M65.261 Calcific tendinitis, right lower leg

Name of the Condition

• Calcific tendinitis, right lower leg
• Also known as calcific tendinopathy or calcium deposit tendinitis of the right lower leg.

Summary

Calcific tendinitis is a condition characterized by the buildup of calcium deposits in the tendons, leading to pain, inflammation, and restricted movement. When it affects the right lower leg, it typically involves tendons around the knee or ankle, potentially impacting mobility and function.

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: Typically occurs between 30-60 years.
• Occupations or activities requiring repetitive lower leg movements.
• Previous tendon or joint issues.
• Chronic conditions such as diabetes.

Symptoms

• Intense pain and tenderness in the right lower leg.
• Reduced range of motion or stiffness in the knee or ankle.
• Swelling and warmth over the affected tendon.
• 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.

Treatment Options

• Non-Surgical:
  • Rest and activity modification.
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation.
  • Physical therapy to improve range of motion and strength.
  • Ultrasound-guided needle lavage or steroid injections for severe cases.
• Surgical:
  • Arthroscopic removal of calcium deposits if conservative treatments fail.

Prognosis and Follow-Up

Most cases of calcific tendinitis improve with conservative treatment, though recovery may take weeks to months. Follow-up care often includes monitoring for symptom resolution and gradual return to activity. Severe or persistent cases may require ongoing management.

Complications

• Chronic pain or stiffness if untreated.
• Tendon rupture in rare cases.
• Recurrence of calcium deposits.

Lifestyle & Prevention

• Avoid repetitive or high-impact activities that strain the lower leg.
• Maintain flexibility and strength through regular exercise.
• Use proper footwear and ergonomic support during activities.

When to Seek Professional Help

Seek medical attention if pain is severe, worsening, or accompanied by 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 (right lower leg) and any associated symptoms or treatments. Ensure clinical notes support the diagnosis and specify the affected tendon or joint area for accurate coding.
