A comminuted fracture is a type of closed fracture wherein the bone is shattered inside the soft tissue producing multiple fragments of bone inside. Since the history of the patient is a fall from a ladder, the corresponding ICD-10-CM code is W11.XXXD which translates to "fall on and from ladder, subsequent encounter". Since there is a calcaneal fracture (calcaneus is the bone of the sole of the foot), then the corresponding ICD-10-CM code is S92.002D which translates to "unspecified fracture of left calcaneus, subsequent encounter for fracture with routine healing".
