S92.909 Unspecified fracture of unspecified foot

ICD-10-CM Diagnosis Code S92.909: Unspecified Fracture of Unspecified Foot

ICD-10-CM code S92.909 designates an unspecified fracture of an unspecified foot, functioning as an active diagnosis concept categorized under an injury or poisoning semantic type. While this specific code lacks detailed clinical specificity, related clinical sources describe foot stress fractures as bone breaks resulting from repeated stress rather than sudden trauma. 1 2 3

Plain-language overview

Code S92.909 identifies an unspecified fracture of an unspecified foot, serving as an active terminology record within the ICD-10-CM version 2026 diagnostic classification system. 1

What this code represents

The S92.909 diagnosis concept belongs to the broader parent concept S92.90, which denotes an unspecified fracture of the foot, and currently has no narrower subordinate concepts in the terminology. 1

The semantic classification assigned to the S92.909 diagnosis concept is Injury or Poisoning, establishing the fundamental clinical nature of this specific unspecified foot fracture code. 1

Clinical context

Clinical literature describes a stress fracture as a bone break caused by repeated stress, distinguishing it from an acute fracture resulting from a sudden traumatic injury. 3

The foot and ankle complex represents a frequent site for stress fractures, with metatarsal fractures accounting for thirty-eight percent of all stress fractures observed in athletes. 2

Documentation considerations

Clinical evidence indicates that an x-ray may not reveal a stress fracture for up to six weeks after the injury occurs, which may impact the timing of diagnostic imaging results. 3

A related terminology record for a subsequent encounter code specifies documentation of an unspecified foot fracture with nonunion, illustrating a distinct healing complication category. 4

What the sources add

Comparing the sources reveals that while the terminology record provides the official S92.909 code definition, the clinical excerpts add general context regarding stress fracture causes and diagnostic imaging limitations. 1 3

Coverage and utilization context

The available sources establish the official terminology definition and general clinical context for foot fractures, but provide no payer-specific coverage guidelines or utilization rules for the S92.909 diagnosis code. 1 2 3
