Chondromalacia patellae, right knee

This code signifies a diagnosis of chondromalacia patellae affecting the right knee. It describes a condition characterized by softening and breakdown of the cartilage on the undersurface of the kneecap (patella), leading to pain and dysfunction.

Apply this code when documentation explicitly states chondromalacia patellae of the right knee. This diagnosis is often made based on patient symptoms, physical examination findings, and sometimes imaging studies like MRI.

• Ensure laterality is clearly documented as "right knee" to support this specific code.
• Distinguish from other patellar tracking disorders or generalized osteoarthritis of the knee.
• Consider co-reporting with codes for associated symptoms like knee pain (M25.561) if documented.
