Chondromalacia, other site

This code signifies chondromalacia affecting an anatomical site other than the patella. It describes a condition characterized by the softening and degeneration of articular cartilage, leading to pain, swelling, and impaired joint function in a non-patellar joint.

Apply this code when documentation specifies chondromalacia in a joint such as the shoulder, hip, ankle, or wrist. This diagnosis is supported by imaging findings (e.g., MRI) and clinical assessment indicating cartilage damage in a joint other than the knee.

• Ensure the documentation explicitly states a non-patellar joint is affected; otherwise, a patellar chondromalacia code (M22.4-) may be more appropriate.
• Do not use this code for generalized osteoarthritis, even if cartilage degeneration is present; specific osteoarthritis codes should be used instead.
• Always review the medical record for laterality (e.g., right, left, bilateral) if specified, as some chondromalacia codes require this detail.
