M71.40 Calcium deposit in bursa, unspecified site

Name of the Condition

• Calcium deposit in bursa, unspecified site

Summary

Calcium deposit in bursa, unspecified site, refers to the presence of calcium deposits within a bursa (a small fluid-filled sac that reduces friction between tissues) without specifying the anatomical location. This condition may cause localized pain, swelling, or functional impairment, though symptoms can vary depending on the size and location of the deposit.

Causes

Calcium deposits in bursae can result from chronic inflammation, repetitive motion, or trauma to the affected area. Metabolic conditions, such as hyperparathyroidism, or localized tissue damage may also contribute to deposit formation. The exact cause often remains unclear, as deposits can develop without obvious injury.

Risk Factors

• Repetitive or prolonged pressure on bursae (e.g., from kneeling, leaning)
• Occupational or athletic activities involving repetitive joint use
• Pre-existing inflammatory conditions (e.g., rheumatoid arthritis)
• Age-related degenerative changes
• Metabolic disorders affecting calcium metabolism

Symptoms

• Localized pain or tenderness over the affected bursa
• Swelling or palpable lump at the site
• Reduced range of motion in adjacent joints
• Discomfort with movement or pressure
• Possible warmth or redness if inflamed

Diagnosis

Diagnosis typically involves a physical examination to assess bursal characteristics, along with imaging (e.g., X-ray, ultrasound, or MRI) to identify calcium deposits. Fluid aspiration may be performed to rule out infection or other conditions, and laboratory tests may be used to evaluate metabolic factors if indicated.

Treatment Options

Treatment may include rest, ice, and anti-inflammatory medications to reduce pain and swelling. Physical therapy can help improve mobility and strength. In some cases, corticosteroid injections or surgical removal of the deposit may be considered for persistent symptoms.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate treatment, though symptoms may recur if underlying risk factors persist. Follow-up care may involve monitoring for symptom improvement and addressing contributing factors, such as activity modifications or metabolic management.

Complications

Complications can include chronic pain, reduced joint function, or infection if the deposit becomes irritated or ruptures. Rarely, large deposits may cause nerve compression or tissue damage.

Lifestyle & Prevention

• Avoid repetitive motions or prolonged pressure on bursae
• Use protective padding during activities that stress joints
• Maintain a healthy weight to reduce joint stress
• Engage in regular stretching and strengthening exercises
• Address underlying inflammatory or metabolic conditions

When to Seek Professional Help

Seek medical attention if symptoms worsen, persist despite home care, or interfere with daily activities. Prompt evaluation is recommended if there is significant swelling, redness, fever, or signs of infection.

Tips for Medical Coders

When coding for calcium deposit in bursa, unspecified site (M71.40), ensure documentation supports the presence of calcium deposits in a bursa without specifying the anatomical location. Verify that the diagnosis aligns with clinical findings and imaging results, and avoid using this code if a more specific site is documented.
