ICD-10-CM code M24.24 identifies a disorder of a ligament in the hand. The terminology record is active for the 2026 version and classifies this concept as a disease or syndrome. Hand ligaments consist of tough connective tissue that stabilizes the numerous small bones and joints within the hand. 1 5

Plain-language overview

Ligaments in the hand consist of tough connective tissue that holds the hand's many small bones and joints together to facilitate normal joint movement. 5

What this code represents

The ICD-10-CM code M24.24 represents a diagnosis of a ligament disorder located in the hand, and the terminology record classifies this concept as a disease or syndrome. 1

Clinical context

Scapholunate dissociation is identified as the most frequent carpal instability, and a specific injury mechanism involves an extension and supination force pulling the scaphoid. 2

Diagnostic evaluations for hand ligament injuries may involve arthroscopy to assess instability, such as using a rocking chair sign to evaluate combined ligament injuries. 2

Documentation considerations

Clinical literature notes that scapholunate ligament injuries can present as avulsions or midsubstance ruptures, and about 13.4% of distal radius fractures are associated with scapholunate dissociation. 2

What the sources add

While the terminology sources define the code's hierarchical classification, the clinical literature provides operational context regarding specific injury mechanisms and diagnostic procedures for hand ligament instabilities. 1 2

The public health domain provides a general overview of hand injuries and disorders, while the clinical domain details specific surgical techniques like the three-ligament tenodesis for ligament reconstruction. 2 3
