M24.13 Other articular cartilage disorders, wrist

ICD-10-CM Code M24.13: Other articular cartilage disorders, wrist

ICD-10-CM code M24.13 identifies other articular cartilage disorders of the wrist, functioning as an active diagnostic concept classified under the broader parent category of other articular cartilage disorders. The terminology denotes a disease or syndrome, while clinical evaluation of wrist cartilage remains challenging due to complex anatomy and small tissue sizes. 1 2

Plain-language overview

Code M24.13 designates other articular cartilage disorders located in the wrist, providing a standardized diagnostic label for this specific joint condition. 1

What this code represents

The terminology record classifies M24.13 with the semantic type of disease or syndrome, establishing it as a diagnosis or health-status concept rather than a procedure or external cause. 1

Coding details

Within the ICD-10-CM hierarchy, M24.13 is a child concept of M24.1, which represents other articular cartilage disorders, and the M24.13 record currently lists no narrower concepts. 1

The official preferred name for M24.13 is other articular cartilage disorders, wrist, and this exact label is also documented as the published abbreviation for the code. 1

Clinical context

The wrist is a challenging anatomic area to examine via magnetic resonance imaging because the tissues are small, including thin articular cartilage at multiple locations and the triangular fibrocartilage complex. 2

T2 and T2* mapping are feasible for compositional imaging of wrist cartilage at both 3 and 7 Tesla, but clinical interpretation remains difficult due to variations between anatomic locations and field strengths. 2

Documentation considerations

Clinical literature indicates that wrist articular cartilage is small and located at multiple anatomic sites, and that T2 and T2* values vary by anatomic location at 3 and 7 Tesla. 2

What the sources add

While the terminology record provides the official code definition and active status, the imaging research excerpt adds operational context regarding the clinical difficulty of visually assessing the small cartilage structures in the wrist. 1 2

Coverage and utilization context

The supplied terminology records establish the code's classification and active status, but they do not contain payer-specific rules or imply that assigning M24.13 guarantees healthcare coverage. 1 3
