Chondromalacia, unspecified site

This code signifies a softening of the cartilage, typically articular cartilage, without specifying a particular anatomical location. It represents a degenerative process where the cartilage loses its normal resilient texture, leading to pain and dysfunction.

Use this code when documentation clearly states "chondromalacia" but does not specify the affected joint (e.g., knee, patella, shoulder). This is appropriate when the physician has diagnosed chondromalacia but the exact site is either unknown or not documented.

• Avoid using this code if a specific anatomical site is documented; instead, use the more specific code (e.g., M22.4- for patellar chondromalacia).
• Ensure the medical record supports the diagnosis of chondromalacia, even if the site is unspecified.
• Consider querying the provider for a more specific site if possible, as this code is less precise.
