S82.54 Nondisplaced fracture of medial malleolus of right tibia

ICD-10-CM Code S82.54: Nondisplaced fracture of medial malleolus of right tibia

ICD-10-CM code S82.54 identifies a nondisplaced fracture of the medial malleolus of the right tibia. The medial malleolus is the bony prominence of the distal tibia on the inner side of the ankle. This specific code distinguishes the injury by both its lack of displacement and its right-side anatomical location. 2 3

Plain-language overview

The medial malleolus is the bony prominence located at the distal end of the tibia on the inner side of the ankle. A fracture of this specific anatomical structure is identified within the ankle joint. 2 3

What this code represents

Code S82.54 represents a nondisplaced fracture of the medial malleolus of the right tibia. This code is listed alongside other specific right ankle fractures, such as a displaced medial malleolus fracture of the right tibia designated as S82.51. 3

Coding details

The coding classification for right ankle fractures separates medial malleolus injuries by displacement status. The code S82.54 denotes a nondisplaced fracture, whereas S82.51 denotes a displaced fracture of the same right tibia structure. 3

Documentation considerations

The available coding reference lists distinct codes for nondisplaced and displaced right medial malleolus fractures. This listing demonstrates that documentation distinguishing displacement status and right laterality corresponds to different code selections. 3

Clinical context

Clinical literature describes the medial malleolus as the distal tibial structure forming part of the ankle mortise. The deltoid ligament originates from this medial malleolus and attaches to the talus, navicular, and calcaneus bones. 2

Medical literature notes that transverse medial malleolus fractures can be fixed using partially threaded screws or tension band wiring. In contrast, vertical medial malleolus fractures require buttressing fixation with an anti-glide plate. 2

What the sources add

The clinical anatomy source defines the medial malleolus as part of the distal tibia, while the coding source lists S82.54 as the corresponding right tibia fracture code. Together, these sources link the anatomical structure to its specific diagnostic classification. 2 3

A clinical trial protocol evaluates operative versus non-operative management of medial malleolus fractures in unstable ankle fractures. This research aims to determine differences in patient-reported outcomes one year after surgery between fixation and non-fixation approaches. 1
