Other specified disorders of cartilage, thigh

This code signifies a non-traumatic, non-inflammatory, and non-degenerative condition affecting the cartilage of the thigh that is not specifically classified elsewhere. It encompasses various rare or unusual cartilage disorders of the femur or surrounding structures within the thigh region.

Use this code when documentation clearly indicates a specified but uncommon disorder of the thigh cartilage, such as chondromalacia not otherwise specified, or other atypical cartilage lesions that don't fit more specific ICD-10-CM codes. Supporting documentation should detail the specific nature of the cartilage abnormality and its location within the thigh.

• Ensure the documentation specifies "thigh" as the anatomical site; otherwise, a more general site code may be appropriate.
• Distinguish from M22.4X_ (Chondromalacia patellae) or M94.2_ (Chondromalacia, other sites) if the condition is specifically patellar or affects a different joint.
• Always look for more specific codes first; this is a residual category for conditions not precisely defined elsewhere.
