Chondromalacia, right knee

This code signifies the softening and breakdown of the articular cartilage on the undersurface of the patella (kneecap) in the right knee. This condition typically results in pain, crepitus, and sometimes swelling, particularly with activity or prolonged sitting.

Apply this code when documentation clearly indicates a diagnosis of chondromalacia affecting the right knee. This diagnosis is often made based on clinical examination findings such as patellofemoral pain, tenderness, and crepitus, and may be supported by imaging studies like MRI showing cartilage changes.

• Ensure the laterality (right knee) is explicitly documented.
• Distinguish from other patellofemoral pain syndromes or osteoarthritis, which have different codes.
• Consider co-reporting with codes for underlying causes or associated conditions, such as patellar instability or malalignment, if documented.
