S52.559C
ICD-10-CMOther extraarticular fracture of lower end of unspecified radius, initial encounter for open fracture type IIIA, IIIB, or IIIC
This code signifies an open fracture of the lower end of the radius, specifically located outside the joint capsule, where the bone has broken through the skin. The "unspecified" aspect indicates the laterality (left or right) of the radius is not documented. The "initial encounter" denotes that this code is used for the active treatment phase of the fracture, and the "type IIIA, IIIB, or IIIC" specifies a severe open fracture with significant soft tissue damage.
This code is appropriate for documenting the initial treatment of a patient presenting with a severe open fracture of the distal radius, not involving the joint surface, where the specific side of the injury is not yet recorded in the medical documentation. This would include scenarios such as emergency department visits, initial surgical repair, or the first inpatient admission for this injury.
