M65.239 Calcific tendinitis, unspecified forearm

Name of the Condition

• Calcific tendinitis, unspecified forearm
• Also known as calcific tendinopathy or calcium deposit tendinitis of the forearm.

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 forearm, it typically involves tendons around the wrist or elbow, potentially impacting grip strength and functional mobility.

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 forearm movements (e.g., typing, lifting, or sports).
• Previous tendon or joint issues in the forearm.
• Chronic conditions such as diabetes or thyroid disorders.

Symptoms

• Intense pain and tenderness in the forearm.
• Reduced range of motion or stiffness in the wrist or elbow.
• 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 aspiration to remove deposits.
• Surgical:
  • Arthroscopic or open surgery to remove large or persistent calcium deposits, typically reserved for cases unresponsive to conservative measures.

Prognosis and Follow-Up

Most cases of calcific tendinitis improve with conservative treatment, though recovery may take several months. Follow-up care often includes monitoring for symptom resolution and functional improvement. Physical therapy is commonly recommended to restore mobility and prevent recurrence.

Complications

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

Lifestyle & Prevention

• Avoid repetitive or strenuous forearm movements that may exacerbate symptoms.
• Maintain proper ergonomics during work or activities.
• Engage in regular stretching and strengthening exercises to support tendon health.
• Manage underlying conditions like diabetes to reduce risk.

When to Seek Professional Help

Seek medical attention if pain is severe, worsening, or interfering with daily activities. Prompt evaluation is recommended if symptoms do not improve with rest or over-the-counter treatments, or if there is noticeable swelling, warmth, or a lump in the forearm.

Tips for Medical Coders

Use this code for documentation of calcific tendinitis affecting the forearm when the specific side (left or right) is not specified. Ensure clinical notes support the diagnosis, including details of symptoms, physical exam findings, and imaging results if available. Verify that the condition is not better described by a more specific code (e.g., for a specified forearm side) before applying this unspecified code.
