Chondromalacia, right wrist

This code represents the degeneration of articular cartilage on the posterior surface of the patella, or other joint, specifically affecting the right wrist. This condition is characterized by softening and breakdown of the cartilage, leading to pain, crepitus, and functional impairment in the wrist joint.

Use this code when documentation clearly indicates chondromalacia affecting the right wrist. This diagnosis is typically supported by clinical examination findings such as localized pain, tenderness, and crepitus, often confirmed by imaging studies like MRI showing cartilage irregularities.

• Ensure laterality is explicitly documented as "right wrist" to support this specific code.
• Distinguish from other wrist arthropathies; chondromalacia implies cartilage softening without significant inflammatory or erosive changes.
• Do not confuse with osteoarthritis (M19.-), which involves more extensive joint degeneration and bone changes.
