Unsp fx shaft of l rad, subs for opn fx type I/2 w malunion

This code indicates a fracture of the shaft of the left radius where the specific type of fracture (e.g., transverse, oblique) is not documented. It specifies that this is a subsequent encounter for a previously open fracture, classified as Type I or Type II, which has now healed incorrectly, resulting in a malunion.

This code is appropriate when a patient presents for follow-up care of a left radial shaft fracture that was initially an open fracture (Type I or II) and has subsequently healed in a misaligned or deformed position. It should be used for encounters occurring after the initial treatment of the fracture, where the malunion is the focus of the visit.

• Ensure documentation clearly states "malunion" and specifies the left radius shaft.
• Verify the original fracture was an open fracture, Type I or II, as this impacts the seventh character.
• This code is for subsequent encounters; do not use for the initial treatment of the fracture.
