Chondromalacia, left knee

This code signifies chondromalacia affecting the left knee. Chondromalacia is a condition characterized by the softening and breakdown of the cartilage on the undersurface of the patella (kneecap), leading to pain and dysfunction.

Use this code when documentation explicitly states chondromalacia of the left knee. This diagnosis is often made based on patient symptoms (e.g., anterior knee pain, crepitus), physical examination findings, and sometimes imaging studies like MRI.

• Ensure laterality is clearly documented as "left knee" to support this specific code.
• Distinguish from other knee cartilage disorders, such as meniscal tears or osteoarthritis, which have different codes.
• Look for documentation of the severity or grade of chondromalacia if available, though it doesn't change this specific code.
