is important for optimal recovery.

Complications

• Chronic pain or stiffness
• Re-rupture of the tendon
• Limited mobility or function
• Nerve damage in severe cases

Lifestyle & Prevention

• Warm up properly before physical activity
• Strengthen calf muscles through targeted exercises
• Wear supportive footwear
• Avoid sudden increases in activity intensity
• Maintain a healthy weight to reduce tendon stress

When to Seek Professional Help

Seek medical attention if pain is severe, swelling worsens, or mobility is significantly impaired. Prompt evaluation is recommended for suspected tendon tears or persistent symptoms.

Tips for Medical Coders

Document the specific nature of the injury (e.g., partial tear, contusion) and laterality (right) to support accurate coding. Include details about the mechanism of injury and clinical findings to justify the use of S86.091. Ensure documentation aligns with the specified injury type to avoid miscoding.
