Calcium deposit in bursa, right knee

This code signifies the presence of calcific deposits within the bursa surrounding the right knee joint. This condition, often referred to as calcific bursitis, involves the accumulation of calcium salts, typically hydroxyapatite, within the synovial lining of the bursa, leading to inflammation and pain.

Apply this code when documentation clearly indicates calcification within a bursa of the right knee. This often presents with localized pain, tenderness, and swelling. Supporting documentation includes imaging reports (e.g., X-ray, ultrasound, MRI) confirming the presence and location of the calcium deposit.

• Ensure laterality is precisely documented and coded (right knee).
• Distinguish from calcific tendinitis (M65.2-), which involves tendons, not bursae.
• Code any associated bursitis (e.g., M70.5-) separately if documented as an acute or chronic inflammatory process.
