ICD-10-CM S93.305A: Unspecified Dislocation of Left Foot, Initial Encounter

ICD-10-CM code S93.305A identifies an unspecified dislocation of the left foot during an initial encounter. This active diagnosis concept belongs to the injury or poisoning semantic type and exists within a broader category of left foot dislocations. The terminology record distinguishes this initial encounter from subsequent and sequela variants. 1 3

Plain-language overview

Code S93.305A serves as an active terminology concept representing an unspecified dislocation of the left foot for an initial encounter, providing a standardized diagnostic label for clinical documentation. 1

What this code represents

The terminology record classifies S93.305A under the semantic type of Injury or Poisoning, establishing the diagnosis as an injury-related health condition rather than a routine medical disease. 1

Code S93.305A is a narrower concept derived from the parent code S93.305, which denotes an unspecified dislocation of the left foot without specifying the encounter stage. 1

Coding details

Code S93.305A appears within a reference list of foot and ankle diagnoses that includes distinct laterality and joint specifications, such as dislocation of the tarsometatarsal joint of the left foot. 4

Documentation considerations

Clinical references note that Lisfranc fracture-dislocations of the left foot involve midfoot injuries that are frequently missed, indicating that precise documentation of clinical and radiographic findings is critical. 2

What the sources add

While the terminology record defines the code's structural hierarchy, the clinical text adds context that left foot dislocations can involve complex tarsometatarsal joint disruptions leading to chronic pain if inadequately managed. 1 2

The terminology record establishes the official label and active status, whereas the orthopedic reference provides operational context by listing S93.305A alongside other specific left foot dislocation codes. 1 4
