M65.23 Calcific tendinitis, forearm

Name of the Condition

• Calcific tendinitis, 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 if needed.

Treatment Options

• Non-Surgical:
  • Rest and activity modification.
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) for pain relief.
  • Physical therapy to improve range of motion and strength.
  • Ultrasound-guided needle lavage or steroid injections for persistent cases.
• Surgical:
  • Arthroscopic or open surgery to remove large deposits if conservative measures fail.

Prognosis and Follow-Up

Most cases resolve with conservative treatment, though recovery may take weeks to months. Follow-up may include monitoring for recurrence and assessing functional improvement. Surgical outcomes are generally good, but recovery time is longer.

Complications

• Chronic pain or persistent stiffness.
• Tendon rupture (rare).
• Recurrence of calcium deposits.
• Reduced grip strength or mobility if untreated.

Lifestyle & Prevention

• Avoid repetitive forearm movements or use ergonomic tools.
• Maintain strength and flexibility through regular exercise.
• Apply ice and rest after overuse.
• Address underlying conditions like diabetes to reduce risk.

When to Seek Professional Help

Seek care if pain is severe, worsens, or limits daily activities. Prompt evaluation is recommended if swelling, redness, or a lump develops, as these may indicate infection or other issues.

Tips for Medical Coders

Document the specific anatomical site (forearm) and any associated symptoms or treatments. Ensure clinical notes support the diagnosis and site specificity for accurate coding.
