Chondromalacia, left shoulder

This code signifies the degeneration of articular cartilage on the undersurface of the patella within the left shoulder joint. It represents a softening and breakdown of the cartilage, leading to pain and dysfunction.

Apply this code when documentation explicitly states chondromalacia affecting the left shoulder. Supporting clinical notes should detail symptoms such as pain, crepitus, or limited range of motion localized to the left shoulder, and diagnostic findings confirming cartilage changes.

• Ensure the documentation specifies "chondromalacia" and clearly identifies the "left shoulder" as the affected site.
• Do not confuse with osteoarthritis (M19.-) unless the documentation explicitly states both conditions are present.
• Verify laterality; avoid using unspecified shoulder codes if the left shoulder is clearly documented.
