Chondromalacia, right ankle and joints of right foot

This code signifies the degeneration of articular cartilage on the posterior surface of the patella or other joint surfaces within the right ankle and/or right foot, characterized by softening, fraying, and fissuring. This condition often results in pain, swelling, and crepitus during movement of the affected joints.

Use this code when documentation clearly indicates chondromalacia affecting the right ankle joint, the talocrural joint, or any of the joints within the right foot (e.g., subtalar, tarsometatarsal, metatarsophalangeal, interphalangeal). Supporting documentation should include a physician's diagnosis based on clinical examination, imaging findings (e.g., MRI showing cartilage changes), or arthroscopic findings.

• Ensure the laterality is explicitly documented as "right" for both the ankle and foot joints.
• Do not confuse with osteoarthritis (M19.-) unless the chondromalacia has progressed to a full-blown arthritic condition.
• Code any associated pain (e.g., G89.11) or swelling (R60.0) separately if documented.
