M65.27 Calcific tendinitis, ankle and foot

Name of the Condition

• Calcific tendinitis, ankle and foot
• Also known as calcific tendonitis or tendinopathy due to calcification in the ankle and foot region.

Summary

Calcific tendinitis is a condition characterized by the buildup of calcium deposits in the tendons of the ankle and foot. This can lead to pain, inflammation, and restricted movement, commonly affecting individuals without a specific prior injury.

Causes

The exact cause of calcific tendinitis is not well understood. It is thought to involve a combination of factors, including overuse of the tendons, age-related changes, and impaired blood flow leading to calcification in the tendon fibers.

Risk Factors

• Age: Commonly affects people aged 30-60.
• Occupations or activities involving repetitive movement of the ankle or foot.
• Trauma or injury to the foot or ankle area.
• Preexisting conditions such as diabetes.

Symptoms

• Intense pain and tenderness in the affected ankle or foot.
• Limited range of motion and stiffness.
• Swelling and redness in the area.
• A noticeable lump where the deposit has formed.

Diagnosis

Diagnosis typically involves a physical examination to assess pain and mobility. Imaging tests, such as X-rays or ultrasound, are used to visualize calcium deposits. MRI may be employed for detailed tendon evaluation if needed.

Treatment Options

• Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation.
• Physical therapy to improve range of motion and strengthen surrounding muscles.
• Corticosteroid injections for severe pain or inflammation.
• Extracorporeal shock wave therapy to break up calcium deposits.
• Surgical intervention in rare cases where conservative treatments fail.

Prognosis and Follow-Up

Most cases of calcific tendinitis improve with conservative treatment, though recovery may take several weeks to months. Follow-up care often includes monitoring for symptom resolution and functional improvement. Recurrence is possible, especially with continued overuse or inadequate rest.

Complications

• Chronic pain or persistent stiffness if untreated.
• Tendon rupture in severe cases.
• Reduced mobility or functional impairment affecting daily activities.

Lifestyle & Prevention

• Avoid repetitive or high-impact activities that strain the ankle and foot.
• Use proper footwear and ergonomic support during activities.
• Maintain a healthy weight to reduce stress on tendons.
• Incorporate stretching and strengthening exercises to support tendon health.

When to Seek Professional Help

Seek medical attention if pain is severe, worsening, or accompanied by significant swelling, redness, or inability to bear weight. Prompt evaluation is recommended if symptoms do not improve with rest or over-the-counter treatments.

Tips for Medical Coders

Document the specific anatomical location (ankle and foot) to support the use of M65.27. Include details on the affected tendon(s) and any imaging findings confirming calcification. Ensure clinical notes align with the diagnosis to justify code assignment.
