M65.20 Calcific tendinitis, unspecified site

Name of the Condition

• Calcific tendinitis, unspecified site
• Also known as calcific tendinopathy or calcium deposit tendinitis.

Summary

Calcific tendinitis is a painful condition where calcium deposits build up in the tendons, leading to inflammation and restricted movement. When the site is unspecified, it refers to calcium deposition in tendons without a designated anatomical location.

Causes

The exact cause of calcific tendinitis is not well understood, but it may be related to degenerative changes in the tendons, aging, or chronic overuse. Impaired blood flow and metabolic factors may also contribute to calcification in tendon fibers.

Risk Factors

• Age: typically occurs between 30-60 years.
• Occupations or activities involving repetitive movements.
• Previous tendon or joint issues.
• Systemic conditions affecting connective tissue.

Symptoms

• Intense pain, often worsening with movement.
• Reduced range of motion or stiffness.
• Swelling and tenderness over the affected tendon.
• A noticeable lump where the deposit has formed.

Diagnosis

Diagnosis involves a clinical 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

• Non-Surgical:
  • Rest and activity modification.
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation.
  • Physical therapy to improve mobility and strength.
  • Corticosteroid injections for severe pain.
• Surgical:
  • Procedures to remove calcium deposits may be considered for persistent symptoms.

Prognosis and Follow-Up

Most cases improve with conservative treatment, though recovery can take weeks to months. Follow-up may include monitoring for symptom recurrence or progression. Severe cases may require ongoing management.

Complications

• Chronic pain or persistent stiffness.
• Tendon rupture in rare cases.
• Reduced function if left untreated.

Lifestyle & Prevention

• Avoid repetitive stress on tendons.
• Maintain proper ergonomics during activities.
• Engage in regular, gentle stretching exercises.
• Address underlying conditions that may contribute to tendon issues.

When to Seek Professional Help

Seek care if pain is severe, mobility is significantly limited, or symptoms worsen despite rest. Prompt evaluation is recommended for sudden increases in pain or swelling.

Tips for Medical Coders

Document the site of tendinitis when specified, as this impacts code assignment. For unspecified sites, use M65.20. Ensure clinical notes support the diagnosis and exclude other causes of tendon pain.
