ICD-10-CM S52.189A: Other fracture of upper end of unspecified radius, initial encounter for closed fracture

ICD-10-CM code S52.189A represents an active diagnosis concept for an other fracture of the upper end of an unspecified radius during an initial encounter for a closed fracture. It is classified under the semantic type of Injury or Poisoning and has a parent concept of S52.189. General clinical sources describe radius fractures as frequent upper extremity injuries. 1 2 3

Plain-language overview

This diagnosis code identifies a specific type of upper extremity bone break, classified under the semantic type of Injury or Poisoning, for a patient receiving initial care for a closed fracture. 1 3

The code S52.189A specifically represents an other fracture of the upper end of an unspecified radius, initial encounter for closed fracture, and holds an active record status. 1

Coding details

Within the ICD-10-CM terminology, S52.189A is a narrower concept derived from the parent code S52.189, which denotes other fractures of the upper end of the unspecified radius. 1

An official published abbreviation for this specific diagnosis terminology is oth fracture of upper end of unsp radius, init for clos fx, providing a concise alternative for the full preferred name. 1

Clinical context

General clinical literature establishes that forearm fractures involving the distal radius are frequent, noting an incidence of around 67 upper extremity fractures per 10,000 people annually in the United States. 2

Clinical sources describe the distal radius as the portion of the bone closest to the wrist, which has the potential to fracture from a fall on an outstretched hand or other upper extremity trauma. 2

Documentation considerations

The official terminology record for S52.189A includes the full preferred name and a published abbreviation specifying an unspecified radius and an initial encounter for a closed fracture. 1

What the sources add

While the terminology records define the exact code boundaries and semantic type, the clinical text adds operational context by describing the general trauma mechanisms and incidence rates associated with radius fractures. 1 2 3

Both official terminology sources confirm the identical preferred name and Injury or Poisoning semantic classification for S52.189A, demonstrating consistent foundational data across different system views. 1 3
