M65.28 Calcific tendinitis, other site

Name of the Condition

• Calcific tendinitis, other site
• Also known as calcific tendinopathy or calcium deposit tendinitis of other anatomical sites.

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 other sites, it refers to calcium deposition in tendons outside of commonly specified locations (e.g., shoulder, upper arm).

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 movements of the affected area.
• Previous tendon or joint issues.
• Chronic conditions such as diabetes.

Symptoms

• Intense pain and tenderness in the affected area.
• Reduced range of motion or stiffness.
• 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) for pain and inflammation.
  • Physical therapy to improve range of motion and strength.
  • Ultrasound-guided needle lavage or steroid injections in some cases.
• Surgical:
  • Arthroscopic removal of calcium deposits if conservative measures fail.

Prognosis and Follow-Up

Most cases improve with conservative treatment, though recovery may take weeks to months. Follow-up may include monitoring for symptom resolution and functional improvement. Recurrence is possible, especially with persistent risk factors.

Complications

• Chronic pain or persistent stiffness.
• Tendon rupture (rare).
• Nerve compression if deposits press on nearby structures.

Lifestyle & Prevention

• Avoid repetitive movements that strain the affected tendon.
• Maintain strength and flexibility through regular exercise.
• Use proper ergonomics during activities or work.
• Manage underlying conditions like diabetes to reduce risk.

When to Seek Professional Help

Seek care if pain is severe, worsening, or limits daily activities; if swelling or redness develops; or if movement becomes significantly restricted.

Tips for Medical Coders

Document the specific anatomical site of calcific tendinitis (e.g., wrist, hip) to support the use of M65.28. Include details on imaging findings, clinical presentation, and treatment approaches to ensure accurate code assignment and clinical correlation.
