M75.30 Calcific tendinitis of unspecified shoulder

Name of the Condition

• Calcific tendinitis of unspecified shoulder
• Also known as calcific tendinopathy or calcific shoulder bursitis

Summary

Calcific tendinitis of the unspecified shoulder is a condition marked by the deposition of calcium salts within the shoulder tendons, typically affecting the rotator cuff. This can cause pain, inflammation, and reduced shoulder mobility. The term "unspecified" indicates the shoulder side is not documented.

Causes

The exact cause of calcific tendinitis is not fully understood. It is thought to involve tendon degeneration, reduced blood flow, and metabolic imbalances that promote calcium deposition. Trauma or repetitive shoulder use may also contribute to its development.

Risk Factors

• Age: Most common in individuals aged 30-60 years.
• Gender: More prevalent in women than men.
• Repetitive shoulder activities or overhead motions.
• Underlying metabolic conditions such as diabetes.

Symptoms

• Severe shoulder pain, often worsening at night.
• Limited range of motion in the shoulder.
• Tenderness and swelling around the affected joint.
• A catching or clicking sensation during shoulder movement.

Diagnosis

Diagnosis involves a physical examination to assess pain and range of motion. Imaging tests, such as X-rays or ultrasound, confirm calcium deposits. MRI may be used to evaluate tendon involvement if needed.

Treatment Options

• Non-steroidal anti-inflammatory drugs (NSAIDs) to reduce pain and inflammation.
• Physical therapy to improve range of motion and strengthen shoulder muscles.
• Corticosteroid injections for severe pain or inflammation.
• Extracorporeal shock wave therapy to break up calcium deposits.
• Surgery (e.g., arthroscopy) for persistent symptoms or large deposits.

Prognosis and Follow-Up

Most cases improve with conservative treatment over several months. Follow-up may include monitoring pain levels, range of motion, and response to therapy. Severe or refractory cases may require ongoing management.

Complications

• Chronic shoulder pain or stiffness.
• Reduced shoulder function affecting daily activities.
• Tendon rupture in rare cases.

Lifestyle & Prevention

• Avoid repetitive overhead motions or modify activities to reduce strain.
• Maintain shoulder strength and flexibility through regular exercise.
• Use proper form during physical activities to minimize injury risk.

When to Seek Professional Help

Seek care if shoulder pain is severe, persistent, or worsening; if movement is significantly restricted; or if symptoms interfere with daily tasks.

Tips for Medical Coders

Document the affected shoulder side when possible for specificity. For M75.30, use when the shoulder side is not documented. Ensure clinical documentation supports the diagnosis and treatment provided.
