S52.326Q
ICD-10-CMNondisplaced transverse fracture of shaft of unspecified radius, subsequent encounter for open fracture type I or II with malunion
This code describes a transverse fracture of the shaft of the radius that was initially an open fracture (Type I or II) and is now being treated for malunion. "Nondisplaced" refers to the initial fracture alignment, while "malunion" indicates that the bone has healed in an incorrect anatomical position. This code is used for subsequent encounters after the initial treatment of the fracture.
This code is appropriate when a patient presents for follow-up care of a previously treated open transverse radial shaft fracture (Type I or II) that has healed with a deformity. This includes situations where the malunion is being evaluated, monitored, or undergoing further intervention. It should be used for any encounter after the initial fracture care where malunion is the focus.
