Chondromalacia, joints of left hand

This code signifies the degenerative softening and breakdown of articular cartilage within the joints of the left hand. This condition leads to pain, stiffness, and impaired joint function, often due to overuse, trauma, or underlying inflammatory processes.

Apply this code when documentation explicitly states chondromalacia affecting any joint(s) of the left hand. This diagnosis is typically supported by clinical examination findings, patient symptoms, and sometimes imaging studies like MRI.

• Ensure laterality is clearly documented as "left hand" to support this specific code.
• Distinguish from osteoarthritis (M19.-) which involves broader joint degeneration, though chondromalacia can be a precursor.
• Do not use for chondromalacia affecting other sites; specific codes exist for knee (M94.26-) and other joints.
